Abstract
A hand-held, PCMCIA cellular radio modem card is described which uses a non-standard power output level. The non-standard power output is defined as the maximum RF power attainable such that the current drawn by the power amplifier does not exceed 400 mA. This definition permits the use of the wireless modem inside hand-held computing devices without the use of an additional battery pack extension.
