Document Type and Number:
WIPO Patent Application WO/2021/010384
Kind Code:
A1
Abstract:
[Problem] To provide a communication system configured using a waveguide antenna that transmits construction site monitoring information, etc., more reliably to a supervisory center, etc., via a simple structure, said system being capable of being attached, detached, and reused. [Solution] The waveguide antenna is configured from a radio wave leakage unit 2 for allowing radio waves to be transmitted to the inside and to leak from a portion of a side wall, and a single-pipe unit 3 for length-adjustably connecting the radio wave leakage unit 2 and an input connector 6 with a single pipe, the input connector 6 being connected to a wireless access point, and a wireless device and a wireless terminal performing wireless communication therebetween via the leaked radio waves among the radio waves transmitted from the wireless access point.
