The ultimate goal of a RF site survey by Aster is to acquire ample information to determine the number and placement of access points that allows optimal coverage throughout the facility. The site survey is a physical survey of the customer's premises or proposed 'Hot-Zone' to identify the best possible locations to install backhaul equipment and access points to ensure 100% wireless coverage, along with maximum performance, within the desired area.
When considering the use of wireless equipment, it is extremely difficult to predict the propagation of radio waves and detect the presence of interfering signals without the use of specialized test equipment. Even if you are using omni-directional antennas, radio waves do not travel the same distance in all directions. 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, one should have an RF site survey performed to understand fully the behavior of radio waves within a facility or outdoor site before installing any wireless devices. The goal of an RF site survey is to gather enough information and data to determine the number and placement of access points that will provide the coverage required. Coverage required usually means the support of a minimum data rate in a given area. An RF site Survey will also detect the presence of radio interference coming from other sources that could degrade the performance of the wireless system.
The need and complexity of an RF site survey will vary depending on the size of the facility or site and the work that is to be accomplished. A site survey is a good idea for the use of any wireless device because without a survey, users could end up with inadequate coverage and suffer from low performance in some areas. The purchase of wireless equipment is no small expenditure, so it is best not to leave any portion of the project up to chance.
To ensure the accuracy of the final site survey report that ACCORD delivers, only the latest and most sophisticated equipment is used to check for Signal Level, Noise Level, and more importantly SNR (Signal to Noise Ratio). After the site survey, we will design the network infrastructure to fit your specific needs. Using the information obtained during the site survey, ACCORD will design a wireless network infrastructure for your specific environment that will ensure complete propagation to each of your devices.
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 behavior of radio waves within a facility before installing wireless network access points.
