This Page provides information about NB-IoT Link budget calculator. Сalculator allows to calculate the maximum Link budget of NB-IoT network depending on Cell Radius, eNodeB/UE configuration, Propagation model, attenuations, etc.
You can calculate the Link budget (Signal level at receiver) and then compare it with Rx Reception sensitivity. Then you will understand Radio Channel Status (Pass or Fail) and Cell Radius.
The calculation is based on the 3GPP 38.901 standard. Approximately Link budget of NB-IoT can be calculated using the formula:
Update1: Add Free Space Path Loss (FSPL) Propagation Model. Now you can use LOS or NLOS Model
