IEEE 802 and 3GPP are working together more on coexistence of Licensed Authorized Access (LAA) and Wi-Fi. Since November, each group has made a presentation to the other. There’s been an exchange of liaison statements, the latest on March 18 when IEEE 802 sent 3GPP two statements containing several requests and recommendations.
At its February 20 meeting, the FCC will likely adopt a Notice of Proposed Rulemaking as a first step toward increasing the amount of spectrum available in the 5 GHz band for unlicensed devices. Up to 195 MHz might be made available, which is a 35% increase over the present 555 MHz. Chairman Genachowski announced this initiative at CES in January. A leading application for new spectrum would be IEEE 802.11ac, which could have four instead of the current two 160 MHz-wide channels.
FCC Chairman Julius Genachowski yesterday announced an initiative to make 195 MHz of more spectrum available for Wi-Fi in the 5 GHz band.
The last time more spectrum for Wi-Fi was made available in this range was in 2003, when an FCC increased the then 300 MHz bandwidth to 555 MHz. As the document in that last link shows, the 5 GHz band is not as neat as the 2.4 GHz band, with other services, such as radar, requiring protection. These coexistence issues will have to be looked at again.
