    6. Planning Linkage 6.1 Site Survey You need to consider the following operating and environmental conditions when performing a site survey: Data rates – The sensitivity and the radio range are inversely proportional to data rates. Therefore, the maximum radio range is achieved at the lowest workable data rate, and a decrease in receiver threshold sensitivity occurs as the radio data rate increases.

  • Page 38: Data Rate

    6.2 Data Rate 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.
  • Page 39 Picture 24 Line-of-Sight (LOS) If there is any obstacle in the radio path, it may still be a radio link but the quality and the signal strength will be affected. Ensuring the maximum clearance from objects on a path is important to locate the antennas and the height.

  • Page 40: Antenna Height

    6.3.1 Antenna Height The reliable wireless linkage usually depends on the both sides’ antennas for a clear radio line of sight. The minimum height is up to the link distance, obstacles that may be in the path, topology of the terrain, and the curvature of the earth (for links over 2 miles).

  • Page 41: Antenna Types

    For example, the wireless link between the building A and the building B is located three miles (4.8 km) away. There is a tree-covered hill in the mid-way. From the table above, it can be seen that for a three-mile link and the object clearance required at the mid-point is 5.4 m (17.6 ft).

  • Page 42: Weather Affection

    6.3.4 Weather Affection The weather plays one of major matters to the antenna performance for the wireless communication. The raining day, the lightning day, the cloudy day, or the windy day will make a quite big impact to the both side antennas over the communication results.

    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.
