Standards Report
Edward Au

The first few widely accepted amendments to IEEE 802.11 wireless networking specifications— namely IEEE 802.11a, IEEE 802.11b, and IEEE 802.11g—featured relatively low spectral efficiencies and data rates.  Driven by technological advances in signal processing and communications theory, sustained improvement in spectral efficiency, coverage, and quality of service has been achieved in IEEE 802.11n and IEEE 802.11ac. 

In particular, progressive system improvement is achieved by the successive introduction of novel techniques, including orthogonal frequency division multiplexing (OFDM) and multiple-input, multiple-output (MIMO) antenna techniques. 

Some advanced transmission techniques, especially multiuser MIMO (MU-MIMO) and transmit beamforming, have also helped to boost the performance of Wi-Fi to gigabit-per-second speed, and they have led to the current state of the art, namely IEEE 802.11ac in 2.4- and 5-GHz bands, and IEEE 802.11ad in the 60-GHz frequency band.

In my first Standards column, which will appear in the June 2016 issue of the IEEE Vehicular Technology Magazine, I will share with you a few interesting and exciting projects related to both the physical (PHY) layer and the media access (MAC) layer of wireless local area networks (AN), which are developed in IEEE 802.11 Working Group under the management of the IEEE802 LAN/MAN Standards Committee, including:
