Abstract

A universal multi-band (5 bands or more) RF remote control unit using Bluetooth radio module (a low cost device operating at 2.4 GHz) as the base. It is a keyless, transportable, and low cost unit which can replace most of the conventional individual, in-compatible remote control units with a single universal unit.

Claims

1. A universal multi-band keyless, transportable RF remote control unit using bluetooth radio module as the base comprising mainly CPU, at least one transmitter section, at least one receiver section, at least one interface bus, at least one antenna, and at least one RAM, one ROM, and one EEPROM, wherein the remote control unit is connected to a personal communication device through the interface bus.

2. The universal multi-band keyless, transportable RF remote control unit using bluetooth radio module as the base as claimed in claim 1, wherein there are two transmitter sections, one of them including a phase detector, a low pass filter, a first frequency divider, a first rf amplifier, and a vco (voltage-controlled oscillator);

and another of them including a second frequency divider and a second rf amplifier.
