Gsm vendors and operators in Nigeria

Transceiver (trx) and Dual Radio Unit (DRU)

In a typical 2G GSM network, the DRU is the heart. It contains Transceiver for transmitting and receiving signals. Feeder cable from sectorial antennas are terminated on the Transceivers.

I'm writing this based on Ericson configuration or plan. There are different vendor in the market which I will be writing on,  in a different post. A basic knowledge of the E1 as discussed in our previous article will be of help.
By Ericson plan a single 2G cabinet can on take 6 DRUs supporting 12 Trx though in Theory one E1 support 15 Transceiver.

If one E1 is equivalent to 15trx and one Transceiver is equivalent to 8 time slots.  Therefore 15Trx will be equivalent to 120 time slots, this achieved by multiply 15 by 8. This is from the angle of the E1 link. Going by the DRU technology a cabinet can only contain 12 trx for a 2 x 2  x 2 configuration.

Now if we multiply 12 transceivers by 8 time slot we will get a total of 106 time slots or subscribers. This is the subscriber density for a typical DRU base configuration. All Ericsson configurations follow even number pattern.

Other vendors you will see in the Nigerian telecommonication market are:
1. Hauwe
2. Alcatel
3. Motorola-simens
Telecommunication in Nigeria is based on operators and vendors. The vendors provide the equipments and the operators are license to operate. These operators are MTN, 9Mobile, Glo, Airtel and Mtel. Mtel one of the operators own by the Nigerian Government ( the only Government operator )refused to grow after selling subscriber identity module (SIM). For over ten years now this license has been without use. Many have been pulled out of their jobs since then and all attempt to sell it to a private operator yielded no result. We will appreciate any contribution reguiding the different attempts to sell Mtel through the comment box.
