## Abstract

A mobile handset configured to estimate the radiation absorbed per mass of tissue of a user, and to perform an action in case the absorbed radiation exceeds a predefined threshold. The absorbed radiation may be estimated during a call. Additionally or alternatively, a prediction of the absorbed radiation level may be estimated and given to the user while the handset is not engaged in a call. various data items such as received power per time, estimated absorbed radiation and location may be transmitted to a server. A server application may use these data items to create regional maps of a cellular network coverage and quality by accumulating multiple inputs from a plurality of individual mobile handsets.

## Claims

### Claim 1

A cellular communication system comprising:
a cellular network ;
at least one mobile handset in active communication with said cellular network, said mobile handset capable of estimating radiation exposure in a user, generating a radiation report, and automatically prompting the user to perform an action, upon the estimation of radiation exposure exceeding a selected amount the action selected from at least one of: direct the call to a wired or wireless headset, direct the call to a speaker, move the mobile handset a distance from the user, disconnect the call, change orientation of the mobile device with respect to the user, provide a guidance indicator to direct the user to orient the mobile handset towards a cellular base-station the user communicates with, move to a location where the mobile handset will radiate less power, switch to vertical phone posture, switch to horizontal phone posture, use a loudspeaker, and move to the previous or a different geographical location; and
further comprising a peer mobile handset and wherein said peer mobile handset is adapted to receive a message from said mobile handset in response to said radiation exposure exceeds a threshold.

### Claim 2

A cellular communication system comprising:
a cellular network;
at least one mobile handset in active communication with said cellular network, said mobile handset capable of estimating radiation exposure in a user, generating a radiation report, and automatically prompting the user to perform an action, upon the estimation of radiation exposure exceeding a selected amount the action selected from at least one of: direct the call to a wired or wireless headset, direct the call to a speaker, move the mobile handset a distance from the user, disconnect the call, change orientation of the mobile device with respect to the user, provide a guidance indicator to direct the user to orient the mobile handset towards a cellular base-station the user communicates with, move to a location where the mobile handset will radiate less power, switch to vertical phone posture, switch to horizontal phone posture, use a loudspeaker, and move to the previous or a different geographical location; and
a monitoring mobile handset to configure and supervise said mobile handset, to receive a message from said mobile handset in response to the radiation exposure exceeds a threshold and to get said radiation report of said mobile handset.

### Claim 3

A cellular communication system comprising:
a cellular network;
at least one mobile handset in active communication with said cellular network, said mobile handset capable of estimating radiation exposure in a user, capable of generating a radiation report, automatically prompting the user to perform an action, upon the estimation of radiation exposure exceeding a selected amount the action selected from at least one of: direct the call to a wired or wireless headset, direct the call to a speaker, move the mobile handset a distance from the user, disconnect the call, change orientation of the mobile device with respect to the user, provide a guidance indicator to direct the user to orient the mobile handset towards a cellular base-station the user communicates with, move to a location where the mobile handset will radiate less power, switch to vertical phone posture, switch to horizontal phone posture, use a loudspeaker, and move to the previous or a different geographical location; and
further comprising a user PC to configure said mobile handset and to get said radiation report of said mobile handset.
