As they often do when they're not happy with the way things are going, a collection of tech-heavy hitters led by Intel may be trying to take control of an important standards process — in this case, for next-generation Wi-Fi.

Monday's announcement of a group called the Enhanced Wireless Consortium (EWC), led by Wi-Fi chipmakers Intel, Broadcom, Marvell and Atheros Communications, is the latest example of a long tradition in tech: The big guys, one way or another, usually end up calling the shots on standards.

The seeming momentum of this Intel-led group comes after a long and fractious debate over what should be in a standard called 802.11n. And it has some wondering if the Institute of Electrical and Electronic Engineers (IEEE), which usually leads standards debates, and perhaps even the industry's traditional standards-setting process, are becoming irrelevant.

"It's a very good question," said Craig Mathias, a principal analyst at the Fairpoint Group. "The whole process has definitely gotten more political over the years. The technology used in this standard is the future of wireless (local area networks). It's very important for companies involved to get their market positioning up-front and establish themselves as players as soon as possible."

The 802.11n working group was formed within the IEEE about a year ago to establish a standard for a new Wi-Fi technology called MIMO (multiple input/multiple output) that will quadruple data rates of wireless LANs.

The 802.11n specifications are critical to the development of the Wi-Fi market, which needs higher speeds and larger ranges to accommodate more consumer electronics products on the network. Critics argue that the Intel proposal is too PC-centric, while the originally IEEE-sanctioned group is working on something that is more inclusive of consumer electronics devices.

The process has been mired in squabbling between rival groups: One led by Intel and the other by Airgo Networks, a small company with the only MIMO-based chips now shipping. Earlier this year, the two groups came to a deadlock after an Intel-backed proposal failed to get the necessary votes to push it forward. Since then, members of the two groups have been working to develop a new joint proposal.

Intel and 26 other companies lobbed a curveball into the IEEE process when they announced the formation of their group. A committee still operating within the traditional standards process also plans to submit a proposal to the IEEE at its November meeting.

The Intel group claims that it wants to help accelerate the IEEE process and get the standard back on track. But at the moment, it's unclear whether the splinter group's proposal will actually speed up the process.

Some analysts worry that the squabble could easily become a stalemate and deepen an already polarised situation. The new group initially rebuffed Airgo, which pioneered and leads the market in MIMO antenna technology. Several mobile-handset manufacturers, such as Nokia and Motorola, have not joined the Intel group because they believe that its specification is too PC-centric.

A similar situation has played out with other developing standards, such as ultra wideband, a short-range wireless technology that rivals Bluetooth. Problems with UWB stem from a stalemate between groups led by Motorola and Intel.

"The ultra wideband standards process has definitely gotten bogged down in politics," said Sam Lucero, a senior analyst at ABI Research. "And by my estimates, it has completely stalled out. Intel doesn't want Motorola to get too far ahead in the market. It's very similar to what's happening in 802.11n, where Intel doesn't want to see Airgo get too far ahead."

But some wonder if an IEEE stamp of approval is even necessary for companies like Intel and Broadcom to gain an edge in a market that promises to generate billions of dollars in revenue in the next several years.

Instead of waiting for the official standard, which isn't expected to be completed until the beginning of 2007, companies in the Intel group can start building prestandard MIMO products with the assurance that products will at least be compatible with those from market leaders like Intel and Broadcom. Products could ship as early as the fourth quarter of 2006, according to Philip Solis, a senior analyst at ABI Research.

In the end, the specification that gets a critical mass of products behind it becomes what everyone works with, regardless of whether an official standards-setting group likes it.

Some worry that such behind-the-scenes work unfairly excludes some companies. "Intel and Broadcom started drafting this proposal in March," said Nico van Waes, senior research engineer at Nokia. "And in the July time frame, they came to several companies and said not to tell anyone that they had this proposal."

He said Nokia originally didn't join the Intel effort because it was worried that the chip giant was trying to bypass the open-standards process. Indeed, competitors have complained that the
