WiFi, also known as 802.11b, uses radio waves to send information at speeds of up to 11 megabits per second over a range of up to 300 feet. When combined with a Wireless Access Point or Wireless Router, it provides users with wireless high-speed internet access.
Most WiFi users access the internet through home or work networks. In addition, there are over 24,000 WiFi Hot Spots worldwide in cafes, airports, and hotels. Some provide free access, most charge a fee.
An example of one the larger fee-based Hot Spot services in the US is T-Mobile HotSpot . It provides over 2,000 locations in Starbucks, Borders bookstores, and airline clubs. It offers a variety of payment plans, like pay as you go, prepay, and annual contracts. I utilize this service to pick up email when travelling on business since I almost always can find a Starbucks or Borders nearby. |
