Femtocell opportunities growing, panelists say

Sees potential to save consumers significant money for voice services.

With femtocells gaining more attention as a potential money-saving technology, several companies are racing to claim space in the emerging femtocell market, said members of a recent panel hosted by MassNetComms.

While the panelists -- all of whom represented companies at least partially involved in the production of femtocells -- disagreed about particulars, all of them said femtocell technology has evolved to the point where it would soon be sold in large quantities to consumers. In particular, they noted Sprint Nextel's recent rollout of its Airave devices in Denver and Indianapolis marked the first time a major carrier has sold femtocells in metropolitan markets.

"In some sense, [Sprint's early entry into the femtocell market] is a land grab," said Sanjeev Verma, the founder and vice president of marketing and business development for Airvana, a firm that specializes in broadband wireless infrastructure. "Once you go and install a Sprint femtocell in your home, and you've signed up for the particular plan, switching over to another provider becomes tougher because you've got three or four phones that are already hooked onto a particular service."

Femtocells, which are sometimes referred to as "mini-cell towers," are devices that let you use short-range cell phone frequencies to route wireless calls through your home broadband connection. Because the calls are going through individual home broadband connections, said MassNetComms Chairman E.Y. Snowden, they save consumers money that would otherwise be spent on cell phone minutes. A report by ABI Research expects femtocells to become very popular with consumers, and projects that there will be 150 million femtocell users by 2012.

Currently, Sprint offers its Airave device for US$49.99, and charges customers a flat monthly rate of US$15 for individual plans and US$30 for family plans. The panelists all agreed that this was a very good rate that should be successful at luring consumers to their products. But because Sprint is keeping its Airave rates low through subsidizing the service, some panelists cautioned the company would eventually have to figure out how to produce and deliver femtocells less expensively.

"It's a very gutsy move on their part," said Russell Cyr, the vice president and CMO of BitWave Semiconductor. "The problem will be if they get too much pick-up too quickly and they don't drive down the cost of the devices quickly, then they're going to be subsidizing them for a while in this initial period."

Cyr said another challenge for femtocells will be in making sure that femtocell users who live in close proximity to one another don't interfere with each others' voice quality by having competing signals running too closely to each other. The concern is similar to having multiple cable modems concentrated in a neighborhood, which results in slower service for users than if there were only two or three cable modems in a neighborhood.

"The first guy to get a femtocell in his neighborhood will have unrestricted bandwidth, and there's going to be no interference," he said. "But as soon as there's a hundred people in your neighborhood with a femtocell, interference is going to go up."

Verma took exception with Cyr's assertion, and argued that cable modem services, despite experiencing some temporary slowness as they initially expanded, have continued to improve as their technology has improved. He said that Wi-Fi and femtocells would follow a similar pattern.

"It is absolutely the case that some interference will be caused, but I'm not seeing a groundswell of anger in the streets that one guy's Wi-Fi is interfering with another guy's," he said.

And while femtocells have terrific potential to save consumers money on their voice services, the panelists said they weren't quite certain when consumers would consider the technology to be inexpensive and effective enough to be worth their investment.

"The industry has to get itself very quickly to the point where you plug it in, and it works for the average consumer," Cyr said. "If we have to rely on technologists to turn these things on and make them work, then they're going to spend a lot of expense here very quickly."

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
