Cabling and Wireless Installation Articles 3-23-2015
Last year I wrote an article (May 2014 http://oberonwireless.com/news/blog) on IEEE 802.11ac compliant products –suggesting that products built to this standard would feature “wired like” speeds, data rates beyond 1 Gig, unprecedented user density, scalability in large venues, and better client battery life. All this new capability is provided by larger swaths of bandwidth available in the 5 GHz band and sophisticated modulation and coding schemes enabled by advanced signal processing techniques. I described in that article that 802.11ac is being rolled out in two waves, actually referred to as Wave 1 and Wave 2. I also described that Wave 2 products will engage, for the first time, Multi-User Multiple Input-Multiple Output, or MU-MIMO, technology. MU-MIMO has the ability to significantly advance data throughput. In this article I will discuss Wave 2 data rates in more detail, compared to Wave 1 and prior technologies, and implications on the wireline network. I will also attempt to make a forecast of requirements for planning cabled infrastructure into the next decade.
