If a cell looking in a direction, lives a population of 1000 people. so how can i calculate the number of TRX that I am going to use in this cell. 26th July 2006 at 17:36 #45455 atifGuest well for trx u must know below things 1) GOS 2) number of channels 3) Erlang 26th July 2006 at 21:37 #45456 PixGuest 1000 people. 70% market penetration = 700 subscribers 25 mErl per person (at busy hour) 700 * 25 = 17.5 Erlangs for this “1000 ppl” area. 17.5 erlang can be handled by 4 TRX. (4 TRX can handle up to 21 erlangs) That’s just approximation : you have to know your penetration rate and the BH subscriber average traffic. 27th July 2006 at 19:13 #45457 HuNiGuest Thanx Pix How did you get 25 mErl per person (at busy hour) Thanx huni 27th July 2006 at 21:38 #45458 PixGuest Huni, 25mErl / person is an average for countries with a high mobile penetration and a high mobile usage. Average should be between 18mErl and 25mErl. Which country are you in ? 29th July 2006 at 13:07 #45459 HuNiGuest Thanx Pix I am in Maldives. Can you please tell how I can get Erlang table.
