Methods and systems are provided for implementing low-cost Internet-base-station (LCIB) radio-frequency (RF) adaptation using stationary transceivers. In an embodiment, an LCIB emits a pilot beacon having an adjustable transmission-power level. The LCIB repeatedly wirelessly sends transmissions for receipt by each transceiver in a set of one or more stationary transceivers while increasing the power level at which the transmissions are sent. The transceivers are arranged to wirelessly send acknowledgements to the LCIB upon successful receipt of the transmissions. The LCIB receives at least one acknowledgement from a subset of the transceivers, and responsively sets the pilot-beacon transmission-power level equal to an operating value, which the LCIB selects based at least in part on a minimum transmission-sending power level needed to receive an acknowledgement from each transceiver in the subset.
