Cisco Wireless LAN Solution Product Guide

Chapter 1 Overview
Lightweight Access Points
Figure 1-10 1000 Series Lightweight Access Points
The Cisco WLAN Solution also offers 802.11a/b/g Cisco 1030 Remote Edge Lightweight Access Points,
which are Cisco 1000 series lightweight access points designed for remote deployment, Radio Resource
Management (RRM) control via a WAN link, and which include connectors for external antennas.
The Cisco 1000 series lightweight access point is manufactured in a neutral color so it blends into most
environments (but can be painted), contains pairs of high-gain internal antennas for unidirectional
(180-degree) or omnidirectional (360-degree) coverage, and is plenum-rated for installations in hanging
ceiling spaces.
In the Cisco Wireless LAN Solution, most of the processing responsibility is removed from traditional
SOHO (small office, home office) access points and resides in the Cisco Wireless LAN Controller.
Cisco 1030 Remote Edge Lightweight Access Points
The only exception to the general rule of lightweight access points being continuously controlled by
Cisco Wireless LAN Controllers is the Cisco 1030 IEEE 802.11a/b/g remote edge lightweight access
point (Cisco 1030 remote edge lightweight access point). The Cisco 1030 remote edge lightweight
access point is intended to be located at a remote site, initially configured by a Cisco Wireless LAN
Controller, and normally controlled by a Cisco Wireless LAN Controller.
However, because the Cisco 1030 remote edge lightweight access point bridges the client data
(compared with other Cisco 1000 series lightweight access points, which pass all client data through
their respective Cisco Wireless LAN Controller), if the WAN link breaks between the Cisco 1030 remote
edge lightweight access point and its Cisco Wireless LAN Controller, the Cisco 1030 remote edge
lightweight access point continues transmitting wireless LAN 1 client data through other Cisco 1030
remote edge lightweight access points on its local subnet. However, it cannot take advantage of features
accessed from the Cisco Wireless LAN Controller, such as establishing new VLANs, until
communication is reestablished.
