1. A system operative to create a WiFi access zone, comprising:
an orthogonal frequency-division multiplexing (OFDM) WiFi access point configured to transmit OFDM WiFi signals; and
at least two hybrid converters communicatively connected to the OFDM WiFi access point, in which each of the hybrid converters, and simultaneously with the other hybrid converters, is configured to receive the OFDM WiFi signals from the OFDM WiFi access point and re-transmit, from at least one antenna associated with each hybrid converter, the OFDM WiFi signals wirelessly;
wherein the OFDM WiFi signals re-transmitted wirelessly, by the at least two hybrid converters simultaneously, are operative to create, using multiple sub-carriers in the OFDM WiFi signals, an access field that is perceived, simultaneously, by at least two OFDM WiFi client devices that are not co-located, as one continuous OFDM WiFi access channel, and without compensating said re-transmissions specifically for any of the at least two OFDM WiFi client devices,
wherein:
the at least two hybrid converters are not co-located, and
a net effect for the multiple sub-carriers, of the at least two separate re-transmissions, is a boost in overall power received by each of the at least two OFDM WiFi client devices.
