OVERVIEW

1.1 Description

The Emerald USB Antenna is a 2.4 GHz flat panel 18dBi gain directional antenna with a

built-in USB adapter using an 11Mbps 802.11b WiFi

compliant WLAN Card. It

provides long-range high-speed wireless connectivity for the USB-enabled desktop PC

or laptop computers.

A 25-foot USB cable is included, but can be extended using active repeating extension

cables. The antenna is intended for outdoor or long range use, and can be pole or wall-

mounted for fixed wireless connectivity.

The Emerald USB Antenna offers the simplest, most efficient 2.4 GHz Wireless Internet

Access solution for a desktop PC. The Emerald USB Antenna will communicate with

any other wireless device that is WiFi compatible. When used with ORiNOCO Access

Points, it has full-featured Link Test capabilities. This shows the connection’s data rate

and radio link margins in both directions.

There’s no need to open a customer’s PC to install an interface card, and no worries

about IRQ device conflicts, finding vacant ISA or PCI slots, or dealing with external

power supplies and cables. Just attach the included 25-foot USB cable (plus optional

extension cables) to the Emerald USB Antenna, plug into an available USB jack on your

computer, and your hardware installation is complete!

With the USB adapter built right in to the antenna, there’s no complicated hardware

configuration or RF cables to deal with. And because the Emerald USB Antenna has the

radio built in, professional antenna installation is not required. All you have to do is

make sure the flat panel antenna is optimally aimed and has clear line of sight to the

base station. With the Windows-based Client Manager software provided, the signal

strength and signal-to-noise ratio (SNR) displays make aiming the antenna a snap.
