Method and apparatus of wireless communication by using multiple directional antennas

摘要

The present invention relates to an apparatus and method of performing wireless communication using multiple directional antennas. The transportation means according to the present invention includes at least two communication devices, wherein one of the at least two communication devices, communication device A, includes a directional antenna group 1, and the other communication device, communication device B, includes a directional antenna group 2, and wherein the communication device A performs directional antenna selection control of the directional antenna group 1 included in the communication device A depending on whether the communication device B is connected with a network. According to the present invention, one of the communication devices gains access to a satellite station, a base station, or other ships, at least one antenna of another communication device may be used to relay wireless communication and may play a role as a base station or an AP.

主权项

1. A transportation means including a first communication device including multiple directional antennas, and a second communication device, the first communication device comprising:
a received signal strength measuring unit measuring a received signal strength of each of the multiple directional antennas to generate measured received signal strengths; a network communication determination unit determining whether the first communication device is connected to a network to generate connection status information of whether the first communication device is connected to the network; an antenna selecting unit generating an antenna selection signal based on the measured received signal strengths received from the received signal strength measuring unit and connection status information received from a network communication determination unit of the second communication device; and an antenna switch performing connection control between at least one of the multiple directional antennas and a communication unit based on the antenna selection signal received from the antenna selecting unit.
