Radio Unit Bandwidth
The available Radio Unit data bandwidth is defined by the Radio Unit
’s RF bandwidth and
modulation settings, some examples are outlined in the following table.
Remaining bandwidth not utilised by the FWA interface may be utilised by other services
supported by the Radio Units such as Ethernet data.
Net Available Radio Unit Bandwidth (bps)
16 QAM
64 QAM
25 kHz
129000
194000
12.5 kHz
65000
97000
Note: For a complete list please refer to the ’About that
MiMOMax Data Rate
’ whitepaper.
As an example Radio Units set to 25 kHz / 16 QAM connected to FWA interfaces with the
CTRL selector set to 8 and a UART rate of 9600, would provide the following.
A single static audio channel.
9600 bps UART data.
Up to 55400 bps of Ethernet data.
A single additional dynamic audio channel limiting Ethernet data to 23400 bps when
active.
Alternatively if UART data was not utilised then the following would apply.
A single static audio channel.
Up to 65000 bps of Ethernet data.
Two additional dynamic audio channels limiting Ethernet data to 33000 bps when one is
active and 1000 bps when both are active.
