RF Survey
When conducting an RF site survey, we consider these general steps:
1. Visual inspection of the area– Walking through the area does reveal facts about the site plan. This is a good time to note any potential barriers that may affect the propagation of RF signals. For example, a visual inspection will uncover obstacles to RF such as metal tank towers and mountains.
2. Identification of the user areas is a good habit to mark the areas of fixed and mobile users on the diagram as well as illustrate where mobile users may roam.
Determine Preliminary Access Point Locations
3. Location of wireless users and range estimations of the wireless system used, approximation of the locations of spots that will provide adequate coverage throughout the user areas will be possible. Planning for some propagation overlap among adjacent access points may seem necessary when the number of subscribers grows.
Mounting locations should be considered, which could be ground or rooftop towers. Recognizing suitable locations for installing the tower, antenna, cables, and power line is a vital task in any access point location phase.
4. Data gathering Once the surveyor is satisfied that the planned location of access points will provide adequate coverage, data regarding site installation peripherals, covered spots, and barriers should be gathered. Panoramic photos of site boundaries with steps of 45 degrees as well as photos in the direction of antenna azimuth predictions should be taken to provide an asset for the site planner. Such photos must be orderly and placed in the site documentation. Data regarding existing and/or reusable site installations should also be included in the document. Any reusable container, room for indoor equipment, or existing tower must be listed. The survey document should also contain information about the area, environment, site address, ways to access the site place, and available access time to reach the place.
