Description
Wireless LAN uses radio frequencies
to transmit and receive data between PC's or other network devices
without wires or cables. The applications of wireless LAN include
independent networks (suitable for small or temporary peer-to-peer
configurations) and infrastructure networks, offering fully distributed
data connectivity via micro cells and roaming.
The TWL-C11 Wireless LAN PC Card is designed and manufactured by Tellus
Group Corporation --- a company with expertise in wireless communication
sector. Its performance and reliability exceed the requirements of IEEE
802.11b standard, and its interoperability and plug-and-play features
make installation quite easy.
