1. A method for configuring sectors of an in-building wireless communication network, the method comprising:

transitioning at least one in-building radio transceiver from a first sector to a second sector, the transitioning step being performed during a transition period in which the at least one radio transceiver transmits a weighted sum of a first data signal and a second data signal, and at a start of the transition period the signal strength of the first data signal is greater than the signal strength of the second data signal, the first data signal being associated with the first sector and the second data signal being associated with the second sector, the weighted sum varying such that, during the transition period, a signal strength of the first data signal decreases and a signal strength of the second data signal increases; the transitioning further including,

applying a first weight to the first data signal, the first weight gradually decreasing from a first value to a second value during the transition period,

applying a second weight to the second data signal, the second weight gradually increasing from the second value to the first value during the transition period,

combining the weighted first and second data signals to generate the weighted sum of the first data signal and the second data signal, and

transmitting the weighted sum of the first data signal and the second data signal to the at least one radio transceiver.
