About the Wireless Access Point

Congratulations on your purchase of NETGEAR's WAB102 802.11 a+b Dual

Band Wireless Access Point, which gives you the ultimate in office mobility. This

high-speed wireless device simultaneously supports both IEEE 802.11a and

802.11b wireless networks and lets you quickly network multiple PCs and

notebooks without laying new cables, and gives users the freedom to roam

throughout the workplace and stay connected to corporate resources, e-mail, and

the Internet.

The WAB102 provides built-in capacity and flexibility for growing networks so

it's easy to add new clients or move your entire network to a new location.

Equipped with auto-sensing capability, it allows packet transfer at up to 108 Mbps

in turbo mode for maximum throughput. This access point will automatically

adjust to the most efficient speed for the maximum distance in a noisy

environment.

2Introduction

Benefits

• Ultimate mobility – One Access point provides both 802.11a (5 GHz) and

802.11b (2.4 GHz) wireless networks.

• Blazing fast speeds – Up to 54 Mbps, and up to 108 Mbps in turbo mode for

models shipped in the United States, Canada, and Australia.

• Dual band capability protects your existing 802.11b wireless network

investment while installing a new 802.11a network.

• Seamlessly integrates into an existing 10 Mbps or 100 Mbps Fast Ethernet

LAN.

Features

The key features of the WAB102 802.11 a+b Dual Band Wireless Access Point

are:

• Reliable IEEE 802.11a and 802.11b standards-based wireless technology.

• Interfaces directly to 10 Mbps IEEE 802.3 Ethernet and 100 Mbps IEEE

802.3u Fast Ethernet networks.

• Up to 108 Mbps high-speed rate in turbo mode (for models shipped in the

United States, Canada, and Australia). Wireless nodes negotiate to operate at

an optimal data transfer rate. In a noisy environment or when the distance

between the wireless nodes is too far, the wireless nodes will automatically

adjust to the most efficient speed for the distance.

• Provides the highest available level of industry-standard WEP encryption:

128-bit for 802.11b devices and up to 152-bit for 802.11a devices

• MAC Address Filtering provides increased security.

• Extensive coverage and available bandwidth with twelve (12)

non-overlapping channels in the 5 GHz band (5.15 to 5.35 GHz, 5.725 to

5.825 GHz); three (3) non-overlapping channels in the 2.4 GHz band (2.412

to 2.484 GHz)

• Supports Dynamic Frequency Selection (DFS) to avoid cross interference

with radar systems used in certain European countries.

• Supports Transmit Power Control (TPC) for use in Europe.
