Abstract: A system and method are provided to facilitate establishing WiGig communications links between WiGig-enabled wireless devices and WiGig PBSS Control Points and Access Points (PCP/AP). The PCP/AP transmits beacons that are intended to assist the wireless devices in locating the PCP/AP. Based on the directional nature of WiGig communications, the beacons are transmitted directionally in a number of sectors in multiple directions simultaneously or in sequence. When devices, such as wireless devices, attempting to connect via a PCP/AP, are positioned very close to the PCP/AP, the devices may be incapable of receiving the transmitted beacons because the low noise amplifier (LNA) located in the individual wireless device receiver may become saturated. The disclosed systems and methods broadcast the beacons at lower power according to different schemes at certain intervals to avoid saturating the LNAs.

Abstract: An extended range preamble is disclosed, for transmission between extended range 802.11n devices. The extended range preamble consists of a high-throughput signal field, in which a modulation coding scheme rate and payload length are specified by the transmitting device. The extended range preamble also includes an expanded preamble, which is adjacent to the high-throughput signal field, and is not understood by non-extended range devices. The modulation coding scheme rate is specified as either one of the rates supported in non-extended range 802.11 devices or as a reserved modulation coding scheme not understood by the non-extended range devices. In either circumstance, the non-extended range device respects the preamble, and thus does not itself attempt a transmission during processing of the preamble.
