Features and Benefits
The SPEEDLAN shelfmount products are high performance 11 MB wireless bridges that create
interconnectivity between buildings and provide an alternative to Telco leased and fiber optic lines.
The SPEEDLAN shelfmount bridges present unparalleled performance and features for any
organization needing high-speed connectivity between enterprise LAN-to-LAN applications such as
school or campus network connections, banking, manufacturing, hospitals and clinics. This enables
a central Ethernet LAN to be connected with one or more branch office LANs up to 25 miles apart.
The SPEEDLAN bridges present a significant breakthrough in LAN connectivity by offering these high
performance bridges that outperform other wireless spread spectrum systems in the industry. These
bridges contain full remote SNMP management and security in an affordable package. This enables
you to monitor a number of SPEEDLAN parameters including RF-signal quality and noise level, as
well as transparent bridging with advanced filtering for security and network reliability.
The central base station and CPE are mounted inside the building and connect to the outdoor
antenna using up to 200 feet of low loss RF antenna cable.
Transparent Ethernet Bridging with Advanced Filtering for Security and
Network Reliability
SPEEDLAN brouters support what is known as Transparent Ethernet Bridging with no Spanning Tree
or Source Routing support. Since the SPEEDLAN brouters provide network security between a local
LAN and a campus or enterprise wide network, and since using multiple bridges in a Spanning Tree
could compromise this security, the Spanning Tree scenario is not supported. In addition, the
SPEEDLAN brouters can filter packets based on protocol type or MAC address pairings. These
features can add a significant measure of security and network reliability to a network
interconnection.
