<p>The present invention relates to an apparatus for measuring a wireless channel. The apparatus receives, from a transmitting party, a packet including a probing signal for measurement and GPS location coordinates, and acquires, from the received packet, a channel signal and transmission GPS coordinate information to convert into a transmission point and a transmission distance, thereby analyzing a propagation distance between two terminals when a wireless link is formed between the two terminals, a direct or relative three-dimensional location and moving speed when a passenger or a vehicle is stopped or moving, and temporal and spatial characteristics of wireless channel parameters, and the apparatus can analyze all influences caused by surroundings including trees, buildings, communication obstacles, etc. by mapping location information and channel characteristics with accurate GIS map data.</p> |
