In the previous 3 parts of this series, I’ve had a look at the superb LTE/5G network coverage that has been installed in the tube in central London in 2024. One main question that had to remain unanswered at the time was how much capacity has actually been put into place. On one end of … Continue reading London Tube – LTE/NR 3.5 GHz Deployment – Part 4
Another day, another little trace session in the London tube when coming home from a event in the evening at 9 pm. In Part 2 of this series I’ve taken a look at one network operator’s LTE/5G coverage on London’s Central underground line and came away quite impressed. 5G NR n78 on the platforms with … Continue reading London Tube – LTE/NR 3.5 GHz Deployment – Part 3
When I was recently in London I was delighted to see that LTE/5G network coverage has finally come to first parts of the London tube. I didn’t have a lot of time or space to get my tracing equipment out, but I could nevertheless get a glimpse on some of the basic parameters on my … Continue reading London Tube – LTE/NR 3.5 GHz Deployment – Part 2
For the last 20 years, I’ve been wondering when mobile network coverage would finally come to the London tube. Together with Berlin, London was/is one of the last remaining major cities in Europe I have visited in recent years without decent mobile network coverage in underground public transportation. But it seems that the people who … Continue reading London Tube – LTE/NR 3.5 GHz Deployment – Part 1
I have just arrived in one of the few cities in this part of the world in which the metro (underground, tube, whatever you call it) is not covered by mobile networks. It's a sad state but maybe the mobile gaming industry is rejoicing as I noticed a lot of people this time using their … Continue reading Do Londoners Spend More Money on Mobile Gaming?
It’s the time of the year again to reflect on what has happened in the last 12 months and looking back, I’m happy to say that it has been an eventful year again. So let’s jump right into it.
In the past 3 posts I’ve had a high level look at the superb new London tube network coverage. With data rates of 500 Mbps without any special setup, it is nothing short of breathtaking. Unfortunately, the same can’t be said for other busy places in London.
Next to the London tube, New York's underground transportation system is one of the few places I have noticed over the years that still lack wireless coverage on a broad scale. It looks like things are changing though as I was positively surprised to have coverage in one of New York's metro stations recently. Have … Continue reading New York Metro Wireless Coverage – First Stations Connected At Last
An interesting parameter in the Internet world is how much a carrier has to pay to send a certain amount of data to another part of the Internet. The currency for that is peak bandwidth requirement, i.e. the peak MBit/s going through an interface (at the 95% percentile). So if a carrier has 20 GBit/s … Continue reading IP Transit Prices Continue To Fall
Wow, a year has passed since I last had the honor to host the Carnival of the Mobilists on my site. Last time I got the heads up for hosting the Carnival via eMail while sitting in a taxi on the way from Lisbon airport to the city center. This time around, Rome’s the place, … Continue reading The Carnival Of The Mobilists #74
