How to do Wireless Hotspot Site survey?
As the site survey stands for a physical site visiting to check all the necessary requirement projection to done the project. For any types of project site survey is needed to avoid all the issue come during the deployment of the project. So here in this post, we are talking about wireless feasibility and site survey to create problem-free wireless networks.
In every wireless network where more than 2-3 access point going to use site survey must be done to check interference and covering of area proper with strong signal strength. For hotspot installation site survey required to check the complete area covering by Wi-Fi hotspot, total con-current user and total speed of Wi-Fi internet provided to users.
Site Survey: A professional installer is needed for optimal results. So in this post step to step given site survey done for hotspot and point to point, point to multi point network connectivity. Read complete post to know How to do Wireless Site survey?
These are the steps that are performed
1. Obtain a facility diagram in order to identify the potential radio
Site survey important part is a diagram of the hotspot deployment process to get the proper signal strength and right device to success hotspot deployment.
2. Frequency (RF) obstacles
Frequency obstacles cannot see visually but it can be detected and analyze with Wi-Fi signal Analyzer and Wi-Fi heat-map software tools to avoid inference and over lapping of RF frequency and proper channel planning.
3. Visually inspect the facility to look for potential barriers or the propagation of RF signals and identify metal racks.
Most important part of the hotspot site survey has visited the site and inspect visually about construction and any heavy obstacle in Wi-Fi signal. Check the building wall type wood construction or glass construction or concrete construction to get a proper covering of Wi-Fi Signal each and every corner.

4. Building Structure
Hotspot site survey depends on building structure because we have to work out how building structured and what can be proper Access Point mounting design to get proper signal strength everywhere in the building.
5. Type of wall
Type of Wall should not be properly inspected can be the reason of failed hotspot site deployment. So proper inspect and check wall is glass work wooden or concrete construction.
6. Type of user either laptop or PC
Discuss with the client about user type will Laptop or PC. User load and the total number of the user must be clear to get proper Access point according to requirement.
7. Throughput requirement
What will be total throughput requirement depend on bandwidth provide to hotspot user? Throughput requirement will give about Access Point capacity needed for the hotspot.
8. External interference
Check external interference on hotspot area with using inside and third party free Wi-Fi analyzer software to get existing frequency inherence in that area.
9. Ethernet connection source from the server
Connection source from the server is most important because its depend on how hotspot system will connect with server and what will be distance and length of connection it to avoid loss and frequent breakdown due to physical damage of cable and connectors.
HotSpot Site Survey? / How to do Wireless Site survey.
Hotspot means creating a Wi-Fi zone in any location to get user connected with internet without any wire connection. As we already describe what is the important step to get a proper site survey for Hotspot, Point to Point and Point multi point wireless connectivity. About Hotspots site survey keep in mind always given steps to inspected before deploying any project and site to avoid frailer of the project.
- Identify the location to be WiFi-ed.
- Based on that determine preliminary access point (AP) locations.
- Check for the nearest available power socket.
- Check for nearest Ethernet point from the switch room.
- Identify the client base.
- Identify the coverage area. Based on that derive the minimum number of access points required.
- Document the findings.
- Record the locations and the log of signal readings as well as data rates at outer boundaries.
The Wireless Point To Point / Point to Multi-Point Site Survey
PTP full form is Point to Point and PTMP means Point to Multi Point. PTP means one Location connected directly to the second location with Wireless connectivity called Point to Point connection. PTMP means one Point (Location) connected to Multi Point (Location) called PTMP Wireless connectivity.
Before doing any point to point and point to multipoint site survey must be done to confirm of both location proper feasible and what necessary requirement need to make it feasible with required throughput as needed.
1: Elevation of installation points
Visit the site with GPS device and get the co-ordinate and both location. GPS will show both side Elevation height from sea level.
2: Line of sight
The line of sight also call feasibility of wireless connectivity and it should be clear to travel signal one location to other location to get wireless connectivity.
3: Type of usage
Point to Point and point Multipoint connectivity usage must be clear before suggesting any hardware. Confirm that Point to Point connection for CCTV camera, Internet, or any other type application.
4: Number of systems to connect
The number of systems to connect should be pre-decided because the total number of user will depend on Wireless throughput.
What Application will use with the point to point and point to multipoint wireless connectivity should confirm.
6: Throughput requirement
Throughput requirement should be calculated according to the total number of user will use the connection in the network using the same point to point connectivity. And its also depend on what type of application should work on wireless connectivity. Exp: CCTV with wireless need more throughput to get live streaming.
7: External interference
External interference will disturb point to point connectivity and throughput so must be checking what frequency already running and which on free.
8: Use GPS to find the latitude, longitude, and elevation
Use GPS device to get both location co-ordinate and check the site survey and feasibility test in Google earth to see the requirement of height needed to Line of sight.
9: Observe if there are any obstructions in the form of Tall hills, buildings and vegetations using Google earth.
10: Fresnel-Zone clearance should be there.
