Why Buy Cisco Antennas?

There are major advantages to buying antennas from Cisco. This paper describes
Cisco’s antenna technology from design to testing and how that guarantees
customers get a great product.

Introduction

There are many antenna suppliers capable of delivering Wi-Fi antenna solutions. However, it can be difficult, if not

impossible, to know which one will deliver a high-quality solution with products that meet their advertised

specifications and one that will really work for your particular installation. It may be very difficult to verify

performance. The tools needed for that are highly specialized, large, and expensive.

The solution to these challenges is simple: Cisco should be the antenna supplier for your Wi-Fi network. There are

a variety of reasons for that choice.

●

Cisco

antennas go through complete electrical, mechanical, and environmental testing to ensure the

specifications accurately reflect the product and that they meet requirements.

●

Cisco has the experienced staff and tools to design, build, and test many of the antennas in the product

line. We understand antennas.

●

Cisco has long-standing relationships with other antenna suppliers who understand that Cisco customers

require high-quality, high-performing antennas.

●

All Cisco wireless network features like the Cisco Wireless Control System, radio resource management

(RRM), rogue access point detection, and location services are all tested with Cisco antennas. These

features demand the consistent, repeatable performance that Cisco antennas deliver.

●

You get the full support of the Cisco Technical Assistance Center (TAC) when you use Cisco antennas.

This paper contains an in-depth look at Cisco’s antenna-related capabilities. However, we begin by highlighting a

couple basic antenna terms that will be crucial to demonstrations later in the paper. Gain and beamwidth are

explained since they are the two most commonly discussed antenna parameters when it comes to Wi-Fi antennas.

For a complete description of antenna parameters and what they mean, see the Cisco white paper entitled,

“Antenna Patterns and Their Meaning”. You can download it from:

Since antenna measurements are crucial to understanding how an antenna might perform in your system, a full

description of Cisco’s antenna measurement system is included in this paper along with how its use fits into our

overall plan for design verification or the qualification of third-party antennas. Next, a description of Cisco’s

antenna design capabilities demonstrates our serious commitment to providing high-quality antenna solutions.

Finally, we discuss our complete line of antennas, a sampling of which are shown in Figure 1. We make some

basic recommendations about the use of several Cisco antennas and provide a full description of the benefits of

choosing Cisco as your antenna supplier.
