Altitude 4511 Access Point Antennas
The Altitude 4511 Access Point contains two internal (embedded) dual-band antennas
supporting both the 802.11bgn (2.4 GHz) and 802.11an (5.0 GHz) bands. No customer
assembly or antenna orientation is required.
The Altitude 4511 Access Point radio can transmit on one or two antennas depending on
the operating mode. The radio can receive on one or two antennas as well. The data rates
supported are different in each case.
LED Indicators
An Altitude 4511 Access Point has two LED activity indicators on the front of the unit.
The LEDs provide a status display indicating error conditions, transmission, and network
activity for the 5 GHz 802.11a/n (amber) radio or the 2.4 GHz 802.11b/g/n (green) radio.
