When it comes to making the most out of a radio channel, 5G NR goes to even greater lengths than LTE. There are lots and lots of mechanisms for the base station and the UE to analyze current channel conditions and, based on the results, optimize their transmitter and receiver settings accordingly. Quite a number … Continue reading 5G – How To Control Beam Forming – Channel Measurements
So here we are in the fall of 2019. 5G networks have started around the globe and pretty much all of them use high-band spectrum at 3.5 GHz (band n78). US operators are experimenting with 2.5 GHz and mmWave spectrum in combination with an LTE anchor cell. The anchor cell is usually either at 1.8 … Continue reading How To Get Nationwide 5G Coverage and a 5G Core Network
Over the past weeks I’ve noticed a few articles, posts and videos on the net that were looking at first 5G deployments in the wild and were commenting on the seemingly limited range of the 3.5 GHz band that is used for 5G NR. Some people noted that only 200m from the base station they … Continue reading The Range of 5G Band n78
The spectrum situation for mobile services in the US has always been different from much of the rest of the world. More often than not, US network operators have to cobble together 5 and 10 MHz chunks of spectrum for their customers while in the rest of the world, aggregating 20 MHz channels is the … Continue reading The US Will Get 3.5 GHz Spectrum for 5G – But Not Much
Sprint has recently deployed 5G in the Chicago area and has put an impressive coverage map online. Needless to say that I had to go to a Sprint store to see if I could get a demo of their 5G network. My expectations where high because they did advertise 5G in their windows.
For some time I’ve been seriously considering to come up with some sort of filter that would just hide news articles with ‘5G’ in the title. The vast majority just talk about myths not founded in this reality or were just pure marketing hype for some esoteric function. It seems I am not the only … Continue reading 5G Myths And First Speed Test Results From the US
It’s early days in 5G deployment and while Vodafone, as far as I know, has not yet launched their 5G network in the UK they have already published a coverage map so one can get an impression of where 5G will be available once they open up their network.
In the previous two posts on 5G NR massive MIMO, a.k.a. beam forming, I’ve gone into the basic principles of what it can be used for in practice and how antennas for beam forming will look like. Great background information from Keysight and Ericsson respectively. The next question I then had was how mobile device … Continue reading 5G: How To Control Beamforming
So far I’ve always made a quick and approximate calculation when somebody asked me what the theoretical peak data rate of 5G NR would be for a given bandwidth. But there is a more scientific way to do this as 3GPP has put a formula together to include all relevant factors in the calculation. Using … Continue reading 5G NR Throughput Calculator
Network operators in a lot of countries around the world are getting ready at the moment to launch first 5G networks in the 3.x GHz spectrum (i.e. 3GPP band n78). One of the particularly interesting things about this band is that its made for TDD operation and not FDD as most operators are used to. … Continue reading 5G NR in 3.x GHz – Up- and Downlink Configuration
