The report that IMST provides as the output from LoRaWAN Radiation Performance measurement gives antenna diagrams showing the minimum and maximum values for the TRP (Total Radiated Power) and TIS (Total Isotropic Sensitivity). Based on these figures, a network operator can grade devices and ensure a good and smooth network availability and performance. Within development these measurements would help manufacturer to improve their designs.

Every LoRa end-device needs to be ETSI EN 300 220-2 (regulatory approval) compliant before it can be sold in the European Union. The declaration of conformity (DoC) is according to directive 2014/53/EU. For the 868 MHz ISM band, the main requirement is that the device should not radiate more than 14 dBm (or 25 mW) effective radiated power (ERP) for any orientation. RF-performance measurements ensure that the device actually radiates as much power as possible to maximize the robustness and usable data rate of the uplink, while not exceeding the 14 dBm.  


LoRa RF Performance Overview

  1. For official LoRaWAN RF-performance measurements, one needs to be a member in LoRa Alliance. If any assistance is needed by registering, you may contact the Alliance. Contact details: .
  2. Pre-Compliance measurements or measurements with different parameters may not require a LoRa Alliance membership.
  3. Contact IMST for a quote. Fill in the questionnaire (sections 01 to 06) and send it to
