Government of India today gave formal permissions to Telecom Service Providers (TSPs) for conducting trials for use and applications of 5G technology. The applicant TSPs include Bharti Airtel Ltd., Reliance JioInfocomm Ltd., Vodafone Idea Ltd. and MTNL. Notably, Chinese telecom giant Huawei which was one of the applicant has been excluded.
The press note from DoT said that the selected TSPs have tied up with original equipment manufacturers and technology providers which are Ericsson, Nokia, Samsung and C-DOT. In addition, Reliance JioInfocomm Ltd. will also be conducting trials using its own indigenous technology.
The permissions have been given by DoT as per the priorities and technology partners identified by TSPs themselves. The experimental spectrum is being given in various bands which include the mid-band (3.2 GHz to 3.67 GHz), millimeter wave band (24.25 GHz to 28.5 GHz) and in Sub-Gigahertz band (700 GHz). TSPs will also be permitted to use their existing spectrum owned by them (800 MHz, 900 MHz, 1800 MHz and 2500 MHz) for conduct of 5G trials.
The duration of the trials, at present, is for a period of 6 months. This includes a time period of 2 months for procurement and setting up of the equipment.
The DoT has also made it clear that that objectives of conducting 5G trials include testing 5G spectrum propagation characteristics especially in the Indian context; model tuning and evaluation of chosen equipment andvendors; testing of indigenous technology; testing of applications (such as tele-medicine, tele-education, augmented/ virtual reality, drone-based agricultural monitoring, etc.);and to test 5G phones and devices.
DoT has further specified that the trials will be isolated and not connected with the existing networks of TSPs. Trials will be on non-commercial basis. The data generated during the trials shall be stored in India. TSPs are also expected to facilitate the testing of the indigenously developed use cases and equipment as part of the trials.
Why is 5G important?
5G technology is expected to deliver improved user experience in terms of data download rates (expected to be 10 times that of 4G), up to three times greater spectrum efficiency, and ultra low latency to enable Industry 4.0. Applications are across a wide range of sectors such as agriculture, education, health, transport, traffic management, smart cities, smart homes, and multiple applications of IOT (Internet of Things).


At the point when MapReduce was first published it noted the use of data locality mechanism for avoiding network transfer and therefore avoid a possible bottleneck. In their paper they were using a network bandwith of 100 MBit/s, which where totally common at this time, but nowadays 10 GBit/s networks are cheap and widely available [Chap 3+3.4].
So the question is: Is avoiding network traffic especially in Big Data processing still needed?
Let’s assume following:
We have 4 physical servers, which on each HDFS Datanode has 5 physical 10rpm SAS disks. The manufacturer of the disks notes that this disks will provide a 237 MiB/s sustained transfer speed. In Big Data, generally sustained read performance of huge data is more important than fast disk access.
So following theoretical properties are given:
- Physical Node Network Bandwith: 10 GBit/s = 1250 MB/s
- Max Sustained Transfer Speed per Datanode: 237 MiB/s * 5 = 1185 MiB/s = 1242,56 MB/s
➡ 1250 MB/s per Node Network Bandwith > 1242,56 MB/s Max Sustained Transfer Speed per Datanode
So in this case the maximal possible sustained data transfer of all disks combined of a Datanode is less than the available network bandwith and therefore our limiting factor. And yes, big data network transfer isn’t the only data which will be transferred over a network but should be the largest share. Also at this point at TIKI, the HDFS Cluster and there Datanodes are oversized according to the performance. No data processing or any other machine learning job ever succeeded in bottlenecking or hitting the limit of the theoretical speed limit of the HDFS Datanodes. We noticed that we are heavily bottlenecked by algorithms and CPU power. As long as the HDFS performs fast enough and every Datanode is planned that the maximal network bandwith cap can never be achieved, the network bandwith as a resource will never be bottlenecked and data locality as a solution for this can be ignored.
To be clear, this only applies to node based data locality. When having a large cluster with several racks or maybe multiple connected data centers, the network connection in between them are often a magnitute slower than the switched connection within a rack. So avoiding transfering data over this connection will still be a huge improvement, but most distributed file systems have already an integrated concept and implementation for this.
So the last open question is: Would having node based data locality bring any performance improvements? Maybe the network stack will add some latency?
On a normal side-by-side Hadoop Cluster installation with Apache Spark data locality would work out of the box, but at TIKI we use Kubernetes based distribution solution with Apache Spark 3.0 where the HDFS is managed and installed manually as a Daemonset. Due to the fact that worker Pods, which executes the Spark job workload, gets different IP adresses than the HDFS Data Nodes the default IP based mapping wouldn’t work, so we had to implement a custom solution for this. This was done by my collegue Linus Meierhöfer and he explained the implementation here.
In my experiment I wanted to compare two data processing scenarios:
- All data is fetched and processed locally on the same physical machine
- All data is transfered over a network interface to a second physical machine
To achieve this I duplicated my test data sets and replicated one of them on all physical machines and for the other test data set I set the replication factor to 1 and manually verified that all data blocks exists only on one specific machine.
Then I started my experiment spark workloads which just reads the data and processing the data with different generic ways:
- do statistical aggregations (describe)
- counting every rows existing in the dataset (rowcount)
- filtering for a specific column and counting the distribution of its nominal values (distribution)
All this workloads were executed on the same dataset but with different formats and compressions. The dataset itself contains ~10ˆ9 records each consisting of 29 columns.
Each workload has been repeated 5 times itself and following metrics have been monitored:
- Network traffic of the physical server interfaces
- Disk read access of the HDFS physical diskds
- Wall time of the workloads
The next graph shows the monitored network traffic and the HDFS disk node access. The red dotted vertical line separates the experiment with data locality (left half) and the experiment without (right half). Which shows that no data has been sent over the network and the data has been read from the Node 1.
The right half shows that in the experiment without data locality the data has been read from Node 2 and then transferred to Node 2 where it was processed by the spark job. This graph just shows that the data locality avoided the network traffic completely.

There is a universal consensus that 5G wireless technology will be a game changer to close the digital divide. The question is whether or not private investment will be enough to deploy the necessary infrastructure. A new report shows that capital expenditures from wireless providers will reach a record high in 2021, as 5G sees tremendous growth and will continue to help connect households currently not served by broadband.
CTIA’s 2022 Annual Wireless Industry Survey shows that wireless providers are investing $35 billion to grow and upgrade their networks, the fourth consecutive year of industry growth.
CTIA said this is “a strong trend that emphasizes the social importance of wireless connectivity and underscores the industry’s commitment to building a strong platform for innovation that connects all communities.”
5G has experienced a quantum leap in growth since it was first launched in 2018, as infrastructure reforms that eased deployment barriers caused 5G to grow twice as fast as 4G. As the Federal Communications Commission and state legislatures work to modernize regulations on key sites that could hamper the technology’s growth, wireless providers have added 70,000 active cell sites. There are currently nearly 420,000 operational cell sites in the United States
As CTIA notes, “More cell sites improve coverage, encourage adoption and help close the digital divide.”
Clearly consumers want faster mobile internet speeds as the number of connected 5G devices has grown by more than 500 percent in the past year from 14 million to Accenture’s 85 million. About a third of Americans now have an active 5G device.
CTIA points out that the number of connections requiring wireless technology is helping its growth – everything from smart watches to medical sensors. Such data measuring devices represent about 42 percent of all wireless connections.
Wireless providers have invested nearly $121 billion into their networks since the launch of 5G.
CTIA said that in an era of tremendous inflation, the wireless industry’s investment, combined with increased market competition, has led to lower prices, “providing a welcome contrast to an economy where consumers have experienced price increases for 94 percent of goods and services tracked across the .”
Since 2010, the cost of unlimited data plans has dropped 43 percent while wireless speeds have increased 85-fold over the same period.
Investment and competition have also led to new innovations such as 5G for home broadband and 5G fixed wireless. The latter is particularly useful for connecting rural areas where it is difficult to make a fiber business case due to long-distance connection costs. CTIA says 5G home broadband is available in more than 40 million households, providing home connections across the spectrum with high capacity and low latency rather than wired connections.
The report also shows that 5G helps reduce the impact of climate change by creating green jobs in key industries. Accenture found that 5G-enabled use cases should deliver 20 percent of US emissions reduction targets by 2025.
5G is clearly helping usher in a new era of connectivity in this country. CTIA statistics are encouraging signs that the latest wireless technology is helping to bring broadband access to more Americans than ever before. The best part of this growth is that taxpayer dollars are not wasted.

A journey building drones and ROVs and other open hardware and Arduino based stuff
While testing the Arducopter I’ve seen that soon after the first basic tests with the Mission Planner and the USB, testing with a real power supply was needed. But I didn’t want to charge and re-charge my LiPo batteries just for testing on the bench. The same problem with the radio tx: it runs on 8 stilo AA batteries, and spending 10€ for a day of testing the TX seems a bit too much.
So I decided to make two cables to allow powering both the radio and the copter from my bench power supply.
I basically created 2 power cables, one that goes into the battery socket and one that goes into the radio power plug: on one side the respective plugs and sockets (a JST connector for the radio and a XT60 connector for the battery) and on the other side two banana plugs that go into the power supply.
Actually for the TX I adapted the one I used for testing the OpenROV.
As you can see from the pictures, the routing of ESCs/Motors cables and APM to receiver is still a bit messy, just as I left it after the last : I just wanted to see if everything was working before tidying up everything. Also I need to find a way to fix the APM to the frame and still keep some space for the received.


Mastering iPhone Connectivity: Preventing Auto-Switching from Wi-Fi to Cellular Data
In our increasingly connected world, smartphones have become necessary tools for both work and personal life. The iPhone, in particular, offers seamless connectivity with its ability to switch between Wi-Fi and cellular data networks. However, some users may find that their iPhones automatically switch from Wi-Fi to cellular data, resulting in unexpected data usage and potentially increased costs.

192.168.1.1 IP address
is the default gateway of most wireless routers or ADSL modems.
There are several IP main addresses a router can take, 192.168.l.l is the most common one though 10.0.0.1 or 192.168.0.1 are also other options.
These are commonly known as a host addresses.
The 192.168.1.1 IP address is normally used by Linksys broadband router and sometimes by other brands of network routers or home network gateway equipment .
Network administrators use this address to help set up a new router or update settings for an existing one.
The same address can also be used on business computer network .
Technically a computer, printer or another device can be set up to use this address instead of a router although that’s not a recommended network setup as it can easily lead to IP address conflicts .
192.168.1.1 belongs to the private IP address range that starts with 192.168.0.0 and extends through 192.168.255.255.

At Meltwater we use RabbitMQ for messaging. We have several clusters and had a need for a new cluster. This made us ask the question: how is the message rate affected by the hardware chosen for the cluster? Should we go for more CPU cores? Or maybe faster disks? Are there other things to consider to get the best performance out of RabbitMQ? This blog post tries to answer those questions.
TL;DR Increasing the number of CPU cores or increasing the disk speed has only a limited impact on the throughput of a RabbitMQ cluster with HA queues and persistent messages. All queues should have the same node as master, and all publishers and consumers should connect to the queue master node for best performance.
To be able to quickly set up a test environment, we chose to set up the tests on AWS EC2, using different instance types. The instance types used can be seen in the table below. The network performance between the cluster nodes was measured using iperf.
|Instance type||CPU cores||Hyper-threads||CPU speed (MHz)||Memory (GB)||Network (Gbit/s)|
In all tests, we used two instances of the same instance type to build a RabbitMQ cluster. For generating load, we used a r3.2xlarge instance running the RabbitMQ Java client PerfTest tool. For all tests, SSD instance storage was used.
In all tests, the test queues were using HA mode, and all messages were persisted. In the tests with one queue, there were 10 producers and 10 consumers on that queue. In the tests with 10, 20 and 30 queues, there was one producer and one consumer per queue. All message rates below are messages per second over all queues. Other test properties can be seen in the table below.
|Test time||60 s|
|Message size||4000 B|
Adding CPU cores
To determine how the performance varied with the number of cores, we tested three different instance types with 2, 4 and 8 CPU cores, each with 2 hyper-threads (r3.xlarge, r3.2xlarge and r3.4xlarge).
The performance improvements were modest when doubling the number of cores. When going from 2 to 4 cores, the message rate increased by only 13% (from 5500 to 6200) in a test with one queue. Doubling the number of cores again from 4 to 8, the message rate increased by only 10% (from 6200 to 6800). Similar results were found in tests with 10, 20 and 30 queues. In some cases, the performance was worse with more cores, as can be seen in the figure below.
To be able to determine how RabbitMQ would perform in a situation where the consumers were not able to keep up, we also ran a test where 10 queues had 500,000 messages in them when the test started. When doubling the number of cores (from 4 to 8) the publishing message rate more than doubled (from 1750 to 5000) and consumption message rate increased by about 10% (from 17,000 to 20,000), see figure below. In other words, it seems that the number of CPU cores has a larger impact on performance when queues are large than when queues are empty.
Increasing CPU speed
Another question we had was how CPU speed would affect the message rate. Therefore, we compared r3 instances using 2500 MHz CPUs with c3 instances using 2900 MHz CPUs. The test results on c3.2xlarge instances with 4 faster CPU cores were similar to the results of the r3.4xlarge instances with 8 slower CPU cores, i.e. no large impact on performance.
Increasing disk performance
We wanted to know if an increased disk speed would affect performance. We therefore set up two clusters with c3.2xlarge instances. In one of the clusters, we only used one of the two 80 GB SSD disks. In the other cluster, we set up RAID 0 using the two SSD disks, to get better write and read performance. The write-speed increased by 60% from 800MB/s to 1.3GB/s.
The performance increase of the RabbitMQ cluster was modest also in this case. With one queue the message rate increased by 5% (from 6600 to 6900). With 10 queues the increase was also 5% (from 9000 to 9500).
Increasing network performance
To test how the message rate was affected by the network performance we tested both with different latencies and different network throughputs between nodes. The latency within an AWS availability zone is smaller than between zones. Having the cluster nodes in the same availability zone or in different zones showed no significant difference in our tests. To see if the network throughput between the cluster nodes was the bottleneck, we used instance types with different bandwidth. In our test, r3.4xlarge had twice the network throughput compared to the r3.2xlarge instance, but the message rate was similar, as can be seen in the first graph.
Where to connect?
As has been observed by others, the message rate is a lot better if the publishers and consumers connect to the master node of the queue. In our tests, the message rate more than halved (from 6200 to 3000) in a test with one queue, and the message rate decreased by 40% (from 8000 to 5000) in a test with 10 queues. The message rates are worse in any configuration where consumers or publishers connect to the queue slave node.
Spreading the load
Finally, we wanted to know if the performance would increase if the load was spread over the two nodes by dividing the queues evenly between the nodes. Producers and consumers then connected to the queue master node. In a test with 30 queues the message rate decreased by 20% (from 7500 to 6000).
If you have a RabbitMQ cluster with HA queues and persistent messages, the following applies:
- Doubling the number of CPU cores has a larger impact on throughput when queues are large.
- Improving the disk write speed by configuring RAID 0 only improves the message rate marginally.
- When connecting to a queue slave node, message rates can in the worst case be halved.
- Spreading the load by distributing queues and connections to both cluster nodes decreases performance.


Alarm and monitoring systems
Systems of the type Modicon 984 - A120 are used for the monitoring of machinery equipment onboard of container vessels, megayachts and specialized vessels.
The input of various types of sensors, such as binary NC/NO, 0/4-20 mA, 0-10Volt, thermoelements, Pt 100/ Pt 1000, can be evaluated and processed.
These systems are mainly used for watchless vessel operation.
A standby alarm system and an engineer call system are integrated into the unit. Larger systems may be equipped with various substations to which the sensors can be connected. The exact number of substations may be chosen by the customer in order to optimize the vessel’s cable system.
The substations are preferably equipped with the highly compact assembly units offered by Wago. Data exchange between the main station and its substations is carried out via a CAN Bus coupling. The main CPU as well as the respective visualization systems are equipped with assembly units and displays by Schneider Electric.
The controls for standby pumps can be integrated into the alarm system in order to optimize the cable system even further.
The system comes equipped either with 11“ TFT touchscreen displays or with a conventional keyboard. Column diagrams displaying temperature, filling level or pressure can be easily configured. Threshold values may be set via the display. Average exhaust gas measuring systems are standard for watchless vessels.
Should a larger number of graphics for trend curves, operation time counters, etc... be required, PC systems by HP with special marine kits are used. The type and size of the monitors may be chosen by the customer.
We have equipped several megayachts with analogue measurement instruments on an 18“ monitor integrated into the bridge console. As design is of maximum importance with yacht bridge consoles and the analogue indicators frequently do not conform to the designer’s vision, this solution was chosen and approved by the classification society Lloyd’s Register.
All systems for watchfree operation are equipped with a disturbance printer.
The systems are suitable for connection to the 24 Volt automation network. If the vessel is equipped with a 220 Volt PC system, we offer USV units as an option.

In the vast world of audio technology, microphones stand as unsung heroes, transforming sound waves into electrical signals. Whether you’re an aspiring musician, a podcaster, or simply intrigued by the mechanics of sound capture, understanding how microphones work is key to harnessing their potential.
Microphones, commonly known as mics, are devices that convert acoustic energy (sound) into electrical signals. These signals can then be amplified, recorded, or transmitted for various purposes.
Delving into the intricacies of microphone functionality allows users to make informed choices, optimize performance, and troubleshoot issues effectively.
Explore the detailed comparison between Shure MV7 and SM7B to make an informed decision about your next microphone upgrade: Shure MV7 vs SM7B models.
Table of Contents
Types of Microphones
Microphones come in various types, each with its unique design and functionality, catering to different recording scenarios and preferences. Understanding the intricacies of these microphone types can significantly impact the quality of audio capture in specific situations.
Dynamic microphones are renowned for their robust build and versatility. Operating on the principle of electromagnetic induction, these mics boast a diaphragm attached to a coil within a magnetic field. When sound waves hit the diaphragm, it moves the coil, generating an electrical current. Dynamic microphones are ideal for high-volume environments, making them a preferred choice for live performances and recording loud instruments due to their ability to handle loud sound sources with minimal distortion.
Condenser microphones, in contrast, utilize a diaphragm placed close to a backplate, forming a capacitor. Sound waves cause variations in the distance between the diaphragm and backplate, resulting in electrical changes. Known for their sensitivity and ability to capture a broad frequency range, condenser microphones are commonly used in studio settings for vocals and nuanced sound sources. They excel in delivering detailed and high-quality audio recordings.
Ribbon microphones employ a thin strip of metal (the ribbon) suspended in a magnetic field. When sound waves move the ribbon, it generates an electrical current. Recognized for their warm and natural sound reproduction, ribbon microphones are often chosen for capturing the subtle nuances in audio. While they may require careful handling due to their delicate nature, their unique sonic characteristics make them valuable in specific recording applications.
To comprehend the intricate workings of microphones, it’s essential to explore the fundamental components that collaborate to transform sound waves into electrical signals.
- Diaphragm. The diaphragm serves as the microphone’s sensory organ, a thin and responsive material that vibrates in response to incoming sound waves. Its ability to move in sync with these vibrations is critical for initiating the signal conversion process.
- Coil or Capacitor. In both dynamic and condenser microphones, the coil or capacitor plays a pivotal role in converting mechanical vibrations into electrical signals. In dynamic microphones, the movement of the coil within a magnetic field generates an electrical current, while in condenser microphones, variations in the capacitor’s electrical charge occur.
- Magnet. The magnet is a key component that creates a magnetic field. This field interacts with the coil or capacitor, facilitating the generation of an electrical current. The strength and configuration of the magnet influence the microphone’s overall performance.
- Housing. While often overlooked, the housing of a microphone is crucial. It protects the delicate internal components from external elements and influences the microphone’s durability, design, and overall aesthetic. The housing can impact the microphone’s ability to reject unwanted noise and contribute to its overall sound signature.
In the realm of microphones, polar patterns play a pivotal role in defining how a microphone captures sound from different directions. Understanding these patterns is crucial for achieving optimal audio results in various recording scenarios.
- Omnidirectional. Omnidirectional microphones exhibit a 360-degree sensitivity, capturing sound equally from all directions. While versatile, these microphones are susceptible to picking up background noise, making them ideal for controlled environments where ambient sounds are minimal.
- Cardioid. Cardioid microphones focus on capturing sound primarily from the front, forming a heart-shaped sensitivity pattern. This design minimizes noise from the sides and rear, making cardioid microphones ideal for isolating a specific sound source in a noisy environment.
- Bidirectional. Bidirectional, or figure-eight, microphones are sensitive to sound from the front and rear while rejecting sound from the sides. This pattern is beneficial for scenarios like interviews where the microphone can capture two opposite-facing sources simultaneously.
- Hypercardioid. Hypercardioid microphones have a more concentrated front sensitivity compared to cardioid patterns, further minimizing side and rear sound pickup. This makes them suitable for environments where isolating a specific sound source is crucial, such as on-stage performances.
Microphones offer various connection options, impacting both compatibility and functionality. USB microphones, designed for simplicity, serve as plug-and-play devices, catering to beginners and individuals focused on computer-based recording. On the other hand, XLR microphones deliver a caliber of audio quality suitable for professional applications, finding common usage in both studio settings and live performances. The choice between USB and XLR connections depends on the user’s specific needs, with USB providing convenience and accessibility, while XLR ensures a higher standard of audio performance, meeting the demands of more advanced recording environments.
Careful placement of microphones is essential to attain superior sound quality and diminish undesirable noise. Experimenting with positioning to discover the optimal “sweet spot,” taking room acoustics into account, and incorporating pop filters to mitigate plosive sounds are strategic approaches. Achieving the perfect microphone placement involves a thoughtful consideration of the recording environment, utilizing experimentation and acoustic adjustments. These practices contribute to the creation of clear and high-quality audio recordings while effectively managing potential challenges associated with ambient noise and vocal nuances.
Common Issues and Troubleshooting
Addressing background noise involves optimizing recording environments, using noise reduction tools, and selecting the right microphone type.
Distortion issues may arise from excessive input levels; adjusting gain settings and maintaining appropriate distances can help mitigate distortion.
Low volume problems might be solved by checking cable connections, adjusting input levels, and ensuring proper microphone sensitivity.
Consistent microphone maintenance is imperative for sustained optimal performance. Routinely cleansing the microphone, paying particular attention to the delicate diaphragm, is crucial to ward off dust buildup that could compromise functionality. To safeguard the microphone from potential harm and extend its lifespan, secure storage in a protective case or pouch is recommended. This practice not only shields the device from external elements but also minimizes the risk of damage, ensuring that the microphone remains in peak condition for an extended duration. Incorporating these maintenance steps becomes a proactive measure in preserving the microphone’s functionality and durability.
Applications of Microphones
Microphones hold pivotal significance across diverse domains, each demanding specific functionalities. Within the studio environment, these devices meticulously capture the intricacies of musical performances, enhancing the creation of top-tier recordings. Podcasters heavily depend on microphones to articulate their voices with precision, fostering a more intimate connection with their audience. In expansive venues, microphones serve as amplifiers, guaranteeing that the voices of performers resonate effectively and reach the farthest corners of the audience, ensuring an immersive and impactful experience for all attendees. The unique applications of microphones underscore their versatility and indispensability across various facets of communication and entertainment.
Benefits of Understanding Microphone Functionality
Gaining a profound insight into the workings of microphones grants users the capability to fine-tune settings, resulting in unparalleled audio quality.

Strategic cooperation between Georg and Güdel Group
Kreuztal/Langenthal, Germany, June 19, 2017 Heinrich Georg Maschinenfabrik and Güdel Group AG concluded a cooperation agreement for the collaborative development of lines for the automatic stacking of transformer cores. GEORG brings in their know-how in the plant engineering field, Güdel the robot technique for the automatic stacking of the laminations. That way, systems are constructed in the future that speed up the production of transformers, reduce manual time and enable a higher production flexibility. Furthermore, the intensive data transfer prepares the ground for industry 4.0 / IoT.
GEORG brings in profound knowledge of the entire line technique in the transformer industry – from the decoiling of the strip from the coil over the cutting-to-length of the strip to the cutting of the laminations and the stacking of the cores. Güdel contributes the robot handling systems and the networking of the individual components among each other.
As there are several GEORG customers who cut ahead and stock laminations which they want to stack to a core with an offline system at a later stage, the focus for the first common projects will be the development of an offline system for the automatic stacking of transformer cores.
The laminations cut by the GEORG line and interim stored are picked up and stacked fully automatically by the Güdel robots. For the positioning, the robots achieve highest accuracies and beyond that accelerate the core stacking process significantly. The direct data transfer from the cutting line to the robot unit makes time-consuming manual processes redundant. By this data coupling, the new systems can be easily integrated into digitally networked environments and thus prepare the ground for industry 4.0 / IoT.
Bernd Peter Schmidt, Managing Director of the transformer business division at GEORG sees considerable benefits for his customers: “By the cooperation of our two companies – who both have an outstanding reputation in their respective field – we will deliver complete systems that make the stacking of the laminations much more effective. We make use of the vast experience and well-proven standard components of Güdel. This means for our customers: innovative and at the same time reliable technology with considerable cost advantages.”
Rocco Montalenti, General Manager Business Unit Technologies at Güdel relies on the market knowledge of GEORG: “For more than 30 years, GEORG manufactures transformer lines and has an impressive market share worldwide. The GEORG employees know the conditions in the transformer industry inside out. By this, we are able to elaborate single-source solutions together that are exactly adapted to the requirements of our common customers.”
The cooperation is in accordance with the philosophy of both companies to offer optimal solutions for smooth transformer production processes.

Images and descriptions of two unannounced Amazon Alexa devices publicly surfaced Wednesday afternoon, providing an inadvertent sneak preview of what was previously reported to be a new wave of smart home devices from the Seattle-based tech giant.
The devices, discovered by the tech site Pocket-lint on Amazon’s UK site, include a new Alexa-powered “Echo Sub” subwoofer that can be used with an Echo or Echo Plus to play room-filling music, or paired with other Echo devices for “rich left/right stereo sound,” according to the description.
In addition, there is a new Amazon Smart Plug that adds voice controls and scheduled on/off functionality to electrical sockets. Although many third-party device makers offer Alexa-enabled smart plugs, the description for this device says it works without a smart home hub, via the Alexa app. Existing plugs are commonly used in conjunction with an Echo speaker or other Alexa device.
CNBC reported earlier this week that Amazon is preparing to release eight new Alexa-powered devices, including a microwave, amplifier and an in-car Alexa device.
We discussed the CNBC report on this week’s episode of our Geared Up podcast, below.


Cyber threats have become far more sophisticated over the years, and will continue to rapidly advance in the age of AI. Thankfully, security solutions also leverage the latest technology to stay one step ahead of malicious activity. Despite the innovations, the greatest risks to IT infrastructure continues to be the human that can compromise an environment.
Technology companies like Cisco create tools that can help security professionals keep their networks safe while mitigating the risks that end users will compromise a network. As a company that’s been around for more than forty years, Cisco looks for ways to improve the quality of their firewalls to account for user interactions, but have also developed tools that can be layered on top of the firewall to create a coordinated, cohesive cyber security strategy.
Developing a robust cyber security posture is critical for success in the modern era. Here are a few of the ways that Cisco can help you create a safer network for your organization:
The Next- Generation Firewall
Every organizational leader knows the importance of a firewall, but Cisco has made it easier for IT professionals to ensure their organization remains secure by creating a dynamic firewall system managed by one of the largest cyber security firms in the world.
Cisco’s Firepower Firewall leverages intelligence from Cisco Talos, a leader in the threat intelligence space. Talos uses IP behavior information pulled from not just your firewall, but a collection of cloud-based intelligence analysed from every Cisco Firepower Firewall in use across the world to determine if network traffic may be malicious. With this intelligence, Talos is able to make proactive decisions about which traffic to allow into an organization’s network. This use of traffic and reputational data enables Talos to protect an entire network of computers from cyber threats and keep them from spreading should an attack succeed.
An AI-Powered Monitoring Tool
While managing IP behavior and blocking potentially malicious software from gaining access to an organization’s network, there’s a component of cyber security that’s more difficult to protect against – human behavior. That’s why Cisco created its Identity Services Engine (ISE).
Cisco’s ISE is a tool that’s designed to recognize patterns in the behavior of employees. Using an AI model built on organizational policies and the behavior of end users, ISE looks at all aspects of a user’s connection (such as credentials, location, time, etc.), and communicates with the firewall to prevent access if it detects a threat to the network. Additionally, ISE can automatically set up a captive web portal for systems joining the network if, for example, there’s an employee laptop that’s out of date and needs to download the latest patches to serve the organization better. That way, your network remains secure while allowing you to restore a company asset to its full utility.
Lastly, ISE has the ability to connect with a wide range of integrations, enabling it to pull in even more information to evaluate a connection. Utilizing all available data points, it can come to the optimal decision when deciding to deny traffic to a user displaying abnormal behavior.
A Flexible Authentication Tool
While a smart firewall and user behavior monitoring engine are sophisticated tools that can keep your organization’s network safe, two-factor authentication (2FA) can help protect end users’ credentials by adding an extra layer of verification for user credentials.
Cisco’s Duo provides that layer of security and the flexibility to integrate into nearly any tech stack. With Duo, users can confirm their identity through phone call, text, PIN, pop-up, or another forms of verification. The tool can also integrate into other platforms, including those outside of the Cisco ecosystem.
Protecting Your Network on the Go
In an era of hybrid and remote work, an organization must account for threats from devices that may not have access to tools that businesses generally do. Enabling an employee to access the business’s network from their personal cell phone or laptop changes the way you have to approach cyber security, and one way to do that is to use Cisco’s Umbrella tool.
The Cisco Umbrella tool is specifically designed to protect end users from visiting sites that could be dangerous. Basically, it filters all your traffic through the network to Talos for review and if something’s identified as malicious, it blocks the end user from accessing the website.
This ensures your network remains secure even if an employee accidentally visits a malicious website or forgets to turn on their VPN.
The Benefits of Using the Cisco Platform
While cyber security has become far more complicated than it used to be, Cisco has created a variety of tools that can be used to streamline your organization’s security operations. Cisco products, when used together across your business’s IT environment, help protect your business by evaluating the entire picture of your organization’s network behavior and minimizing the traffic from potential bad actors.
However, there’s rarely a one-size-fits-all tool that works for every organization. Cisco provides a robust set of tools to keep networks secure, but there are benefits to creating a plan that’s tailored to your organization’s specific needs. This could mean diversifying the kinds of firewalls deployed or utilizing a handful of Cisco products to achieve the end goal of a secure network.
Understanding your needs is the first step to an effective cybersecurity plan. Hammer Tech has helped many organizations weigh their options so they can feel confident in their organization’s security. If you want to ensure you’re getting the best of the best, contact us.
