Abstract

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.

Claims

1. A system comprising:

a mobile telephone, 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;

wherein low radiation handset includes a low radiation (LR) wireless communicator including a user interface; and

wherein the cellular unit includes a high radiation (HR) wireless communicator including a high power cellular network communication circuit;

wherein;

the LR and HR wireless communicators are adapted to physically couple together for conventional use as a mobile telephone;

the LR and HR wireless communicators are adapted to be physically separated and still allow use of the mobile telephone to make calls on a cellular network, wherein the HR wireless communicator relays communications signals between the LR wireless communicator and the cellular network, and a first communication power level between the LR and HR wireless communicators is lower than a second communication power level between the HR wireless communicator and the cellular network to reduce radiation exposure to a user; and

the HR wireless communicator is operable to sense that the HR wireless communicator is separated from the LR wireless communicator; 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 during voice communication over the WiFi network, a user of the mobile telephone is not exposed to higher radiation levels used to communicate directly with a cellular tower.

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 low radiation handset is a mobile telephone in a low radiation mode of operation.

4. The system of claim 3 wherein the mobile telephone is adapted to detect the presence of the cellular unit.

5. The system of claim 4 wherein the mobile telephone is adapted to automatically switch to a low radiation mode after detecting the presence of the cellular unit.

6. The system of claim 1 wherein the low radiation handset and the cellular unit are adapted to communicate with each other via WiFi.

7. The system of claim 1 wherein the cellular unit is adapted to couple to a wireless router.

8. The system of claim 1 wherein the cellular unit employs a maximum electromagnetic radiation power level greater than permissible for a mobile telephone.

9. The system of claim 1 wherein the HR wireless communicator is operable to automatically increase the second communication power level to a third communication power level in response to the HR wireless communicator sensing that the HR wireless communicator is separated from the LR wireless communicator.

10. The system of claim 9 wherein:

the first communication power level of the LR wireless communicator is provided by a first power supply that includes a battery; and

the second communication power level of the HR wireless communicator is provided by a second power supply.

11. The system of claim 1 wherein the LR and HR wireless communicators are further adapted to allow a user to make calls on a cellular network when separated without exposing the user to radiation levels of a conventional mobile telephone.

12. The system of claim 1 wherein the LR wireless communicator does not include a cellular network communication circuit.

13. The system of claim 1 wherein the HR wireless communicator does not include a user interface.

14. The system of claim 1 wherein the HR wireless communicator is operable at the second communication power level when physically coupled to the LR wireless communicator.

15. The system of claim 12 wherein the HR wireless communicator switches to the second communication power level automatically when the HR wireless communicator is physically coupled to the LR wireless communicator.

16. The system of claim 1 wherein the LR wireless communicator is adapted to communicate with the HR wireless communicator via a wireless router.

17. The system of claim 9 wherein the third communication power level is greater than a maximum electromagnetic radiation power level permissible for a cellular telephone.

18. A system comprising:

a mobile telephone; 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;

during voice communication over the WiFi network, a user of the mobile telephone is not exposed to higher radiation levels used to communicate directly with a cellular tower;

the mobile telephone comprises;

a low radiation (LR) wireless communicator including a user interface, and

high radiation (HR) wireless communicator including a high power cellular network communication circuit;

the LR and HR wireless communicators are adapted to physically couple together for conventional use as a mobile telephone;

the LR and HR wireless communicators are adapted to be physically separated and still allow use of the mobile telephone to make calls on a cellular network, wherein the HR wireless communicator relays communications signals between the LR wireless communicator and the cellular network, and a first communication power level between the LR and HR wireless communicators is lower than a second communication power level between the HR wireless communicator and the cellular network to reduce radiation exposure to a user;

the HR wireless communicator is operable to sense that the HR wireless communicator is separated from the LR wireless communicator;

the HR wireless communicator is operable to automatically increase the second communication power level to a third communication power level when the HR wireless communicator senses that the HR wireless communicator is separated from the LR wireless communicator;

the first communication power level of the LR wireless communicator is provided by a first power supply that includes a battery; and

the second communication power level of the HR wireless communicator is provided by a second power supply.
