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.

Wireless LAN Access Point 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. It can be used as a bridge to enable wireless network access
in Ethernet environment or be installed as a repeater to extend the link
distance in peer-to-peer configuration.
