Choosing Antennas for Wireless Network Configurations
Choosing Antennas for Wireless Network Configurations
The type and number of antennas that you need depend on the configuration of your wireless network. Table 1‐1 lists the general type of antenna to use for various wireless network configurations.
Table 1-1
Antennas for Wireless Network Configurations
Wireless Network
Configuration
Description
Antenna Type
LAN-to-LAN Point-to-Point
(RBT-4102 only)
This is a wireless link between
two APs that connects two
separate wired LANs.
Directional antennas, typically two.
LAN-to-LAN Point-to-Multipoint
(RBT-4102 only)
In a point-to-multipoint network,
up to nine APs provide wireless
links to connect up to nine LANs.
One AP is designated as the
central (multipoint) AP. The other
APs are called endpoints and only
communicate with the Central AP.
Omni-Directional antenna - to
which the Central AP connects.
This is an inside/outside wireless
network where one or more APs
are used to connect clients to a
wired LAN.
An Omni-Directional or a sectored
antenna.
Wireless Infrastructure

Site Preparation
Directional antennas - to which the
Endpoint APs connect.
Determining the Antenna Locations
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 RoamAbout antennas are described in Antenna Models on page 1‐9. •
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.
Typically, the RoamAbout directional and omni‐directional antennas are installed on rooftops. The directional antenna can also be installed on the side of a building. The following sections describe the factors that affect the range of the antennas.
Distances with Cables
Table 1‐2 lists the distances for the RBT‐4102, RBT‐4102‐EU, and the RBT‐4102 ‐BG. The distances include the cables at both ends. For every 6 dBi of cable loss, divide the distance by two. For every 10 dBi of cable loss, divide the distance by three.
.
Notes:
• Be sure to calculate the cable loss at both ends, and include the pigtails.
• The distance miles listed are approximate.
• If the RBT-4102-EU uses one 8 dBi (RBTES-BG-M08M) to one or more 14 dBi sector
antenna(s), you will get approximately half the distances shown in Table 1-2 using the 2.4 GHz
band.

Determining the Antenna Locations
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 Figure 1‐1. 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. Figure 1-1
Fresnel Zone and Line of Sight Clearance
Total Distance
Radius
If a significant part of the Fresnel Zone is obstructed, a portion of radio energy is lost, resulting in reduced performance. For optimal performance, ensure that the antenna products you choose, in combination with the height of the antenna installation above ground, provide sufficient 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 Figure 1‐2.

Potential Obstacles to Line of Sight (not to scale)
Determining the Antenna Locations
Other Factors That Can Reduce Antenna Range
Large reflecting surfaces that are parallel or partly perpendicular to the radio signal cause reflections of the radio signal (see Figure 1‐3). Examples of reflecting surfaces are buildings with low‐emissivity (low‐e) glass, crowded parking lots, water, moist earth, moist vegetation, and above‐ground power or telephone lines.
Because surrounding objects, such as trees, power lines, and other antennas, seriously reduce efficiency of the antenna, it is very important to mount the antenna as high and clear of obstacles as possible.

Determining the Antenna Locations
Additional Location Requirements
This section describes other requirements to meet before installing the RoamAbout outdoor antennas. •
Lightning Protection
A lightning rod must be placed close to the antenna mast or wall bracket. This is required to protect the antenna from direct lightning strikes.
•
Grounding System
Direct earth grounding of the antenna and the Lightning Protector is necessary to protect the installation from lightning and the build‐up of static electricity. The wireless device and the Lightning Protector must be connected to the same earth ground using separate grounds. The antenna and the mounting structure require separate grounds to the same earth ground, using an equipotential bonding conductor. Check with a certified antenna installer, or local electrician, to make sure the antenna is properly grounded.
Ensure that the cable between the antenna and Lightning Protector is at least 0.9 meters (3 feet) away from high‐voltage or high‐current cable.
•
Antenna Height
If you are mounting the antenna on a roof, it must be at least 1.5 meters (5 feet) above the roof line.
If you are mounting the directional antenna to a wall of a building, it must be high enough to achieve a clear line of sight. Mounting an omni‐directional antenna to the side of a building can cause signal reflection and reduce distance.
Note: The installer is responsible for local building codes.
•
AP placement
The AP should be located indoors, and connected to the outdoor antenna using the shortest cable possible to reduce the loss of the cable.

AP Placement and Configuration
This chapter provides information for the antenna installer and network manager to determine where to place the RoamAbout AP and Lightning Protector. Determining the Location of the AP
The RoamAbout AP connects to a Lightning Protector with a 51‐centimeter (20‐inch) cable. The Lightning Protector connects to the outdoor antenna with a standard 6.1‐meter (20‐foot), 7.6‐meter (25‐foot), 15.24‐meters (50‐foot), or a 22‐meter (75‐foot) low‐loss cable. A longer cable will decrease the distance achievable between antennas. The ideal location to install your RoamAbout AP and Lightning Protector must satisfy the following requirements:
•
The location must be indoors to protect the AP from extreme weather conditions, excessive heat and humidity, and to keep the unit free from vibration and dust.
•
The Lightning Protector and antenna mast must be connected to the same earth ground (using separate grounds), as the AC wall outlet ground using an equipotential bonding conductor.
•
The location must provide a connection to the network backbone via an Ethernet LAN cable going to a hub, bridge, or directly into a patch panel.
•
The location must be close to where the low‐loss antenna cable will enter the building. The low‐loss cable connecting the antenna to the Lightning Protector should not exceed 75 feet in length for 2.4 GHz, or 50 feet in length for 5 GHz, due to the distance reduction with longer cables.

Mounting the Antenna
Mounting the Antenna
This section includes requirements and mounting guidelines for the RoamAbout outdoor antennas. Each antenna mounting section contains an illustration of the antenna, component description, and a mounting procedure.
Selecting a Mast
Note: You must supply your own mast on which to mount a RoamAbout antenna. RoamAbout
antennas do not come with masts.
To minimize the influence of obstacles, signal interference or reflections, install the antenna at least 2 meters (6 feet) away from all other antennas.
If you need to mount multiple antennas on a single mast, alternate the mounting of directional antennas for vertical and horizontal polarization.
In subfreezing conditions, the communications link could fail if an antenna is exposed to ice buildup or covered with snow. The mast must satisfy the following requirements:
•
The mast must be constructed of sturdy, weatherproof, noncorrosive material such as galvanized or stainless steel construction pipe.
•
Mast diameters for each antenna should be as listed in Table 3‐2.
•
Antenna mast length must be sufficient to allow an antenna height at least 1.5 meters (5 feet) above the roof peak. If the roof is metal, the antenna height should be a minimum of 3 meters (10 feet) above the roof.

Mounting the Antenna
To mount the omni‐directional base station antenna to a mast, perform the following steps:
1.
With the mount situated so that the arrows stamped on its toothed surface face up, insert the top of the antenna through the center hole in the mount.
2.
Slide the mount down the antenna until it is seated securely around the base of the antenna.
Note: The mount’s center hole is tapered to match the taper of the antenna base. The antenna will
thus fit snugly into the mount’s center hole.
3.
Tighten the set screws on the sides of the mount until tight.
4.
Place the U‐bolt around the mast.

Connecting the Antenna Cables
Antenna Cable Route
The cable should not be installed into tight positions, as bending or applying excessive force to the connectors may damage the antenna cable. Always allow the cable to bend naturally around corners. The low‐loss antenna cable must be secured along its complete length. No part of the cable should be allowed to hang free. This is particularly important for cable parts that are installed outdoors. The antenna cables and cable connectors are not designed to withstand excessive force:
•
Do not use connectors as cable grips to pull cable through raceways or conduits.
•
Do not use cable connectors to support the weight of the cable during or after installation.
•
Do not use tools to tighten connectors (finger‐tighten only).
Connecting the Cables
Once the antenna is properly installed, you can connect the antenna to the RoamAbout AP via the RoamAbout Lightning Protector.
1.
Verify that the low‐loss antenna cable is properly connected to the antenna cable.
2.
Secure the low‐loss cable to the mast such that the cable connectors do not support the full weight of the cable.
3.
Provide a drip‐loop at the bottom of the low‐loss cable just before it enters the building.
4.
Connect the opposite end of the low‐loss cable to the RoamAbout Lightning Protector.
Caution: To avoid damage to the antenna cable and connectors, do not use tools to tighten cable
connectors.
Precaución: para evitar daños en los cables y el conector de la antena, no use herramientas para
apretar los conectores.
Achtung: Verwenden Sie kein Werkzeug zum Anziehen der Kabelanschlüsse. Durch Werkzeug
können das Kabel und die Anschlüsse beschädigt werden.
5.
Prior to securing the cable along its complete length, refer to “Optimizing RoamAbout Outdoor Point‐to‐Point Antenna Placement” on page 3‐37. If required, adjust the direction of the antenna.
6.
Once the installation has been fully tested, tighten antenna mounting nuts to lock the antenna into its position.
Caution: To prevent damage, avoid over-tightening the connectors, nuts, and screws used to
mount the antenna.
Precaución: evite apretar demasiado los conectores, tuercas y tornillos usados para instalar la
antena, para no dañarlos.
Achtung: Beugen Sie Schaden vor, indem Sie die Anschlüsse, Muttern und Schrauben für die
Antenne nicht zu fest anziehen.
3-36
7.
Secure the cable along its complete length. No part of the cable should be allowed to hang free.
8.
Use waterproof stretch tape to seal all outdoor connectors. Antenna Installation
Optimizing RoamAbout Outdoor Point-to-Point Antenna Placement
Optimizing RoamAbout Outdoor Point-to-Point Antenna
Placement
If an AP is connected to an outdoor directional antenna, the antenna must be pointed directly at the antenna for the other AP. A misaligned antenna can decrease the signal level or prevent communications. Aligning an omni‐directional antenna is less critical due to its wide radiation pattern. For optimal performance, make sure the antennas are properly aligned by using a pair of binoculars to point the antennas at each other.
Routine Maintenance
Routine maintenance is required for each RoamAbout Lightning Protector in your outdoor antenna installation. Maintenance involves replacing the Lightning Protector at some interval depending on the lightning/transient discharge activity in your area.
Note: Contact a local antenna installation company to determine the maintenance schedule for
each RoamAbout Lightning Protector in your outdoor antenna installation.
