SOMA Untethers the Last Mile

Plenty of wireless last-mile plays target Internet access, but SOMA Networks Inc. is trying something different. The startup is marketing not to end users, but to carriers, offering a setup that can provide multiple services.

The idea is to use a wireless network to hit the pockets of population untouched by DSL, or to reach the rural zones where DSL isn't practical. It's hardly a new idea. Services such as Ricochet, reanimated by Aerie Networks Inc., are delivering wireless Internet access in a similar fashion. Satellite broadband is another alternative, one that hasn't attracted large subscriber numbers but could be bolstered as RBOCs team up with satellite TV providers. (See Ricochet Rides Again and Bells Embrace the Dishes.)

SOMA's plan is closer to the satellite-RBOC idea, in that the company wants to deliver the triple-play connectivity of voice, video, and data, and do so using fixed wireless (meaning the customer doesn't move around the way a cell-phone user does). Its target customers are the RBOCs and backbone carriers, however, with its first announced customer being Japanese backbone provider NTT Communications Corp. Those customer, in turn, would use SOMA's equipment to offer broadband, particularly to businesses.

SOMA hopes to stand out by packing the connection with intelligence, letting the customer-premises terminal make adjustments for the unpredictable quality of wireless connections. Assuming SOMA can do it right, it would provide something akin to a DSL connection, but with far fewer operational hassles. The connection would be able to mend itself if the signal deteriorated, and the customer terminals could be upgraded and maintained remotely from the carrier's site.

"If you look at the way DSL is built or a cellular network is built, you're putting more on top of an existing mesh," says Greg Caltabiano, chief operating officer. "Even if the intelligence is there, there isn't a way to change the protocol."

The five-year-old startup has moved quietly so far, having raised more than $110 million mostly from individuals such as Compaq Computer Corp. founder Ben Rosen and former U.S. Senator Bill Bradley. SOMA recently landed Bank of America Corp. as well (see SOMA Seals $10M Financing).

SOMA's air interface is based on wideband CDMA (W-CDMA), but the startup had to add proprietary extensions to accommodate its antenna technology -- meaning SOMA's customers have to buy both the base stations and the customer terminals. The payoff is that its terminals aren't susceptible to multipath interference, and they can seek out the strongest signal path by continually listening in all directions.

The terminals pack the software to automatically assign priority to certain traffic types, such as voice, and they can also adjust to changing signal conditions. If coverage becomes weak, the connection will boost its level of forward error correction to compensate. "It's constantly squeezing as much out of the channel as it can," Caltabiano says. "If it sees that it's voice coming in, it will change to a low-latency channel and handle every packet carefully."

SOMA base stations can serve more than 1,000 users at 12 Mbit/s per user. On the customer side, SOMA's box plugs into whatever network infrastructure is set up: Ethernet, 802.11, or plain old telephone service. Given the amount of variation possible on the customer side, SOMA hopes to get consumer electronics firms to build the terminals.

Prices for the equipment vary depending on configuration, but a high-volume deployment often runs between $500 and $1,000 per subscriber. What the service provider avoids, Caltabiano asserts, are the heavy operating costs associated with setting up and maintaining a DSL connection.

re: SOMA Untethers the Last Mile Had to check the calendar. Nope. Lots of good laughs in this article.

re: SOMA Untethers the Last Mile Wasn't soma the drug proposed by Aldous Huxley in "A Brave New World"? It was used to keep the masses undercontrol and happy. Interesting name for a company claiming to deliver what they do.

re: SOMA Untethers the Last Mile This shows the proprietary FWBA bubble has not fully burst yet.

Hard to believe investors still keep pouring money into these kind of proprietary costly technically non-optimal outdated solutions.

Any takers on predicting whether HSPDA or EV-DO/V based solution will take over this space or would 802.16 or the newer 802.20 will establish a niche?

SFW.

re: SOMA Untethers the Last Mile I have hopes for 802.16, but I'm not betting the farm, either.

Someday, someone will finally deliver the cost savings promised by fixed-wireless for so long. It always seems to be just around the corner.

I heard that SOMA was down to their last nickle. It sounds like this article is a last-gasp effort to drum up some cash. I understand they have a good product (Albiet proprietary), but nobody to sell to.

My money is on 802.16 and 802.20. EV-DO and EV-DV don't have enough capacity and HSPDA is a function of wcdma. If wider of acceptance of wcdma is really around 2005-2006 then that puts HSPDA at around 2008-2010. Plus mobile carriers don't have the spectrum to go after the fixed market and hspda is only downlink.

More of my money is on 802.16 since product is close to being shipped. Plus the 802.20 crowd are after mobile operators. Its going to take time anyway you cut it.

re: SOMA Untethers the Last Mile 5-year old startup that hasn't produced - or sold - a product yet. Sounds like a winner to me! (sarcasm reeking out of my pores!)
