Mine, too. Difficult to get these days. Once I touched the 16k Memory extension while programming and everything was gone .... I upgraded to the spectrum. Much later I got an ZX-80 which is the star of my home-office now.

Been a few years since I used ePMP anything. The UI used to be dreadfully slow.

The power requirement is going to limit you to wifi type stuff I think.

ePMP in PTP mode. You can get the itty bitty Force180 for $85 each and in PTP mode at that range you'll have somewhere near 200mbps aggregate. I'm sure there are half a dozen Ubiquiti things which will also suffice. The example ePMP below is at a range of .559 mile.

Too much power. I don’t want to exceed 20 watts total. So one end of a radio needs to be in the 5-7 watt range.

Then do a 24 GHz system. That can go 2-1/2 miles with 5 nines. Low interference. Will eat around 50 watts at each end though.

For so little throughput a 5GHz setup would be the cheapest and probably best setup.

What keeps you from being a believer of the 60GHz? I can show you the history of some of my Ignitenet links that may just change your mind.

Thank you, Brett A Mansfield

Not a believer yet. And we only need 100-250 Mbps max to the homes. Actually probably more like 50 or 100 Mbps. Want it to be simple too. ONT has multiple ethernet ports on it. Just extend those physical layer 0/1 connections.

What about a couple of 60GHz links with a single 5GHz AP as a backup? We did this for a bank that needed to connect two buildings temporarily. Put a MT on either side that ran IPSEC tunnel over the link with a failover script to route traffic over the 5 GHz link if the 60 lost more than 50% of it's packets. The 5 GHz was slower, but they still had connectivity in the even of a heavy rain.

Still puzzling over how to get ethernet the last 3000 feet. I have fiber to a point along a rural road. The end is about 2000 feet from one home and 3000 feet from another.

Was looking at using the existing copper with VDSL line extenders. That was what that week of math problems was all about. I am starting to lean away from that solution because it is old copper. I really want to stop using it.

I don’t have a ROW that is legal. The old copper technically is in trespass and the owner of the property is known to be a major PITA. So not sure if I can get permission. Even then, we are talking about 5000 feet of fiber to place. There will be some money involved.

Using wireless could be much cheaper. Will have to do a solar install with the ONT and RF gear on a stub pole at the handhole. Not sure what kid of RF. Don’t want to use an AP because I need two layer 2 connections from the ONT. Be more expensive to use an AP anyhow. So two PTP systems. Rock solid, never fail type of system. Noise floor down there is probably pretty low. I could use a pair of rockets etc. Not wanting to lo-ball this, want it to be very solid.
           What would you use?
