The IEEE 802.11ax standard, widely known as Wi-Fi 6, has been with us since 2019. Not long after, first wireless devices have been launched by vendors on the global market. But as with every technology, time has to pass before businesses gain the option to choose from a rich portfolio of competitive devices that use […]

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.

Roughly speaking, an administrator will have around 10 interfaces to use to keep the system running. It all takes time. Hence, it is convenient to manage all elements of the system from one place.

I want to thank all readers for their interest in the post and the discussions we had during the past months about 5G health issues. There was a high number of supporting comments and requests for clarification, but also quite a few critical comments to both of my published posts (What’s wrong with the “studies” and 5G health […]

You may wonder why I’m writing about Dual Connectivity. After all, it comes from LTE in Rel-12, when we are currently within the Rel-16/17 timeframe. The reason for this is that the DC from LTE is treated as a baseline. The enhanced version is incorporated within 5G as one of the main features to allow the so-called Multi-RAT DC (MR-DC). If we look from a broader perspective, we have a multitude of use cases for DC, including LTE-DC, NR-DC, LTE-NR-DC, NR-LTE-DC, LWA. Therefore, this post aims at shedding light on the different aspects of DC, being the legacy feature, which can be extrapolated towards the current situation. 

This is a short overview of Smart Cities and company’s IoT product deployment case study, which is based on the article “Adoption of Smart Cities with a Practical Smart Building Implementation“ [1] by Marcin Dryjański, Mateusz Buczkowski, Youssouf Ould-Cheikh-Mouhamedou, and Adrian Kliks which is a magazine article in IEEE Internet of Things Magazine. Abstract [1] Smart […]

We’ve been bringing the tech trends to the readers of our blog, by continuing to write on certain topics (like 5G, SD-WAN, Wi-Fi networking). As a summary from 2019, we have compiled here a list of the 5 most popular posts from our website.

3GPP Release 17 is about to be started soon. It will mostly be about enhancing and “further” enhancing 5G features in different areas. Regarding the overall timeline, the content of Rel-17 is to be defined in Q4 2019, and the aim is to froze it in Q3 2021.

It was a very interesting event, despite being small in the number of participants. We could listen about the current 5G status from different angles including perspectives from vendors, solution providers, verticals, standardization, governments and research. The one I was missing though, was the MNO “reality check”. I believe that the industry reached now the time, when we are slightly moving beyond the 5G hype and switch from “5G is the answer – now, what was the question” to “who pays for the new infrastructure and spectrum”, being the reality check.

This year’s CROWNCOM conference was held on 11-12 June, in our hometown – Poznan, Poland – discussing the following topics: ML for spectrum management, spectrum sensing, REM, spectrum sharing and management, spectrum assessment and valuation, HetNet and hybrid networking, current 5G standardization and future topics for 3GPP, RAN slicing, business models innovation, which are summarized in this post.
