Wireless indoor data relay system
TLDR
In this paper, the authors proposed a wireless optical relay system with IR transmitters, receivers, and narrow beam optics, which removes the requirement of cable interconnections to local area network (LAN) nodes with wireless relay stations suitable for high data rates.Abstract:
This invention removes the requirement of cable interconnections to local area network (LAN) nodes with wireless optical relay stations suitable for high data rates. Relay sections are equipped with IR transmitters, receivers and narrow beam optics. Manual beam alignment during the LAN installation is aided by a visible light beam of equal beam width and direction. Rotational freedom of the optical antenna systems provide precise aiming. Structure couplers extend, by low-power RF coupling through nonmetallic wall and ceilings, the wireless data transmission from a single room to rooms and building floors. Shielding and wall gaskets of the structure couplers eliminate RF radiation penetration and leakage, and therefore prevent eavesdropping and jamming.read more
