Enhancing cellular network capacity with adaptive antennas

摘要

Wireless cellular communication is continuing to grow unabated. In many areas of the world, the demand for cellular communication is so great that operators are tempted to push the capacity of their networks beyond lev- els that current technology can handle. As wireless data applications over cellular networks become more widespread, the pressure to increase capacity will become even more intense. Capacity in the 800 and 900 MHz bands, where bandwidth is restricted, is already becoming a limiting fac- tor.
