WiLink, BlueLink chip from TI

Texas Instruments Inc. (TI) has announced two devices built on the company's DRP single-chip technology designed to drive affordable WLAN, Bluetooth and FM technologies into mass market handsets.

The first product is WiLink 6.0, a single chip that is the latest member of TI's mobile WLAN (mWLAN) family and is the first device to integrate a complete offering of mobile WLAN, Bluetooth and FM, with support for IEEE draft 802.11n for better coverage and reception. The second product is the BlueLink 7.0 solution, the latest version of TI's BlueLink Bluetooth single-chip family that integrates Bluetooth and FM. The FM functionality in both devices delivers FM transmit and receive capabilities, turning the handset into a personal area broadcast device.

Monolithic solutions
These chips are tightly integrated monolithic solutions that enable the functionality demanded by consumers, allowing them to send and receive more data on their mobile phones with an enhanced voice and audio experience. Both devices are manufactured in leading-edge 65nm technology, delivering a low-cost, low-power single chip with a small footprint.

The WiLink 6.0 device integrates mWLAN, Bluetooth and FM on a single chip, allowing handset manufacturers to quickly and seamlessly integrate these three functions into feature-rich mainstream handsets, giving more consumers access to features usually found only in high-end handsets. By integrating the first mobile 802.11n solution, consumers can seamlessly and quickly share large files such as movies and photos between their handsets and other WLAN-enabled devices, like laptops, digital cameras and gaming consoles. Operators and service providers deploying dual-mode phone solutions expect 802.11n to drastically improve voice call quality and reliability in VoWLAN applications. WiLink 6.0 will help reduce dropped calls, lowering support costs for these newer, more complex dual-mode solutions.

The BlueLink 7.0 device integrates Bluetooth technology with high-quality FM stereo transmit and receive functions on a single chip. With FM transmit capability, consumers can enjoy MP3 files stored on their phone on any FM receiver, such as car stereos or radios without wires. The chip also provides enhanced performance with support for Bluetooth Specification 2.1+ enhanced data rate (EDR). The WiLink 6.0 solution and BlueLink 7.0 device share the same Bluetooth and FM core solution, allowing customers to capitalize on their past and future software investments in a versatile manner.

'Antenna-to-application solution
Combined with single-chip modem solutions from TI, handset manufacturers have a complete "antenna-to-application" solution for mid-tier and low-end handsets. TI's WiLink 6.0 platform can work with the Omap-Vox family of solutions, including the OMAPV1030 processor and OMAPV1035 "eCosto" single-chip EDGE solution, to provide an optimized modem, applications processor and mWLAN/Bluetooth/FM solution for mid-tier handsets. Coupled with TI's "LoCosto" single-chip platform, BlueLink 7.0 is a cost-efficient solution to increase Bluetooth penetration in handsets by addressing the high-volume, low-cost emerging handset market.

TI also brings seamless cellular and WLAN connectivity for emerging IMS applications by leveraging its VoWLAN functionality provided by TI's Omap-Vox and WiLink solutions. IMS gives consumers on-the-go voice access over WLAN or the cellular network using their mobile phones.

The WiLink 6.0 and BlueLink 7.0 solutions include TI's proven robust coexistence platform which addresses system-wide interference issues, encompassing radio design and hardware and software solutions. Coexistence expertise is becoming increasingly important as more radios are being added to the handset. TI leads the market in coexistence solutions for Bluetooth and mWLAN, with more than 30 handsets using TI's coexistence platform.
