To avoid RF interference: 
• Remove these devices from the immediate area where users are working. 
Something as simple as a Bluetooth enabled mouse may cause transmission 
interruptions. 
• Keep the FortiWiFi-50B AP and wireless devices at least 10 feet away from 
appliances such as microwave ovens and cordless phones. 
• If you must have a cordless phone, select one that does not use the 2.4GHz 
frequency range. 
• Consider more FortiWiFi-50B APs to help strengthen the signal. The weaker 
the signal, the slower the transmission will be as it tries to compete against 
other wireless devices. 
• Set a channel that users and FortiWiFi-50B APs will specifically use can 
improve signal quality. 
Using multiple access points
If you cannot avoid some of these impediments due to the shape of the office or 
building materials used, you may need to use multiple FortiWiFi-50B APs to help 
distribute the radio signal around the room. 
 shows how positioning two 
FortiWiFi-50B APs within a uniquely shaped office space helps to distribute 
signals around the area. 
Figure 14: Using multiple APs to provide a constant strong signal.
This sample office has washrooms, a stairwell and an elevator shaft in the center 
of the building, making it impossible to use a single FortiWiFi-50B AP effectively. 
The elevator shaft and multiple metal stalls in the washrooms can cause signal 
degradation. However, placing a FortiWiFi-50B AP in opposite corners of the 
office provides maximum coverage. 
When using multiple APs, each FortiWiFi-50B AP should be set to a different 
channel to avoid interference in areas where signals from both FortiWiFi-50B 
devices can be received.
