MultiNav Pro+ BLE 50km range - line of sight only or does it work in urban?

Elizabeth Jones•June 23, 2026

So I've been spec-ing out a long-range asset tracking build and the 50km BLE range on the MultiNav Pro+ caught my eye pretty hard. I get that range claims like that are usually under ideal conditions - flat terrain, clear line of sight, elevated antennas, etc. - but I'm trying to figure out how much of that holds up in a more realistic semi-urban or suburban environment where you've got buildings, trees, maybe some rolling hills in between. Has anyone actually deployed these in a non-ideal RF environment and measured what kind of range they're actually getting?

@Elizabeth Jones good question, and honestly a really important one to nail down before you commit to a build.

The 50km figure is drone-to-drone, both units elevated — that's the clean-sky, no-ground-reflection scenario. For your use case, the more relevant number is probably the 5km ground-to-ground spec, and that assumes reasonably open terrain. In a semi-urban or suburban environment with buildings and trees breaking up the Fresnel zone, you're going to take a hit on that — how much depends a lot on your specific deployment geometry.

That said, a few things that make a real difference: antenna elevation is huge even in urban environments, so if even one end of the link can get above roofline level (rooftop mount, elevated pole, whatever), you recover a lot of range. Rolling hills are actually less of a killer than dense building clusters, because you can sometimes get diffraction around terrain that you just can't get through concrete.

I haven't personally tested in your exact environment, but my honest advice for an asset tracking build in mixed urban terrain would be to treat 1-2km as your conservative working assumption for ground-level nodes in populated areas, and design your mesh topology around that. The good news is at $59 for two units, running field tests before you commit to full deployment is actually pretty reasonable — that's not the case with most long-range hardware that could hit these numbers.

Real talk - in semi-urban you're probably looking at 10-15% of that spec range on a good day, maybe a bit more with elevated anchor points and clear sightlines between buildings. I did a suburban PoC last year with similar hardware and we were getting solid links out to about 6-8km before packet loss got ugly, which honestly was still plenty for the use case. Worth bench-marking your specific environment tho before you commit the architecture to it.

John's numbers track with what I've seen too - we ran some tests in a mixed suburban/light industrial area and honestly the link quality dropped off way harder than the range did, like you'd still *have* a connection at 8km but the RSSI was all over the place and retries were killing our update intervals. If you've got any control over anchor placement, getting even 3-4m of elevation made a noticeable diff in our case.

Echoing what John and Jessica said - also worth factoring in that BLE at those ranges is gonna be pretty sensitive to interference from WiFi and other 2.4GHz stuff in urban/suburban areas, which can tank your effective range even when you've got decent LOS. If your use case allows it, pairing the BLE with the GNSS fallback for the gaps might save you a headache down the road rather than trying to squeeze every meter out of the RF link.
