Claim Text:
1. A method comprising: detecting whether a transmitter of an apparatus has information to transmit, wherein detection whether the transmitter of the apparatus has information to transmit comprises detecting whether a level of transmission signals exceeds a specified threshold; in response to detection that the data in the level of transmissions has changed between exceeding and not exceeding the specified threshold, determining to change a power state of a power amplifier of said apparatus between a high power and a low power state, wherein detection of the change between exceeding and not exceeding the specified threshold and determining to change the power state are performed in a time less than or equal to the time taken to perform processing of data for transmission; in response to a determination to change the power state of the power amplifier, causing the power amplifier to change the power state; and wherein said detection is carried out within a radio portion of said apparatus.
