iPass added the Cloud, Swisscom, to Cross 50,000 hotspot boundary: It's not clear how many hotspots there are in the world above the somewhat formally counted and enumerated 100,000 that JiWire has in their database. But it's clear that iPass having 50,000 locations in its aggregated network that it resells to corporate clients gives it about half of all the professionally operated, purposely public and persistent hotspots on the planet.
The Cloud has been aggressively reselling its network to others, and their 6,000 locations are scattered across the UK. While it started in pubs and cafes, they now cover hotels, conference centers, and airports, and have nine city-centre/center projects going life in the next several months. Swisscom has 1,000 locations in Switzerland, including major rail stations, airports, and hotels.
iPass charges per minute fees (often with maximum per-day caps) for access via dial-up, wired connections, and Wi-Fi. They aggregate usage across a company so that many traveling users don't each need their own account, but can use corporate logins and corporate security policies for their data and their connections while they travel.
