Wireless Classrooms
Educators can use handheld devices with mobile Internet access to improve teaching and learning in both local and wide area network environments.
Local area wireless access.
Using handheld devices equipped with the appropriate software and connected by a wireless network to the Internet exposes students to a rich variety of Web resources that can help them learn various concepts and subjects.
Wide area wireless access.
Teacher training places a heavy emphasis on integrating technology with instruction and learning, yet the reality of inadequate school facilities often dismays instructors.
Mobile computing technology provides the functionality of a desktop PC to teachers who are displaced from their room.
Retailing and Small-Amount Transactions
Cell phones are able to handle any number of purchases made on the fly: movie tickets, soft drinks, or Happy Meals.
The vending machine will be equipped either with the radio portion of a cell phone so that it can receive the call, or with a transceiver that works using Bluetooth, a wireless connection that allows high-speed communication among devices within a short distance of one another.
The machine will then offer you a menu. You'll choose, say, a Diet Pepsi for 75 cents and enter a PIN, and out will tumble your soft drink.
