Currently my sources of internet are:

1. Wireless Internet Service Provider (WISP) using equipment by Ubiquity.  It's fast but stops the second there's an AC power faiulre, something that's getting more common each year because of wildfires and PG&E planned shutdowns when the fire danger is high and it gets windy as well as the power line upgrades being done to support the grow lights (Wiki) associated with indoor pot grow operations.  So, Fast and Unreliable.
2. AT&T ADSL (Wiki) that is provisioned on top of a copper pair phone line.  Because of the copper pair FCC Title II (Wiki) requires that the phone work in emergencies, which working when there's a power failure.  To that end the DSLAM (Wiki, Telephone Poles Fig 11) has an internal lead acid Gell Cell battery good for a few hours AND a seperate pedistall for connecting a backup generator.  This means the DSL works all the time (as so does the associated phone line).  So Slow and reliable.

In the past I've used StarBand satellite service (Wiki: Starband, VSat) which is based on geosynchronous satellites.  The ping time or round trip latency (Wiki) was many hundreds of milliseconds.  That means VOIP will not work.  It also means the page load time for eBay is very long since every icon seems to require a ping to load.  But when there was an AC mains failure that lasted a day to two because someone a hundred miles south of us cut a fiber optic cable and shut down all the local telecphone AND internet service, the satellite based service kept working.  Although I could not phone anyonw, I could email. 

This Starlink (Wiki) low orbit satellite service will also be independent of the local AC power mains and has the advantage that it should support VOIP telephone service.  If it will work on a 24/7 basis then it offers the best of reliability and speed.  But I'm very concerned because I live in a forest.


Getting Started

Within the past week Starlink announced the new square dish system, but the one I received today 13 Nov 2021 is the round dish version.

Even though the App says:"Your starlink WiFi router needs to be updated to use this feature. Please reboot your WiFi router, it may take up to 2 hours to update." Im able to surf on my cell phone (the WiFi is connected to the Starlink router).  CalSpeed:

Moving Antenna to House

The Ground Pole Mount for my round dish arrived yesterday and toady (2022 May 14) moved the dish from the factory tripod to the pole.  But instead of mounting the pole in the ground It was put at the top of a chimney using lag screws.



It's my understanding that Mark Krebs, inventor of the satellite mesh network, worked for Google then moved to SpaceX.  So the Google patent applies to the Starlink system.  As of 16 Nov 2021 all 1584 of the Phase I satellites are in orbit (Wiki).  But this is a small fraction of the total number planned.

Dish & attached 100' Cable

The Dish is shipped in the Stowed position (Fig 4).  When powered it automatically levels itself (Fig 5).

The dish is a phased array (Wiki) antenna that can steer the beam electronically.  In addition there is a mechanical Pan/Tilt mechanism to physically point the antenna. (see: DE102021100212 patents below).

Router (Wiki)

Is there a way to change router settings?  For example change the WiFi channel numbers so they are seperated from my AT&T DSL and WISP WiFi signals.

Auxiliary Connector Speed

So far the speeds I'm getting from the Aux connector on my desktop computer have been under 40 mbps while on my cell phone have been over 100 mbps.

Comparison Test to see if Aux connector has a different speed than the WiFi.  All the tests prior to Christmas, while suspect, are confirmed by how I experience my email first thing in the morning.  The WISP (12 down) takes some time to load the email and when the speeds are in the 10 to 20 area it looks the same.  When it's much higher the email loads in the blink of an eye, a very noticeable difference.

I don't have enough experience with the Weather feature of to know if this explains the differences.  We have had more rain in the past few days than in what's common for this time of year in the past couple of decades.

Dual PoE (Wiki) Power Supply

This power supply has two LAN ports, each of which has a PoE output. 
The Gray colored one powers the Dish and is rated: 56V 1.6 Amps.
The White colored one powers the Router and is rated: 56V 0.3 Amps.
The two ports share data lines so that the data to/from the dish (gray) shows up on the port going to the router (white).  So if the router is unplugged that port can be used as a general LAN port.
This means all the internet functionality is in the dish assembly.  That's so say there's no electronics inside your house needed other than the PoE power supply.
Also that means a switch capable of 1.6 Amps at "56 Volts" could replace all the indoor equipment.
I've found power bricks rated: 48V & 240W (5A); 52V & 140W (2.7A);
The Ubiquity WISP system uses PoE in a similar way except they use a 24V supply.  All the internet functionality is in the outdoor dish.

Ground Equipment

The satellites communicate with Gateways (Wiki) on the ground.  I've seen photos that show what look like five foot diameter spheres with a skirt at the bottom making them look like a giant mushroom.  I expect they contain a phased array antenna that can track one? satellites.  Different gateway locations have different numbers of these collocated antennas.  Maybe up to a dozen at one location but more likely a handful.  Maybe the number of antennas corresponds to the number of satellites that can be tracked at the same time from that gateway.  Ketchikan, AK can be seen tracking up to 7 satellites at the same time, while Charleston, OR can track up to 4 satellites.
Gateways near me are in:
Redmond, WA
Colburn, ID
Prosser, WA
Kalama, WA
Charleston, OR
Tionesa, CA
Robbins, CA
Arbuckle, CA
It's not clear how the gateways connect with the POPs.  Hopefully by fiber optic cable, by maybe point-to-point microwave link?

The Gateways communicate with Points of Presence (Wiki: POP) which are located at major fiber hubs.
Seattle, WA [triangle 8]: SEA1, SEA2, SEA3, SEA4, SEA5, SEA6, LAX, Reserved
San Jose, CA [triangle 2]: SJC3, SJC4 [Home POP]

Backup Power

I have UPS power supplies for my computer equipment and a generator to power my house during the now common multi-day power outages. 

In the past when I had a VSAT terminal working from a geosynchronous satellite when our county lost all phone and internet service when a fiber optic cable was cut by a backhoe, the VSAT continued to work and I could email.  That system had one ground station in the U.S. located in Georgia, far from me.  Geosynchronous satellites do not support VOIP phone service because of the high latency.

So I'm wondering if the Starlink ground equipment has long term backup power?  Note batteries probably will not be enough since the power outages tend to last a few days.  AT&T brings in a small gasoline generator to keep my DSL working over these long AC outages since there local battery back can only keep the DSLAM box up for some hours.

Starting in 2021 California has a law requiring cell towers to work for at least three days without AC mains power.  This was a lesson learned after the 2017 fires shut down many cell towers and so a very large number of phones.

So far there is not a law about keeping the internet going in emergencies and many people with VOIP phones have found they do not work when the internet service they are based on quits working because internet is not under FCC Title II.  That's so say the federal government has not officially said that internet is a vital utility and must work in emergencies, like they did for the land line phone system.

Here's an answer to my question on reddit/Starlink. Ground Station Backup Power?

The idea of inter-satellite links will be a solution once there are enough of them working.  As it is now there are only a small number and they are being dedicated to improving polar coverage.  But in the future they would allow the signal to jump over an area where the ground equipment was non functional.

Note that this can happen when the fiber optic cable that is hung from wooden power poles falls down and breaks because the poles catch fire or are hit by a car.

For my other internet services there's a URL that displays the device as a web page.  For example for the AT&T DSL model it's:

Ubiquity USW-Flex-Mini. - Quick Start -

                      USW-Flex-Mini Switch 5-ports
Includes USB-C power supply.
Input: 120/240VAC 50/60 Hz
Output: 5V @<= 1 Amp

Is supposed to also run on PoE: 44 - 57 VDC, <0.05 A (for switch)

DOES NOT WORK without programming, i.e. a managed switch.
I connected the switch to the AUX port using the PoE Input and the power LED on the switch did not light.  Unplugging the white LAN cable from the router and plugging it into the switch does not cause the LED to light.  If a new LAN cable is then connected from the switch to the router the router does not turn on.  Tried other LAN cables and this does not seem to be a cable problem.  This is a fully managed switch and maybe needs to be programmed to use the PoE Input port, so looking for an unmanaged switch, like the D-Link DGS-108 (on order).

Unmanaged switch

To avoid the hassle of installing the configuration software, which controls all the Ubiquity LAN software and so I expect to be HUGE, I just ordered an unmanaged switch that's going to be plug-and-play.

dual-WAN routing

This (Wiki: NLB)  looks like it may be a way to combine two or more ISPs for an overall bandwidth increase and/or redundancy.  This might have prevented the VOIP call dropout I just experienced.
Link aggregation (Wiki)
The Cicso RV345 looks interesting. Could not find anyone for pre-sales technical questions after 4 phone calls: no answering machine, closed, busy, unactuated. (Maybe due to Covid?)

2021 Dec 20 - Unplugged the WISP cable from the above DGS-108 switch and plugged in a LAN cable coming from the AUX port on the Starlink router. 
Noticeable things:
  • All my email downloaded in the blink of an eye.  Not the tens of seconds to a minute when using 12 Mbps WISP.  Also there were no doubled emails.
  • Uploading web pages using filezilla also happens in the blink of an eye.

Severe Outage Jan 27 2022 @ 10:00 (+/-) pm.

While watching a movie the connection failed.  After powering down and restarting the Roku device the outage continued.
Checked computer and there was no internet connection.
The Android app (with Starlink as the WiFi source) showed a 22 minute outage (see screen shot below).

Severe Starlink Outage Jan 27 2022 @ 10:00
                      (+/-) pm
I tried unplugging the router and restarting it, but to no avail.
This was a mistake since that erased the outage information. 
It would have been better to just go to bed.

The next morning it had come back.

I live within a few miles of wildfires that have occurred for the past few years and a reliable internet connection is necessary to know what's going on.

Waiting for answer from Starlink about expected outage times.

I would think that server maintenance could be down without shutting down the system.  I.e. have a backup server that's swapped with the active server so an outage of a few seconds when they are switched.
2022 March 9 - Speed test will not run on Android with Starlink connected as WiFi

WiFi Dropouts

I use a number of WiFi devices and have in addition to Starlink WiFi routers based on WISP and DSL service providers all running in parallel.  If a device is registered with all of them whenever the primary source of WiFi drops out the device will automatically switch to another WiFi source.  Pretty much every morning (21 Jun 2022) Starlink is no longer the WiFi service and needs to be reset.  I plan to post again if I see Starlink on multiple days in a row.

On the web page Outage is showing 1 second and quality 99%. (21 June 2022).


As described in the patents the system can be implemented in a number of ways.  It's my understanding the phase I is almost complete as of Dec 2021.  The web viewer is showing:

AST Space Mobile

This is a similar Low Earth Orbit technology except the user link is compatible with standard cell phones instead of at X-Band like Starlink.
Because of the LEO the latency will be similar to Starlink, i.e. very low compared to first generation 2-way satellites that were in stationary orbits.
But the 10X frequency difference means the AST Space Mobile satellites will be huge (8m x 8m) compared to the Starlink satellites approximate size of 3.2x1.6x0.2m.

  SUPER FAST INTERNET on a BOAT with STARLINK - Sink or Swim 219 -
1. Can you tell us if it continues to work as the boat moves about? (BC: since the GPS will tell the dish it's location it should work, but I've read that it only works in a small area.)
2. Does the dish physically move as the boat turns?  (BC:  I expect the dish to point North so it should turn as the ship turns.  There may be a limit to how fast it can pan and tilt so probably will only track in calm seas.)

This may be an option for people with RVs.
