IEEE WLAN 802.11-ad is 802.11 family of standard for WLAN ( Wireless Local Area Networks) It has following features compare to its previous WLAN standard devices operating in 2.4GHz and 5 GHz bands.

WiGig is the name given by IEEE engineers and Wireless Gigabit Alliance for marketing reasons for products as per IEEE 802.11ad standard. This standard based devices operates in 60 GHz band and hence it is often referred as microwave wifi.

This standard is developed for very high speed throughput at shorter distances. This is evident as path loss is higher at this high microwave frequency. There are 4 channels supported in this WiGig standard. They are 58.32 GHz, 60.48 GHz, 62.64 GHz and 64.80 GHz. All the channels support 2.16 GHz wide bandwidth to provide higher data rate. Different regions support different radio frequency allocations for WiGig based devices.

Various Physical layer configurations are supported in IEEE 802.11ad standard. Hence various modulation and coding techniques are available based on channels of use. The physical layer configurations are control PHY, single carrier PHY, Low power single carrier PHY and OFDM PHY. The typical modulation techniques employed here are π/2 DBPSK, π/2 BPSK, π/2 QPSK, π/2 16QAM, OFDM-SQPSK etc. LDPC technique is used as forward error correction technique.
