NXP Semiconductors has announced an enhanced system solution enabling mobile users to simultaneously take advantage of handsets' Bluetooth and WLAN capabilities. The NXP Nexperia cellular system solution 5210, incorporating an unlicensed mobile access (UMA) software stack from Kineto Wireless, allows devices to be used at home over fixed-line broadband networks and while on the go via a cellular network. The simultaneous usage of Bluetooth and WLAN enables these calls to be made using a Bluetooth headset.

To overcome the challenges of operating WLAN and Bluetooth in the same frequency band and physical co-location without degrading data throughput or voice/audio quality, NXP has integrated a complex set of coexistence algorithms into the 5210's base band, its low-power BGW211 WLAN and Bluetooth solutions. This enables both connectivity functions to operate simultaneously without interference while delivering a compelling end-user experience. Additional algorithms have been added specifically for voice applications, ensuring crystal clear communications when using a Bluetooth headset.

Incorporating NXP's UMA technology with a Kineto Wireless software stack, the flexible solution requires no additional setup by the consumer. UMA-enabled devices switch seamlessly between cellular networks and Wi-Fi hotspots, automatically detecting the fastest and most cost-effective network–reducing phone bills and increasing network coverage. UMA is particularly attractive to business users, with Wi-Fi use in offices, airports and hotels growing exponentially, offering substantial savings in mobile bills.

As a highly integrated and small form factor cellular system solution, the 5210 can be easily designed into new devices, ensuring minimal development costs and accelerating time to market. Combining a powerful single core with NXP's BGB210S for advanced Bluetooth 2.0 EDR and NXP's 802.11g WLAN (BGW211) with industry leading low-power performance, NXP's latest system solution delivers an effective and intuitive multi-media experience on mobile devices.
