Power savings may also be realized because in order for low power circuitry 214 to continually listen for data transmitted from other low power circuitry, circuitry 214 may constantly be operating in its “l(fā)istening” state. This state consumes power, and although it may consume more power than high power circuitry 212 operating in its sleep state, the power saved versus having to periodically activate high power circuitry 214 can be substantial. When high power circuitry 212 is in its active state and low power circuitry 214 is in its transmit state, high power circuitry 212 can consume substantially more power than low power circuitry 214.
In some embodiments, low power wireless communications circuitry 214 can be characterized by its relatively low power consumption and its ability to wirelessly communicate according to a first protocol characterized by relatively low data rates, and high power wireless communications circuitry 212 can be characterized by its relatively high power consumption and its ability to wirelessly communicate according to a second protocol characterized by relatively high data rates. The second protocol can have a much more complicated modulation than the first protocol.
