A site survey involves the following tasks:
Determine the coverage objects and requirements.
Obtain the layout of the areas to be covered from the customer.
Learn about the network topologies in the areas.
Obtain contact information of customer's onsite technical personnel.
Identify device installation positions and power supply mode (completed by the asset management personnel of the property management).
Determine the positions to install APs, power cables, and network cables with the asset management personnel. Check whether Internet access resources are available.
Determine whether a distributed antenna system (DAS) is required according to the coverage objectives. If a DAS is available, obtain the DAS design drawings from the customer. If not, ask the carrier whether a DAS is required. If a new DAS needs to be established, determine the positions of antennas with the asset owners.
Check the construction materials and calculate signal loss.
Check for interference sources.
Collect the following information during a site survey:
Layout of the coverage areas
Mark the cabling routes and device installation positions on the layout drawings.

Building arrangement and structure in the coverage areas
Calculate signal coverage distance of APs based on building arrangement and structure.

Number of users and required bandwidth
Calculate the network capacity based on the number of users and bandwidth required.

Device installation positions
Topology and bandwidth resources of the wired network
Whether there are sufficient optical fibers and wired network resources to transmit WLAN data
Signal losses caused by walls, doors, windows, and other construction materials
Locations and signal strengths of interference sources
