Introduction to the 2.4- and 5-GHz Radios

The Cisco Aironet 2.4- and 5-GHz radios are designed for use in the Cisco Aironet 1200 Series Access Point. Both radios offer industry-leading range and performance and superior dual-band technology.

The 2.4-GHz radio is an IEEE 802.11b- or g-compliant 2.4-GHz radio card that is installed in the access point's mini PCI card slot. The card is located beneath an access door on the bottom of the access point.

The 2.4-GHz radio card is available in two versions:

IEEE 802.11b mini-PCI radio card (802.11b radio)

IEEE 802.11g mini-PCI radio card (802.11g radio)

Requires Cisco IOS Release 12.2(13)JA or later

The upgrade procedures are identical for both versions.

The 5-GHz radio is a IEEE 802.11a-compliant 54-Mbps 5-GHz radio module with that is inserted into the access point's cardbus slot. The cardbus slot is located on the end of the access point and is protected by an access cover when the radio module is not installed.

There are two versions of the 5-GHz radio: integrated antenna and connectorized. The integrated antenna version contains an articulated antenna paddle. The connectorized version contains two RP-TNC connectors that accept external antennas.

The 5-GHz radio module is available in three versions:

Low power IEEE 802.11a radio module with integrated antenna (RM20A radio module)

Enhanced IEEE 802.11a radio module with dual integrated antennas (RM21A radio module)

Requires Cisco IOS Release 12.3(2)JA or later.

Enhanced IEEE 802.11a radio module with dual external RP-TNC antenna connectors (RM22A radio module)

Requires Cisco IOS Release 12.3(2)JA or later.


Tip If you are upgrading to an 802.11g radio or an RM21A or RM22A radio module, make sure you are running the correct Cisco IOS version before you install the radio or module. If your access point is running an earlier version, it will not recognize the radio or module and continually boot.


All 5-GHz radios incorporate an Unlicensed National Information Structure (UNII) radio transceiver operating in the UNII 5-GHz frequency bands.

The upgrade procedures are identical for either version.
