Line Of Site (LOS) Survey
The ultimate goal of LOS survey is to have MW connectivity between the two sites to ascertain the Line of Site clearance. The LOS survey is carried out physically checking the terrain between the hop and selecting the sites for acquisition. The survey is highly critical because any failure in LOS can lead to a delay in project and a subsequent loss on account.
LOS survey is carried out in the following steps:
- Collect Nominals of proposed site and those of the nearest locations to which customer proposes the LOS connectivity & Verification
- Record latitude, longitude, building data, obstruction data and surrounding terrain data on the LOS Survey template
- Generate LOS Path Profile for the proposed Link using Path Loss 4.0
- Generate LOS report for the proposed Link using Path Loss 4.0.Conduct physical survey of the hop to identify any field obstructions and verify the LOS path profile
RF / LOS Survey:-
With wireless systems, it's very difficult to predict the propagation of radio waves and detect the presence of interfering signals without the use of test equipment. Even if you're using omni-directional antennas, radio waves don't really travel the same distance in all directions. Instead walls, doors, elevator shafts, people, and other obstacles offer varying degrees of attenuation, which cause the Radio Frequency (RF) radiation pattern to be irregular and unpredictable. As a result, it's often necessary to perform a RF site survey to fully understand the behaviour of radio waves within a facility before installing wireless network access points.
The ultimate goal of a RF site survey is to supply enough information to determine the number and placement of access points that provides adequate coverage throughout the facility. In most implementations, "adequate coverage" means support of a minimum data rate. A RF site survey also detects the presence of interference coming from other sources that could degrade the performance of the wireless LAN
The need and complexity of a RF site survey will vary depending on the facility. For example, a small three room office may not require a site survey. This scenario can probably get by with a single access point located anywhere within the office and still maintain adequate coverage. If this access point encounters RF interference from another nearby wireless LAN, you can likely choose a different channel and eliminate the problem.
A larger facility, such as an office complex, apartment building, hospital, or warehouse, generally requires an extensive RF site survey. Without a survey, users will probably end up with inadequate coverage and suffer from low performance in some areas. You certainly wouldn't want to relocate and add access points to the facility after installing and interconnecting 20 access points or more.
