I don't like to taunt, but here goes: WirelessUSB LS should never have been released: A wireless technology that works in the same band as 2.4 GHz, is proprietary (apparently) to one maker, offers lower speeds than Bluetooth, and isn't interoperable with anything?
It's funny how this offering is appearing right now, and calling itself a contrast to proprietary technology, just at the time when Bluetooth keyboards have hit the market and Bluetooth is gaining momentum. According to this article, the current WirelessUSB LS standard runs at a few tens of kilobits per second compared with Bluetooth's 1 Mbps.
This is a component maker pushing the standard, and they say in this article that "any" WirelessUSB device will work with their dongle. Any that uses chips from them, of course. The maker touts battery life, but the uses cited are all desktop uses, which means that swapping a battery or charging a unit isn't really that big a deal.
Meanwhile, they'll have higher speeds by 2005 at which time UWB will have hit the market offering 110 to 480 Mbps over similar distances, and ZigBee (802.15.4) devices will provide the battery life while achieving similar speeds -- in a standards-supported environment.
What's its real advantage? It walks and talks like USB to the operating system and the devices. Nobody need support wacky new protocols; the chips handle it. (You can read the company's FAQ; amusingly, it's a draft document containing queries and notes for revision.)
Cypress got on the wrong boat with this technology, and we won't see it adopted anywhere by anyone but perhaps game manufacturers who have USB on board and want to add wireless controller options. I'm even surprised PC World covered it.
You can read the company’s FAQ, but be warned: it’s a PDF file.
AFAICT this isn't much different from the chips that power the wireless keyboards and mice that have been on the market for years; should they never have been released too?
