If the zombies attack, I want a 2 meter portable and a 20 meter HF rig. From: Colin Stanners Sent: Sunday, February 21, 2016 8:56 AM To: [email protected] Subject: Re: [AFMUG] HAMSs and Internet
It's true that analog/slow-speed digital systems like the old ham stuff are getting obsolete for most communications including emergencies, but satellite-based links and phones, while reliable, are still super expensive (equipment / MRC), proprietary / difficult to source and repair locally, and slow/high latency. There are a few groups of hams who are creating high-speed "HSMM" IP networks. I'm a member of one located in Winnipeg - we take old/broken/cheap Ubiquiti/Mikrotik/etc gear and antennas (usually single pol) being discarded by local WISPs (and AFMUG members who donated gear, thank you!) and run them in the 2.3Ghz (Canada only?) and 5.9Ghz ham bands. These are for testing, ham VoIP and low-bandwidth uses, but with the nice tower locations we are building up (some of the best in the city) in an emergency we could install 5-10mbit low-latency IP communications within hours to multiple locations... that is with the current hardware in our garages, not needing $100K of satellite gear. One of our later plans is links through a few rural ham sites (you can go really far on 5.9ghz without interference) all the way to a different major city, or possibly province, with its own internet feed. So even if the batteries at our sites run out, sending out a few people with generators would still keep our VA4WAN system online - and therefore emergency sites - even if our city somehow lost all electrical power and fiber internet feeds.

But in reality it's the all-IP, digital, packet based communications infrastructure which cannot be touched by terrestrial disasters which will provide vital service in and out of a disaster area. For example your local county's fire department, which very well may have used some DHS grant money to put a 1.2 meter self aiming Ku-band VSAT on top of a command post vehicle. All you need is electricity (which you also need for ham gear) and you have connectivity anywhere in North America, no matter how messed up the disaster, unless the vehicle itself is destroyed. Or, for example, ham people who think their noisy radios will provide local communications, when you would be much better served by handing out folding 40W solar panels and Iridium satellite phones with standby-plan SIM cards in them. The Iridium network is completely impervious to terrestrial disasters (unlike mountaintop ham radio repeaters, etc), because it passes traffic satellite-to-satellite through space until it reaches the commercial gateway in Arizona. Unless somebody flies a 767 into the Iridium gateway, it will continue to function. There is also a DoD gateway in Hawaii which traffic can be routed through. A theoretical county-sized emergency operations department could keep a stockpile of Inmarsat iSatphone handhelds, which communicate with a set of geostationary satellites and will work reliably anywhere south of 65 degrees latitude. The satellites are impervious to your local disaster and the teleport locations through which Inmarsat traffic passes are unlikely to be in the same location as your disaster.

I belong to the club of "I don't want to pay for anything". I know, they supposedly have a public emergency benefit. I haven't ever seen them be anything more than a murderer in those situations but maybe we just have a bunch of HAM dorks around here.

A conference server would host multiple connects all at the same time, if they needed 500k per connection that would add up. I would not let them host a conference server on your wireless network, that stuff is better placed in big data centers. > > I am an amateur radio operator and have data and voice networks I maintain for the clubs locally. Honestly 1 to 3 meg is more than enough for what they will need. Anything more than that and they will likely be doing things that they should be paying for on your network. They may be trying to do some live video stuff but you don't need to shoulder that burden, they can do live TV broadcasts on spectrum they have available, not as easy to do as IP cams and Ethernet but they can do it. > > If you have the tower space you might consider offering them places to put their own links if all they need is bandwidth between sites. There are amateur radio spectrum allocations in the 3.3 GHz band as well as 5.9 GHz, and I am pretty sure they can load international firmware and run their own links on MicroTik or Ubiquiti radios. This would keep the traffic off your network and possibly discourage them from putting up links legally licensed in the bands you are using for your business. Technically they have licensed rights and could knock you off the air. Best not to start that war, they can operate in the 900, 2.4 and 5 GHz bands legally at much higher power. If you can get them off on to the spectrum that does not overlap the unlicensed bands everyone wins. They also have their own IPv4 space available (ampr.org). > > Feel free to hit me up off list and/or have them contact me if you need to.

Now one of their members has asked for Internet service at one of the sites for HAM use.
