Dynamic reconfiguration of a wireless network using flexible wavelength multiplexing

摘要

A wireless communication system which is reconfigurable to accommodate varying traffic density is provided by using a flexible optical interface between a base station controller and several base stations. Communication between the base station controller and the base stations is provided over an optical fiber. The fiber carries several communication channels in both directions using wavelength multiplexing. The bandwidth between the base station controller and a particular base station is varied by increasing or decreasing the number of wavelengths used to communicate with the base station. Varying the bandwidth provides the ability to adjust the capacity to carry voice and/or data between the base station controller and the base station. As a result the number of radio frequency carrier frequencies assigned to a base station can be varied to support varying radio frequency traffic density throughout the wireless network.
