I dont know if this has been answered as yet.

How would you use a R52nH with a RB433AH and a dual feed 5.8ghz dish to setup a full duplex link?
Would you use 1 card per feed or both feeds onto one card?
Would the card auto do full duplex or have to use OSPF to get best speed and duplexing?

Please assist.....

All wireless cards is half-duplex. Use two wireless cards for full duplex.

Not entirely accurate.
802.11n can receive on one antenna while transmitting on the other.

Does this sound like full duplex to you?

The setup on the R52nH is very confusing. I want to attach a poynting dual polarized 5.8gh dish to one of these cards on both pigtails. I am hearing mixed opions regarding this. Will it run faster if I use 1 per pigtail or won't it matter,, but then must I use OSPF to run the full duplex link?

I repeat all 802.11a/b/g/n wireless cards is half duplex. It transmit in one time and receive in other time not in same time. Check electrical scheme any of this cards.

Anything with the prefix 802.11xx is half duplex in nature.

I agree that anything 802.11 is half duplex by nature.
With that said;
When I can do a routerboard to routerboard TCP speedtest over N and accomplish 90Mbps UP and 90Mbps Down simultaneously,
then I would have to make a statement that it is purdy dang close to full duplex for the likes of me.

With queues I can ensure that the 90Mbps in either direction is never exceded, which should then (somewhat) guarantee that I have a 90Mbps full duplex connection (of sorts).

edit: I am always game for competetively priced, well performing products.

Even if it works "almost as fast as full duplex," it is still not full duplex by definition unless it sends and receivers at EXACTLY the same time.

What you are saying is no different than taking a 15 Mbps 802.11a link and calling it 5 Mbps full duplex.
Sure, that's what the customer will feel, but it is not technically correct.

Pay attention:
1 radio card - half duplex
2 radio cards - full duplex

Given the nature of Internet traffic, I'd go for a faster half duplex link unless we are talking about a specialized VoIP or real time application.

Technically yes, I know this.
I have reverse engineered integrated curcuits, so TECHNICALLY I am VERY aware of what the limitations are.

When some one asks for 100Mbps full duplex, they are usually asking for 100Mbps Symetrical.
And much of the time they are only interested in the TECHNICAL details behind this ONLY for the purposes of achieving a bidirectionally balanced data rate.

The pupose of the forum is to help others, IT is not a pissing match to see who can go further.

I have seen symetrical datarate connections on half duplex outperform symetrical datarate connections on full duplex.

When using unlicensed wireless devices you can pretty much throw any semblance of TRUE duplex out the window, so for you TECHNICALLY astute, have that.


I may very well be finished helping in this forum, as this whole thead has turned into a pile of bull shit,
as may other theads before.

I thought some Motorola gear was full duplex? Maybe I'm wrong, can't say I used it much.

You wrote "802.11n can receive on one antenna while transmitting on the other" which is simply not true.
You and I know that you did not mean exactly what you wrote but some other readers don't.

If you are being corrected, it is not beause we think you don't know - it is to prevent others from misunderstanding or getting confused.
There is nothing for you to be upset about. We are all just trying to spread correct easy to understand information.

Truth of matter is that full duplex can only TRUELY be accomplished with ASIC or discrete logic.
Once a CPU is introduced, TRUE duplex is not possible, but EXTREMELY close.

That is the true technical fact of the matter.

it is just matter of definition.

Full duplex usually is referred to device that can transmit and receive at the same time, literally. When act transmission or receiving of signal does not interfere with each other. If at the time of transmission or receive you cannot do the other, it is considered half duplex. That is, if we agree what duplex is.

No, it's called "half duplex"
