Longest range DigiMesh modem/modules


I need to build a network for vehicle tracking in large terrains.

I plan to place fixed solar repeater towers every 5 Km. And i’ll have vehicles moving within this repeater stations areas. I need live position info.

I don’t need large bandwidth. I need large coverage, so i’ve chosen 900Mhz.

I’m not sure on which of the technologies to adopt.
Should i choose the 900HP 10Kbps ? 900HP 200Kbps ? XTend ? Digi XLR PRO ?

I thought of using the 900HP 10Kbps modem in DigiMesh mode, so the fixed stations can act as repeater nodes (i don’t need the vehicle node to act as a repeater, although it would be nice), and i can get up to 15 Km of coverage. But i was told that the 900HP in 10Kbps mode doesn’t work in DigiMesh topology.

Is the 900HP 10Kbps really incompatible with DigiMesh ?

Can i buy a 10Kbps module and update it to 200Kbps later ? (is it just a firmware difference)?

What about the programmable modules ? Is there a hardware difference ? Can i buy a 900HP 10Kbps module and update it to a 200Kbps programmable ?

Digi documentation is very confusing and there are so many options.
A comparison table would be very helpful.

Any hints ?

Thanks !

For something like this, it would be best to contact Digi Sales so they can get you in touch with a sales Engineer.
