Planning And Installing Wireless Lans; System Configurations; Single-Cell Configuration - Black Box LW0050A Manual

PRO 11 SERIES WIRELESS ETHERNET
5. Planning and Installing
Models LW0050A through LW0054A are equipped with two integrated 2-dBi
omnidirectional antennas and are suitable for indoor, short- to medium-range
installations. Models LW0055A through LW0059A are equipped with two
customized female connectors for use with a range of external antennas.
This chapter describes various possible system configurations, lists points to
consider when performing indoor and outdoor installations, and presents
guidelines and restrictions regarding external antenna installation.

5.1 System Configurations

This chapter describes various wireless LAN configurations and how to set them
up:
• Single-Cell Configuration – The wireless LAN consists of an Access Point and
the wireless workstations associated with it.
• Overlapping-Cell Configuration – The wireless LAN consists of two or more
adjacent Access Points whose coverage slightly overlaps.
• Multicell Configuration – The wireless LAN consists of several Access Points
installed in the same location. This creates a common coverage area that
increases aggregate throughput.
• Multi-Hop Configuration – The wireless LAN contains Access Point-
Workgroup Bridge pairs that extend the range of the wireless LAN.
Many wireless LANs contain several of these configurations at different points in
the system. The Single-Cell configuration is the most basic, and the other
configurations build upon it.

A basic cell consists of an Access Point and the wireless workstations associated with
it. You can convert most workstations (for example, PCs and X-Terminals) that are
equipped with an Ethernet network interface card (NIC) to wireless workstations
simply by connecting a Station Adapter. You can convert most laptop computers
with a PCMCIA slot into wireless mobile stations by using the PCMCIA Adapter
(LW0054A or LW0059A).
