Access Request
Channel access scheme where the base station controls the

occupied. This mode is a general purpose access method for high
and low load networks.
Access Request (full
duplex)
Used on a network with full duplex base station hardware and half
duplex repeaters / remotes.
A full duplex version of Access Request channel access scheme
where the base station controls the communication on the
channel. Remotes ask for access to the channel, and the base
station grants access if the channel is not occupied. The base
station can send traffic during remote transmit, exploiting the base
station full duplex capabilities.
Listen Before Send
without
Acknowledgement
Channel access scheme where network elements listen to ensure
the channel is clear, before trying to access the channel. This
mode is optimised for low load networks and repeated networks.
Acknowledgements are disabled.
