While numerous municipalities, including the entire country of Singapore, are moving forward with far-reaching Wi-Fi access plans, Aruba Wireless Network’s “Mobile Edge solution” will be the most expansive WLAN by the time it is complete. Although the installation is only partially finished, 1,700 access points in over 28 buildings have already been lit, and Ohio State’s IT department has plans to cover all 25 million square feet of the main campus with WiFi.

Once complete, over 77,000 students and staff will have “ubiquitous wireless access to the university’s networks” thanks to the “nearly 10,000″ APs that will beam 802.11a/b/g all across OSU. Although the entire rollout won’t be finalized until 2011, the 31 Buckeye residence halls will supposedly get blanketed within the next month.Via Engadget
