From desktops to laptops to mp3 players to media centers, wireless is becoming a big part of computing, moreso with more houses having multiple computers. Many are turned off by it, though, due to very slow transfer speeds as compared to wired connections. MIMO is a newer technology designed to give wireless LANs a larger area and fast speeds. "Multiple Input, Multiple Output" has been developed by multiple partners, though Airgo Network is getting much of the credit for their work. Cisco and others are starting to include their technology in their products. It works by letting a wireless device, say a laptop, to use multiple datastreams on multiple receivers simultaneously. It potentially results in a tripling of available bandwidth. Other companies that produce competing chipsets are developing similar technologies. Atheros, one of the most popular wireless chipset producers, is using multiple antennas and multiple radios to broadcast the same datastream, slightly different but still effective.
Ultimately, this means much faster wireless for everyone available soon, perhaps within a year. The 802.11n standard, unfinalized as of yet, will bring a true 100MBp/s wireless network solution to the market that has wider ranges without needing to be amplified to extremes, with a 500' radius feasible. Once wireless connections are truly able to match the majority of home wired connections (100MBp/s Full Duplex, for instance) and in price, the only area left is security. But what an area that is.
