Chapter 6 Wireless Mobile Interface Cards 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 Modulation Table 6-11 lists the supported 5.0-GHz (802.11h) modulations and data rates.
