1. Introduction

1.1. Overview

The IWE1700-A outdoor wireless access point (AP) enables IEEE 802.11b client computers to access

the resources on the Ethernet network. There are 2 model variations, Pro, and Advanced, which are

classified in terms of features. With the sleek Web-based user interface and Windows-based user in-

terface (Wireless Network Manager), a network administrator can easily and clearly manage the AP.

In Chapter 2, we describe the steps to install and configure a newly acquired AP. Following the steps,

the AP can be quickly set up to work. In Chapter 3, detailed explanation of each Web management

page is given for the user to understand how to fine-tune the settings of an AP to meet his or her spe-

cific needs. In addition to using Web-based management user interface to configure an AP, the Win-

dows-based Wireless Network Manager can also be used to configure and monitor deployed APs. See

the on-line help of Wireless Network Manager for more information.

1.2. Features

zIEEE 802.11b

Operational modes

AP/Bridge. This mode provides both Access Point and Static LAN-to-LAN Bridg-

ing functionality. The static LAN-to-LAN bridging function is supported through

Wireless Distribution System (WDS).

AP Client. This mode is for Dynamic LAN-to-LAN Bridging. The AP Client auto-

matically establishes bridge links with APs from any vendors.

64-bit and 128-bit WEP (Wired Equivalent Privacy). For authentication and data

encryption.

Enabling/disabling SSID broadcasts. When the AP is in AP/Bridge mode, the ad-

ministrator can enable or disable the SSID broadcasts functionality for security reasons.

When the SSID broadcasts functionality is disabled, a client computer cannot connect to

the AP with an “any” network name (SSID, Service Set ID); the correct SSID has to be

specified on client computers.

MAC-address-based access control. When the AP is in AP/Bridge mode, it can be

configured to block unauthorized wireless client computers based on MAC (Media Access

Control) addresses. The ACL (Access Control List) can be downloaded from a TFTP

server.

IEEE 802.1x/RADIUS. When the AP is in AP/Bridge mode, it can be configured to au-

thenticate wireless users and distribute encryption keys dynamically by IEEE 802.1x

Port-Based Network Access Control and RADIUS (Remote Authentication Dial-In User

Service).

WPA (Wi-Fi Protected Access). The AP supports the WPA standard proposed by the

Wi-Fi Alliance (http://www.wi-fi.org). Both WPA-PSK (Pre-Shared Key) mode and full

WPA mode are supported. WPA is composed of TKIP (Temporal Key Integrity Protocol)

and IEEE 802.1x and serves as a successor to WEP for better WLAN security.

Repeater. When the AP is in AP/Bridge mode, it can communicate with other APs or

wireless bridges via WDS (Wireless Distribution System). Therefore, an AP can wirelessly

forward packets from wireless clients to another AP, and then the later AP forwards the

packets to the Ethernet network.

Antenna alignment assistance.The AP provides a WDS link quality indicator

via Wireless Network Manager to facilitate alignment of directional antennas when

deploying pairs of wireless bridges.

Link health monitoring. This feature enables the administrator to see if the WDS

links of the AP to other peer wireless bridges are working fine.

Wireless client isolation. When the AP is in AP/Bridge mode, wireless-to-wireless

traffic can be blocked so that the wireless clients cannot see each other. This capability can

be used in hotspots applications to prevent wireless hackers from attacking other wireless

users’ computers.

AP load balancing. Several APs can form a load-balancing group. Within a group,

wireless client associations and traffic load can be shared among the APs. This function is

available when the AP is in AP/Bridge mode.

Transmit power control. Transmit power of the AP’s RF module can be adjusted to

change RF coverage of the AP.

Link integrity. When the AP is in AP/Bridge mode and its Ethernet LAN interface is de-

tected to be disconnected from the wired network, all currently associated wireless clients

are disassociated by the AP and no wireless client can associate with it.

Association control. When the AP is in AP/Bridge mode, it can be configured to deny

association requests when it has served too many wireless clients or traffic load is too

heavy.

Associated wireless clients status. When the AP is in AP/Bridge mode, it can show

the status of all wireless clients that are associated with the AP.

Detachable antennas. The factory-mounted antennas can be replaced with high-gain

antennas for different purposes.

zDHCP client. The AP can automatically obtain an IP address from a DHCP server.

zDHCP server. The AP can automatically assign IP addresses to computers or other devices by

DHCP (Dynamic Host Configuration Protocol).

Static DHCP mappings. The administrator can specify static IP address to MAC ad-

dress mappings so that the specified IP addresses are always assigned to the hosts with the

specified MAC addresses.

Showing current DHCP mappings. Showing which IP address is assigned to which

host identified by an MAC address.

zPacket Filtering. The AP provides Layer 2, Layer 3, and Layer 4 filtering capabilities.

zFirmware Tools

Firmware upgrade. The firmware of the AP can be upgraded in the following methods:

TFTP-based. Upgrading firmware by TFTP (Trivial File Transfer Protocol).

HTTP-based. Upgrading firmware by HTTP (HeperText Transfer Protocol).

Configuration backup. The configuration settings of the AP can be backed up to a file

via TFTP or HTTP for later restoring.

Configuration reset. Resetting the configuration settings to factory-default values.

zManagement

Windows-based Wireless Network Manager for configuring, monitoring, and diag-

nosing the local computer and neighboring APs. The management protocol is MAC-based.

Web-based Network Manager for configuring and monitoring the AP via a Web

browser. The management protocol is HTTP (HeperText Transfer Protocol)-based.

SNMP. SNMP (Simple Network Management Protocol) MIB I, MIB II, IEEE 802.1d,

IEEE 802.1x, and Private Enterprise MIB are supported.

UPnP. The AP responds to UPnP discovery messages so that a Windows XP user can lo-

cate the AP in My Network Places and use a Web browser to configure it.

Telnet. The user is enabled to manage the AP by Telnet.

System log. For system operational status monitoring.

Local log. System events are logged to the on-board RAM of the AP and can be

viewed using a Web browser.

Remote log by SNMP trap. Systems events are sent in the form of SNMP traps to

a remote SNMP management server.

zPower over Ethernet. Supplying power to an AP over an Ethernet cable using PowerDsine

(http://www.powerdsine.com) technology (IEEE 802.3af compliant in the future). This feature

facilitates large-scale wireless LAN deployment.

zHardware Watchdog Timer. If the firmware gets stuck in an invalid state, the hardware

watchdog timer will detect this situation and restart the AP. This way, the AP can provide con-

tinuous services.
