Gizmodo UK is better than Gizmodo USA I see.

Well gee golly, two Ghz of bandwidth is used? Imagine what could be accomplished with 100! Of course, that 4' dish is a tight fit in my pocket.

Well, when they deliver 10MBPS to my house I'll be impressed

It was that or the Buggles, which do you want?

I stream all my radio.  Tunein Radio is a good thing.  DNRTFA

I like to call it a live podcast.

Communication for the Resistance?

This technology would be great at bring high bandwidth to and through rugged terrain and mountainous regions via fixed ground stations, but I'm struggling to see how what they've tested will work in the mobile platforms.

To bring high bandwidth to flatter, rural areas, it still sounds more effective to lay fiber and pop in more conventional end-user wireless stations along its path.

That's kind of a silly headline, since every farkin' tablet and cell phone uses radio.  That's what they are:  the marriage of computers and radios.

No, that will be with high frequency radio, probably using low power, lower-HF Near Vertical Incidence Skywave techniques to minimize the danger of radio direction finding and to provide complete but low bandwidth coverage over a distance of up to 300 miles regardless of terrain.

If computers are used for transmission/reception, they'll be ones that have had the ability to connect to the Internet physically destroyed, so no reporting back to the NSA.  Also, as an added security measure, it would be wise to never place plaintext on them, so while you might use them for the ability to send digital data back and forth over radio using the sound card, they would be much harder to monitor remotely.

This means encrypting/decrypting data manually.  This is a really good security measure *IF* you chose a secure encryption algorithm.  For the really important stuff, probably OTP's.  The pads are most securely made by hand, but you can generate them on a computer using random data (like radio static) as an input, but you have to completely destroy the computer and printer afterwards, and their capability to access the internet or other computerized devices must be destroyed *BEFORE* you start generating the pads.

For the less important stuff, or as a back-up, then a manual method similar to the VIC cipher would work.

For tactical stuff, simple code words for stuff.  Tactical communications should be avoided whenever possible, however.   When necessary, they should use the lowest-power possible, and probably should be higher HF radio (like CB, below 30 MHz) instead of VHF/UHF or cell phones because DHS drones are designed to intercept and direction-find communications from 30 MHz to 3 GHz.

CBP's specifications say that signals interception and direction-finding technology must work from 30MHz to 3GHz in the radio spectrum. That sweeps in the GSM and CDMA frequencies used by mobile phones, which are in the 300MHz to 2.7GHz range, as well as many two-way radios.

The specifications say: "The system shall provide automatic and manual DF of multiple signals simultaneously. Automatic DF should be able to separate out individual communication links."

Of course, the real problem with any hypothetical resistance isn't communications technology, it's penetration by government agents.  Something like 25 to 45% of the Malheur Dildonians were government informants.

The FBI also had pretty significant penetration into other groups like the white supremacist ones, biker gangs, etc. While one could use runners to take messages (thereby completely sidestepping any chance of having radio comms intercepted), chances are at least some of those folks writing/carrying/receiving the messages are going to be passing them along to the government anyway.

Precisely.

From an operational standard, people like that should be executed quickly and if possible, their body left with a note saying they were an informer to discourage others.  At least, according to the 1939 British Partisan Leaders Handbook (see section 12).

But then, the same manual also recommends you bury your guns and ammunition because the first thing an oppressive government is going to do is take them away from the civilians.  (Appendix IV)

What if the reason we don't hear alien radio is because the protocol is so complicated that it's indistinguishable from background static?  Ignore all the other reasons this is improbable.  It'd make some good scifi handwavium.

Yeah, a spread spectrum protocol would do this. Anything on any kind of discrete frequency would be a noticeable spike over the background, even if it's indecipherable.
