| Description | This article describes the wrong way physical position with FortiAP and the importance of following proper wireless site surveys. |
| Scope |
Every FortiAP model. |
| Solution |
The wireless networks always require a good wireless site survey, and it means that every FortiAP must be installed in the proper position, but let's see some incorrect FortiAP installations that must be avoided if it is desired to have a good wireless experience.
Do not install FortiAPs under hallways like this. Even though installing the FortiAP in the center is not recommended, users are not always in the hallways.
Do not install the FortiAPs too close together:
Verify to not have any cellphone antenna or signal booster antenna around the wireless network:
Do not place the FortiAP behind any metal object, such as pipes, rails, or behind a ceiling:
Do not install the FortiAP in a vertical position either on the ceiling or on the wall if it is an omnidirectional model.
For FortiAPs with external onmidirectional antennae, always keep them vertical, perpendicular to the ground
Do not install FortiAPs next to fluorescent lights, keep at least 1 meter and a half of separation:
Avoid using the FortiAP next to the fire system:
There are some difficult environments surrounding glass, and sometimes the glass has metal, causing high wireless disconnections, a good site survey must be done considering each material detail, the exact and correct place is mandatory, even though with a corrective site survey:
In retail stores avoid placing FortiAP devices too high from devices, between dense material walls or merchandise, or above shelves or refrigerators. Place devices above areas were WI-FI terminals are used, such as the aisle floor and between 3 to 5 meters above floor level. That is the height at which most FortiAP units are designed for optimal performance. If this is not possible consider a FortiAP model with external sector antennas. Consult with the Fortinet System Engineer for alternatives.
Avoid using 100% percent power settings, not to avoid the hidden node issue, and lower the performance, remember a small cell is going to give better performance.
• Keep working with 40 MHz and 20 MHz in some areas. • The main goal for the wireless design is for Capacity, not for coverage.
Try to avoid killing the wireless network with so many non-Wi-Fi interferers and Wi-Fi interferers, and try to avoid as much interference as possible from devices like:
In general, try to place FortiAP devices at least 1 meter (3 ft) away from any domestic electric or electronic appliance if there is no other choice for installation. |
