Claim Text:
1. A method for transitioning from a synchronous mode to an asynchronous mode in a medium access control (MAC) of a body area network (BAN) upon receiving a switch mode command, comprising: setting a timer to a time period specified in the switch mode command for switching from the synchronous mode to the asynchronous mode within the BAN; upon expiration of the time period, tuning a device to a channel selected from a first set of channels in the BAN reserved for the asynchronous mode, wherein the first set of channels is different from a second set of channels that is reserved for the synchronous mode in the BAN; and causing the device to operate in the asynchronous mode over the reserved channel, wherein the device is configured for asynchronously duty cycling between sleep and wakeup times.
