Details on deployment and design, limitations and capabilities, and basic theories of antennas as well as
installation scenarios, regulatory information, and technical specifications are addressed.
Table 6 summarizes the horizontal and vertical beamwidth for Cisco antennas.
N-Connectors
All antennas are equipped with N connectors.
AP1522 has three separate N-connectors to attach two 2.4-GHz antennas, and one N-connector for a 5-
GHz antenna.
AP1524 has five N-connectors to attach three 2.4-GHz antennas and one N-connector for the 5.8-GHz
antenna, and one N-connector for the 4.9-GHz antenna.
Each radio has at least one TX/RX port. Each radio must have an antenna connected to at least one of its
available TX/RX ports.
Antenna locations for 5.8 GHz, 4.9 GHz, and 2.4 GHz are fixed and labeled.
Figure 9 shows antenna placement for a two-radio cable mesh access point.
Figure 10 shows antenna placement for a two-radio fiber mesh access point.
Figure 11 shows antenna placement for a three-radio fiber mesh access point.
