Access Request
Channel access scheme where the base stations 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.
This mode is a general purpose access method for high and low
load networks.
Listen Before Send
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.
The default setting is Access Request.
