Abstract

A system includes a location information-providing device and a two-way radio handheld transceiver. The location information-providing device is operable so as to transmit a location signal, which contains predetermined location information that is associated with an installed location thereof and that is stored therein, wirelessly. The two-way radio handheld transceiver is operable so as to receive the location signal transmitted by the location information-providing device, so as to store therein the predetermined location information contained in the location signal received thereby, and so as to transmit the predetermined location information stored therein wirelessly.

Claims

1. A system, comprising:

at least one location information-providing device storing therein predetermined location information associated with an installed location thereof, and operable so as to generate a location signal, which contains the predetermined location information stored therein, and so as to transmit the location signal generated thereby wirelessly; and

a two-way radio handheld transceiver operable so as to receive the location signal transmitted by said location information-providing device, so as to store therein the predetermined location information contained in the location signal received thereby, and so as to transmit the predetermined location information stored therein wirelessly.

2. The system as claimed in claim 1, wherein said location information-providing device is further operable so as to detect a condition of the surroundings thereof, and the location signal generated thereby further contains the condition of the surroundings detected thereby,

said two-way radio handheld transceiver being further operable so as to transmit the condition of the surroundings contained in the location signal received thereby wirelessly.

3. The system as claimed in claim 1, wherein said location information-providing device generates and transmits the location signal automatically.

4. The system as claimed in claim 1, wherein said two-way radio handheld transceiver is further operable so as to send a location request to said location information-providing device, and said location information-providing device generates and transmits the location signal in response to the location request from said two-way radio handheld transceiver.

5. The system as claimed in claim 4, wherein said two-way radio handheld transceiver is adapted to receive a global positioning system (GPS) signal, and is further operable so as to generate location information thereof based on the GPS signal received thereby, and so as to transmit the location information generated thereby wirelessly.

6. The system as claimed in claim 5, wherein said two-way radio handheld transceiver is further operable in a location-transmitting mode, where said two-way radio handheld transceiver determines a quality of the GPS signal received thereby such that said two-way radio handheld transceiver transmits the location information generated thereby when it is determined that the quality of the GPS signal received thereby exceeds a predetermined threshold, and such that said two-way radio handheld transceiver sends the location request to said location information-providing device when it is determined that the quality of the GPS signal received thereby does not exceed the predetermined threshold.

7. The system as claimed in claim 6, further comprising a locating device operable so as to receive the location information of said two-way radio handheld transceiver and the predetermined location information transmitted by said two-way radio handheld transceiver and so as to send a location request to said two-way radio handheld transceiver,

said two-way radio handheld transceiver operating in the location-transmitting mode in response to the location request from said locating device.

8. A location information-providing device, comprising:

a memory unit storing therein predetermined location information associated with an installed location of said location information-providing device;

a processing unit coupled to said memory unit, and operable so as to generate a location signal, which contains the predetermined location information stored in said memory unit; and

a transceiver unit coupled to said processing unit, and operable so as to transmit the location signal generated by said processing unit wirelessly.

9. The location information-providing device as claimed in claim 8, further comprising a sensor unit coupled to said processing unit, and operable so as to detect a condition of the surroundings of said location information-providing device, and the location signal generated by said processing unit further contains the condition of the surroundings detected by said sensor unit.

10. The location information-providing device system as claimed in claim 8, wherein said processing unit generates and said transceiver unit transmits the location signal automatically.

11. The location information-providing device as claimed in claim 8, wherein said transceiver unit is adapted to receive a location request,

said processing unit generating and said transceiver unit transmitting the location signal in response to the location request received by said transceiver unit.

12. A two-way radio handheld transceiver, comprising:

a receiver module including

a transceiver unit adapted to receive a location signal wirelessly, which contains predetermined location information associated with said two-way radio handheld transceiver,

a processing unit that is coupled to said transceiver unit, and that is operable so as to extract the predetermined location information from the location signal received by said transceiver unit, and

a memory unit that is coupled to said processing unit, and that stores therein the predetermined location information extracted by said processing unit; and

a transceiver module coupled to said receiver module, and operable so as to transmit the predetermined location information stored in said memory unit wirelessly.

13. The two-way radio handheld transceiver as claimed in claim 12, further comprising a positioning module adapted to receive a global positioning system (GPS) signal, and operable so as to generate location information of said two-way radio handheld transceiver based on the GPS signal received thereby,

said transceiver module being further operable so as to transmit the location information generated by said positioning module wirelessly.

14. The two-way radio handheld transceiver as claimed in claim 13, wherein said processing unit is operable in a location-transmitting mode, where said processing unit determines a quality of the GPS signal received by said positioning module such that said transceiver module transmits the location information generated by said positioning module when it is determined that the quality of the GPS signal received by said positioning module exceeds a predetermined threshold, and such that said transceiver unit of said receiver module sends a request for the location signal when it is determined that the quality of the GPS signal received by said positioning module does not exceed the predetermined threshold.

15. The two-way radio handheld transceiver as claimed in claim 12, wherein said transceiver module is one of an analog transceiver module, a digital transceiver module, a half-duplex transceiver module, and a full-duplex transceiver module.
