Claim of US Patent No. 9,220,033

1. A method of operating a wireless base station comprising:
transmitting a first pilot signal at a first pilot frequency centered in a frequency band;
wirelessly receiving first user data using a first filter configuration to pass energy within the frequency band;
detecting a network condition;
in response to detecting the network condition, terminating the transmission of the first pilot signal, transmitting a second
pilot signal at a second pilot frequency centered in a first half of the frequency band, transmitting a third pilot signal
at a third pilot frequency centered in a second half of the frequency band;

wirelessly receiving second user data using a second filter configuration to pass second energy within the first half of the
frequency band; and

wirelessly receiving third user data using a third filter configuration to pass third energy within the second half of the
frequency band.
