PURPOSE: A method for doing stable laser network transmitting business through wireless LAN duplexing is provided to adopt a wireless LAN transmitting system with duplexing networks by considering a situation when a laser transmitting network is down, thereby securing a stable transmitting state for subscribers by network duplexing. CONSTITUTION: A high-capacity of transmission is rent with trunk units in connection with an Internet network(1) from a provider of the Internet network(1). A self POP(Point of Presence)(2) transmits transmission capacities, which a distribution hub station(4) requests to subscribers, to a mother base station from each laser hub station(4). A transmission is performed through an optical transmission line up to the mother base station of the hub station(4) from the POP(2). The hub station(4) transmits more than 100 BASE-T capacities through a laser transmission path(6) using a laser module and device(8). When a laser network fails, more than 10 BASE-T capacities are transmitted through a wireless LAN transmission path(5). If a failure processing is normally performed on the laser transmission path(6), the transmission is performed on the wireless LAN transmission path(5) by using the laser module and device(8) again.
