The RSL15 offers four distinct value propositions. First, intelligent power. The RSL15 exhibits world-class low power consumption on the order of ~200 nA while in sleep mode, as well as excellent transmit and receive power yielding greater than 10-year coin cell battery life, depending on the conditions. Next, security. The RSL15 adopted TrustZone and CryptoCell-312 security directly from Arm®. Third, direction finding. The RSL15 supports real-time location services with angle of arrival (AoA) and indoor positioning systems with angle of departure (AoD). Finally, long-range. The RSL15 supports long-range coded PHY, effectively increasing the communication range by 4x compared to BLE 5.0.
