The GSM Association (GSMA), an industry group composed of mobile operators, wants to see third-generation (3G) cellular technologies used for wireless broadband in notebook PCs, but operators will have to change their way of doing business to make that happen.3G technologies like wideband code division multiple access provide data at downlink speeds up to 384Kbps, but advances in 3G technology, like high-speed data packet access (HSDPA), offer speeds of 3.6Mbps or more.Cellular operators have pinned their hopes on these new high-speed technologies to boost their mobile data business. "We\u2019re not simply providing voice; we\u2019re all going after the data market in a very significant way," said Craig Ehrlich, chairman of the GSMA\u2019s board of directors and a director at Hutchison Mobile Communications, speaking at the 3GSM World Congress Asia conference in Singapore last week.As part of these efforts, GSMA is working with Intel to make HSDPA support a standard component of notebook computers, alongside existing Wi-Fi access and planned support for WiMax. "Mobile broadband\u2014HSDPA\u2014is becoming and will become a standard feature of notebook PCs," said Rob Conway, the GSMA\u2019s chief executive officer.Others are not so sure HSDPA will be widely used for mobile access."Irrespective of what people say, 3G is about voice. There\u2019s no question about that," said Ray Owen, the Asia-Pacific director of wireless broadband at Motorola, adding that WiMax and Wi-Fi have important roles to play. "It\u2019s not necessarily that cellular technologies will do everything," he said.The principal problem with 3G and HSDPA is cost. Rates for 3G data services are high in most countries, making the technology ill-suited for heavy data access, with the exception of wealthy customers and some business users.In Japan, which was the first country to get commercial 3G services, users pay a flat rate for sending e-mails or surfing the Web from their handsets. However, PC users who access the Web over 3G networks pay much more. Computer data access costs roughly 0.20 yen for one packet, or 128 bytes, to download data over 3G networks.As a result, when notebook users in Japan cannot access a Wi-Fi connection, they often rely on personal handyphone system (PHS)\u00a0cards rather than 3G cards for mobile data access. PHS services are charged at a flat rate of 12,915 yen (US$108) per month for 256Kbps access or 9,765 yen for 128Kbps.3G data plans are often cheaper in other countries, but these services are not intended for mass adoption. In Singapore, MobileOne offers unlimited access with a 3G data card for Singapore $68 (US$43) per month. That service is geared to business users, who are more willing to pay for premium services, rather than the average consumer.While GSMA is working with handset makers to bring down the cost of 3G phones, the group has no intention of pushing operators to lower the costs of 3G services, Ehrlich said. "The one thing GSMA does not get involved in, for antitrust reasons, is pricing," he said.There is plenty of incentive for operators to keep cellular data costs high. "If you were to calculate the bandwidth you are consuming on the cell site, compared to voice, you should be charged a phenomenal amount for that access," Motorola\u2019s Owen said, citing the profitability of voice calls to mobile operators.If operators want to make cellular more competitive for data, they will have to rethink their business model. "The voice charging model works very well for voice, but translating that into the data world isn\u2019t necessarily going to be as successful," Owen said. \n\n-Sumner Lemon, IDG News Service (Singapore Bureau)(Martyn Williams, in Tokyo, contributed to this report.)\n\nRelated Links:\n\nGSMA Gets 10 Bids for Low-Cost 3G Handset\n\nWeb Leaders: Mobile is Tough Nut to Crack\n\nExperts: Don\u2019t Copy Web 2.0 Directly to Phones\n\nUltra-Low-Cost Handset Market Taking OffCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
