1. An information handling system comprising:
a housing;
a processor disposed in the housing and operable to execute instructions to process information;
a memory disposed in the housing and interfaced with the processor, the memory operable to store the instructions and information;
a wireless interface module having a primary radio, a secondary radio and a processing resource; and
plural peripheral devices, each peripheral device separate from the housing and including a peripheral wireless interface module having a peripheral primary radio, a peripheral secondary radio and a peripheral processing resource, each peripheral device operable to transmit information with the peripheral primary radio to the wireless interface module primary radio using a wireless personal area network protocol having pairing information that includes wireless transmissions at a defined intervals, each peripheral device includes a human interface device to accept end user inputs for communication to the processor; and
a non-transient memory integrated in each of the peripheral devices and storing peripheral instructions that when executed on the peripheral processing resource:
store an individual wake command and a group wake command having a wake protocol;
monitor with the peripheral secondary radio for communication of the individual wake command and group wake command; and
in response to an individual wake command or group wake command received at the peripheral secondary radio, wake the peripheral primary radio, initiate pairing by the peripheral primary radio with the wireless interface primary radio, and sleep the peripheral secondary radio;
wherein the wake command comprises information modulated with an On-Off Keying protocol and including at least some of the wireless personal area network pairing information.
