Contacting an Antenna Installation Company

This chapter describes the site requirements for the successful installation of ExtremeWireless antennas.

This information is intended for sales engineers or site evaluators.

Warning

Site prerequisites should be veriﬁed by a person familiar with national codes, local electrical

codes, and with other regulations governing this type of installation. Extreme Networks, its

channel partners, resellers, and distributors assume no liability for personal injury, property

damage, or violation of government regulations that may arise from failing to comply with the

instructions in this guide.

ExtremeWireless Access Points that Support External Antennas

Not all antennas listed in this document can be used by all wireless access points. If the name of the

access point ends with an "e", the access point supports external antennas. For example, the AP3935e

supports external antennas. For legacy access points, refer to ExtremeWireless™ External Antenna Site

Preparation and Installation Guide (P/N 9034559-09) to determine if your legacy access point supports

external antennas. Antenna Models identiﬁes which antennas are supported by each AP.

Choosing Antennas for Wireless Network Conﬁgurations

The type and number of antennas that you need depend on the conﬁguration of your wireless network.

The following table lists the general type of antenna to use for various wireless network conﬁgurations.

ExtremeWireless™ External Antenna with Wave 2 7

Table 3: Antennas for Wireless Network Conﬁgurations

Network Conﬁguration Description Antenna Type

LAN-to-LAN Point-to-Point This is a wireless link between two WDS

APs that connects two separate wired

LANs. (WDS APs are conﬁgured to

operate as Workgroup bridges.)

Directional antennas

LAN-to-LAN Point-to-Multipoint In a point-to-multipoint network, up to

nine WDS APs provide wireless links to

connect up to nine LANs. One AP is

designated as the root (multipoint) AP

connected to a wired infrastructure. The

other APs are called child APs. Child APs

establish a backhaul connection with the

root AP and, at the same time, provide

LAN switching.

Omni-Directional antenna— to

which the root AP connects.

Directional antennas— to which

the child APs connect.

Wireless Infrastructure This is an inside/outside wireless

network where one or more WDS APs

are used to establish a wireless backhaul

and connect clients or LAN segments to

the wired LAN.

An Omni-Directional or a sectored

antenna.

Determining the Antenna Locations

The following factors determine the locations where you can place the antennas relative to one another

and the distances between them:

•Type of antennas. The ExtremeWireless antennas are described in Antenna Installation on page 23.

•Length of cable connecting the antenna to the AP.

•Data rate required.

•In a LAN-to-LAN network, the distance between the buildings.

•Obstructions in the signal path.

•In a wireless infrastructure network, the area around the antenna where clients need to

communicate with the AP.

Directional and omni-directional antennas are often installed on rooftops. The directional antenna can

also be installed on the side of a building. The following sections describe the factors that aect the

range of these antennas.

Line of Sight

The shape of the radio beam, deﬁned as the Fresnel Zone, is widest in the middle. The Fresnel Zone is

shown as the gray area between the antennas in Fresnel Zone and Line of Sight Clearance. The exact

shape and width of the Fresnel Zone is determined by the distance between the antenna and frequency

of the radio signal.

The radius of the radio beam, shown as the lower half of the Fresnel Zone, is the distance from the

center of the beam outward in any direction. The length of the radius is not based on the data rate and

the type of antenna.

AP Site Preparation

ExtremeWireless™ External Antenna with Wave 2 8

Figure 1: Fresnel Zone and Line of Sight Clearance

The radius can be calculated using the following formula:

Where

D = Distance between the antennas in kilometers

f = Frequency in GHz

60% of the Fresnel Zone has to be clear of obstructions to be line of sight. In addition to the Fresnel

Zone height requirement, earth curvature may become a factor in paths longer than 2 Km. The

additional antenna height can be calculated using the following formula:

Where

D = Distance between the antennas in kilometers

H = Height required to overcome earth curvature

and Table 5 on page 10 lists typical antenna height requirements.

For optimal performance, ensure that the antenna products you choose, in combination with the height

of the antenna installation above ground, provide sucient clearance to allow your antenna installation

to cover the distance between the two sites.

Obstacles within the line of sight can signiﬁcantly reduce the distance and performance. Obstructions

include neighboring buildings, trees, and power lines, as shown in the following ﬁgure:
