rate curve all systems are modeled by comparing the nominal power of the signal to the noise power such systems are engineered to provide as much nominal signal power as possible in relationship to the noise power in the expected communications channel claude shannon developed a by now classical formulae that express the amount of information that can be transmitted through a communications channel given the bandwidth of the channel the signal power and the noise power c b u00b7 log 2 u2061 1 p n o u2062 b b u00b7 log 2 u2061 1 e b n o u00b7 r b b the implication of the shannon formula above is that as signal power increases or as noise power decreases the allowable bit rate will increase engineers work diligently to design communications systems with the least noise and the maximum practical or allowed signal power in order to maximize the quality and speed of the information transmission most radio communications systems whether they are wired or wireless have a maximum allowed nominal power or effective radiated power erp thus it is frequently at this highest allowed limit that radio transmissions are transmitted unfortunately in the case of a battery powered device transmitting at the highest power level also drains the battery most quickly another unfortunate effect is an increase in out of band emissions these are strictly regulated but even at the regulated levels these emissions are additive and pollute the radio spectrum out of band emissions tend to become additive and raise the common radio noise floor to ever higher levels which as indicated by shannon 39 s formula reduces the capacity of any radio channel the present invention addresses this problem of accelerated battery drain and contribution to radio spectrum noise.
