Good day...
I have look around wiki and asked Google....

But it's seem no explanation about the 802.11n MCS7 and MCS0....
And, it's possible this 11n card can just running on only and RF port but no both....

It would appear that you didn't look too hard on Google. I'll define the MCS's for you and the answer to your second question has been asked several times already. 802.11n is MIMO by definition, Multi Input Multi Output, thus, you can't run only one RF port and have 802.11n. The card will work with a single port if you restict the card to a/b/g operation. You really should do a little more research yourself but I'm feeling like a nice guy tonight so I'll answer your questions.

The explanation about MCS7 and MCS0 you requested is that MCS stands for Modulation and Coding Scheme. According to the latest draft standards MCS0-15 support is required by compliant AP's and MCS0-7 support is required by compliant clients. Since 802.11n uses several spatial streams, modulations, coding rates, guard invervals and channel widths there needs to be a simple way to state everything that is going on with a radio link in one simple way. Thus, the MCS system was developed which assigns a number to every possible combination of the technologies that 802.11n can deploy. You can look everything up for yourself if you use Google a little better than you did before your last post but I will define MCS0 and MCS7 since you asked specifically about those two.

MCS0 uses BPSK modulation, 1/2 coding rate, and a single spatial stream. These translate to a 20 MHz channel data rate of 6.5 Mbits at a 800ns guard interval and 7.2 Mbits at a 400ns guard interval. With a 40 MHz channel you'll have 13.5 and 15 Mbit data rates respectively. MCS7 uses a 64-QAM modulation, 5/6 coding rate, and also a single spatial stream. The date rates would be 65, 72.2, 135 and 150 mbits at 800 and 400ns, 20 and 40 MHz respectively.

Thanks guy...

Bad attitude and bad information too. Now we know that single chain 11n devices do exist. Since the lower MCS rates require only a single stream, you could have guessed as much.

There is a good MCS rate table here: http://en.wikipedia.org/wiki/IEEE_802.11n-2009

Keep tryin' Expunge.

Good job on bringing back a 3 year old thread to fuss at someone for being a little less polite than you thought they should be.

I know this is a 3 yr old thread but I still don't understand one thing. I've looked at various charts that mention MCS7 and MCSO on the cAP lte. But it doesn't show a throughput.
The details in the listing show a max data rate of 300M but the details below state 54M at 18dbm and then no data rates for MCS7 or MCSO. So will it or won't it do a max throughput of 300M?
