Altitude 4700 Series Access Point Installation Guide 15
There are two 802.11an/802.11bgn dualband radios in an Altitude 4700 Access Point for
WLAN operation: labeled as R1 and R2. Radio R1 is set as an 802.11bgn radio (2.4 GHz)
and radio R2 as 802.11an radio (5 GHz). The frequency band of these radios cannot be
changed for WLAN operation. However, radio R1, radio R2, or both can be configured
to a Rogue AP detector or a WIPS sensor. When the radio (R1 or R2) is in the Rogue AP
detector mode or the WIPS sensor mode, it can cover both 2.4 GHz and 5 GHz band.
If the radio is configured to perform dual-band scanning, then an appropriate dual-
band dipole antenna should be used for optimum coverage.
Each radio requires three antennas to achieve optimum MIMO performance for WLAN
operation: R1-A/R1-B/R1-C for radio R1, and R2-A/R2-B/R2-C for radio R2. The third
radio in Altitude 4750 is used only as a WIPS sensor and cannot be converted for
WLAN operation.
Mounting the Access Point
An Altitude 4700 Series Access Point can attach to a wall, mount under a suspended T-
Bar or above a ceiling (plenum or attic) following the same installation instructions.
Choose one of the following mounting options based on the physical environment of
