1. to provide on/off switches to WiFi routers;
2. to establish a protocol of use that
(i) WiFi routers and WiFi/3G functions of computers/laptops/tablets are to be turned on only when they are needed for access to the Internet via the wireless network; and,
(ii) Bluetooth function is to be turned on only if it is needed for accessing other Bluetooth-enabled devices.
3. to observe safety warnings and follow safety instructions in the user manual of iPad by reducing the duration of use under wireless mode and keeping the iPads away from the students’ bodies.
Note that putting an iPad on airplane mode will initially turn off all antennas on the iPad. However, WiFi and bluetooth antennas can be re-enabled without switching off the airplane mode. Therefore, an iPad showing airplane mode “on” is not a guarantee that all the antennas are off. It is important to check the antennas separately. In addition, when the WiFi function on an iPad shows “Not Connected,” it does not mean the antenna is off. It only means the iPad is not logged onto any available wireless network. To ensure the WiFi antenna is turned off, the WiFi function must read “off.”
