U.K. chip maker CSR is hoping to steal...

Special Interest Group (SIG), which runs the Bluetooth licensing program. “CSR Mesh,” as CSR is calling it, works as a mesh radio network like Zigbee, but without the need for an additional network hub or router, CSR said. This is possible because all modern smartphones and tablets come with enhanced Bluetooth smart capability “out of the box,” it said. CSR Mesh lets one smartphone control a virtually unlimited number of devices, such as lights, heating or security, with plug and play set-up, it said. CSR is now pledging to donate its CSR Mesh technology to SIG on a no-royalty basis, it said. At the London exhibition, Rick Walker, senior product marketing manager for CSR in Cambridge, demonstrated a prototype LED home lighting system similar to the Philips Hue, but using CSR Mesh instead of Zigbee. “CSR Mesh is disruptive,” Walker said. “It puts the smartphone at the center of the Internet of Things. We developed a software protocol that runs over the smart standard to create a mesh network at the standard Bluetooth frequency of 2.4 GHz, controlled by standard Bluetooth hardware.” Now that CSR has shown what can be done, “there are some big nasty competitors out there that will want to develop their own systems and fragment the market,” Walker said. “We want to avoid a situation like the zillion different standards for Wi-Fi, so will donate our technology to SIG and let SIG give free licenses. This is imminent.” CSR first announced the system in February and will release technical details on its website by the end of July, Walker said. “Then, early next year, we will offer everything, except the source code, to SIG to license without royalties.”
