User's Manual

e) Going in the Upstream, the modem output (transmit) upstream is
whatever the CMTS configuration has instructed, which is in the range
of 6.4 to 41.6 MHz.
f) The Subscriber Transmitter (inside the CPE Transceiver) up-converts
this IF channel to the 5.3 GHz band, which goes over the air to the
Access Point Receiver. The RF transmission is scheduled by the
DOCSIS protocol, so that it does not interfere with other modem
transmission on this channel.
g) The Access Point Receiver tuned to 5.3 GHz band, down-converts this
to the upstream channel 6.4 to 41.6 MHz.
h) The CMTS Upstream port detects the 6.4-41.6 MHz upstream signal.
