Introduction
Overview
The Gigabyte WLMA102 Dual-Band Notebook Adapter Card delivers to you with today’s
fastest available wireless connection, and prepares you for the future. Without having to
swap notebook adapters, the WLMA102 lets you connect seamlessly to both 2.4GHz,
802.11b/g and 5.0GHz 802.11a wireless networks.
With Gigabyte’s exclusive SmartSetup 3, setup is a breeze. Connect and secure with
WPA in no time. The 802.11a wireless network operates in the less crowded 5GHz radio
band, so its becoming more popular as 802.11b/g networks get crowded with traffic.
The 32-bit PC Card WLMA102 Super G Wireless Adapter communicates over the 2.4GHz
802.11g wireless standard with throughput up to 15 times faster than the 11Mbps 802.11b
while still remaining fully backward compatible with that standard.
Notebook PC’s equipped with wireless adapters communicate with Wi-Fi Application
Points and wireless routers giving you the freedom of mobility, and the convenience of
getting online virtually wherever, and whenever there is a wireless network – keep in
touch with friends and family via email, instant messaging or just surfing the net, from
home, the airport, coffee shop or convention halls .
This manual will help you understand more about the powerful features and options of
your newWLMA102 Dual-Band A+GWireless Notebook Adapter.

Operating Modes
The GN-WLMA102 Notebook Card can operate in all of today’s wireless radio
bands:
4

Super G Wireless NotebookAdapter
•802.11b (11b) – The 802.11b wireless radio has a range of about 50
meters and a maximum throughput of 11 Mbit/s, however a significant
percentage of this bandwidth is used for communications overhead; in
practice the maximum throughput is about 5.5 Mbit/s. Although it’s
slower than 11g, it’s still the most commonly used network today.
•802.11g (11g) - In June 2003, a third standard for Wi-Fi was ratified:
802.11g. This version works in the 2.4 GHz band (like 802.11b) but
operates at 54 Mbit/s raw, or about 24.7 Mbit/s net, throughput like
802.11a. It is fully backwards compatible with 11b and uses the same
frequencies.
•802.11a (11a) - The 802.11a standard uses the 5 GHz band, and
operates at a raw speed of 54 Mbit/s, with net achievable speeds in
the mid-20 Mbit/s. The speed is reduced to 48, 36, 34, 18, 12, 9 then 6
Mbit/s as required to connect to slower AP’s. 802.11a has 12
non-overlapping channels, 8 dedicated to indoor and 4 to point to
point.
These and other advanced configuration options are explained further in
Chapter 3 - Configuring the WLMA102.
