You will most likely not notice the antennas of the T-Mobile base station (BTS) at Londýnská 59 in Prague. The roof of the building on which it is located is not very visible from the surrounding streets; there are actually quite a few places from which you can catch a glimpse of it. It must be admitted that the antennas look like almost all the others and from a technological point of view they are no miracle.
You will be much more interested in the fact that the Cell ID of this three-sector base station is 1, 2, 3 (10001, 10002, 10003 for 1800 Mhz) – it is the imaginary BTS number one in the T-Mobile network (former Paegas). It was built as one of the first five that began transmitting the Paegas network signal. It was originally intended to cover a large area; today its performance has been reduced and, due to the greater capacity of the network in the center, it also began transmitting at the 1800 Mhz frequency.
This is, of course, a base station located at the headquarters of RadioMobil, our second largest mobile operator.
The base station itself, i.e. the box that handles communication between mobiles, BTS and the rest of the network, is located on the top floors of the building. The same room also houses part of the switchboard for RadioMobil's internal telephone network (you can see it in the photos).
Because the roof of the building on Londýnská Street is one of the highest in the center of Prague, RadioMobil also uses it as a communication node for microwave and laser connections. The area covered by the BTS we are describing is not very large - the density of traffic in this area is so high that base stations must cover a rather small area and there must be more of them. In fact, there is one microcell right in the courtyard inside the building; you can find another one above the T-Mobile store on the street. And if you go even further into the center from here, you will find a RadioMobil microcell on almost every corner - literally.
