Another vote for using a private Ubiquity radio link to the spot with line of sight and putting your internet drop there. Should be excellent compared with the current unacceptable situation.

If you haven't worked with a wireless ISP before, just be prepared for some variation in data rates in the shared infrastructure, and for other path-related slowdowns or even dropouts at times. The weak link will be the wireless ISP connection, not your private four mile hop. Even with what in my experience are typical wireless ISP issues, this will be a far better solution than either of the previous ones, if the wireless ISP delivers on their promises better than the DSL provider did.

Big "if", in my experience.

Agreed that the UBNT (Ubiquiti Networks) stuff will likely be what you need.  https://www.ubnt.com/airmax/nanobeamm/


Here is an interesting use of UBNT:  https://arstechnica.com/information-technology/2015/11/how-a-group-of-neighbors-created-their-own-internet-service/

Absolutely feasible if there is line of sight between the tower site and the facility.  For 14mbps the cheap UBNT stuff should work fine.  I would suggest going with a little taller tower to get some spacing between the WISP rx antenna and your relay antenna AND/OR use a different band for your relay. 

If it isn't an RF congested area, do your link on 2.4ghz OR if you can get some vertical spacing, use as widely separated channel as you can find on 5ghz for the relay to the facility.  This assuming that there is line of site between the relay tower and facility.  2.4 will work thru obstructions that 5ghz will not.


About $150/end (or less) for the UBNT equipment plus a good rugged network switch at the relay tower.

The solar or wind power will be your biggest challenge and expense...  In that area, a combination of wind and solar may be your best bet if there is no possibility of getting a power cable plowed, hung, trenched, thrown, laid, etc between the facility and relay tower.  I am assuming that there are extended periods of overcast sky.  The solar maps indicate a horrible average of 3.5hrs/day of sunlight...  You will still get _some_ charge even during overcast periods but it will be minimal.

I have used the solar system calculator at: 


for a few small solar systems here on the Radio Ranchito.  Size your panels and charger to take advantage of the relatively short charging periods and size your batteries to cover the longest conceivable period of no direct sunlight.  AND make provisions to hook up a generator or vehicle to charge batteries as a backup.  If there is sufficient wind power available, then that may be an option as well.

Good luck,

I'm back, at least for a little while. I have missed my friends here on CRTech. I hope you all are well. I am enjoying retirement, but every now and then, I get pulled back to the real world. I have been asked to assist some folks with getting Internet access to a remote facility. This project has been a real struggle, and I think I have a solution, but I don't know for sure how to implement it. Then, I thought of my friends here on CRTech and am sure I can get help here. Although this is not broadcast related, I'm sure some of you have faced and beaten the same problem.

Here's the deal. This facility is in a rural area in Northwest Oregon. They are on a large, mostly wooded, piece of property in the hills overlooking the Columbia River. They struggled with DSL for a number of years, but the service was unreliable and the bandwidth was dismal. A "consultant" talked them into getting Internet via satellite. The service was little better than DSL and they ran into unexpected data caps. They had great service for a week, then hit the data cap and the bandwidth was reduced drastically until the end of the month. The service cost is exorbitant, and they got stuck with a horrible contract with severe penalties if they try to discontinue service. They are finally nearing the end of their contract and are looking for new solutions.

I found a wireless Internet provider in Washington who can provide cost effective Internet access up to 14mbps. The problem is lack of line-of-sight access to the facility. However, there is a location on the property that does have an excellent view to Washington and can easily receive the wireless signal on 5 GHz. The actual point-to-point view to the provider is just under four miles. This point is approximately 2000 feet from the facility and there simply is no way to run any kind of cable between the two locations. My intent is to put some kind of repeater at the access location. I envision a tower of about 20-30 feet with a dish pointing across the river to get the 5GHz wireless signal, then another small dish and radio to relay to the facility. This repeater will need to run from battery with solar and possibly wind power for charging.

What I am looking for from my friends here on CRTech is first, does this sound feasible? If so, I am looking for recommendations and sources for the radios and antennas for the link between the tower and the facility as well as solar panels, wind generators, batteries, controls, etc. The ISP will provide the equipment for the link to their system, which basically is the dish, radio, and modem/router. I don't have the full power requirements for them, but it shouldn't be much.

I know some of you have faced similar issues getting Internet and/or STL to geographically challenged transmitter sites. And, many of you know how to work with limited budgets. I look forward to hearing about your innovative solutions to this problem.

Thank you, my friends,
