Methods and apparatus for reducing cellular telephone radiation exposure
In some aspects, a cellular telephone includes (1) a user interface portion having a communications circuit; and (2) a cellular portion having a first communications circuit adapted to communicate with the communications circuit of the user interface portion and a second communications circuit adapted to communicate with a cellular network. The cellular portion is removably coupled to the user interface portion so as to allow a user of the cellular telephone to communicate over a cellular network by using the user interface portion while the cellular portion is separated from the user interface portion. Numerous other aspects are provided.
1. A system comprising:
a mobile telephone operative to communicate directly with a cellular network; and
an application executable on the mobile telephone, the application including computer program code operative to direct the mobile telephone to:
detect the presence of a WiFi network; and
in response to detecting the presence of the WiFi network:
switch the mobile telephone to a low radiation mode by communicating using low radiation emitting communications circuitry and a WiFi communications protocol;
stop communicating directly with a cellular network; and
allow voice communication from the mobile telephone over the WiFi network without communicating directly over a cellular network and using a radiation level that is less than is used to communicate directly over a cellular network using the mobile telephone;
wherein a user of the mobile telephone is not exposed to higher radiation levels used to communicate directly with a cellular tower during voice communication over the WiFi network.
2. The system of claim 1 wherein the application is configured to allow the mobile telephone to allow a user to make voice calls directly through a wireless router.
3. The system of claim 1 wherein the mobile telephone comprises:
a low radiation handset; and
a cellular unit separate from the low radiation handset and adapted to communicate with the low radiation handset and to allow the low radiation handset to communicate over a cellular network.
4. The system of claim 3 wherein the low radiation handset is a mobile telephone in a low radiation mode of operation.
5. The system of claim 4 wherein the mobile telephone is adapted to detect the presence of the cellular unit.
6. The system of claim 5 wherein the mobile telephone is adapted to automatically switch to a low radiation mode after detecting the presence of the cellular unit.
7. The system of claim 3 wherein the low radiation handset and the cellular unit are adapted to communicate with each other via WiFi.
8. The system of claim 3 wherein the cellular unit is adapted to couple to a wireless router.
9. The system of claim 3 wherein the cellular unit employs a maximum electromagnetic radiation power level greater than permissible for a mobile telephone.
