Patent ID: 8675715

Claim:
A wideband (WB) communication modem comprising: an interface configured to transceive data in connection with a host device; a baseband processor configured to process, in a parallel manner, a baseband signal being transceived between the interface and a converter; the converter configured to combine an input parallel signal into an output serial signal upon receiving the input parallel signal and output the output serial signal, and to separate an input serial signal into an output parallel signal upon receiving the input serial signal and output the output parallel signal; a radio frequency (RF) processor configured to reduce a frequency of a received WB signal and transmit the frequency-reduced signal to the converter, and increase a frequency of the output serial signal received from the converter and transmit the frequency-increased signal to a directional antenna; and the directional antenna configured to transceive a wireless signal by forming a fixed-type directional beam and control a direction of the fixed-type directional beam to communicate with a target device by fixing the direction of the fixed-type directional beam, wherein a directional beam generator sets a beam angle for transmission to be relatively smaller than a beam angle for reception, wherein the communication modem comprises a first communication system and a second communication system, and the first communication system comprises at least one component among the baseband processor, the converter, and the RF processor, and the second communication system comprises at least one component not present in the first communication system among the baseband processor, the converter, and the RF processor, and the first communication system and the second communication system are disposed to be in separate enclosures interconnected by a connection line, wherein the directional antenna comprises: an antenna pole configured to comprise with the phrase “the directional beam generator which is further configured to output the directional beam”, the second communication system, and a rotation unit mounted with the directional beam generator, the rotation unit configured to be rotated by about 360 degrees; and a joint configured to connect the antenna pole with the first communication system and perform 2-axis rotation about the first communication system.
