Petri Mahonen, director of the Wireless Internet Laboratory of the Finnish National Institute of Technology, primarily holds "marketing people" responsible. "They have gone ballistic, selling WAP as 'wireless Internet' or 'Web in your pocket,' which is creating a backlash effecting serious academic and industry research and development," he says. Mahonen, a research professor with the University of Oulu, is highly critical of WAP implementation in his own country (Finland is the leading user of wireless phones) and elsewhere, painting a picture of a confusing situation in which defective equipment and server products are shipped, WAP phones are incompatible, service is painfully slow and over 30% of WAP connections fail while users are charged for airtime anyway. Alan Reiter, the subject of yesterday's interview that prompted Mahonen's statement, agrees with some of the criticism, but puts a different spin on the situation: "There's no doubt that manufacturers have had a difficult time developing bulletproof WAP products. They admit it, and they also admit problems with incompatibilities. Manufacturers and carriers all understand that incompatible equipment will destroy WAP's chances. But the early days of all technologies have problems. When cellular was first introduced in the US in the early 1980s, only a few manufacturers were able to develop what was then an extremely sophisticated handset." Mahonen says that development of global GPRS (general packet radio service) will make connections more reliable but won't improve connection speed substantially. "You might be getting 10-40 kilobits per second, but that's it," he says. There is also the question of price, with the possibility that GPRS will be costly, at least initially. (Mahonen sees an alternative for the technologically advanced user to run VoIP over GPRS.) Besides concerns about WAP security (shared by almost everybody in the field), Mahonen's basic objection to the protocol is that "its philosophy is 'walled garden,' while its champions pay lip service to IP." The wall, he says, has to do with the fact that most WAP operators restrict access to their own WAP gateways and those of their partners, "so forget free surfing like on the Internet with WAP, you are in the typical closed telco world." WAP is not an open standard, he charges, but a proprietary system that is not TCP/IP-compatible, and "still unreliable" at that. Scott Goldman, CEO of the industry association WAP Forum, repeats Reiter's point about the technology presenting an "evolving situation," and says that Mahonen is "just plain wrong" in all his charges. But he accepts the 'walled garden' statement, pointing to the America Online paradigm. Just as AOL has achieved great success by providing a package of propriety capabilities for people who are not knowledgeable about technology, Goldman says, WAP offers a packaged, user-friendly service. In the future, however, "carriers can distinguish themselves" by providing alternatives, he adds. Regarding compatibility, WAP Forum claims that WAP will work with GSM-900, GSM-1800, GSM-1900, CDMA IS-95, TDMA IS-136, and 3G systems IMT-2000, UMTS, W-CDMA and Wideband IS-95. For WAP security, Baltimore Technologies, Solomon Technology, and in Mahonen's own country, F-Secure and SSH among others, are reportedly close to releasing full-strength 128-bit encryption and authentication for WAP servers, with content security programs to follow. Goldman says Mahonen is "not in the real world" because high-profile companies are already using WAP for secure transactions. As far as writing new code for WAP, Mahonen says developers "have already gone and redefined almost every stack available in the UDP/TCP/IP world, so forget IP compatibility and philosophy." He repeats the charge that WAP is just an SMS (systems management server)-with-menus, and meant to be a telco system. "Let's not fool ourselves that it is providing wireless Internet in the technical sense." Goldman contradicts that: "SMS has nowhere the capabilities and resources you get from WAP. There is already a tremendous amount of content out there. Cellmania, for example, has come up with a list of 5,000 WAP sites." Even if WAP is improved and becomes successful, Mahonen sees it as "transitional technology," especially as WLANs and 3G become more ubiquitous. With that technology, speeds are expected in the 40-100Kbps range, with a theoretical maximum of 384Kbps, with more standard, IP-compliant connections to new terminals than WAP can provide, Mahonen says. -- -------------------- janos () netcom com, SF Attachments to janos.gereben () the451 com
