General questions about the C3205 WMIC


A MAR3200 fitted with a C3205 WMIC card (ETSI 802.11a) will be used inside a subway train. The WMIC will be connected to the ground AP through a workgroup bridge. Hereafter are a few questions about the WMIC behaviour.

1. By default, the Dynamic Frequency Selection (DFS) mechanism determines which channel to use. A preferred channel can be specified with the spacing command. It seems that it is not possible to specify a pool of channels. Is it correct?

2. The "show controllers dot11Radio 0" does not display the line indicating the number of supported simultaneous BSSID. That means that the C3205 WMIC supports a single SSID. Is it correct?

3. Which algorithm is used by the C3205 to switch to another rate when the SNR or the RSSI are decreasing?

4. Can the C3205 WMIC process the management frames at a 12 Mbit/s rate?

5. The RTS service is always activated. Is it correct?

6. What is the theoretical SNR value of each receiver sensitivity introducing the switch from one rate to the lower one?

Any answer or link to an appropriate document is welcome.

Thanks by advance,

Best Regards

1. Either auto scaning or a static channel.3. 4.9 GHz radio allos 12 mbps.5. Thats is right . Its set at 2312. Refer URL for more info

Re: General questions about the C3205 WMIC

Hi rrjoas45 ,

Thanks for your answer.

1. OK

3. Sorry, I do not understand your answer.

5. OK. Setting the threshold to 4000 can be a good way to disable (virtually) the RTS service.

Best Regards,
