Small Cell Service: If 9 Was 6
In fact, carriers are giving out mixed messages on how reliable they expect small cell service to be. In general, though, you shouldn't expect the level of service achieved by the macro cellular radio network, vendors on the Optimizing Ethernet Backhaul for the Small Cell Era roundtable suggested here Tuesday.
Both Heidi Adams, senior director of IP product and solutions marketing at Alcatel-Lucent (NYSE: ALU), and James Heney, director of marketing at Canoga Perkins , said they were getting "mixed signals" from operators about the balance between how cheap they needed small cells to be and how reliable they wanted them to be.
To a carrier, a small cell can be less reliable than a full-size base station as long as it's cheap, suggested Hossam Salib, VP of product management and marketing at Positron Inc. . "A metrocell needs to be a tenth of the cost of the macrocell," he stated.
In fact, other concerns might trump connectivity, suggested Salib. "It can go down ... but security is still important," he added.
Stuart Benington, director of portfolio strategy at Tellabs Inc. (Nasdaq: TLAB; Frankfurt: BTLA), meanwhile, suggested that the deployment of 4G might help to allay this vision of cheap and cheerful best-effort connectivity.
"You don't want to make small cells so low cost that it just becomes a glorified Wi-Fi network," Benington said. Of course, with the increasing integration of Wi-Fi and small cells, consumers might not even know the difference much of the time. (See Small-Cell, Wi-Fi Groups Aim for Integration.)
Security, bandwidth and the reliability to maintain data sessions over 4G would all be concerns for carriers and cause them to expect more from small cells. "The operators that already have a larger subscriber base on LTE will go down this path," Bennington said. [Ed note: Cough, Verizon Wireless , cough.]
Certainly none of the vendors are thinking small when it comes to the future of small cells. All agreed, with a couple of caveats, that a quarter of a million or more public access small cells -- the tiny radios that are deployed by carriers to bolster their network capacity, not in subscriber homes or enterprise locations -- could be deployed by 2015.
"LTE deployment is driving this," Positron's Salib says. "One of the carriers we're working with tops that number alone."
No matter how many of these tiny radios get deployed, however, it seems that vendors still expect the wireless broadband buck to stop with the macro network rather than expecting the smaller cells to deliver 100 percent uptime or anything close to it.
