The Radius® SDK for native Android and native iOS, along with the React Native wrapper provides a function called setTransmissionVolume which allows the developer to set the transmission volume between 0-100 percent.
By default, the Radius® SDK broadcasts all tones, regardless of tone profile selected, at 100% volume. Reliability may be impacted if a broadcast volume of less than 100% is set. We recommend broadcasting at 100% volume, but provide the option to choose your own broadcast volume. The below chart can be used as reference when choosing a value less than 100%:
Volume Level | Zone66 Effective Distance (Feet) | Point1000 Effective Distance (Feet) |
20% | 2.5 - 5 | <1 inch |
40% | 20-30 | 1.5 - 2 |
60% | 40 - 50 | 2 |
80% | 70 - 80 | 2 |
100% (Recommended) | 70 - 80 | 5 |
