Meru APs work at 100% power all the time to maximize coverage. Because Meru uses virtual cells in a single frequency, this leaves the other two channels in 2.4GHz for example, available for different overlay networks that are completely independent or to support higher client densities such as an extremely large space that requires 1500 clients to connect. This means you can run 802.11n on channel 1 (or on two channels (say 1 and 6) in 2.4GHz can be bonded to provide up to 300Mpbs) and you can still overlay a network running 802.11bg on channel 11 without any interference – two networks that can be optimized for throughput for 802.11n and a second for 802.11abgn. All of the 5GHz channels are also potential overlay networks so achieving high density is fully supported.
Centralized controlled sessions allows for ‘zero delay’ in handing off a session from one AP to another. Most other solutions require the client to request handoff introducing possibility of dropped sessions or calls, latency, and jitter – less than ideal for VoIP. Meru supports ‘through-the-air’ Quality of Service to guarantee performance in a wireless LAN infrastructure.
