CHAPTER 1: INTRODUCTION
USB ADAPTOR INTRODUCTION
Thank you for your purchase of the AIR802 USB ‐ ADG ‐ 2 adaptor. This USB adaptor offers great
value whether you are an individual purchasing for use at home or for use in a business of any
size.
USB adaptors are a simple and easy way to add wireless to a computer. The majority of
computers now ship with wireless cards built ‐ in, but users commonly find weak signals. This
weak signal can occur due to several factors. One it may be too far from a wireless router or
access point, most internal wireless cards do not provide significant radio frequency (RF) gain.
Another factor is that almost all built ‐ in cards have the antennas operating horizontally, where
the wireless router or access point has vertically polarized antennas. This results in significant
signal loss. Whatever the resulting cause of the weak signal is, the USB ‐ ADG ‐ 2 with its external
and removable antenna will enhance your wireless experience. This key to successful wireless
exerience is the external and removable antenna with the flexibility of using alternative
antennas.
The compact design makes it easy for you to travel with the adaptor. It draws its power from
the USB port, so you do not need an external power supply.
This adaptor supports high speed networking up to 54 Mbps per the IEEE 802.11g specification.
Of course, most broadband connections are DSL or cable modems that are limited generally to
less than 6 Mbps, which determines the ultimate throughput rates in accessing the Internet.
As with all USB stick type devices care should be taken while connected to a laptop.
