1. A receiver coupled to a plurality of Wi-Fi receiver chains, the receiver comprising:
a controller configured to:
collect signal quality parameters from each of the plurality of Wi-Fi receiver chains, wherein each of the signal quality parameters comprises a signal quality parameter level;
control a state of each of the plurality of receiver chains, by comparing the signal quality parameter level of the receiver chain with a predetermined signal quality parameter threshold; and
selectively turn off, receiver chains that are in an “ON” state and have signal quality parameter levels that are lower than those of at least some of the other receiver chains among the plurality of receiver chains such that a total number of receiver chains that remain in an “ON” state is equal or less than a predetermined number, wherein the controlling of the state of each of the plurality of receiver chains comprises:
setting an “ON” state for receiver chains having measured signal quality parameter levels that exceed a predetermined signal quality parameter threshold.
