Cisco Aironet Antennas and Accessories

Overview

Executive Overview

This antenna reference guide is intended to provide information to assist in understanding the

issues and concerns of antennas used with a Cisco

Aironet

wireless LAN system, or wireless

bridge system. It details deployment and design, limitations and capabilities, and basic theories

of antennas. This document also contains information about the Cisco Systems

antennas and

accessories, as well as installation scenarios, regulatory information, and technical specifications

and diagrams of the available antennas.

Overview of Antennas

Each Cisco Aironet radio product is designed to perform in a variety of environments.

Implementing the antenna system can greatly improve coverage and performance. To optimize the

overall performance of a Cisco wireless LAN, it is important to understand how to maximize radio

coverage with the appropriate antenna selection and placement. An antenna system comprises

numerous components, including the antenna, mounting hardware, connectors, antenna cabling,

and in some cases, a lightning arrestor. For a consultation, please contact a Cisco Aironet

partner at

http://tools.cisco.com/WWChannels/LOCATR/jsp/partner_locator.jsp.

Cisco partners can provide onsite engineering assistance for complex requirements.

Radio Technologies

In the mid-1980s, the U.S. Federal Communications Commission (FCC) modified Part 15 of the

radio spectrum regulation, which governs unlicensed devices. The modification authorized wireless

network products to operate in the Industrial, Scientific, and Medical (ISM) bands using spread

spectrum modulation. This type of modulation had formerly been classified and permitted only in

military products. The ISM frequencies are in three different bands, located at 900 MHz, 2.4 GHz,

and 5 GHz. This document covers both the 2.4- and 5-GHz bands.

The ISM bands typically allow users to operate wireless products without requiring specific

licenses, but this will vary in some countries. In the United States, there is no requirement for FCC

licenses. The products themselves must meet certain requirements to be certified for sale, such as

operation under 1-watt transmitter output power (in the United States) and maximum antenna gain

or Effective Isotropic Radiated Power (EIRP) ratings.

The Cisco Aironet product lines utilize both the 2.4- and 5-GHz bands. In the United States, three

bands are defined as unlicensed and known as the ISM bands. The ISM bands are as follows:

●

900 MHz (902-928 MHz)

●

2.4 GHz (2.4-2.4835 GHz)—IEEE 802.11b

●

5 GHz (5.15-5.35 and 5.725-5.825 GHz)—IEEE 802.11a, HIPERLAN/1 and HIPERLAN/2.

This band is also known as the UNII band, and has 3 sub-bands, UNII1 (5.150-5.250 GHz),

UNII2 (5.250-5.350 GHz) and UNII3 (5.725-5.825 GHz)

Reference Guide Each range has different characteristics. The lower frequencies exhibit better range, but with limited bandwidth and hence lower data rates. The higher frequencies have less range and are subject to greater attenuation from solid objects. Direct Sequence Spread Spectrum The Direct Sequence (DS) Spread Spectrum approach involves encoding redundant information into the RF signal. Every data bit is expanded to a string of chips called a chipping sequence or Barker sequence.
PAGE 3
Reference Guide Unlike isotropic antennas, dipole antennas are real antennas (dipole antennas are standard on Cisco Aironet access points, base stations, and workgroup bridges). Dipole antennas have a different radiation pattern compared to isotropic antennas. The dipole radiation pattern is 360 degrees in the horizontal plane and 75 degrees in the vertical plane (assuming the dipole antenna is standing vertically) and resembles a donut in shape.

Reference Guide Figure 2. Directional Patch Antenna Figure 3. YAGI Antenna Diversity Antenna Systems Diversity antenna systems are used to overcome a phenomenon known as multipath distortion of multipath fading. It uses two identical antennas, located a small distance apart, to provide coverage to the same physical area. Multipath Distortion Multipath interference occurs when an RF signal has more than one path between a receiver and a transmitter.
PAGE 5
Reference Guide Figure 4. Multipath Distortion You can relate this to a common occurrence in your car. As you pull up to a stop, you may notice static on the radio. But as you move forward a few inches or feet, the station starts to come in more clearly. By rolling forward, you move the antenna slightly, out of the point where the multiple signals converge. A diversity antenna system can be compared to a switch that selects one antenna or another, never both at the same time.
PAGE 6
Reference Guide The Physical Environment After mobility issues are resolved, the physical environment must be examined. While the area of coverage is the most important determining factor for antenna selection, it is not the sole decision criteria. Building construction, ceiling height, internal obstructions, available mounting locations, and customer aesthetic desires also must be considered. Cement and steel construction have different radio propagation characteristics.
PAGE 7
Reference Guide ● Small Office/Small Retail: The standard dipole may provide adequate coverage in these areas depending on the location of the radio device. However, in a back corner office a patch antenna may provide better coverage. It can be mounted to the wall above most obstructions for best performance. Coverage of this type antenna depends on the surrounding environment. ● Enterprise/Large Retail: In most cases, these installations require a large coverage area.

Reference Guide mounting the antenna away from the radio unit. The 100 and 150 foot cables are LMR600 type cable, while the 20 and 50 foot cables are LMR400 type cables. All four lengths are supplied with one RP-TNC plug and one RP-TNC jack connector attached. This allows for connection to the radio unit and to the interconnect cable supplied on the antennas. Connectors According to the US Federal Code of Regulations, products used in the 2.

Reference Guide Figure 5. Cisco Aironet Lightning Arrestor The accepted IEEE transient (surge) suppression is .000008 seconds (8 micro seconds). The Lightning Arrestor is a 50-ohm transmission line with a gas discharge tube positioned between the center conductor and ground. This gas discharge tube changes from an open circuit to a short circuit almost instantaneously in the presence of voltage and energy surges, providing a path to ground for the energy surge.

Reference Guide Figure 6. Fresnel Zone Based on both line-of-sight and Fresnel zone requirements, Table 3 provides a guideline on height requirements for 2.4 GHz antennas as various distances. This refers to height above any obstacles located in the middle of the RF path. Table 3. Guideline on Height Requirements for 2.4 GHz Antennas Wireless Link Distance (miles) Approx.

Reference Guide rules are intended to discourage use of amplifiers, high-gain antennas, or other means of significantly increasing RF radiation. The rules are further intended to discourage “home brew” systems which are installed by inexperienced users and which—either accidentally or intentionally—do not comply with FCC regulations for use in the ISM band.
PAGE 13
Reference Guide The main issue that comes to question here is, what differentiates a point-to-point from a multipoint system. In Figure 7, point A communicates to a single point, B, and point B communicates to a single point A; therefore, it is simple to see that both locations see this as a point-to-point installation. In Figure 8, point A communicates to more than one (or multiple) points; therefore, point A is operating in a multipoint configuration, and the largest antenna permitted is 16 dBi.
PAGE 14
Reference Guide overall gain of the transmitter, plus the antenna gain, less any losses in coax, is equal to or less than +20 dBm. This drastically reduces the overall distance an outdoor link can operate. ● Amplifiers: Since the ETSI regulation has such a low EIRP, the use of amplifiers is typically not permitted in any ETSI system. Frequencies and Channel Sets IEEE 802.11b/g Direct Sequence Channels Fourteen channels are defined in the IEEE 802.11b/g Direct Sequence (DS) channel set.
