Finding the most effective place to install an access point can sometimes be a challenge. The following ideas will provide the optimal network performance.
First and foremost, we want to avoid physical obstructions whenever possible. Any barriers along the line of sight between customers and the access point will degrade the WiFi signal. Plaster or brick walls tend to have the most negative impact. Obstructions tend to reside closer to floor level. Therefore, installing the access point on or near the ceiling is typically your best bet to maximize the network signal.
Install at least 3 feet away from other appliances that may transmit signals in the same frequency range or cause electrical interference such as; microwave ovens, cordless telephones, electric fans, other motors, and fluorescent lighting.
Avoid reflective surfaces whenever possible. Some WiFi signals literally bounce off of windows, mirrors, metal file cabinets and stainless steel counter-tops, lessening both network range and performance.
Strive to install the access point in a central location. We want to have the access point as close to customers as possible.
If the best location is only marginally acceptable, consider adjusting the access point's antennas to improve performance. Re-pointing the antennas can fine tune the WiFi signal.
If using these guidelines you are still finding that some areas of the establishment aren't receiving a good signal, we might want to consider adding another access point or installing a WiFi repeater to boost the range of the existing access point.
