Phones go Wi-Fi

Texas Instruments has unveiled its third generation 802.11 solution specifically designed for mobile devices such as cell phones, smartphones and PDAs.

With cell phones and mobile devices becoming the prevailing communication and entertainment devices for consumers, Wi-Fi connectivity provides faster speeds so consumers can download more information, photos and music faster.

The new chipset can be configured for 802.11b/g or 802.11a/b/g operation using different WLAN RF solutions from TI.

The two-chip 802.11b/g solution combines the TNETW1250 single-chip MAC/baseband processor with the TNETW3422M radio frequency front end (RFFE) and power amplifier chip.

Designed to be used with TI’s OMAP application processors, GSM, GPRS, CDMA and EDGE chipsets and single-chip Bluetooth solution, the chipset sports on-chip power management, re-use of cellular clock frequencies, and low pin-count host interfaces.

TI also released details on the TNETW3422M, a 2.4GHz single-chip, RF transceiver and power amplifier. This radio, which uses direct conversion architecture, is also suitable for use in a cellular handset.

The chipset is expected to be in production mid-year.
