Description: GSM Channels
Physical Channels
Associated with frequency bands, time slots, codes
Physical channels transfer bits from one network element to another
Logical Channels
Distinguished by the nature of carried information and the way to assemble bits into data units
Three types
one-to-one: traffic channels between a BTS and a MS
one-to-many: synchronization signals from BTS to MSs in a cell
many-to-one: from MSs to the same BTS
