Started this web page when I got a WISP (Wiki) account.
Dial-upWhen I first moved to Ukiah my internet connection was dial up. I went to their office and picked up the Netscape browser in a retail cardboard box and installed it. That got me email and the ability to browse. In a year or two Netscape added the "Composer" which was a WYSIWYG (Wiki) web page editor that allowed me to make web pages and store them in the 25 Mb of space I was allocated as part of my subscription. This meant that only very small thumbnail photo could be posted.
2-Way SatelliteNext, in 2001, came 2-way satellite (see: Starband). The biggest problem was a rolling 7-day data cap at 1 GB. I learned to work around the Solar outages (when the Sun moved to the same location as the satellite). But near the end the time for an eBay web page to load was very long (a coffee break made sense and you needed to think if you wanted to go to a web page because of the long delay).
DSLIn 2008 and 2009 I signed up for AT&T DSL but when the hardware arrived by mail and installed it did not work and tech support gave up and I sent it back in 2008 and again in 2009. I offered a service technician at the crossover box a lot of money if he could get me internet. He refused but told me AT&T must make it work. So the third time was the charm. I'm at the maximum line distance from the DSLAM for DSL so have poor service and buffering is handy for bathroom breaks.
2019 October 7: SeaKay installed a dish on my next door neighbor's house and later installed a small dish on my house. Their Tier 1 (slowest) service is 3 M bits per second up (6X the DSL speed) and 6 M bits per second down (3X the DSL speed). The jitter and latency are about the same as DSL. This, like each of the above changes is a huge improvement.
The under 8" diameter dish houses all the electronics. These come in 2.4 GHz and 5.8 Ghz versions, where the 2.4 GHz version is used here because the path is through trees. The "2" in 2AC signifies the 2 Ghz band rather than the 5 GHz band. the "AC" is the newest generation that makes use of TDMA (Wiki) as opposed to the WiFi technique of FDMA (Wiki). Note cell phones started out using FDMA but soon upgraded to TDMA since it has many advantages that also apply to this application.
The LAN (Wiki) cable has 4 pairs of wire. 2 pairs are used for transmit data and normally the remaining 2 pair are not used. But in a Power over Ethernet Wiki: PoE) system the normally unused pairs are used to signal that there is PoE and to supply a nominal 48 VDC to the load device, in this case the antenna assembly.
MikroTik hAP ac lite Router & WiFi
The AT&T and D-Link DSL modems provides a few LAN ports as well as WiFi for my house. This function was replaced by the MikroTik hAP ac lite. It also supports PoE out on Port-5 to power the Ubiquity dish. The DC input can come from a wall wart rated at 10 to 28 VDC at up to 0.5 Amps or through PoE input on Port-1. The wall wart should be rated at 24 VDC 1.2 Amps according to their brochure (I have not yet unplugged it to see). It also supports both 2.4 and 5.8 Ghz WiFi.
The hAP ac lite Access Point just passes the DC power it gets in to it's output. This means it would be best to supply it with 24 VDC, but nothing higher. Also the NBE-2AC-13 has an upper limit on input voltage of 25 VDC. This suggests that the most efficient back-up system would supply 24 VDC from a UPS. Similar to the Belkin, or maybe 2 of the Belkin units connected in parallel (though that has a kluge aspect). So far I have not found any ready made UPS units with just 24 VDC out.
Yesterday I got a robo call from pg&e asking me to go to a web page and enter a very long security key which I could not remember, but tried to write down. Today I received that same call, this time with better audio quality, but the at the 6th character they key was different. That does not matter because as of 1 pm 2019 October 8 the whole pg&e web site is down. What they have done amounts to a DDoS attack (Wiki) on themselves by asking half of California to go to their web page. This seems stupid since the outgoing message is going to people where they already know the address, i.e. instead of asking people to go to pge.com and look up a secret key, they could just send the information they would find out in the message.
This brings up the question: What happens to my internet service when it's fed from a wireless point-to-point network? There's a relay on my neighbor's roof that probably has a very short term battery backup (2 hours). I don't know how many other relays are in series (none). SeaKay says some of their towers have battery and or generator backup (my path does). They ass-u-me that the fiber optic service providers that feed them have batteries and generators, but . . . no one knows what will happen if half of California is shut down at the same time.
The DSLAM that feeds my DSL account has maybe a day of backup power so is slightly better than the 2 hours I may get with this setup.
PS I'm keeping the DSL account until I have had some experience with this WISP (Wiki) account.
It turns out that the PG&E shutdown the night of 8 October drained the small battery on my neighbors system and so I don't have that system.
BUT . . . DSL is provisioned on top of a plain copper pair telephone circuit and that phone circuit falls under FCC Title II. That means it needs to work during an AC power failure. My DSL failed around 8am, but by around 8:30am was back up based on at&t adding a generator.

The large dish points to the SeaKay tower. The smaller dish in back looks like the same one as on my roof and points to it. Note the bubble level at top center and the blue LEDs at about10 O'clock.f just like Fig 2 at the left.
There is no backup in this setup so it fails with AC power shutdown.
