Abstract

A portable antenna control device includes: a main controller for generating a control signal for adjusting a device provided in an antenna; a modem unit for converting the control signal generated by the main controller into an on-off keying (OOK) signal; a power management unit for supplying direct current power; and an OOK port for synthesizing and outputting the OOK signal converted by the modem unit and the direct current power supplied by the power management unit.

First claim

What is claimed is:

1. A portable antenna control device, comprising:
a main controller configured to generate a control signal for adjusting a device in an antenna;
a modem configured to convert the control signal generated by the main controller directly into an on-off keying (OOK) signal and to directly transmit the OOK signal to a communication port which is provided in the portable antenna control device;
the communication port configured to receive the OOK signal from the modem, and to transmit the OOK signal externally to an antenna system through a radio frequency (RF) feeder cable; and
a battery configured to supply power to the main controller and the modem; and
a case which physically encloses the main controller, the modem, the communication port, and the battery,
wherein the communication port is further configured to provide direct current (DC) power to the antenna system through the RF feeder cable.

2. The portable antenna control device of claim 1 , further comprising:
a power management unit configured to manage the battery to supply the power to the main controller and the modem.

3. The portable antenna control device of claim 1 , wherein the control signal generated by the main controller is a transistor-transistor logic (TTL) signal.

4. The portable antenna control device of claim 1 , wherein the device provided in the antenna is at least one of a remote electrical tilt (RET) equipment for adjusting an electronic down tilt angle, a remote azimuth steering (RAS) equipment for adjusting azimuth steering, and a remote azimuth beamwidth (RAB) equipment for adjusting an azimuth beamwidth.

5. The portable antenna control device of claim 1 , further comprising:
an RS-485 converter for converting another control signal generated by the main controller into an RS-485 signal; and
an RS-485 port for outputting the RS-485 signal converted by the RS-485 converter.

6. The portable antenna control device of claim 1 , further comprising:
an RS-232 converter for converting another control signal generated by the main controller into an RS-232 signal; and
an RS-232 port for outputting the RS-232 signal converted by the RS-232 converter.

7. The portable antenna control device of claim 1 , wherein the device provided in the antenna is at least one of a remote electrical tilt (RET) equipment for adjusting an electronic down tilt angle, a remote azimuth steering (RAS) equipment for adjusting azimuth steering, and a remote azimuth beamwidth (RAB) equipment for adjusting an azimuth beamwidth.

8. The portable antenna control device of claim 1 , further comprising:
a low pass filter (LPF) provided between the modem and the communication port and filtering and passing a band of the OOK signal converted by the modem.

9. The portable antenna control device of claim 1 , further comprising:
a battery charge controller for charging the battery with a DC voltage supplied from an external AC/DC adapter.

10. The portable antenna control device of claim 1 , wherein the modem does not generate an RS-485 signal in a process of converting the control signal into the on-off keying (OOK) signal.

11. The portable antenna control device of claim 1 , wherein the modem is configured to convert the control signal in a transistor-transistor logic (TTL) format to an Antenna Interface Standards Group (AISG) format.
