Wireless LAN System Using Leaky Coaxial Cable

摘要

Toshiba TEC is developing a new wireless LAN system using leaky coaxial cable (LCX) as an antenna for the wireless access points. Our target products are broadband wireless LANs specified by IEEE802.11a and 11g. The LCX wireless LAN can maintain high quality of communications in an indoor environment where many obstacles exist. It can also limit the propagation range of radio waves transmitted by access points. These features are realized through the combination of the LCX's unique propagation characteristics and the anti-multipass characteristics of orthogonal frequency division multiplexing (OFDM). The LCX wireless LAN is expected to be a system suitable for future wireless LANs that ensures both mobility and security.
