Covad Plots 'Pre-WiMax' Service

DSL provider Covad Communications Inc. (OTC: COVD) isn't waiting for official Wimax products to launch a broadband wireless service offering -- probably in the first quarter of 2006 -- that promises better than copper performance for its high-end customers.

If it sticks to that schedule, Covad will be one of the first established players to launch a fixed WiMax-like service. Sprint Corp. (NYSE: FON) recently said that it plans to launch WiMax services in 2007 (see Sprint Firms Up WiMax Plans). AT&T Corp. (NYSE: T) is plotting a large trial of the technology in the fourth quarter of this year (see AT&T Plots WiMax Trial ).

Covad has been actively testing so-called "pre-WiMax" OFDM products since the fall of 2004. The firm has been running a technical trial using four 5.8GHz base stations in San Jose and Oakland, Calif. Ron Marquardt, director of product development for the alternative access services group at Covad, says that firm has "close to 20 users" on the network right now.

"We're looking at the first quarter of next year" for a commercial launch, says Marquardt. He wouldn't go into details about where the firm plans to roll out services or what equipment vendor -- or vendors -- it plans to use.

But Marquardt does say that Covad won't wait for equipment that has the official seal of approval from the WiMax Forum to start offering its service. The first round of WiMax interoperability tests is due to start this month, and WiMax-branded product is expected on the market late in 2005 or early in 2006 -- right around when Covad actually hopes to launch its offering.

And Marquardt says that Covad is happy to use pre-WiMax kit for its fixed wireless service. "Frankly, the fixed services are not really a big focus of the WiMax Forum," he opines. "That's being driven by companies that are very interested in mobile." (See Mobile WiMax Faces Struggle and WiMax: A Spec Divided.)

Covad says it will use the broadband wireless kit to offer customers a high-speed alternative to DSL. The firm claims it consistently achieves links up to 5 miles from the wireless broadband base station at speeds as high as 5 Mbit/s. In contrast, DSL technologies are unable to make links at that distance, and at 2.5 miles or so from a central office, ADSL will be limited to speeds less than 1 Mbit/s.

"It is offering speeds that you can't do over copper," says Marquardt.

Covad's approach to WiMax-style services most closely mirrors that of startup TowerStream Corp., which has carved out a business for itself supplying business customers in markets like New York and San Francisco with high-speed wireless links (see TowerStream: Unwired in the City).

This model is quite different from the idea of using WiMax to offer broadband services in rural areas that are difficult to wire up. The rural broadband usage model has been touted by vendors like Cisco Systems Inc. (Nasdaq: CSCO) as well as many analysts (see WiMax: Town & Country).

It's probably too early to predict which will be the more profitable business model: High-speed urban wireless delivery or rural broadband deliverance.

Squeeeeeeeeeeeeeal!

re: Covad Plots 'Pre-WiMax' Service
Hi,

We are comparing apples with oranges in term of bandwidth. WiMax's bandwidth is shared. DSL is not.. So, DSL provide 1Mbps to each link while the WiMax shared the whole X Mbps to the whole group of users for each radio.

In urban area like USA, you have choices. You could get DSL with exclusive 1Mbps with very low price which WiMax try to compete with shared X Mbps. The DSL may give you better performance..

A more fertile ground for WiMax type of product will be dense urban area in Asia where DSL servcie is not widely available or use WiMax as filled in coverage for DSL.

Interference is likely to be the big issue in urban environments. All the initial WiMax rollouts in the US are using unlicensed public bands. Hard to say how big of a problem it will be yet.

re: Covad Plots 'Pre-WiMax' Service
I have always felt that the "Rural WiMax" pigeonholing was bogus. If the economics of WiMax are so superior to DSL that it even works in rural areas does not, why would it not work even BETTER in urban areas? Line of sight issues? Interference?

If these issues do not hamper urban service, then covering even more people with one base station is more profitable, implying that WiMax is indeed economically threatening in urban settings.

re: Covad Plots 'Pre-WiMax' Service
Is the unlicensed BW for current deployments part of the BW that congress plans to reclaim along with/in addition to that from the digital to analog TV conversion?

Here comes the Telecom Bill reform $$$.

The FCC will have riots on their hands if they try to reclaim one Hz of spectrum. I have been involved with spectrum allocation. It does not happen quickly or painlessly.

I take it then that LOS is not a WiMax issue in the 5.8GHz range?

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
