IEEE 802.15.4 is a proper replacement for IR technology in remote controls because
of the low cost and long battery life of ZigBee-based wireless communication [5] . IEEE
802.15.4 can be used to create two-way communications between the remote control
and the entertainment device. For example, song information or on-screen programming
options can be downloaded in to the remote itself, even when the remote control is not in
the same room as the entertainment device.
