There are different kind of networks.
GSM/GPRS works on a cellular network, every "celule" can add up to 7 callers at the same time (the 8th cellule is reserved for data). When one or more of the seven arn't used, they can also be used for data. So the connection between the BTS antenna and the cellphone are direct. The antenna transmits to an HLR and that transmits on one of the centrales of the opérator.
3G/UMTS/HSDPA work on UMTS antennas. Here the transmition is in circels (frequenties) almost like a radio :) Except that one frequentie can only be used once atthe same time..

You cannot use a T Mobile phone on Cricket network. T Mobile is a GSM carrier while Cricket is a CDMA/iDen carrier.
