According to the following table you will have the idea about the relation between antenna dBi connecting distance and Data rate for example the bridge with 17dBi antenna could operate well under 6 Mbps data rate within 17 KM This table is for reference only The actual connecting range might vary upon the installation environment Data Rate Maximum Distance Maximum Distance 17dBi Antenna 23dBi Antenna 6Mbps 17 72 30 79KM 9Mbps 1682KM 2936KM 42Mbps 16 07KM 28 07 KM 14 64 2560KM Table 1 Evaluated Maximum Distance 6 3 Planning Radio Path For the wireless communication the Line of Sight LOS will be the major issue over building up the wireless link This evaluated procedure is to reduce the obstructions and to avoid the multiple path signal degrading the communication quality The first requirement is the Line of Sight LOS between the both sides Antennas The radio line of sight concept is the area along the radio linking path through which is the bulk of the radio signal power travels The area is known as the first Fresnel Zone of the radio link For the radio link it should avoid to be affected by obstacles in this path including the ground within 609 of the first Fresnel Zone The following figure illustrates the concept of a good radio line of sight 38 Visual Line of Sight Radio Line of Sight Picture 24 Line of Sight LOS If there is any obstacle in the radio pa

35. s the AC power to the bridge system 7 2 5 General Antenna and Safety Tips When installing an antenna follow these general tips For most elevated antenna installations we recommend you to ask the professional installers for proper installation and safety For the safety reasons you are recommended never to touch a high gain antenna when it is transmitting or point it at any part of your body Please follow carefully the instructions with your antenna Keep antennas away from metal objects obstructions heating and air conditioning ducts large ceiling trusses building superstructures and major power cabling runs Use a directional antenna when you establish a link between two buildings A directional antenna must be properly aligned to the point at the other antenna Locate an omnidirectional antenna in the middle of the desired coverage area if possible Place the antenna as high as possible to increase the coverage area Outdoor antennas should be mounted at a sufficient height to prevent the radio path from above the obstructions such as trees and buildings Antenna towers should keep a safe distance from overhead power lines The recommended safe distance is twice the tower height Use the special ground rods and follow the National Electrical Code for the outdoor antenna and tower grounding properly To prevent water from entering into the antenna cable and be sure to seal all external cable connector
36. s using commercial products just like coax compatible electrical tape and Coax Seal 45 7 2 6 Basic Antenna Alignment When you use directional antennas to communicate between two bridges you must manually align the antennas for proper bridge operation Directional antennas have greatly reduced radiation angles The radiation angle is approximately 25 to 30 degrees and the parabolic dish antennas radiation angle is approximately 12 5 degrees You can use the link testing tool to help measure the alignment of two antennas after the bridges are associated The link testing tool provides you information you can use to gauge the alignment 7 2 7 ESD Protection The ESD electrostatic discharge can damage the electronic components The ESD can cause latent damage that results in premature failure even if components remain function The equipments must be properly grounded The technical people always need to wear the proper ESD grounding straps and make sure the ESD grounding strap connecting to the ESD connector during equipment installation maintenance and repairs 7 2 8 Review the Installation When you finish installing the bridges and aligning the Antennas you need to secure all cable connection is tight properly secure the Antenna mounting set is tight after the alignment Check the cable connection is between the Antenna and the bridge is tightly Make sure the grounding strip is properly connected to the Ground Check the cabl
