Bluetooth operates in the globally available 2.45 GHz ISM 'free band' and provides low-cost, low power, robust, secure, efficient, high capacity, ad hoc voice and data networking of up to 1 Mb/sec, in a range of 10 meters. Unlike IRDA it does not require line of sight allowing devices to communicate with each other from pockets, bags and around corners.
Products available today that support Bluetooth include: Access Points, cable replacement, cordless phones, embedded devices, PDAs, headset, mobile phones, modems, PC Cards, portable PCs, printers, USB Devices and car kits.
