Abstract

An apparatus may include a microprocessor and a wireless communication interface configured to perform at least one of receiving a first radio signal or transmitting a second radio signal. The microprocessor may be configured to execute at least one of a base-band encoder software program or a base-band decoder software program. The apparatus may be further configured to execute a wireless communication protocol selector software program that may be configured to optimize a value of a user-defined criterion in order to dynamically select at least one of a wireless communication network, a wireless communication protocol, and a parameter of a wireless communication protocol.
