Additional global findings:
* The US remained the leading Wi-Fi country, accounting for 56 percent of global Wi-Fi usage.
* Sessions in China jumped 164 percent, placing them among the top 20 of all countries for the first time.
The index also revealed that businesspeople are connecting over Wi-Fi for longer periods of time; average daily usage grew 25 percent to 87 minutes, up from 70 minutes in the second half of 2006. While users in the United States recorded an average online time of 90 minutes, users in China and South Korea stayed connected for twice as long, averaging more than three hours online a day.
"These results indicate that business demand for Wi-Fi hotspots has grown from a novelty to a mainstream need," said Joel Wachtler, vice-president of marketing and strategy, iPass. "We are also seeing that use of hotspots is a global phenomenon, with the standard for growth being set in European and Asian countries."
Airports Becoming a Second Office for Frequent Flyers
Wi-Fi has become especially useful for workers looking to make the most of downtime at airports and hotels, which combined, accounted for more than five out of every six sessions globally.
Airports led usage with 56 percent of sessions overall. However, hotels are closing the gap, with a 123 percent increase, accounting for 30 percent of overall sessions.
The iPass Wi-Fi Hotspot Index summarizes session* data collected by iPass across its base of users at more than 3,500 companies around the world. The full study is available at www.ipass.com/wifihotspotindex.
* The term "session" refers to one user logging into a given location one or more times during a single day. The average "session length" is calculated by dividing the total number of minutes spent connected by the total number of day sessions.
