This article provides current status of the WiGig (802.11ad) standard including a brief summary of the standard, a list of challenges the standard is facing and recently announced news.
WiGig (802.11ad) standard summary:
The WiGig (802.11ad) standard operates on the 60GHz frequency band with a channel width of 2.16GHz. The physical transmission rate of the standard is 4.6 Gigabits per second (Gbps) but the actual throughput of the receiving devices from testing groups have been reported around 2.5 Gbps. This technology features higher throughput and lower latency than any other Wi-Fi standard in the market today. Another prominent feature is narrow beam forming technology which is a method of steering the transmission signals to the direction of the receiving device to minimize interference.
Despite its advantages, the 802.11ad standard has clear limitations from operating on the higher 60GHz frequency band. Such high frequency signals cannot penetrate through walls and coverage distance is less than 100 feet (33 meters). Due to these limitations, use of 802.11ad is confined to open public areas (such as airports) or only inside a living room in a house and is often referred to as the complementary standard to the 802.11ac.
List of challenges faced by the WiGig standard:
Currently there are four main challenges that are limiting wider adoption of the standard. Below are the description of these four challenges:
