802.11n wireless LAN tests show 'unbelievable' results at state college

The IT staff at Morrisville State College, where the first large-scale Draft 802.11n wireless LAN is being designed, says the beta gear exceeds expectations. The school last week plugged in the first 10 production units of Meru Networks access points.

One issue still facing the college, however, is when and how to upgrade the electrical system for the high-throughput devices, 900 of which will eventually be deployed across campus

The New York college, near the state’s rural center, is in the final stage of building a pervasive campuswide WLAN based initially on Meru Networks’ existing 802.11a/b/g access points. Those will start to be replaced this month and next with the newest Meru access points, which have a chipset that supports 11n. The first ten of these were shipped to the college last week.

With 11n, users can expect to see throughput of 100M to 300Mbps, depending on how the access point and client adapter are configured. That compares with 20M to 25Mbps today for 11a and 11g WLANs. In addition, users can expect to see high throughput sustained over longer distances from 11n access points. In tests that began in June, Morrisville network administrators are finding that 11n is delivering on its promise.

“Some of the statistics [from the tests] were just unbelievable,” says Jean Boland, vice president of technology services for the college,  in Morrisville, N.Y. “[In general,] speeds were five times that of 11g.” Often, they were higher: According to Boland, a 50MB file uploaded from a laptop to a network drive took 3 minutes, 51 seconds with an 11g connection, but 26 seconds with an 11n connection -- nearly nine times faster.
