 A cognitive radio system is what can be automatically optimized and designed to use the best wireless networks in its proximity to avoid user intrusion and congestion. Such a radio automatically identifies channels available in wireless spectrum, then modifies its transmission or reception dimensions to permit more simultaneous wireless communication at one destination in a given spectrum band. The cognitive radio system is capable of customizing radio-system parameters in response to the operator's instructions. This operates as an independent device in the networking system, sharing ambient knowledge with the networks it accesses, as well as other cognitive radios. A CR continuously monitors its own efficiency, as well as reading the radio outputs.
