Extreme Networks and "Think Mobile" as a strategy

The networking company's VP for Asia Pacific and Japan Sales, Gary Newbold, on the past, present and future of connectivity and mobility.

Implication of 256 QAM Modulation: 802.11ac uses 256-QAM, which is four times higher than the 64-QAM standard used on 802.11b/g/n. While this translates to higher throughput, 256-QAM requires more stringent conditions for it to work, such as a clean RF environment and a greater signal-to-noise ratio. For the organisation, this means more access points (APs) are required, since clients will need to be physically closer to the AP in order to acquire a strong signal. Otherwise, transmission rates will be automatically downgraded to the previous 64 QAM modulation. 

By taking into consideration these three key requirements before deploying the 802.11ac technology, organisations will ensure a successful outcome with 11ac projects.
