Aruba thinks it may be part of the creation of the world's largest wireless local area network (WLAN): I'm not quite sure if they're right, but they make a good case. The network will require between 3,000 and 10,000 APs. On the short end of that range, there are plenty of campus-wide (academic and business) networks in that scale. But on the higher end, I'm unaware of anything that large. Even city-wide networks like Philadelphia should employ only the mid-thousands of nodes, although they're not providing the same kind of high-availabily, in-building overage that Ohio State will have.
The stats: 50,000 students, 27,000 faculty/staff, 25 million square feet across 400 buildings, and 1,700 acres. In three weeks, they've lit up 1,700 APs in 28 buildings. I assumed that was the time to get the network running, not both physically stringing APs and logically activating the network--but I'm apparently wrong. Read the comment below. [link via Engadget]
