Here is a fantastic primer (geeky but plenty comprehensible) on Smart Antennas. This technology holds the key to faster wireless data connections.

One specific way people talk about this is with the acronym 'MIMO' which stands for "Multiple In - Multiple Out". What this means is that
devices can now use multiple antennas on both the handset and base station to grow the data rates linearly. It was thought that adding antennas would need exponentially more power to get linearly higher data rates, but they've worked around those problems and now MIMO is being pushed in all upcoming wireless standards.

Gee [Rittenhouse, Lucent Technologies] talked about how Lucent has been driving around a New Jersey suburb where Bell Labs is located, testing the connections and are getting reliable 35-44 bits per second per hertz, as opposed to the half to 1 bit per second per hertz on current cellular networks. Where we can see 1 megabit per second in 1.25Mhz of spectrum (like a CDMA2000 channel), we can soon expect to see 30 megabits per second in that same type of spectrum. I can imagine that WCDMA which uses a broad 5Mhz wide band would see massive gains as well.
