Dialog Semiconductor Delivers WiRa Technology to Princess MedallionClass Wearable Devices

Dialog Semiconductor has announced to deliver its WiRa-enabled solution to enhance Carnival Corporation’s OceanMedallion wearable devices for proximity-based locationing to help ensure passenger safety and offer enhanced cruise services. To implement WiRa and advanced multipath cancellation, Carnival selected DA14697 Bluetooth LE SoC.  In addition to Dialog’s DA1469x Bluetooth LE SoC, Carnival also selected Dialog’s AT25FF series SPI NOR Flash and SLG46108V GreenPAK technology. 

The winning combination of Dialog Semiconductor’s Flash, GreenPAK and Bluetooth LE technology will enhance the Princess MedallionClass experience. Dialog’s WiRa technology offers fine-grain, phase-based ranging performance approaching UWB (ultra-wideband) accuracy. Besides, it uses significantly low power thereby extending battery life, and lowering solution cost, including advanced and proprietary algorithms to deliver enhanced performance. This is especially important on ships built from steel, where wireless signals are easily reflected, which can cause errors in distance estimation and require advanced, multipath cancellation techniques. 

Utilizing Dialog’s WiRa technology, the OceanMedallion enables higher accuracy ranging between Medallions compared to RSSI (Receive Signal Strength Indication) based technology. The AT25FF offers an ultra-deep hibernation mode, consuming less than 7nA for extended battery life. The SLG46108V, GreenPAK technology maximizes the Bluetooth LE SoC’s sleep time, further increasing battery life, while also reducing the PCB area needed.
