Green improvements of IEEE 802.11 directional multi-gigabit physical layer specifications

In the context of green communications, millimeter wave bands are investigated to ensure mobile access and backhauling. Such transmissions can be performed with the IEEE 802.11 Directional Multi-Gigabit (DMG) modes, designed for very high throughput in the 60 GHz band. However, the DMG Orthogonal Frequency-Division Multiplexing (OFDM) physical (PHY) layer specifications corresponding to the highest data rates are not energy-efficient. Therefore, in this article, we propose easily implementable green improvements for IEEE 802.11 DMG OFDM PHY: a change of error correcting code and a new modulation and coding scheme. Binary error rate performance evaluations are made to show the green benefits of our improvements.
