Ethernet will help small cells take off in the enterprise, says Airvana

The company's new OneCell system communicates using Gigabit Ethernet

Airvana's next-generation LTE small cells for enterprises use Gigabit Ethernet to connect to a central controller, making the mini base stations easier and cheaper to roll out at the office.

Rising smartphone and tablet use in enterprises means that productivity with those devices hinges on robust wireless coverage and capacity. Building a Wi-Fi network is the natural choice, but a growing number of vendors are developing products to improve indoor cellular coverage.

Airvana's new OneCell system for midsized and large enterprises consists of a centralized controller and multiple small cells called Radio Points. The Radio Points connect to the controller using standard Gigabit Ethernet switches and cabling, according to Vedat Eyuboglu, co-founder and CTO at Airvana.

"The cost is going to be comparable to that of a managed Wi-Fi network," Eyuboglu said.

Enterprises typically use distributed antenna systems to improve indoor cellular coverage, but those systems are more expensive and complicated to install, according to Mike McFarland, director of product management and marketing at Airvana. The company's small cells also offer more capacity.

Using a centralized controller instead of stand-alone small cells makes it easier to handle interference and improves performance when users move from one small cell to another. The architecture also lets multiple operators share an installation.

The OneCell system is now in trials and will be generally available during the first quarter of next year.

Airvana isn't the only company with high hopes for small cells in the enterprise. The whole telecom industry -- including chip makers, equipment manufacturers and operators -- is showing a growing interest.

For example, on Monday Cisco Systems announced Small Cell Enterprise Select, a program that aims make it easier for operators to roll out enterprise small cells more cost effectively.

On Tuesday, Alcatel-Lucent announced that Uruguayan operator Antel and Danish operator TDC had would use its enterprise small cells to improve capacity and coverage.

Airvana, Alcatel-Lucent and Cisco were, along with ip.access, the market-share leaders during the first quarter, according to Infonetics Research. The market research company expects that enterprise adoption will help sustain an annual growth rate of 77 percent from 2013 to 2018, it said.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
