Description

This is my experience with unboxing and setting up a pair of NanoStation 5AC's.  The setup was super easy, however I was unable to obtain full speed out of the device (max sustained throughput ended up being around 170Mbps).  Any suggestions for further testing are appreciated!

 

I show this device in UNMS as well as go over the onboard GUI interface and mobile device setup.

recommend upgrading to 8.5.4 and dropping Tx Power to the lowest (-4) and setting a password as I've heard they run faster due to the chip being designed for encryption thus having to do less work than without a password (or something!)

Nice video! We are in touch on email to sort any of the problems you had here.

First things first, it's not FREZ-KNELL, it's FRAY-Nel...

 

 

So the problem here is clearly your ipef3 test.  You are in TCP, not UDP, you are only using one thread.  And then something maybe on the PCs (like cpu limit) or switches.  TCP has some overhead that simply isn't accounted for in throughput in iperf.  iperf can be CPU demanding, check that you arent maxing out a CPU core.  Regardless, run it with -u and -P 10 flags.

 

Another issue is that your chains aren't balanced.  That's why the signal levels are in red.  When you bring them inside, you are WAY overpowering them.  You need to get the alignment a bit better.

 

What leads me to this is your speedtest on the devices.  You have it on DUPLEX, which does a TX and an RX simultaneously.  When you add these together you get 367.58Mbps, which is getting pretty close to target.  Now, when you do a full duplex test you are using the link at it's 'worst', meaning you are really leaning on the guard intervals as you switch back and forth in tx/rx.  If you do a one-way test you are getting about the best you can in radio time.

 

I bet if you run the speedtest again in a single direction you will hit right about 400Mbps.

 

Also, you need to try to get your signal between -45 and -55 and balanced so the H and V are within 1-2dB.

Great video!

 

As an update, I tried the same thing with two Nanostation AC Locos I've just got for a CCTV job. 

 

Test link is 15m, with both Nanostations set to -4dBm, signal -43dBm.

 

With iPerf3 I got the following...

 

Benchmark - PC-Server hardwired (2 switches) - 920 Mbits/sec

Laptop-Server wireless (UAP-AC-Pro) - 214 Mbits/sec

Laptop-Server (Nanostation link - firmware as delivered / no encryption) 128 Mbits/sec

Laptop-Server (Nanostation link - latest firmware / no encryption) 302 Mbits/sec

 

Laptop-Server (Nanostation link - latest firmware / no encryption / 10 streams) 376 Mbits/sec

Laptop-Server (Nanostation link - latest firmware / WPA2 encryption / 10 streams) 346 Mbits/sec

 

(When I was at college, we were taught FREZZ-NELL!)

 

ETA as an extra test, I put both up to full TX power (signal -30dBm) and the speed was still 342 Mbits/sec with encryption and 10 streams...
