1.1.4 Antenna Position and Polarization
Once the required antenna height has been determined, other factors affecting the precise
position of the AP to be considered are given below.
 Ensure that there are no other radios/antennas within 2 m (6 ft) of the wireless router. These include
other WLAN radios/antennas.
 Place the wireless router away from power and telephone lines
 Avoid placing the AP too close to any metallic reflective surfaces, such as roof-installed air-
conditioning equipment, tinted windows, wire fences, or water pipes. Ensure that there is at least 5
feet clearance from such objects
 The CPE should be aligned/matched polarization to the AP to maximize throughput.
1.1.5 Radio Interference
The avoidance of radio interference is an important part of wireless link planning. Interference
is caused by other radio transmissions using the same or an adjacent channel frequency. You
should first scan your proposed site using a spectrum analyzer to determine if there are any
strong radio signals using the 802.11a/n channel frequencies. Always use a channel frequency
that is furthest away from another signal and change the physical location of the device.
1.1.6 Weather Conditions
When planning wireless links, you must take into account any extreme weather conditions that
are known to affect your location. Consider these factors:
