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.
