How to do multiple canopy hops?

[wavetar]

In let's say an IP Site Connect system, if one wanted to connect site A-to-B, then B-to-C, then C-to-D with say PTP300 series equipment, how would it be done? Is there a 'sync' unit similar to the CMM/Micro to accomplish this with the higher tier stuff? The PTP300 user guide makes no mention of anything beyond a single PTP link...which is all I've done with it.

I took Canopy training way back when it first came out, but of course it's all now completely different, and I've only dealt with it in fits & spurts.

Anyone have any experience with the RAD Airmux stuff...how it works & compares price-wise vs. Canopy?

In a bare bones ip microwave configuration (site connect or not), use a switch between Canopy devices at sites B & C. In an IP site connect, you have switches at every site.

Forgot to add about RAD AirMux. It is slightly lower cost and works just fine. I have not seen any options for syncing them if you run into interference issues at busy sites.

Wouldn't there need to be syncing involved at sites B & C if I'm trying to use a couple of PTP54300 for all links at the sites?

Not necessarily if there were natural ways to prevent interference by keeping the paths physically separate. If you can prevent a receiver from hearing another path by using natural obstructions, you will minimize self interference without sync.

Greater than 90 deg apart on the same leg.
Ants with high performance rings if you are between 50 and 90 deg at similar elevations.
Much different elevations on the same leg.
On two sides of tower using tower clutter to obscure one path from another.
Assign channels.
Two ends of a building.
Over the side parapet mounts on two faces of a building.

Ok, thanks. We're looking at same leg with not much vertical separation, but we can easily do the 90-degree or better, and assign channels.

Integrated antenna or connectorized? You get better isolation with connectorized because greater backside rejection from a dish than a panel.

Todd,
We have used alot of AirMux stuff to link our Passport network together. It is inexpensive, reliable, easy to setup....

What got me onto AirMux was that it had both Ethernet and T1 built-in.

I've always got the connectorized version and used parabolics for maximum interference rejection. It has a built-in synchronization port for high density sites but I have never used it. I believe you just setup one unit to be the Master and the rest sync to it at the same site.
