If you're not tired of hearing me complain about the overabundance of wireless protocols, here's one more to add to the mixanother Ultra Wideband (UWB) competitor. This time it's called Continuous Wave UWB, and it was developed by Pulse-Link.
What makes this spec different is that it doesn't employ any analog mixers or local oscillators. Hence, it's a simpler design. How it works is that it makes use of variable spreading codes that can trade data-rate for range. Its spectral characteristics are flexible enough to satisfy different regulatory constraints.
The developers claim that Continuous Wave UWB offers a data rate of 1 Gbit/s with a range of 10 m. Pushed back to 80 m, it still exhibits a rate of 10 Mbits/s.
Bottom line: it's an interesting technology. Unfortunately, we already have enough interesting technologies to deal with.
