1. A system comprising:
- a plurality of co-located access points (APs) operative in accordance with an IEEE 802.11 standard;
a plurality of preamble detection units associated with the respective plurality of co-located APs, each preamble detection unit configured to detect a transmission of a preamble in accordance of the IEEE 802.11 standard, by at least one of the other co-located APs;
a plurality of attenuators associated with the respective plurality of co-located APs, each attenuator configured to attenuate a signal received by its associated AP upon detection by the preamble detection unit of a preamble transmitted by another of the co-located APs; and
at least one blanking pulse generator configured to generate a blanking pulse having an amplitude selected such that it desensitizes at least one receiver in at least one of the co-located APs throughout a duration of the preamble as detected by the preamble detection unit.

7. A method comprising:
-
transmitting at least one transmit signal via at least one of a plurality of co-located access points (APs) operative in accordance with an IEEE 802.11 standard; detecting transmission of a preamble in accordance of the IEEE 802.11 standard, by at least one of the APs co-located with the transmitting AP; and attenuating a signal received by at least one of the non-transmitting plurality of co-located APs upon said detection of transmission of the preamble by the transmitting AP, wherein the attenuation is achieved by generating a blanking pulse having an amplitude selected such that it desensitizes at least one receiver in at least one of the co-located APs throughout a duration of the preamble as detected by the preamble detection unit. - View Dependent Claims (8, 9, 10, 11)

12. A non-transitory computer readable storage medium product having stored thereon instructions which when executed cause a processor to:
-
control transmission of at least one transmit signal via at least one of a plurality of co-located access points (APs) operative in accordance with an IEEE 802.11 standard; detect transmission of a preamble in accordance of the IEEE 802.11 standard, by at least one of the APs co-located with the transmitting AP; and cause attenuation of a signal received by at least one of the non-transmitting plurality of co-located APs upon said detection of transmission of the preamble by the transmitting AP, wherein the attenuation is achieved by generating a blanking pulse having an amplitude selected such that it desensitizes at least one receiver in at least one of the co-located APs throughout a duration of the preamble as detected by the preamble detection unit. - View Dependent Claims (13, 14, 15, 16)
