1. Antennas Omnidirectional antennas are connected to the access point via short attached cables The antennas can be mounted to a ceiling and provide a large circular coverage area These antennas can be used both indoors and outdoors see Table 3 for specific details for usage and are typically mounted on a ceiling or mast pole Examples of places in which omnidirectional antennas are useful include warehouses manufacturing floors and other large areas as well as outdoor seating areas such as caf s or central gather ing places for students Omnidirectional antennas can also be used to provide good coverage in a retail environment both inside and outside as well as in areas where trucks or police cars park to upload data Table 3 Indoor Outdoor Omnidirectional Antennas for Cisco Aironet 802 11n Access Points 2 4 GHz Omnidirectional Antenna Part Numbers AIR ANT1728 3 Quantity Required Description Ceiling mount indoor outdoor Mast mount indoor outdoor AIR ANT2506 Ceiling mount indoor AIR ANT2430V R 5 GHz Omnidirectional Antenna Part Numbers AIR ANT5160V R Quantity Required Description Quantity Required Description 1 Ceiling mount 2 5 dBi 2 4 indoor GHz 3 5 dBi 5 GHz Directional Antennas Directional antennas redirect the signal they receive from the access point Redirecting the signal has the effect of providing more energy in one direction and less energy in all other directions2.
