I am planning to use bulletM2HP along with 24 dBi parabolic antennas to create a link of a Km distance and need a minimum throughput of 30 mbps for a video streaming.
I want to make sure whether using a normal 24dBi antenna which I used for 802.11g based devices will work properly with bulletM2HP as this one is 802.11n based. Can anyone please confirm?
Is so how does it work properly as my understanding says 802.11n uses MIMO and in this case I am using only one antenna?

Hi, you can get more than 30Mbps depends of distance and interference.
The Bullet M it's based on N but with single change so the modulation it's half 150Mbps Air Rate so typical bandwidth can achieve it's like 90Mbps single way with optimum environment.

Are you using TCP/IP or UDP for the video?

I have done a link test of the Bullet M2 and pulled one way with multiple streams 70mbps but if you have one single source you will only see about 24mbps.
May be using Rocket M with dual-polarity antennas ?

I have a silly/newbie question. A equipment supplier told me that at much he has only seen equipment only capable of sending 4 E1s through a wireless link...........correct me if i'm wrong, but aren't 4E1 aprox 8Mbps? but with a good pair of Ubiquiti I can get like 30Mbps of throughput, so why is that kind of equipments so expensive if can get better results with ubiquiti that costs much much less?? or Am i wrong and i'm comparing apples to oranges?

He would be very surprised to see Ceragon or Dragonwave links hitting 400 Mbps per carrier, 800 Mbps per channel with dual-polarization antenna-pair or 1.6 Gbps per system consisting of two dual-polarization links, 4 carriers.

thank you for your answer, that was exactly what i was thinking!!!. I think he only wanted me to buy what he was selling, so he told me that.....

I am using TCP/IP for the video.
I am actually aggregating video stream from 4 traffic surveillance cameras to a central location at 3mbps over wifi link. From the central location, I am setting up a backbone link of 1.5 Km to the server room. So, for this backbone link I am planning to use bulletM2Hp with 24 dBi parabolic antenna.
I hope this should be fine? Please suggest

Pradeep, I'm interested to know more about your experiences (successes) with video using this hardware combination as I plan to do a similar thing. Would be greatful for any correspondence, thanks.

Also, for the speeds you are looking at, standard 802.11a Ubiquiti equipment would work, e.g. Bullet2HP.
At least these are mature....

Are you saying bullet2HP for 802.11a or you meant bullet5HP .. correct me if i am wrong.. i thot 802.11a refers to the 5.8ghz frequency?
