TI introduced a new wireless PDA design with GSM/GPRS, Bluetooth, 802.11 and an OMAP Processor - in one device

The tri-wireless PDA concept design, code named "WANDA" for Wireless Any-Network Digital Assistant, is the first PDA design to integrate TI's wireless LAN, Bluetoothâ„¢, and GSM/GPRS technologies for simultaneous voice calls, wireless web access and personal area networking. Primary TI components and their functions include:

  • Application processing is handled by the OMAP1510, an ARM925 and TMS320C55x DSP.

  • Bluetooth connectivity is provided by TI's BRF6100 single-chip device that integrates digital RF and
    Bluetooth baseband on one chip.

  • The TNETW1100B is TI´s single-chip MAC and baseband processor for 802.11b.

  • The TCS2100 GSM/GPRS digital and analog baseband, power management and software protocol stack for

  • The unique design of WANDA provides several benefits to OEMs and ODMs, network operators, and end-users.

First, with a complete reference concept design like WANDA, OEMs/ODMs can save months in the development cycle and deliver products to market faster. Manufacturers can also create multiple designs from the same platform to reach different market segments due to the modular design. This modular approach also which reduces parts count up to 25% compared to other Pocket PC wireless PDAs.

Network operators can also benefit from the modular design as products can be tailored at both enterprise users and consumers. The tri-wireless capabilities and Pocket PC OS provides for deployment of new applications like instant voice messaging, picture sharing, simultaneous GSM voice calls and internet browsing. These elements - tri-wireless capabilities combined with new applications - contribute to a higher average revenue per use (ARPU).

For end-users, WANDA's wireless integration of data-centric and voice-centric capabilities into one device provides higher levels of utility in a sleek form factor. In addition, end users will enjoy higher performance while maintaining low power consumption for extended battery life due to DSP-accelerated multimedia functions on the OMAP1510.

My fellow MVP Dale from Pocket PC Passion saw it live at CTIA Wireless; see his picture and impression here.

This is a pretty interesting concept as it combines my three famous wireless technologies! Well done TI! However, I wonder what kind of integrated wireless chips we will see for 3G devices? I mean here you have to work as triple band and mode: GSM 900/1800/1900, GPRS and 3GSM. Plus adding Bluetooth and IEEE 802.11:?: Ouch, this seems to be not possible to be realized during the next months we will need this kind of reference designs.

Regarding the device design, it's a concept only, for me it looks a little bit strange - don't know if I like it or not. ;-)
