Dossier: Proxim Corp.

Wireless-equipment vendor Proxim Corp. had its share of static.

By any measure, 2003 was a breakout year for many wireless-communications companies. For Proxim, it was a year of trying to put the pieces back together.

Proxim replaced its chief executive officer, closed two out of three manufacturing facilities, and cut its workforce in half-to 330 workers. The wireless local-area network equipment company also continued a string of losing quarters-for the second and third quarters of 2003, it lost a total of $84 million on revenue of $70 million.

Meanwhile, other wireless-communications vendors saw unit sales increase. In the third quarter alone, wireless-hardware unit shipments were up 22% over the previous quarter, according to market watcher In-Stat/MDR.

So if wireless is going gangbusters, why does Proxim continue to post losses?

Analysts say the company's challenges include the fact that wireless networking has become a commodity and that, unlike many competitors, it doesn't have a wireline offering. "[Wireless-equipment] prices have just plummeted, so there's not a huge profit margin-and there's no significant differentiation between the players," says Tim Scannell, president of Shoreline Research, a research and consulting group. For instance, wire-less access points, which connect wireless devices to a wired network, cost as much as $500 two years ago but now go for about $150.

Ken Haase, Proxim's director of product marketing, acknowledges that margins are getting squeezed, and says the company has staked its future on "convergence": seamlessly uniting wireless voice and data transmissions from outdoor to indoor networks.

That plays to the company's strength. Proxim is an amalgam of three wireless-equipment vendors. In March 2002, Western Multiplex, a supplier of inter-building wireless-networking products, acquired Proxim Inc., a struggling provider of wireless gear for consumers and businesses. The combined company took Proxim's name, then in June 2002 purchased the Orinoco line of adapters and access points from Agere Systems.

The reborn Proxim Corp. tried to cherry-pick the best equipment of its forebears, and now offers customers both indoor and outdoor wireless gear that conforms to Wi-Fi, the industry's term encompassing the 802.11a, b and g wireless-networking standards.

Some organizations have overcome hesitation to embrace Proxim's offerings. At the Berklee College of Music, for example, director of networking and telecommunications Roy Galang says the school has deployed just half of its planned 200 access points because of early concerns about complexity that soon proved unfounded. "We didn't know how easy this would be," Galang says of Berklee's Proxim implementation.

The Baptist Health System of East Tennessee started using Proxim Inc.'s RangeLAN2 wireless products six years ago and is in the process of switching over to Orinoco access points.

Rick Simpson, the hospital group's senior system specialist, says he briefly looked at upgrading to Proxim's now-discontinued Harmony line of access points, but those units, he says, were "dumb": They couldn't be individually programmed or maintained. They also relied on a single controller component; if that went down, so did every unit in the network. But around that time, Proxim began offering the Orinoco units, which Simpson says are more intelligent and fail-safe- a crucial consideration, because the availability of the network (and the medical data flowing over it) directly affects Baptist's patient care.

"Even when the [wired] network went down, the wireless segment has never gone down," Simpson says. "It's one of the most stable systems we've ever had."

Proxim's next major technology hurdle is Maestro, a project being developed in conjunction with Motorola and Avaya. Due to be rolled out this year, Maestro is supposed to deliver uninterrupted outdoor-to-indoor cellular phone service over a secure, proprietary network.

But all of Proxim's product developments have been in the wireless space. And market watchers say the company is at a strategic disadvantage to major competitors because it doesn't sell wireline networking systems such as Ethernet switches.

According to Gartner analyst Ken Dulane, many enterprise customers want their wireless setup to be an extension of their core wired network instead of assembled parts. "That gives a big leg up to the incumbent vendors," Dulane says, "and Proxim doesn't have a business in that area."

It also doesn't have the profits of larger, healthier competitors like Cisco, which recently posted year-end net income of $1.1 billion.

The Technology


Wireless networks in the workplace typically have a maximum range of only about 300 feet. So what can a technology department do to extend its network's reach, short of new wire?

Proxim's answer to this riddle is to let its Orinoco access points act as "repeaters" that catch and resend wireless transmissions in a point-to-point fashion, like a cutoff man relaying an outfielder's throw to home plate. That allows a wireless local- area network to extend into areas without Ethernet wiring, such as an open parking lot.

The key is to avoid signal congestion, so the Orinoco access points have a dual-slot configuration, which allows them to simultaneously send and receive signals. Like the "In" and "Out" doors of a busy restaurant kitchen, the two slots function independently: A departing packet of data isn't hogging the only point of entry as another packet comes whizzing by. Instead of needing to wait, the arriving data comes in through the second slot.

A different approach-promoted by Cisco, Intel and others-is a "mesh" wireless network architecture in which multiple nodes act as routers, relaying data to their nearest neighbor. Proxim, however, points out that this multipoint design is apt to function less efficiently than its own point-to-point repeaters. That's because in a mesh, many nodes are contending for the same spectrum, and that interference degrades overall performance.
