When wireless communications systems are operating in the same general area, collisions between their transmissions are bound to occur. The collisions reduce the performance in the networks. In some wireless communications systems that use a fixed or prespecified transmission frequency pattern, a look-ahead technique that investigates the quality of the communications channel at the upcoming transmission frequencies can be used to allow or disallow transmissions. Additionally, a maximum length of a transmission can be determined based on the quality of the transmission frequency. Finally, if the communications system is controlled by a centralized controller, moving the controller away from sources of interference will often improve performance.
