1. A wireless healthcare system comprising:
- at least one sensor configured to be positioned on a surface of a user, wherein the sensor comprises a first power amplifier and a first set of one or more attenuators, and wherein the sensor is adaptable to select a first power mode for the first power amplifier and the first set of one or more attenuators is adaptable to further attenuate an output signal at a first power level from the first power amplifier to generate a signal at a second power level, wherein the second power level is lower than the first power level; and
a base unit adaptable to be in direct wireless communication with the sensor via a communication link, wherein the base unit comprises a second power amplifier and a second set of one or more attenuators, and wherein the base unit is adaptable to select the first power mode for the second power amplifier and the second set of one or more attenuators is adaptable to further attenuate an output signal from the second power amplifier,wherein the sensor is adaptable to
1) be in direct wireless communication with the base unit via the communication link,
2) operate at the first power level in forming the communication link between the sensor and the base unit,
3) operate at the second power level in forming the communication link between the sensor and the base unit, and
4) operate at a third power level different from the first power level and the second power level to communicate with the base unit via the communication link between the sensor and the base unit after the communication link has been formed and established as an encrypted link, and wherein the sensor and base unit are components of a wireless healthcare system.
