WiGig, a complement to Wi-Fi?

The WiGig sytem for “Gigabit Wireless”, is a local wireless communication system of Wi-Fi type developed by the Israeli company Wilocity. The project which was launched in 2009 by the Wireless Gigabit Alliance and submitted to the WiFi Alliance in 2013, the 802.11ad reference, is probably able to be marketed in 2015.

The goal is to create interconnecting wireless devices for use in the office and for entertainment at home, between computers, tablets, smartphones, projectors and screens, to completely remove the wiring. The need to constantly connected devices and ready to the data transfer is more and more obvious. The WiGig specification enables devices to communicate wirelessly at multi-gigabit speeds. It allows wireless data to ensure high performance display and audio applications in wireless LAN. The 60 GHz signal can not penetrate walls, but in general, it can spread by reflections off walls, ceilings, floors and objects using the WiGig integrated beam forming managed by the system. The WiGig protocol would be associated with a new version of the USB wireless using the existing USB 2.0 and 3.0 drivers.

With the WiGig operating on frequency bands 2, 4 and 5 of 60 GHz, it is possible to achieve downstream data rates from about 1 to 7 Gbps for very short distancesne having no obstacles, for example, about ten meters without crossing the wall. This low energy technology has the advantage of being able to provide instant access to a Cloud, meeting the requirements of downloading multimedia content, and changing the paradigm of current cellular networks. It would be well suited in the context of applications connected objects, or 4K video streaming for the hospitality industry. It could also suit the MU-MIMO (Multi-User Multiple Input Multiple Output) method that improves two to three times the capacity of the network while optimizing how each device is used in connection.

According to Juniper Research, 60% of mobile traffic would use Wi-Fi networks in 2017, especially in areas of high concentration of mobile users. Within the same 60 GHz band, WiGig will compete with WirelessHD for certain applications. See also www.wilocity.com/  www.linformaticien.com/
