Use of a high gain omnidirectional antenna should be avoided. This type of antenna will increase the size of the cell and the 
number of users that will be sharing the bandwidth. Higher gain in an omnidirectional antenna design generally means increased 
horizontal beamwidth with a decrease in vertical beamwidth. This effect will be more pronounced as the ceiling height increases.

• 

The low-gain omnidirectional antenna has less horizontal coverage and in an auditorium will have less floor coverage than a 
high-gain antenna. This supports the goal of small channel and small floor size and it will serve to limit the number of users in 
the coverage area, effectively managing client-based co-channel interference. The low-gain antenna will also provide a better 
quality signal. 

Cisco Indoor Access Points with Internal Antennas

Cisco APs with internal antennas [Table 6] have optimized coverage patterns for consistent RF distribution. The coverage 
patterns for all currently shipping APs optimized for ceiling mounting, however, will perform well mounted on a wall, under a seat, 
or beneath the floor as well.

Note: The same integrated antennas are used on these devices but AP-1040 only has two elements per band.
