Although the 5GHz band offers multiple 40MHz-wide channels, the reality is that many deployment scenarios will require some form of cell-planning, which presents a challenge given the unpredictable coverage caused by MIMO. The figure below shows how a cell-based solution is prevented from creating a predictable coverage environment. Each AP will have sporadic and changing coverage, which will inevitably impact other APs using the same channel.

Extricom is the only technology immune to cell-induced problems and variability of MIMO coverage. In fact, because MIMO improvements are opportunistic, the Extricom architecture actually improves MIMO performance by providing the "best" MIMO path on a packet-by-packet basis to a wireless client, thus adding robustness and stability to a highly variable technology. MIMO doesn't mess up your cell plan, because there's no cell plan to mess up!
