Catwalk/Ceiling
• Usually Utilizes Patch Designs
• Higher Ceilings Usually Require Higher Gain
• Higher Gain = Smaller Beamwidths = More AP Density and Smaller Cells
Wall Mount/Pole Mount
• Variety of Gain and Beamwidth Options to Customize Coverage Zone
Under Seat
• Usually Utilizes a Very Low Gain Omni
• People and Surroundings Create RF Barriers
• May Require Enclosure for Physical and Environmental Security

Dual Polarity reduces signal collision
Reduced signal collisions allow the radio to send and receive data faster and more efficiently
Dual Polarity does not change ANYTHING on the radiation pattern (coverage area), it just modifies they way the sine wave travels

Selecting the Right Antenna
H-PLANE
• Looking from the Sky
• WIDTH of the pattern
V-PLANE
• Looking at a Profile
• HEIGHT of the pattern

Where do Radiation Patterns Come From?
AccelTex Antennas are tested at ONE
frequency and ONE element at a time in
an anechoic test chamber
