Figure 6 Directional antenna patterns
Omnidirectional Antennas
You typically orient omnidirectional antennas vertically, positioning them on all devices in the same
direction. Omnidirectional antennas create coverage areas that can be toroidal (doughnut-shaped) or
cardioid (heart- or plum-shaped), broadcasting to the sides much more effectively than up or down (see
Figure 7 ). In general, this is good for most office environments because you have large flat floors. However, it
can be a problem in environments with high ceilings.
