I just tested a cable tester from Ideal that qualifies GigE circuits. Nice thing is, it will do a data test without cable continuity. (It also does the actual cable continuity tests too).
I wonder what it would show on a less than 1Gbps radio. $1325 From: Harold Bledsoe Sent: Monday, April 04, 2016 1:32 PM To: af@afmug.com Subject: Re: [AFMUG] IniteNet 60 GHz radio iperf tests? Sorry to be late to the party. ;-) I have a few comments on iperf though. Iperf2 is not very reliable at high speeds. For high speeds, iperf3 tends to do a little better assuming you have enough computer to push the required speeds. However iperf3 cannot yet do bi-di tests. For affordable testing, we've found Mikrotik's traffic generator to be pretty good. It's a little complicated to setup the first time but then it is better. Beware using btest - it uses a single core and can't keep up especially if you try random data. Then there's RFC testers like Exfo, Smartbits, etc. We use Smartbits.

We’ve heard so many promises in the past and very often the truth does not meet marketing. So there is nothing aggressive if someone wants to see iperf testing. Seeing is believing.

I also apologized for this being a personality defect in myself. The Cut & Paste was not for your benefit, but for others who lurk in the forums. There is nothing wrong with running an iperf test.. but you specifically asked for the test to be run in a very particular way, from very particular pieces of equipment..... My apologies if I am over reacting.... WISP's have many many great attributes, however there is one attribute which would be nice to change for the better....

For somebody who doesn't own a piece of the company and doesn't work there, you're extremely defensive. I don't need a copied and pasted explanation of what FDD and TDD are. How in any way whatsoever is it inappropriate to run iperf tests on a newly released PTP bridge radio?

The transmit direction and receive direction frequencies are separated by a defined frequency offset. In the microwave realm, the primary advantages of this approach are: ----------------- NO THEY ARE NOT FDD. ------------ Time-division duplexing (TDD) is a method for emulating full-duplex communication over a half-duplex communication link. The transmitter and receiver both use the same frequency but transmit and receive traffic is switched in time. The primary advantages of this approach as it applies to microwave communication are: ------------------ YES They are TDD. ( The notation of 1gig aggregate should have give this away ! ) Like all new products, they are making improvements with firmware updates. The published specs are 'conservative'. These are the first radios of their kind in the market place... I think you will need to modify your thinking about them, cause you keep comparing them to the other existing (much more expensive) radios in the market place. Anything else you would like to know ? Feel free to ask...... BTW, FWIW, I don't work for Ignite, nor do I own a piece of the company (would love to buy stock in them if I could). I am on the beta testers of the product... There is something about the tone of your question that is rubbing me the wrong way, my apologies if I am over reacting...... I normally expect the proper professional decorum to be.. ask the question directly, and only if that is not answered or if the answer is not straight forward then it is ok to imply some intentional obfuscation..... not the other way around ! :) Faisal Imtiaz Snappy Internet & Telecom 7266 SW 48 Street Miami, FL 33155 Tel: 305 663 5518 x 232 Help-desk: (305)663-5518 Option 2 or Email: supp...@snappytelecom.net -------------------------------------------------------------------------- From: "Eric Kuhnke" <eric.kuh...@gmail.com> To: af@afmug.com Sent: Sunday, April 3, 2016 11:14:08 PM Subject: Re: [AFMUG] IniteNet 60 GHz radio iperf tests? I'm not trying to prove or disprove anything, just to compare them with existing line rate 60 GHz FDD solutions. The datasheet says 1Gbps aggregate throughput but nowhere does it say specifically if they're FDD or TDD in the 60 GHz band: http://www.ignitenet.com/wp-content/uploads/2016/01/IgniteNet_MetroLinq.pdf On Sun, Apr 3, 2016 at 8:01 PM, Faisal Imtiaz <fai...@snappytelecom.net> wrote: What exactly are you looking to prove of dis-prove with such a test ?

Are you asking the question 'How much data I can push thru with these radios ?'..... the question has been answered multiple times... the radios are (as per specs, 1gig half duplex, thus giving you 500meg x 500meg performance.) The Radio side is using 2ghz wide channel, and the latest firmware is showing 700meg x 700meg performance.... What is the problem with this ? if you think Ignite is lying about the specs, buy a pair, do the testing you like, with pink, blue, or purple laptop of your choice and if you don't like them, send them back !... or someone will be happy to buy them from you ... they are in short supply as it is .... :) Regards.
