Preparing for Installation Installation Process Overview Tsunami MP.11 Antenna Installation Guide Installation Process Overview The installation process can be summarized in the following steps: 1. Verify that the support structure for the antenna and radio has been connected to the grounding system. If this is not the case, connect it properly. 2. Mount the antenna to the support structure, following the guidelines as described for your antenna’s documentation.
Preparing for Installation Indoor-Mounted Radio Hardware and Cable Overview Tsunami MP.11 Antenna Installation Guide Indoor-Mounted Radio Hardware and Cable Overview Indoor Radio Hardware Model 5054, 5012-SUI, and 5054-SUI radios are intended for indoor mounting and operation. For these indoor radios, the antenna cable is connected to the connector pigtail extending from the radio.

Outdoor units are referred to collectively as MP.11-R units. To make optimal use of the units, you must find a suitable location for the hardware.
Preparing for Installation Outdoor-Mounted Radio Hardware and Cable Overview Tsunami MP.11 Antenna Installation Guide Power Injector for Outdoor Units The power injector is designed for indoor mounting and operation. In addition to supplying power to the radio unit there is a data output connection on the power supply.
Preparing for Installation Additional Information for All Models Tsunami MP.11 Antenna Installation Guide Additional Information for All Models Surge Arrestor The surge arrestor is an indispensable part of your outdoor radio installation. It protects your sensitive electronic equipment from transients or electrostatic discharges at the antenna. For optimal protection, the surge arrestor must be installed at a location that is very near to where the CAT5 Ethernet cable enters inside the structure.

Installing the Link Required Materials Tsunami MP.11 Antenna Installation Guide IMPORTANT! Before climbing the roof to begin installation, check whether you have all the required components to set up an outdoor wireless link.
Installing the Link Determining Optimal Antenna Placement Tsunami MP.11 Antenna Installation Guide Determining Optimal Antenna Placement To achieve maximum performance of your wireless outdoor link, the outdoor antenna must have clear line-of-sight to the antenna of the other unit. Although the radio signal can work well without line-of-sight in urban environments in which the signal is transported by reflection rather than being direct, the best results are achieved in line-of-sight conditions.
Installing the Link Determining Optimal Antenna Placement Tsunami MP.11 Antenna Installation Guide To minimize the influence of obstacles, signal interference, or reflections, note the following guidelines: • Mount the antenna as high as possible above the ground to allow maximum clearance: – In open areas, ground is the actual surface of the earth. – In dense urban areas, ground is to be interpreted as the height of the highest obstacle in the signal path between the two antenna sites.
Installing the Link Determining Optimal Antenna Placement Tsunami MP.11 Antenna Installation Guide Long distance links may be obstructed by earth curvature, so the antenna height requirements must not only take the height of obstructions and Fresnel Zone into account, but also earth bulge. The earth bulge is approximately 5 m (16.4 ft.) at a link distance of 16 Km (10 mi.). In these cases, consult your supplier to take appropriate steps to maintain or optimize wireless link performance.
Installing the Link Mounting the Antenna Tsunami MP.11 Antenna Installation Guide Mounting the Antenna NOTE: As the mounting procedures for the various antennas differ from one another, consult the documentation you received from the manufacturer for mounting procedures. Proxim offers multiple antennas to set up a wireless link. See the Tsunami MP.11 Recommended Antennas guide.
Installing the Link Connecting the Antenna Cable Tsunami MP.11 Antenna Installation Guide Connecting the Antenna Cable Once the antenna is properly mounted, you can connect the antenna to the radio. 1. Connect the antenna cable to the antenna. 2. Secure the antenna cable to the mast so that the cable connectors do not support the full weight of the cable. 3. Connect the opposite end of the antenna cable to the radio.
Installing the Link Sealing the Cable Connectors Tsunami MP.11 Antenna Installation Guide Sealing the Cable Connectors Most problems associated with wireless outdoor installations are related to degrading performance due to corrosion of the antenna cable and cable connectors. To avoid this type of problem, you must always seal the cable connectors that are located outdoors using weatherproofing tape.
Installing the Link Grounding the Antenna Tsunami MP.11 Antenna Installation Guide Grounding the Antenna Direct grounding of the antenna mast, radio hardware, and surge arrestor is extremely important. NOTE: A safety grounding system is necessary to protect your radio hardware from lightning strikes and the build-up of static electricity. WARNINGS: • The antenna mast, radio hardware, and surge arrestor must be connected to the same ground, using an equi-potential bonding conductor.
Installing the Link Aligning the Antenna Tsunami MP.11 Antenna Installation Guide Aligning the Antenna Antenna alignment is a process to physically align the antennas of both units to have the best possible radio link established between them. The antenna alignment process usually is performed during installation and after major repairs.
Installing the Link Aligning the Antenna Tsunami MP.11 Antenna Installation Guide • Antenna alignment for the Base Station is useful only for a point-to-point link. • The range of the average SNR is limited to values from 0 to 48. Anything over 48 is capped at 48. • AAD is automatically disabled 30 minutes after it is enabled to remove the load of extra messages on the wireless interface. The default telnet timeout is 900 seconds (15 minutes).
Installing the Link Aligning the Antenna Tsunami MP.11 Antenna Installation Guide Antenna Cable Routing The antenna cable must be routed and fixed in such a way that installation technicians have a clear passage area. All connectors that are located outdoors must have a weatherproof seal. You are advised to seal connectors only after you have completed the final radio test.
Tsunami MP.11 Antenna Installation Guide Determining Range and Clearance 4 See the following sections: • • Determining the Outdoor Range – Maximum Range – Clearance Factor Calculations – Calculating Link Budget Determining the Outdoor Range The range of your outdoor antenna installation is closely related to a number of different factors.
Determining Range and Clearance Determining the Outdoor Range Tsunami MP.11 Antenna Installation Guide data frame due to an out-of-range situation or frame collision, the larger the number of retransmissions, the lower the throughput efficiency of your wireless link. This section explains how to determine the clearance that applies in your environment and (if applicable) the effect of insufficient clearance on the range of your outdoor wireless link.
Determining Range and Clearance Determining the Outdoor Range • Tsunami MP.11 Antenna Installation Guide If your actual clearance is less than the minimum clearance, use the diagram depicted in the following figure to determine the actual range that applies in your situation. NOTE: The Clearance Factor Diagram should be used as a rule-of-thumb for estimating the probable range in case the clearance requirements are not fully met.
Determining Range and Clearance Calculations Tsunami MP.11 Antenna Installation Guide Calculations Availability of the microwave path is a prediction of the percent of time that the link operates.
Determining Range and Clearance Calculations Tsunami MP.11 Antenna Installation Guide Procedure 1. Start with the transmit power and the number of the channel to be used in dBm. Subtract the total loss of all transmission elements between the antenna and the radio on one side of the link (dB). 2. Add the dBi of the antenna you will be using. The total is the EIRP (equivalent isotropically radiated power). 3. Determine your link budget from the Distance and Link Budget table. 4.
Determining Range and Clearance Calculations Tsunami MP.11 Antenna Installation Guide In the USA and Canada, this model radio can be installed with any gain directional antennas, as there is no Effective Isotropic Radiated Power (EIRP) limit for the application of these systems for fixed point-to-point applications in the 5.8 GHz frequency band. In other bands and in other countries, EIRP limits may apply.
