What is Maximum Throughput for ePMP1000 - 5 Ghz Radios in TDD Mode?

Can someone at Camium tell us what the maximum throughput (download and upload speeds) one can achieve using a 5 Ghz ePMP AP and one ePMP1000 SM set up for standard TDD mode, 40 MB channel and 50/50 up/down. 

This path is a line of sight shot of..3 miles (with no obstructions in between - just air.  There is absolutely no interference on the selected frequency.  

Just to clarify, this link is installed way out in the country, 40 miles from no-where, including the closest gopher. 

Signal level at the SM is -50 Dbm.  Signal to noise ratio is 55 DB. MCS downlink and uplink are both solid at 15.. 

What can one expect the maximum download and upload speeds to be (actual throughput)?

I am insterested in actual

40MHz = 200mbps total/aggregate ... using TDD 50/50 would deliver 100mbps up and down.

If you install 4.5, and enable short GI... you should be able to squeeze another 10% more out.

If you're sending a high number of small packets/high PPS, then your throughput will be lower due to the CPU in the e1k's being slower then e2k or e3k.

We've tested these using Mikrotik routers on each side.

Thanks for your reply, Eric.

We are seeing about 45 MB Download and Upload on a 40 MHZ Channel using TDD.

For everyones information, when we changed the link to PTP using the same equipment, we are seeing close to 100 MB Down and 100 MB Up.

ePTP or TDD-PTP?
