About 5G

I have written about the 5G positioning techniques not that long back on this blog here and on connectivity technology blog here. With Release-16 now ready for deployment, Huawei has already announced world’s first in 5G Indoor Positioning. Their announcement said: China Mobile Suzhou and Huawei reached a new milestone with the verification of the

In my last post I described how NG RAN resources can be divided into network slices.  Now I would like to show how these network slices and the traffic they carry can be identified.  The key to this is a parameter from the NG Application Protocol (NGAP) called the Single Network Slice Selection Assistance Information

Back in Feb 2020, ETSI announced the launch of a new group dedicated to specifying the fifth generation of Fixed Network (ETSI ISG F5G). The press release said: We are entering an exciting new era of communications, and fixed networks play an essential role in that evolution alongside and in cooperation with mobile networks. Building

I have been asked to explain in a nutshell how network slicing works in NG RAN. The most important facts you will find in the infographic below. A network slice is virtual part of a network that offers full end-to-end connectivity for particular services and – optionally – for tenants. A tenant is a 3rd-party

Last year we announced the launch of Free 5G Training. It was successful beyond our imagination. While we have just over 1,300 Twitter followers, on LinkedIn, we have over 30,000. The 5G for Absolute Beginners Udemy course already has over 6,000 students. This was a good enough motivation for us to launch a 6G equivalent

Although a couple of SON mobility robustness features have been introduced in LTE radio networks it is still a common problem in some network areas that a high number of handover failures leads to higher drop rates and large numbers of RRC Re-Establishments. Often these problems occur due to quickly changing radio conditions in the

It’s been just over a year since I wrote a detailed post on what I called ‘5G and Fixed-Mobile Convergence (FMC)’. The technical term being used in the industry for this feature is Wireless Wireline Convergence (WWC).  BBF (@Broadband_Forum) has published 3 new standards to accelerate global 5G adoption – https://t.co/ufoHRfK3BE – Wireless Wireline Convergence (#WWC)
