What is some real long range ( 1km - 5 km) communication module

>>1118084
Im a total noob at this anon, but when i was looking to rig up some remote sensors i bought a HopeRF HM-TRP radio module. Google it. It comes in quadcopter telemetry kits. I have yet to figure it out as i have been busy with other stuff but maybe someone smarter than I can figure it out quickly.

It says over 1km transmission , and works with 915Mhz and 100mw(20dbM) . Do you know at wich voltage it works on maximum range?

If it has to work in an urban environment, use a mobile network modem.

LoRa/CC1120/etc won't go 5 km in a dense urban environment.

with paket radio over ham radio some friends realized a (slow) long distance data communication over many kilometers between 2 towns. what i want to say is that this is also a question of the application and the boundary conditions (power available, antennas, bandwidth you need, ....).

in most cases the best option will be a gsm module when applicable and satisfactory.

Im sorry, I dont. I believe you need to change the antenna for ranges over 1 mi, but for under 1 mi it works off of usb power. (4.4V?)

LoRa beats all.
Just make sure the chips are not knockoffs.

I've been using these from nicerf.com for years.
They're based on original sx1278 chips.
