Periodic Notification of NAV using Leaky Coaxial Cable for Establishment of Virtual Private Channel in WLAN System

Abstract (in Japanese) (See Japanese page) 
(in English) To establish the private channel for area owner's wireless local area network (WLAN) systems, periodic medium reservation scheme has been proposed. In the scheme, guard stations spatially distributed in the private space send network allocation vector (NAV) frames periodically. Periodic NAV frames notify the medium reservation period to the visitor's BSS (Basic Service Set), and the visitor's BSSs that hear NAV frames defer the access to the medium. However, because of the vulnerable and unpredictable propagation of wireless signal, the transmitted NAV frames propagates throughout the private space and spills over to the outside of the private space. Excessive propagation of NAV frames will interfere third-party BSSs existing outside the private space. As a countermeasure against this problem, this paper proposes a new NAV frame transmission scheme using Leaky Coaxial (LCX) cable. In the proposed scheme, the NAV frames are transmitted through LCX cables installed in the private space. Since the propagation area of NAV frames is finely controlled by LCX, the resource reservation period can be notified everywhere in the private space without interfering the transmission of third-party BSSs existing outside the private space. Numerical results confirm that the proposed scheme enhances the transmission performance of third-party BSSs existing outside space while suppressing the transmission from visitor's BSS existing inside the private space.
