5.0-GHz (802.11h) Radio Features
The 5-GHz radio supports only 20-MHz channelization. In addition, the 5-GHz radio supports Dynamic
Frequency Selection (DFS) and Transmission Power Control (TPC) in the ETSI and FCC regulatory
domains.
For more information about DFS and TPC, see Radio Channels and Transmit Frequencies at
http://www.cisco.com/en/US/products/hw/routers/ps272/products_installation_and_configuration_guid
es_list.html.
Note 802.11h is supported only in the ETSI regulatory domain.
Note By default, the C3205 WMIC uses the right antenna to receive and transmit data.

5.0-GHz (802.11h) Channels

The 5.0-GHz (802.11h) radio in the Cisco 3200 Series router (currently available as the Cisco 3205
WMIC) supports the following channels and frequencies in the ETSI regulatory domain:
• 5.250 GHz to 5.350 GHz: 5260 MHz (52), 5280 MHz (56), 5300 MHz (60), 5320 MHz (64),
• 5.470 GHz to 5.725 GHz: 5500 MHz (100), 5520 MHz (104), 5540 MHz (108), 5560 MHz (112),
5580 MHz (116), 5600 MHz (120), 5620 MHz (124), 5640 MHz (128), 5660 MHz (132),
5680 MHz (136), 5700 MHz (140). (Channels 52 through 140 are ETSI outdoor channels.)
North America customers can use only the following frequencies in the 5.725-GHz to 5.850-GHz band:
• 5745 MHz (149)
• 5765 MHz (153)
• 5785 MHz (157)
• 5805 MHz (161)
• 5825 MHz (165)
Note By default, the C3205 WMIC performs automatic channel selection on the radio interface. For more
information about configuring a channel on the radio interface of the Cisco 3205 WMIC by using the
command-line interface (CLI), see the “Configuring the Radio Channel or Frequency for the C3205
WMIC” section in the Radio Channels and Transmit Frequencies document. To see Dynamic Frequency
Selection (DFS) statistics, use the show interface d0 dfs command.

Throughput

The throughput is a minimum of 16 Mbps half-duplex at one mile line-of-sight range for a

20-MHz-wide channel. The range performance is dependent on output power, antenna gain,

path loss, and other factors.

The following are range performance estimations:
• 6 Mbps at 10 kilometers (6 miles) at 30 dBm equivalent isotropically radiated power (EIRP)
• 1 Mbps at 30 kilometers (18 miles) at 30 dBm EIRP
