| Tri-wireless roaming gets kick-start |
||
 Manhasset, N.Y. - Texas Instruments Inc.'s demonstration of an integrated Wi-Fi, cellular and Bluetooth personal digital assistant captured one of the overriding themes of last week's CTIA conference in New Orleans: Wi-Fi-to cellular roaming. However, TI also opened a veritable Pandora's box of technical and marketing questions. Given the pervasiveness of cellular technology and the rise of Wi-Fi hotspots, TI's Wanda concept design proved a nice fit with numerous wireless-carrier announcements at CTIA. Collectively, the introductions appear to put to rest many of the disagreements during the past two years over the level of wireless integration that can be delivered in a single handset. But stubborn technical questions of power consumption, coexistence and footprint for such a triad solution may not be easily laid to rest. And the market debates go to even more fundamental issues concerning cost, carriers' acceptance of Wi-Fi as a workable complement to their wide-area voice-and-data networks, and the true viability of Bluetooth. Ongoing interoperability problems have put that short-range wireless technology in the shadow of low-cost Wi-Fi. http://www.siliconstrategies.com/story/OEG20030324S0024 |
