WiFi allows access to the Internet through wireless access points like the ones at Dana Hall and in many homes. WiFi 3G and WiFi 4G allow additional access to the Internet in places where WiFi is not available but a cellular signal from AT&T or Verizon is available (e.g., on the bus ride to and from an away game). In order to take advantage of this functionality, a carrier and a monthly data plan must be specified at the time of iPad purchase. However, unlike with a cell phone, a contract is not required and the cellular data plan can be turned on or off from month to month. WiFi meets Dana Hall 's requirements and students will not be required to have 3G or 4G access.
