  • Page 7: Introduction

    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.
  • Page 8 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.

    2.3. Preparing for Configuration For you to configure an IWE1700-A, a managing computer with a Web browser is needed. For first-time configuration of an IWE1700-A, an Ethernet network interface card (NIC) should have been installed in the managing computer. For maintenance-configuration of a deployed IWE1700-A, either a wireless computer or a wired computer can be employed as the managing computer.
