Right now you can get away with a lot of "oversubscription" in MDU situations when you have 1-2Gbps to the building (typical millimeter-wave radio speeds). I wouldn't be surprised if they have buildings fed with 1x1Gbps going

So much this and worse. In my state the ARES/RACES people got together and made a "statewide emergency network" of repeaters using local IP for interconnect. Our rural WISP arm provides the IP for several of their repeaters (

Not really... On the low end (small ISPs with zero or a handful of downstream ASes), people aren't aware or are too lazy to implement egress ACLs. Complicating this: A surprising number of small ISPs and telcos don't actually staf

I haven't encountered any keybinding conflicts or unusual behavior with the standard SSH app (nassh), when using vim and tmux or anything else.

Exactly. We usually aim for a 10-month ROI and that's using higher-end Cambium radios (way better for ops at scale than something like Ubiquiti), Juniper network gear, batteries on everything, and proper telco circuits. We also have a

Roughly speaking Brett Glass is to WISPs as Richard Stallman is to the modern open source ecosystem. Maybe did some important things back in the day but for the past 10 years the situation has largely shifted from idealism to pragmatism. Ye

Latency & self-sufficiency. The initial use seems to be as tankers for crewed aircraft. Local control means no satellite round trip delay and perhaps the ability to conduct refueling operations if satellites are broken.

54VDC and 48VDC are roughly the same thing in telco land. E.g. I hooked up a Juniper MX960 last week with "-48 VDC Nominal" power supplies. The operating voltage range is -40 to -72VDC. A "48V" rectifier will output 54VD

On a network like that, wouldn't DDNS solve the problem? I mean DDNS where the DHCP server tells the DNS server which IP has what hostname, not e.g. dyndns.

Oh, I forgot to mention... there is a mechanism for providers to challenge coverage to get CAF funding because all sorts of providers overestimate coverage--there was a Ars article a few months ago about a Cable provider telling someone the

A WISP (or any other provider) that provides 25Mbps download+some nominal upload to a area (and reports that on their bi-annual FCC form 477) would cause the area to be marked as "served" and thus ineligible for CAF funding. IIRC

I don't think he's saying no one needs gigabit fiber period , rather not everyone needs gig right now , which is demonstrably true. Even 4k is doable without gig using HEVC (50Mbps is typical ref: Wikipedia) and when uncompresse

There is a huge difference in the amount of bandwidth that can be moved via satellite compared to undersea fiberoptic cable (not to mention differences in latency). If all cables were cut and we went back to satellite we'd essentially

There's very little red tape involved in starting as ISP in the US. The red tape starts up to 6 months in when you hit the bi-yearly FCC Form 477 filing, though I'd say the majority of (w)ISPs are flying under the radar by simpl

Assuming it's PMP100 (PTP100 is essentially the same gear, except a pair of radios dedicated to each other instead of one AP and up to 254 clients). PMP100 is capable of 14Mbps aggregate, often set to ~10Mbps download, 4 Mbps upload. I
