Cheap Wireless for Accessories

Posted by michael on from the wires-are-so-last-century dept.

morcheeba writes "Yet another wireless protocol for personal computers! In addition to existing 802.11 variants, bluetooth, and ultra-low-power newcomer zigbee, Cypress semiconductor is releasing a simple low latency, low cost (<$2), medium speed (200kbit/sec) protocol with USB human interface devices (HID) compatibility. Partners include Saitek (game controllers) and NMB (keyboards & mice). EETimes has an informative article."

  1. WirelessUSB's niche by Ryanwoodings · · Score: 5, Informative

    I am one of the main designers of WirelessUSB LS at Cypress and have been involved with in WirelessUSB R&D for almost a year. Let me clear up a few misconceptions about WirelessUSB LS (LS is the low speed version with data rates maxing at 64 kbps).
    It's main competition is 27 MHz proprietary technologies. It only overlaps Bluetooth in areas that Bluetooth is weak in the first place such as HID devices where Bluetooth has power management and latency issues.
    Currently WirelessUSB LS will be used in point-to-point connections that do not require standards-based protocols such as wireless mice, keyboards, gamepads, remote controls, garage door openers, etc. Does anyone care if their garage door opener uses an IEEE standard? :-)
    If your devices need to interoperate with one another or you need high data rates go with another technology, but if you just need a cheap, easy-to-use low speed, short range (sub 100m), point-to-point reliable wireless connection that will not interfere with Wi-Fi traffic and can handle co-location of hundreds of devices than WirelessUSB LS is the clear winner.
