Page 7: Chapter 1. Site Planning
Tsunami Multipoint Version 1.3 Installation Guide Chapter 1. Site Planning The installation of a wireless network requires much the same basic planning as any wired network. The main difference is that the wireless signal requires some additional planning. This planning includes RF path planning, site preparation, and installation of outdoor components, such as outdoor units, antennas, lightning protection devices, and cabling suitable for outdoor conditions. -
Page 8: Specific Considerations
Tsunami Multipoint Version 1.3 Installation Guide Specific Considerations Weather You should research any unusual weather conditions common to the site location. These conditions can include excessive amounts of rain, wind velocity, or extreme temperature ranges. If extreme conditions exist that may affect the integrity of the radio link, take these conditions into consideration early in the planning process. - Page 9 Tsunami Multipoint Version 1.3 Installation Guide 4.45 to obtain newtons, or by 0.45 to obtain kilograms of force. Similarly, foot-pounds can be multiplied by 1.36 to obtain Newton-meters, or by 0.138 to obtain kgm-meters. Note: For definitions of wind loading specifications for antennas and towers, refer to TIA/EIA-195 (for antennas) or TIA/EIA-222 (for towers) specifications.

Page 10: Interference And How To Avoid It
Note: The Tsunami Multipoint product line includes a BSU that provides spectrum shielding. This BSU model can reject interference at the uplink location. If interference from other systems is a problem, Proxim recommends you use a BSU equipped with this feature. -
Page 11: Antennas
▪ Reducing the power of interfering sources not directly aligned to the antenna Tsunami Multipoint Ethernet Systems use integrated directional antennas that transmit and receive a relatively narrow beamwidth of radio energy, improving system performance by reducing the likelihood that surrounding RF clutter will interfere with reception. The antennas with this system are directional and cannot be detached. - Page 12 Tsunami Multipoint Version 1.3 Installation Guide BSU Antenna Characteristics Polarization: LHCP (Left-Hand Circular Polarization) Azimuth Beamwidth: 60-degree Elevation Beamwidth: 6-degree Figure 3. BSU Azimuth Antenna Pattern Figure 4. BSU Elevation Antenna Pattern Chapter 1. Site Planning CPN 63179 Issue Date: 01/24/03...
- Page 13 Antennas are tuned to operate on a specific group of frequencies. Antenna Polarization The Tsunami Multipoint system uses left-hand circular polarization. As a result, the signal is successfully received regardless of the orientation of the antenna. Circular polarization also provides protection against multi-path degradation of the signal quality.

“type approved” by the FCC or local government for use within the specific band. PMP Radio Information The following sections provide information about the Tsunami Multipoint radio components. See “Appendix C. Technical Specifications” on page 57 for product technical specifications. Chapter 1. Site Planning... - Page 15 Tsunami Multipoint Version 1.3 Installation Guide Channel/Frequency Plans Tsunami Multipoint offers several frequency plans to provide a means for overcoming interference. If one part of the 5.8 GHz spectrum is occupied when you deploy the product, you can select a different frequency plan to bypass the interfering frequency.

Proxim recommends that you retain all the packaging materials (including all internal boxes). In the unlikely event that the equipment must be returned to the factory, use the original packing materials for return shipment. -
Page 17: Mounting The Base Station Unit
Mounting the Base Station Unit You can mount the outdoor component of your Tsunami Multipoint Base Station Unit directly to a pole with an outside diameter of 1- ½ to 4- ½ inches. Mounting the BSU is essentially a two-step process: 1. - Page 18 Tsunami Multipoint Version 1.3 Installation Guide Figure 7.
