It also includes brief descriptions of the RoamAbout indoor and outdoor antenna options. This information is intended for sales engineers or site evaluators. The antennas listed in this document are only for use with the RoamAbout Wireless Access Point RBT‐4102 and the Wireless Access Point RBT‐1602. Not all antennas listed in this document can be used by both wireless access points.
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.
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.
Determining the Antenna Locations Table 1-2 Outdoor Distance Matrix Between Antennas (RBT-4102 LAN to LAN/MultiPoint) GHz Antenna Cables used 5.7 - 5.8 RBTES-AH-P23M/M0M Pigtail and the LMR-600-C25F at each end (23 dBI to 10 dBI) For use in North America only. Pigtail and the LMR-600-C50F at each end Pigtail and the LMR-400-C50 at each end 5.4 - 5.7 RBTES-AW-S1590M (15 dBi to 15 dBI) Based on ETSI Standards.
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.
Determining the Antenna Locations Figure 1-2 1-6 Site Preparation 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.

Connecting the Antenna Cables Connecting the Antenna Cables The cable configuration that you use to connect your RoamAbout AP to an outdoor antenna varies based on whether you use: • A male or a female pigtail connector on your AP • A Lightning Protector The following sections show the various cable configurations. Using the Female Pigtail Figure 3‐19 and Figure 3‐20 show the cable configurations for using a female pigtail connector to connect an AP to an outdoor antenna.
Connecting the Antenna Cables Using The Male Pigtail Figure 3‐21 and Figure 3‐22 show the cable configurations for using a male pigtail connector to connect an AP to an outdoor antenna. Figure 3‐21 shows the configuration for using a Lightning Protector. Figure 3‐22 shows the configuration when not using a Lightning Protector. Table 3‐17 describes the configurations.
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.
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.
