T Mobile says that the modernization of its Czech Republic GSM network will be entering its second, final stage this month. Within the project, which began in October 2008, all of the 4,540 base transceiver stations (BTS) are being gradually replaced with Huawei equipment to offer nationwide EDGE coverage.

However, T-Mobile is not investing only in its GSM network. In addition to 2G modernization, T-Mobile is making intensive preparations for new technologies such as new-generation mobile networks and IP-based telephone services. The main building block is the "Dark Fibre" project, i.e. construction of a network containing more than 6,000 km of fiber-optic lines which will offer capacity of up to 60x10 Gbitps, thus providing sufficient space for transmission of large data volumes.

The most important project from the customer's point of view - GSM network modernization - has been completed in Moravia, Silesia and in South and West Bohemia. By June 2010, when the modernization process will be completed, technicians will have replaced technology in North Bohemia, Prague and Central and East Bohemia.

The shortest time required for replacement of a base station was 24 seconds. The longest replacement time recorded was eight hours during the replacement of a base station at the Brno fairgrounds, as this base station's technology contained a total of 20 sectors and was located in 13 separate cabinets, while the technology of a standard base station can fit in one or, at most, two cabinets. The average replacement time is 10 to 20 minutes for indoor BTSes and 2 hours for outdoor BTSes.

Every day five to seven teams are simultaneously in the field, working on the replacements, and their work is coordinated by T-Mobile experts and Huawei technicians from the Network Maintenance Centre in Prague.
