Sirius Satellite Radio over WiFi? Agere Files Patent

Monday, October 3, 2005 at 12:16 PM

Agere Systems, the chip supplier to Sirius, has recently filed for a patent to create a repeater device that broadcasts over a wireless local area network (WLAN). The idea would be to receive the satellite signal, and reformat the bitstream received to deliver over WiFi to any number of receivers.

The patent reads like Agere is working on a simple way to allow for dependable interior listening of satellite radio. The big deal about this is that Agere will not be simply repeating one channel, the repeater would include "a plurality of channels" and then leave it up to the individual receiver to choose the channel.

This could be great for Sirius if WiFi receivers were built into their new devices. Businesses definitely would find this very useful. You could theoretically listen to satellite on your laptop, or setup "Sirius HotSpots" - gyms could rebroadcast Sirius to receivers built into treadmills.

Thanks Junior!
