Bluetooth 5 Measurement Specifications
Bluetooth 5 introduced a couple of new test requirements:
Data Rate: New requirements for testing with 2 Mbps, 1 Mbps, 500 kbps, 125 kbps signal
Stable Modulation: Optional requirement for device to support smaller variation in the frequency
deviation during modulation (modulation index between 0.495-0.505). This enhancement gives device stable and better range coverage and thus competitive advantage
