Cisco Aironet 1250AG Series Access Point Hardware Installation Guide
OL-8247-01
Chapter 1 Overview
Hardware Features
Single or Dual-Radio Operation
The access point supports single or simultaneous dual radio operation using 2.4-GHz 802.11b/g radio
and 5-GHz 802.11a radio modules. Each radio uses dual-diversity integrated antennas. A blank module
is supported for single radio access point configurations.
The access point supports upgrading of a radio module with a 802.11n radio module (future availability).
The 802.11n radio module will be available when the standard is ratified.
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.
Note In Cisco IOS Release 12.3(8)JA and later, the access point radios are disabled by default, and there is no
default SSID. You must create an SSID and enable the radios before the access point allows wireless
associations from other devices.
Antennas Supported
Table 1-1 lists the supported access point antennas.
Caution The access point, the antennas, and the power source (power injector or power module) must be located
in an indoor environment.
