The latest RRC wrinkle now takes advantage of a radio’s serial port (CAT) similar radio at the remote site. The radios communicate with each other with the help of the RRC unit. This means that all functions of Radio 2 at the remote (i.e., antenna) site, just as if the entire st...
a return message to the gateway could include other information. Examples are: what the signal strength was of the received instruction, how many times radio20had to be paged before it sent a confirm back to the gateway, the identity of the switch that the antenna connected to, and status ...
switches 80 and 81 in order to actuate the transmitting circuitry to transmit a signal from antenna 82, which is received by antenna 84 of receiving device 78. Receiving device 78 is mounted in the vehicle, such as in the vehicle trunk compartment, and includes an output 86 in order to ...

Based on the Bluetooth (registered trademark) technology, for example, the wireless module 753 emits, from the antenna 754, a radio signal indicative of the operation information by using a carrier wave having a predetermined frequency. Thus, the key data from the operation section 72, the ...
The base antenna 509 radiates the base-CDMA signal at the first carrier frequency. As illustratively shown in FIG. 6, a remote unit includes a remote antenna 511, remote-detection means, remote-spreading means, remote-combiner means, and remote-transmitter means. Each remote unit also may ...
