20.500.12556/RUL-187039 Natančnost in poraba energije pri merjenju razdalje s tehnologijo Bluetooth Channel Sounding Accuracy and Energy Consumption in Distance Measurement Using Bluetooth Channel Sounding Technology Bluetooth Channel Sounding (CS) je funkcija, ki jo je Bluetooth SIG s specifikacijo Core Specification 6.0 uvedel kot natančnejšo alternativo ocenjevanju razdalje na osnovi jakosti signala (RSSI). Za baterijsko napajane naprave pa natančnost meritve ni edino merilo – pomembna je tudi poraba energije. V diplomski nalogi smo zato razširili referenčno vdelano programsko opremo Nordic Semiconductor za platformo nRF54L15 Tag, tako da pobudnik meritve podpira sočasno povezavo z dvema odzivnikoma ter konfigurabilno uporabo ene ali dveh anten. Na tem sistemu smo eksperimentalno izmerili natančnost ocenjevanja razdalje in porabo energije pobudnika pri različnih konfiguracijah antenskih poti in oddajne moči. Meritve so pokazale, da več antenskih poti dosledno izboljša natančnost, hkrati pa poveča porabo energije, medtem ko vpliv oddajne moči na natančnost ni bil enoznačen; meritve pri sočasni povezavi z dvema odzivnikoma poleg tega niso pokazale jasnega poslabšanja natančnosti kljub višji porabi energije. Bluetooth Channel Sounding (CS) is a feature introduced by the Bluetooth SIG in Core Specification 6.0 as a more accurate alternative to receivedsignal-strength-based ranging. For battery-powered devices, however, ranging accuracy alone is not sufficient – power consumption matters as well. In this thesis, we extended Nordic Semiconductor’s reference firmware for the nRF54L15 Tag platform so that the initiator supports a simultaneous connection to two reflectors and configurable use of one or two antennas. Using this system, we experimentally measured ranging accuracy and initiator power consumption for different antenna-path and transmit-power configurations. The measurements showed that additional antenna paths consistently improved accuracy while also increasing power consumption, whereas the effect of transmit power on accuracy was not conclusive; measurements with two simultaneously connected reflectors likewise showed no clear degradation in accuracy despite the higher power consumption.
