PRO 11 SERIES WIRELESS ETHERNET
1.3.4 W
ORKGROUP
The Workgroup Bridge is a high-speed, wide-range wireless LAN bridge that
provides connectivity to remote Ethernet networks.
The Workgroup Bridge communicates with the Access Points of the remote LANs,
effectively creating an extended wireless network spanning sites situated up to 6
miles (9.7 km) apart (in Europe, this range is limited by ETSI regulations to 2.5
km; in deregulated regions, this range can be up to 60 km). In this way a central
Ethernet LAN may be connected with one or more branch-office LANs.
In addition, an island consisting of a Workgroup Bridge together with an Access
Point can work as a relay. Transmissions from the central LAN and from the
remote LAN are relayed via the island located between them. This configuration
effectively doubles bridge range.
Workstations that can be connected to the wireless LAN include PCs, X-Terminals,
and any other device that supports Ethernet. The unit is transparent to the
workgroup devices' hardware, software, and network operating system.
The Workgroup Bridge contains an embedded SNMP agent and software
downloading capabilities enabling effective management. Software upgrades are
downloaded using TFTP protocol via the Ethernet ports or via the wireless LAN
and Access Point.
The Workgroup Bridge is available in two models:
• With two integrated 2-dBi omnidirectional antennas (LW0053A).
• With two external-antenna connector ports (LW0058A or LW0063A-CAN).
1.3.5 PCMCIA A
DAPTER
The PCMCIA Adapter gives the portable computer user continuous connectivity
and complete mobility, allowing seamless roaming throughout the wireless LAN
campus. It converts any portable computer (including notebooks, laptops, pen-
based and hand-held computers) containing a PCMCIA Release 2.1 Type II slot
into a wireless LAN workstation.
The PCMCIA Adapter can communicate with any other wireless station in its cell
coverage area. Furthermore, any two wireless stations in two different cells can
communicate through their Access Points. The PCMCIA Adapter can access all
network resources, such as file servers, other wired stations, printers, and shared
databases, via the Access Point.
