The method includes receiving a power mode reconfiguration command from a server that instructs the communication device to operate in a second power mode that is different than the first power mode. The method includes, in response to receiving the power mode reconfiguration command, terminating operation of the communication device in the first power mode and operating the communication device in the second power mode. A communication device with reconfigurable power modes may include an MCU, a processor (e.g., CPU) communicatively coupled to the MCU, and a non-transitory computer-readable medium communicatively coupled to the processor. The non-transitory computer-readable medium has instructions stored thereon that are executable by the processor to perform or control performance of the foregoing method. ## Claims ### Claim 1 A method to reconfigure power modes of a mobile personal emergency response service (MPERS) device, the method comprising: operating the MPERS device in a first power mode in which a communication interface of the MPERS device is continuously powered during operation of the MPERS device in the first power mode;
