This is the first post in the series discussing receiver diversity in a wireless link. Receiver diversity is a form of space diversity, where there are multiple antennas at the receiver. The presence of receiver diversity poses an interesting problem – how do we use ‘ effectively ‘ the information from all the antennas to demodulate the data. There are multiple ways to approach the problem. The three typical approaches to be discussed are – selection diversity , equal gain combining and maximal ratio combining . In this post we will discuss selection diversity . For the discussion, we will assume that the channel is a flat fading Rayleigh multipath channel and the modulation is BPSK.

Plenty of routers deliver more data for less money than the EA8500's $280 price tag. Still, the EA8500 is the first to use MU-MIMO techniques, which should improve over time with firmware updates, better client software and more MU-MIMO–capable hardware. When the pressure is on, the EA8500 boosts its ability to deliver the data, working best at 50 feet or more. But to get the best bandwidth, you need MU-MIMO notebooks, and, at present, there just aren't that many around. If you absolutely have to have the latest Wi-Fi technology, run out right now and buy the Linksys EA8500 router. You will likely be better served, though, by waiting for the rest of the first round of MU-MIMO equipment to arrive before investing in this new technology.
