Single Or Dual-Radio Operation; Antennas Supported; Ethernet Port - Cisco 1242AG - Aironet - Wireless Access Point Hardware Installation Manual

Chapter 1 Overview

Single or Dual-Radio Operation

The 1242AG access point supports simultaneous radio operation using a 2.4-GHz 802.11g radio and a
5-GHz 802.11a radio. The 1242G access point supports a single 2.4-GHz 802.11g radio. Each radio uses
dual-diversity integrated antennas.
The 5-GHz radio incorporates an Unlicensed National Information Infrastructure (UNII) radio
transceiver operating in the UNII 5-GHz frequency bands. The 802.11g radio is called Radio0 and the
802.11a radio is called Radio1.

Ethernet Port

The auto-sensing Ethernet port (see
your 10BASE-T or 100BASE-T Ethernet LAN. The access point can receive power through the Ethernet
cable from a power injector, switch, or power patch panel. The Ethernet MAC address is printed on the
label on the back of the access point (refer to the
