LAUNCHXL-CC1352P: Sub 1GHz range estimation

Part Number:LAUNCHXL-CC1352P

Dear all. My team is trying to build an automatic weather station (AWS, not Amazon Web Service)-like product using either

Sub-1 GHz (LAUNCHXL-CC1312R1) / LoRa / SigFox / NB-IoT. I'm just investigating Sub-1GHz so I'm a beginner.

HDC2080DMBT, OPT3001DNPT is used. These data are collected every 1 second and these will be transmitted to the cloud.

This product, which acts as an AWS sensor node, will be installed under bridges located in

- Bon Wier, TX 75928

- Huntsville, TX 77340

- Galveston, TX 77514

- Houston, TX 77005

- El Paso, TX 79905

Considering the distance between Bon Wier, TX 75928 to El Paso, TX 79905, which is nearly 900 miles (1448.41 km),

I'm worried whether this device can communicate via 915MHz.

Although I was informed to use the range estimator from TI,

I cannot apply my situation clearly. Suppose I have added external antennas to the launchpad and configured the 20 dBm PA.

I'm considering this antenna.

If I add one of these antennas to the launchpad, will I be able to see two devices communicating, considering the distance between the 2 locations?

How should I use TI's estimator for solving this concern?
