Chapter 4 - Operation and Administration Sector Menu
BreezeMAX Extreme 177 System Manual
In Single sector Dual BS Operation Mode, the sector operates using two adjacent
channels. Therefore the selection is based on the statistics gathered from the two
adjacent channels. Also, once a degradation is detected on one of the channels,
instead of stopping the operation in both channels the DCS first verifies if the
other adjacent channel (on the other side of the “good” channel) has better
conditions then the “bad” channel. The verification is performed using the average
NI of the current channel, and the NI measurements of the new channel. If the
channel has better conditions then this channel is selected. This process ensures
that service to MSs served by the “good” channel is not interrupted. If not, then
the operation of both channels is stopped and the new channels selection
mechanism is triggered.
