The IEEE 802.11ad, which is also called DMG (Directional Multi-Gigabit in IEEE 802.11 standard), provides data throughput speeds of up to 8 Gbps with low latency, using the 60 GHz ISM band to achieve the required levels of bandwidth and ensure reduced interference levels. Wi-Fi Alliance has introduced Wi-Fi CERTIFIED WiGig to accelerate the commercial availability of devices, whose MAC/PHY specification aligns exactly with the 802.11ad standard. WiGig complements Wi-Fi CERTIFIED ac and increases network performance, resulting in better use of network resources and rivaling wired connections.

At unlicensed 60 GHz band, each channel for WiGig is 2.16 GHz wide. The 802.11ad PHY supports following three main signals with different modulation:

The OFDM mode is defined in IEEE 802.11ad standard, but no commercial implementation yet.

LDPC encoding with codeword size of 672 bits is applied to DMG SC mode. The table below displays the SC mode modulation and coding (MCS) schemes. MCS 0 is used to identify the DMG control mode.

The figure below shows the SC PPDU format. A SC frame is composed of the Short Training field (STF), the channel estimation field (CE), the Header, SC blocks (BLK) and optional training fields.
