Abstract

Various embodiments are described that relate to directing of a signal. An incoming signal can be compared to a threshold voltage. If the signal does not meet the threshold voltage, then the signal can be used for normal usage, such as communication with a software-defined radio. However, if the signal does meet the threshold, then the signal can be directed away from normal usage. In one example, the signal can be directed away from a communication component and directed to an energy harvesting component that charges a battery of the software-defined radio.

Claims

1. A system, comprising:

a comparison component configured to compare an incoming signal level of an incoming signal against a threshold level; and

a direction component configured to direct the incoming signal away from a communication component when the incoming signal level meets the threshold,

where the comparison component, the direction component, or a combination thereof is implemented, at least in part, by way of hardware.

2. The system of claim 1, comprising:

the communication component that is configured to obtain the incoming signal,

where the direction component is configured to direct the incoming signal toward the communication component when the incoming signal level does not meet the threshold and

where the communication component processes the incoming signal after the incoming signal is directed to the communication component.

3. The system of claim 2, comprising:

a power capture component configured to produce usable energy from the incoming signal,

where the direction component is configured to direct the incoming signal away from the communication component and toward the power capture component when the incoming signal level meets the threshold.

4. The system of claim 1, comprising:

a management component configured to disable transmission of the communication component when the incoming signal level meets the threshold.

5. The system of claim 1, comprising:

an antenna configured to receive the incoming signal that is then accessed by the comparison component;

an identification component configured to determine a frequency band of the incoming signal; and

a tuner component configured to tune the antenna to the frequency band,

where the incoming signal is within a radio frequency range.

6. The system of claim 5, comprising:

a housing that retains the comparison component, the direction component, the antenna, the identification component, and the tuner component; and

a position component configured to determine a location of the housing,

where the identification component is configured to determine the frequency band of the incoming signal thorough determination of a base station that services the location and

where the housing retains the position component.

7. The system of claim 1, comprising:

an identification component configured to identify a transmission request; and

an override component configured to cause the incoming signal to be directed to the communication component when the incoming signal level meets the threshold and when the transmission request is identified such that the direction component does not direct the incoming signal away from the communication component when the incoming signal level meets the threshold.

8. A system, comprising:

a mobile communication device, comprising;

an antenna set to communicate a radio frequency signal;

energy storage hardware configured to provide operational energy to the mobile communication device by way of the radio frequency signal;

communication processor hardware configured to cause the mobile communication device to transmit and to process the radio frequency signal; and

charger hardware configured to charge the energy storage hardware; and

a component set that is resident upon the mobile communication device, the component set comprising;

a charger direction component configured to direct the radio frequency signal, when obtained, away from the communication processor hardware and toward the charger hardware when a signal level of the radio frequency signal meets a voltage threshold; and

a communication direction component configured to direct the radio frequency signal, when obtained, toward the communication processor hardware and away from the charger hardware when the signal level of the radio frequency signal does not meet the voltage threshold.

9. The system of claim 8, the component set comprising:

an output component configured to cause output of a notice when the signal level meets the voltage threshold,

where the notice indicates, when the signal level meets the threshold, that reception of the radio frequency signal is not available.

where the mobile communication device is configured to attempt transmission despite reception of the radio frequency signal not being available,

where the notice is presented upon a display of the mobile communication device, and

where the mobile communication device is a software-defined radio.

17. The method of claim 16, comprising:

determining an actual frequency band of the location;

contrasting the actual frequency band against the database radio frequency band entry such that a contrast result is produced; and

updating the database radio frequency band entry to reflect the actual frequency band when the contrast result indicates a discrepancy between the actual frequency band and the pre-update database radio frequency band entry.
