Operating at 60 GHz, WiGig is a near perfect solution to keeping signals in check. Propagation characteristics at that frequency mean they stay very close to the core. That means interference, both to and from surrounding WiGig networks becomes less of an issue. But that also means that they will require more power if wider area coverage is desired. However, implementing directional capabilities can offset that short range omnidirectional property.
What makes WiGig so attractive is that its channels have a wider bandwidth, allowing the transmission of multi-gigabit data with fast per-second speeds. That coupled with low latency and beamforming means WiGig devices can achieve data rates of up to 8 Gbps for typical 10 meter applications. This is an attractive solution for high-bandwidth apps, such as transferring high definition media files to nearby mobile devices, drastically reducing download times.
That particular metric has a lot of potential applications. If WiGig is adopted among a diverse set of devices, such as handsets, tablets, access points, laptops, game consoles and even metro backhaul infrastructure equipment, a lot of bandwidth will become available to handle local and edge demands.
WiGig has a lot of potential, but also some challenges. Even with focused transmissions, power, propagation, poor obstruction penetration and environmental sensitivity all need to be better understood to make WiGig a truly 5G and internet of anything technology.
