Case Study
Small Georgia College Rolls Out 802.11n Network
9/10/2008
Cost is an issue with any wireless network project, and, for the smallest schools, it can be an overriding factor. But 700-student Emmanuel College, located deep in Georgia, brought the cost of a new 802.11n network under control by initially focusing on strategic areas such as its residence halls. It's also saving money by eliminating the high cost of continual IT staff repairs to the previous wireless system.The private, four-year Christian college, nestled in the foothills of the Blue Ridge Mountains, had plenty of standalone 802.11g wireless access points scattered across its 150-acre campus. But the campus is also dotted with sturdy vintage buildings with thick walls and other structural impediments common to higher education. Connectivity to wireless access points (APs) would disappear and reappear, inconveniencing both students and faculty and causing huge headaches for the IT staff. "We had a lot of complaints," according to Leo Satara, the IT director at Emmanuel. "There were constant problems, and students complained a lot. We just couldn't manage it or see what was going on."
Because the consumer-grade access points were standalone, they couldn't be uniformly controlled from a central point. That meant that Emmanuel's limited IT staff had to continually troubleshoot the APs on a one-at-a-time basis. Without visibility into the network, IT staff members had to be physically dispatched across the large campus regularly to reset access points that had frozen or hung up.
In addition to fixing coverage and reliability problems, and gaining central control--and all at an affordable price--Emmanuel wanted the higher speeds offered by the coming 802.11n standard, along with its more flexible deployment options.
The 802.11n standard is expected to be ratified in final form in late 2009. However, a number of vendors are already offering 802.11n equipment built to the latest draft version of the standard, on the assumption that little will change between now and final approval. Also, many notebook computers offer 802.11n capabilities already; for those that don't, 802.11n access points can "step down" to accommodate other wireless standards on devices, such as the common 802.11g standard.
After weighing its needs, Emmanuel selected Ruckus Wireless ZoneFlex 802.11n in mid-summer for its wireless solution, choosing a scaled-down version of the original bid in order to focus primarily on residence halls initially. "The dorms were our first priority," Emmanuel Support Specialist Glenn Toney said. "We [initially] covered the places that we really needed to make sure were covered," he explained, adding that the college plans to purchase additional APs for more coverage as the budget allows.
In August, the college worked with a wireless expert from KOR Systems
