Forward and reverse channel
Short answer
The forward channel (downlink) transmits from base station to mobile; the reverse channel (uplink) transmits from mobile to base station. Both carry traffic and control information.
Define forward and reverse channel.
- Forward channel (downlink): the radio channel used to carry information from the base station to the mobile user. Example: in GSM-900 the forward band is 935–960 MHz.
- Reverse channel (uplink): the radio channel used to carry information from the mobile user to the base station. Example: in GSM-900 the reverse band is 890–915 MHz.
Both directions contain voice (traffic) channels and control channels. The control channels (forward control channel and reverse control channel) carry call set-up, paging and access messages.
