IP Bridge using existing STL antenna's

Z

zachmorton

I post this as a research project primarily, but also because I'm trying to find a better way to get IP to my tower sites without having to climb the tower each time a lightning strike happens. The idea would be to share the STL dish that is already up on the tower, and sombine the ip radio with the signal being sent up already by the STL.

Any suggestions that you may have regarding this would be helpful. Ubiquity makes a great radio for long range ip bridging, however, those radio's typically go up the tower along with the antenna. One lightning strike and i'm down. At least if it happens with a radio on the ground, I can troubleshoot/change the radio out if it should be damaged.
 
If the IP system operates near the 950MHz range, you can use the STL dishes to carry the IP data as well as your station audio.
One very important thing to consider is the system RF loss. Your existing STL signal strength at the receiver will be reduced quite a bit.
Likewise, the signal strength of the IP data system will be reduced.
 
that's what worries me. i have a shot that is 22 miles in distance...uses 6' Mark dishes on each end. I get a really good receive signal at the other end on 950 stl, but don't know what it'll do if i add more to it.
 
Thought about using one of those little 4g boxes that use cell network...problem with that is, it is primarily going to be used for my remote control logging back to the studio site...so very data heavy.
 
If it's only for logging, it may not require a continuous data flow.
Is dial-up out of the question?
 
it is at this point...the phone circuits are horrible out there.
 
I'm doing some continuous streaming from Seattle to Louisiana, using Hughesnet's 4G service in an area where DSL and cable aren't available, and a T1 starts at $900/mo. The satellite has worked much better than I had expected.
 
We have two hops something along these lines. The 900mhz IP is only about 5 miles, so you could pick it up with nearly anything. Happen to be using 16" panels tho.
The other hop is currently running on a Verizon hotspot. You may need a different carrier, but nowadays it's a pretty good bet one of the 'Big Companies' will have a version that has both decent rf and low bit loss to your remote location. Most seem to run about 60$ a month or so. Once you've tried out the toys and found one that will actually get good b/w from the internet consistently at your site... Use either a router that will play with your Hotspot box (We use Verizon with USB to a Pepwave) or set up a pc to share the connection, if you have other equipment in the rack that's networkable. Then go to one of the Dynamic DNS providers (like, strangely DynDNS) ... and you can hit it remotely from anywhere. Seems a bit Rube-Goldbergish at first, but can be made to work fairly well. Control transmitters, change stuff, etc.
