Meshoween test results

We've wrapped up the Meshoween network abuse test  :-). 
If you participated and have any specific observations, please pass them along to me (orv.beach@gmail.com) and they'll be rolled them into the report on the test. 

tl;dr - it went pretty well - a few surprises.

Network Test Saturday, October 30th

As an AREDN network grows in size and/or complexity, it will eventually encounter a packet storm that would pretty much cripple its traffic-carrying capabilities until the storm fades out, which could be hours.  (The writers of the OLSR mobile routing protocol probably never envisioned it having to handle networks of the size amateurs are creating.)  This is significantly limiting the growth and performance of our networks.

Recently released nightly build 571 provides a substantial amount of resistance to these storms.  As a test of the network's robustness (or not) Saturday October 30th at 9 a.m. local we'll attempt to link as many AREDN networks together as possible.  

We did a 'test test' earlier in the week on the West Coast when the Southern California and Bay area networks were linked.  Node counts got up to a bit over 800 and few reports were received, so we're ready for Saturday!

Test preparation

Prior to Saturday's test, it's recommended that in order to protect your node(s) that you upgrade them to the latest nightly build (599 as of this writing).  This is especially important on nodes that pass data through (as opposed to being an end-point on a network).  

Also prior to Saturday, establish some baseline performance measurements on your network.  Suggestions are:

  • Quality of VOIP phone calls
  • iperf throughput...

AREDN in February 2019 QST

AREDN Mesh Tunnel via Satellite at Baker 2 Vegas 2018 by Oliver Dully, K6OLI appears in the February 2019 edition of QST. This article is a thorough discussion of setting up the communications system at this large annual event..

Oliver reports that the combination of AREDN mesh and Cell On Wheels (COW) trailers set a positive precedent for the future of disaster communications and the Amateur Radio Emergency Data Network.

AREDN Presentations at SCALE 17X March 10, 2019

There will be two AREDN presentations at the 17th Annual Southern California Linux Expo – SCALE 17X – to be held on March 7-10, 2019 at the Pasadena Convention Center in Pasadena, California, near Los Angeles.

Both presentations will be on Sunday afternoon, March 10 in room 212.

The first talk by Orv Beach, W6BI is titled “The Ham Radio Internet - a Progress Report”. It will start at 15:00 in Room 212.

Orv reports that IP Networking is one of the fastest growing modes in amateur radio.  The ham radio internet (lower-case eye) continues to grow in both capabilities and span. Driven by improvements in custom open source software for wireless access points by AREDN (arednmesh.org) and with their support of more equipment from more vendors, it now covers from Santa Barbara to the Mexican border and east at least to the Inland Empire.  At any given time, there are more than 300 nodes up and running.

He will detail that growth with emphasis on Southern California, with metrics, maps and graphs.  He'll also cover some of the more significant network events, including...

Yuma Hamfest 2019


Andre, K6AH, will present an update on the AREDN team's open source software development progress and report on useful tools and techniques to ensure a successful mesh network implementation.  His talk "AREDN Project: New developments in software and successful implementations around the Southwestern Division " will be given on Saturday, February 16, 2019 at 11:40 am. Andre will describe new Emcom applications which make the mesh even more usable.

The Yuma Hamfest and ARRL Southwestern Division Convention will be held on Friday and Saturday, February 15 & 16, 2019 at the Yuma County Fairgrounds, 2520 E. 32nd Street, Yuma, AZ 85365. For more information, see the Yuma Hamfest website. For tickets and vendor registrations, see their online registration form


Auxcomm Symposium in Southern New Jersey


On Saturday, February 16, 2019 the Medical Coordination Center (MCC) at Cooper University Hospital in Camden, NJ will be hosting an ARES/RACES/AUXCOMM Symposium for hams in the Southern New Jersey and the Eastern Pennsylvania areas. The MCC is beginning to use AREDN and would like to see the technology adopted more fully in their area. The event runs from 9:00 am to 3:00 pm. Presentations in the morning will be given by:

  • Bob Bruninga WB4APR - APRS
  • Joe Everhart N2CX - NVIS HF Field Antennas
  • Cory Sickles WA3UVV - Yaesu System Fusion
  • Randy Smith WU2S - AREDN high-speed multimedia mesh networking

The afternoon will consist of breakout sessions and demonstrations.

AREDN at Frostfest 2019

AREDN mesh networkers will be at the Frostfest 2019 in Richmond, VA on Saturday, February 2, 2019. The location is the Richmond Raceway Complex, 600 East Laburnum Avenue, Richmond, VA 23222-2253. This event is the ARRL Roanoke Division Convention, so there will be many League officials on site.

A group led by Damon Schaefer K9CQB will be on hand to demonstrate equipment and answer your questions. Just look for the large AREDN banner at their table. His team plans to populate the booth with several masts bristling with equipment and 2 large monitors, one running an AREDN slideshow and one with a local mesh network for live demonstrations. 

Stop by and say hello!


Standardized NanoStation XM Ethernet port configuration


The NanoStation XM devices now have fully functional ports - both main and secondary.   This capability will be in Dec 3, 2018 nightly build.   The behavior is now same as NanoStation XW devices.   POE Passthough is also functional.   

This new capability means the following usage is significantly simplified to setup.   At local community events when setting up ipCams around a parade route or event area, there can be a station with 2 nodes -- incoming link on one channel/band and outgoing link on another channel/band.  This means many HD video quality signals can go through the station as this relay station does not share the same frequency.

Before:   

2 mesh nodes, 1 ipCam, 1 5-port switch, 4 way power split to all devices, junction box.   Lots of labor and points of failure to build and configure the enclosure and cabling.

After:

2 mesh nodes, 1 ipCam, daisy chain the cat5 cables though these devices, no enclosure.   


Issues to consider when deploying:


1) I've seen a NSM2 XM device...
