廣播控制通道-
If the gprs network is to be built over the gsm 900 network, bcch carriers should be chosen as the gprs wireless channels. in this case, seven slots at most can be used as the traffic channels
若在gsm900上建設gprs ，應選擇bcch載頻作為gprs無線通道，此時最多有7個時隙可以作為業務通道。 -
In the gsm 1800 system, the 4 x 3 frequency allocation mode can meet the need, while in the gsm 900 network, the usual practice is that for the bcch carriers, the 4 x 3 reuse mode is used and for other channels, the 3 x 3 frequency hopping reuse mode is used
在gsm1800的系統中， 4 3的頻率分配方式能滿足需要，而在gsm900中，通常bcch載頻採用4 3復用方式，其它通道採用3 3跳頻復用方式。
