Abstract

A system for providing a wireless connection from a cell site to its own operations and maintenance panel (OMP). A unit is built into a cell site on the radio shelf that includes features of a cellular telephone. Such unit includes a modem so that a laptop or other type of computer may be plugged in. This system operates in a plurality of mobile modes--so that it can communicate with any or all of the wireless telecommunication system types (such as AMPS, TDMA, CDMA), and frequency ranges (i.e., 850 MHZ and microwave)--and a diagnostic mode. While the system is installed, the wireless telephone unit is in the mobile mode and can communicate with another type of wireless system. However, once the system comes on line, the unit can communicate with other cell sites in the area from its own system, thus reducing the cost of maintenance. Furthermore, such a system can be used for informing the OMP of alarms such as an intruder alarm, etc. Advantageously, after installation, emergency telephone service or other directly connected telephone service, may be provided by this system. In addition, in the diagnostic mode, diagnostic routines may be run on the system.

Claims

1. A wireless remote office maintenance and administration system for use in installing and maintaining a wireless cell site having an antenna system connected thereto, the system comprising:

a mobile telephone unit having

a control input for receiving control signals for determining whether a mobile mode or a diagnostic mode is implemented,

a plurality of wireless transceivers corresponding to a plurality of wireless system types, each communicating with a different type of wireless telephone during the mobile mode,

a selector for selecting one of said plurality of wireless transceivers for a specific communication function during the mobile mode, and

a multiplexer connected to said plurality of wireless transceivers; and

,

a radio control block connected to the multiplexer and having a first switch and a second switch,

wherein the first switch includes a plurality of ports and the second switch includes a plurality of ports, and

further wherein at least two of the plurality of ports of the first switch are connected to a transmission line of the mobile telephone unit through a first splitter box and at least two of the plurality of ports of the second switch are connected to a receiving line of the mobile telephone unit through a second splitter box.

2. The system as set forth in claim 1 further comprising means to move the system from location to location.

3. The system as set forth in claim 1 wherein the mobile telephone unit connects to the antenna system through the transmission and receiving lines and selected ports.

4. The system as set forth in claim 3 wherein the mobile telephone unit connects to a second antenna through the antenna system.

5. A wireless remote office maintenance and administration system for use in installing and maintaining a wireless cell site having an antenna system for an antenna connected thereto, the system comprising:

a mobile telephone unit having

a control input for receiving control signals for determining whether a mobile mode or a diagnostic mode is implemented,

a plurality of wireless transceiver means, each communicating with a different type of wireless telephone during the mobile mode,

a selector means for selecting one of said plurality of wireless transceiver means for a specific communication function during the mobile mode, and

multiplexer means connected to said plurality of wireless transceiver means; and

,

a radio frequency switch device.

6. The system as set forth in claim 5 further comprising means to move the system from location to location.

7. The system as set forth in claim 5 wherein the radio frequency switch device connects to the multiplexer means and includes a first switch and a second switch.

8. The system as set forth in claim 7 wherein the first switch includes a plurality of ports and the second switch includes a plurality of ports.

9. The system as set forth in claim 8 wherein at least two of the plurality of ports of the first switch are connected to a transmission line through a first splitter box and at least two of the plurality of ports of the second switch are connected to a receiving line through a second splitter box.

10. The system as set forth in claim 9 wherein the transmission line and receiving line connect to the multiplexer means of the mobile telephone unit.

11. The system as set forth in claim 10 wherein the mobile telephone unit connects to the antenna system through the transmission and receiving lines amd selected ports.

12. The system as set forth in claim 11 wherein the mobile telephone unit connects to a second antenna through the antenna system.

13. A wireless cell site system including a wireless cell site having an antenna system for an antenna and a remote control center, the system comprising:

a means for conveying the wireless cell site from location to location;

a first mobile telephone unit disposed within the cell site having

a control input for receiving control signals for determining whether a mobile mode or a diagnostic mode is implemented,

a plurality of wireless transceivers corresponding to a plurality of channels, each communicating with a different type of wireless telephone during the mobile mode,

a selector for selecting one of said plurality of wireless transceivers for a specific communication function during the mobile mode, and

a multiplexer connected to said plurality of wireless transceivers;

a radio control block connected to the multiplexer and disposed within the cell site;

a plurality of second mobile telephone units positioned to communicate with the cell site; and

,

a means for establishing a wireless data link between the cell site and the remote control center.

14. The system as set forth in claim 13 wherein the plurality of second mobile telephone units communicate with each other through the cell site.

15. The system as set forth in claim 13 wherein the radio control block includes a first switch and a second switch.

16. The system as set forth in claim 15 wherein the first switch includes a plurality of ports and the second switch includes a plurality of ports.

17. The system as set forth in claim 16 wherein at least two of the plurality of ports of the first switch are connected to a transmission line through a first splitter box and at least two of the plurality of ports of the second switch are connected to a receiving line through a second splitter box.

18. The system as set forth in claim 17 wherein the transmission line and receiving line connect to the multiplexer of the first mobile telephone unit.

19. The system as set forth in claim 18 wherein the first mobile telephone unit connects to the antenna system through the transmission and receiving lines and selected ports.

20. The system as set forth in claim 19 wherein the first mobile telephone unit connects to a second antenna through the antenna system.
