Confusion in Wireless Data> Confusion in wireless data FRIDAY, OCTOBER 01, 1999 11:54 PM - CMP Media Oct. 01, 1999 (Electronic Engineering Times - CMP via COMTEX) -- Two panels held at different locations in New Orleans on Sept. 22 reached similar conclusions about the stumbling blocks to mobile wireless broadband data services. At PCS'99 at the Morial Convention Center, John Major, president of Microsoft-Qualcomm venture Wireless Knowledge Inc., summed it up: "In voice applications for wireless, the applications for business were the same as those for the home. For a corporate user, the data applications clearly will not be the same as those for the home." And at the IEEE Wireless Communications conference at the Hyatt Regency, Alin Jayant of Saraide.com Inc. told wireless-system designers not to think of data applications the same way they think of wireline apps for the desktop. Available bandwidth in radio environments is not the only issue Jayant said; of equal importance is that mobile users differ from desktop users in the types of information they demand. The panels reached another common conclusion, voiced at PCS by Major and at the IEEE conference by Ted Hoffman, Bell Atlantic's vice president of technology development: There will be no incentive for carriers to offer true 3G broadband data services without their getting far larger chunks of spectrum than they own now. The problem is to get from 2G to 3G cellular with a coherent data strategy. The failure of specialized data nets such as Ardis and RAM, and of the Cellular Digital Packet Data standard for analog AMPS networks, have made many wireless carriers skittish about offering new data services. Despite the limitations of developing software interfaces to stripped-down Web access platforms, as the Wireless Application Protocol Forum is doing, the model of looking at the mobile platform first is the correct one. The problem is, consumers differ widely by region, social stratum and usage location (business or home) in what they expect from a handheld. That's why Qualcomm president Irwin Jacobs asserts that his company must produce baseband chips for all potential data markets. Many in the U.S. might think that such slow, circuit-oriented services as GSM's Short Message Service and CDMA's IS-95B are no big deal. But Scandinavian teens are going bonkers over SMS. The digital cellular people can't agree on a unified air interface, so coherent data strategies may be too much to hope for. But carriers and OEMs agree that wireless services must be sold via data in future generations. Here's hoping they walk their talk. By: LORING WIRBEL Copyright 1999 CMP Media Inc.
