We don't support roaming yet, so phones from other carriers won't work on our networks. The networks are fully independent, with their own phone numbers and connectivity to the glo…

Basically this. Spectrum regulations (both de facto and de jure) vary dramatically between jurisdictions. It's definitely a challenge, but not as big of a deal as one might expect,…

Our current model retails for $6,000. It's an exciting time to be working in this space -- five years ago, setting up a single tower in a rural location could cost upwards of $100,…

Cofounder here. All service is prepaid, and we have a credit transfer system built-in. The network operator can load up credits onto someone's account directly through our manageme…

It seems like there's been another surge of interest of late in mesh networks. Last time this happened, I wrote up a piece explaining why mesh networks are really a poor solution f…

I have this sitting on my desk at the moment (just OpenBTS + rPi + a SDR). Nothing too crazy about it. I like this because they are using the rPi itself as a radio -- that's a pret…

To be fair, they're not explicitly charging twice as much for consistent reads. You get consistent reads until you exceed your provisioned read amount, which unfortunately is measu…

I'm less worried about this actually -- I think the biggest problem is your own nodes interfering with themselves ("internal interference") rather than with an attacker. Agreed thi…

Comment #3281919
Even an electronically steerable antenna would help, but then you start running up the cost of equipment. Interference is still an issue since one must always be listening from all…

Comment #3281915
I generally agree, but I tried to shed some light on the fundamental physics/math behind why building such a network is impractical. In any case, it might one day be possible, but …

Yeah, that's the tricky part. It took a couple revisions in front of users to figure out the right way to do bootstrapping.

We need to get a dozen or so simultaneous users for it to work nicely. Please be patient! I'm seeing several users calling in right now. Edit: we've made some changes to greatly in…

Excellent point -- no simple solutions. It's why this is a hard problem.

Comment #2286602
Once again, I don't dispute that; we're in full agreement. My key point is that the effects of liberalism that lead to growth in Hong Kong did not lead directly to growth in rural …

Comment #2286203
I never meant to say communism was responsible for the country's economic growth. Clearly, liberalisation caused that, as your graphs imply. However, the growth was concentrated on…

Of course, that is clear. However, declaring a Charter City won't magically erase corruption and other structural causes of poverty, and bringing in a foreign party to impose gover…

Most folks I know living on reservations would debate that. Just saying, it's a strong claim to make.

Comment #2285446
It's arguable whether such a thing is possible. Cooperation, where all stakeholders have say in the endeavor, is probably close to ideal. But that's not colonialism. Once you start…

Perhaps more accurately, it doesn't work well for those involved who don't have power. Puppet governments seem to do quite well for themselves, as do the colonizers.

I'm not going to fault this piece for being hand-wavy and poorly justified: it is that, but then again, it's a piece of popular journalism which is allowed to be. So, I'll criticiz…

Right, but the idea behind direction finding is that you can triangulate the position of the transmitter. If you just have a bearing you have to search over a large area -- these l…
