Sonnet Devices BETA


#21

Sorry for not doing an update! I got busy. I should be able to do an update on Saturday as I’m not home for the next couple of days.

We did some ping tests, I have the results on my computer so I should be able to post them up, or the summary.

If I get enough time I will do some ping tests on other frequencies and power settings.

Sonnet Update!
Well, preliminary update, I haven’t done any additional testing (Different frequencies/power) since doing these tests, I might be able to get to that later today. This was conducted at 2.0W on 915MHz

My plan is to go down to the airstrip, where I have a bit over a mile of full clear and open ground where I can do the testing, using two laptops to ping each other. (I have clear ground where I did these tests, but the strip is more convenient/isolated from any possible interference)

The problem unit (let’s call it #3) is still completely unresponsive so it has been put in the good ideas pile for the time being. I wanted to be able to test if it did hop the signal.

The tests;
Using SSH to log into the devices and operate directly I was pinging the devices to each other, I decided to set it up as the base unit constantly pinging the distance unit to see if I would get losses on only one unit, and to ensure the connection was maintained.
Base = #1
Distance = #2
What I had found is that if a unit went out of range, or lost connection with the other it would reassign the IP and they took a while to reconnect to the network, but they would reconnect.
In starting/establishing this test I found that if the Sonnet is connected to WiFi, and it loses said connection it will reset its own WiFi, but not the Mesh.

Test 1) Stationary connection.
With #2 set up at 1m above the ground orientated as Brian suggested, at 180m I was able to ping the unit, with 85% losses. I tried with it laying flat on the table, but it wasn’t showing up.

Test 2) Locating the distance at which losses would be 50%
With #1 and #2 running a ping sequence I started moving the devices further apart, starting at 30cm and increasing by 1m every 2 seconds, I had my laptop (Surface) with me as I walked so I could watch the readout.
As I started to approach 120m I started to get some greater losses, and by eye figured it was close to 50%
This sequence resulted in 21% packet loss as I was narrowing it down to 115m


Test 3) 115m new sequence, some movement (+/- 5m)
I wanted to ensure I was at the point where I would have 50% losses, so I ran a new sequence from this distance, I moved forward and backward at the same rate as test 1 to see what drop I would have, the sensitivity of the radio and to ensure the connection was maintained.

During this whole process Unit #1 (the base) didn’t lose the connection and it had a 34% loss the entire time.

At some point, I might see if I can fit one into a pringles container and can-tenna it with the internal antenna.

It looks like the team at Sonnet are quite busy at the moment!

This is all very good information. With clear line of sight at 2Watts you should be getting much better range. I wonder if there is a hardware issue with a certain batch of units that is causing such a high packet drop rate or something very specific about your environment that is causing the issues.

Sonnet seems to be pretty tight lipped on any of their beta testing results but it would be interesting to see what others are getting. They mentioned getting about one mile range so your results seem peculiar and quite unexpected. Pinging the nodes should be the easiest task and yet there still seems to be issues. My completely wild guess would be there is something wrong with the amplifier that is not allowing the full 2watts to get transmitted; a fried transistor perhaps.

Thank you for the information. It is odd that the range is so short. I have an Yaesu Vx-3r which is good for 1.5 watts at 144 and 1 watt at 440 and I can hit repeaters a few miles away. But those repeaters are on the top of buildings.


#25

Do you have any power meters like the diamond sx1100? That one should cover some of the frequencies and it has a low 5 watt range. With that and a dummy load you could see how much power they are putting out.

I have all of that equipment so once I get my units I can test the power.

Hi wvs, Brian, and everyone else!

Sorry I’ve been out a lot this last week, and haven’t done any more testing.
My thoughts would be along the lines of a fried transistor, it feels a little like that. But will see what the team have to say when I get a break in the work side of things (Summer, its great for thirsty cattle, 46C/114F degrees today)

Having seen some of the performance that I can get out of a baofeng UV5R (in 477) being close to 40km LOS I’d be hoping for something near half that out of a smaller unit.

I unfortunately don’t have any radio testing equipment, I think I might need to pop onto eBay and acquire some.

Hello

Any new updates on your testing?


#28

At the moment I’m swamped with work so I haven’t been able to do the latest test!

One of the team ran me through flashing the mesh firmware on my two working units a bit over a week ago.
So at this stage it’s me holding things up! I might be able to get a few moments where I can test in the next few days.
