Title:
TRANSMISSION SYSTEM, RADIO WAVE COMMUNICATION NETWORK AND COMMUNICATION METHOD
Document Type and Number:
Japanese Patent JP3153130
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a cost-effective reverse directional transmission system through the use of a single directional millimeter wave antenna with high gain for communication between a PCS band antenna and a PCS hub.
SOLUTION: A PCS network adds micro cell repeaters 100, 101, 102 and 103, micro cell hubs 104, 105, a base station 110 and a fixed network 120. Radio wave telephone sets 10, 11, 12 and 14 and multi-media work stations 50, 51 transmit/receive information with the corresponding PCS band antennas 20-25 between the most adjacent repeaters 100-103 or the hubs 104, 105. The millimeter wave band antennas 30-33 are the ones such as a parabola antenna, a single directional antenna and a high gain antenna, etc., and form a millimeter wave link between the repeaters 100 and 103 (101 and 102) and the hub 104 (105).
