The 802.11ax brings important features, focusing on network capacity, latency and range. High data rates are still in the picture, but rather in the background. Introducing OFDMA and using MU-MIMO allows AP to schedule data for multiple users simultaneously. This way, latency can be greatly decreased. With the new colors of the channels, frequencies can be spatially reused.

Many people wonder why good design and implementation of corporate LAN and Edge features is necessary. There are many answers to this simple question and among them, we require a good network to be least vulnerable to unwanted intrusions along with it to be able to support all our requirements. We have compiled a list that you […]

What is Wi-Fi 6 (IEEE802.11ax)? How does it compare to Wi-Fi 5 (IEEE802.11ac)? Will older phones connect to Wi-Fi 6? The post combines the most frequently asked questions about Wi-Fi 6.

The AP schedules the transmission according to the actual needs, and nobody wastes time on waiting and on collision. So, we end-up having the system that: is more robust towards low latency services; is more spectrally efficient; allows for actually use some QoS profiles; and coordinates the use of spectrum.

The photon energy of electromagnetic radiation in the microwave spectrum, is by at least 5 orders of magnitude too low to cause any harm in living cells. The only possible impact is a heating effect, but the energy applied by a mobile phone is at least 4 orders of magnitude lower than that used by microwave ovens and can heat human tissues by less than half a degree. The situation around studies of health risks connected to mobile phone usage is discussed. Serious studies show that mobile network and mobile phone usage have no adverse effects on health.

Each time a tower for a cellular network is built or planned to be built in a city or near a rural settlement, there is a new discussion about health issues of mobile phone or network radiation. It is about time to put things back into perspective. I’d like to deal with the reality of mobile network radiation in this post.

2018 was a very interesting year for us and technology. We introduced our IoT product “Souly”. 5G entered the normative work in standardization and released the first “version” of 5G. Wi-Fi introduced new security schemes and changed nomenclature. The networking world shifted towards SDN/SD-WAN solutions.

Introduction to Wi-Fi Security Distributing data using wireless medium means that anyone can capture the signal. There is no boundary, like in case of cable communication, which prevents unwanted access. This means we must take other security measures. In this blogpost we will review current algorithms providing Wi-Fi security and we will take a sneak […]

Introduction First Wi-Fi networks appeared in late 90s and many of us use them ever since. During these years we could observe significant increase of throughput, but what is important, it is not only due to the ISP providing better link. Wi-Fi standard also evolved to keep up with the higher throughputs. If there will […]

Introduction Communication between devices is often discussed on link level, which means that the focus is on how two end points exchange information: what is the protocol, waveform, timing in sending messages etc. This however, does not take into account that there are other devices wanting to use the medium. Using the same medium by […]
