Parasitic communication protocol for radio-frequency wireless power transmission (IEC 62980:2022)

This standard defines procedures for transferring power to non-powered IoT devices using the existing ISM band communication infrastructure and RF WPT and a protocol for a two-way, long-distance wireless network in which IoT devices and APs communicate using backscatter modulation of ISM-band signals. Three components are required for two-way, long-distance wireless communication using backscatter modulation of ISM-band signals: an STA that transmits wireless power and data packets to SSNs by forming ISM-band signal channels between HIE-APs, a batteryless SSN that changes the sensitivity of the channel signals received from the STA using backscatter modulation, and an HIE-AP that practically decodes the channel signals whose sensitivity was changed by the SSN. In this standard, the procedures for CW-type RF WPT using communication among these three components are specified based on application of the CSI or RSSI detection method of ISM-band communication.
This standard proposes a convergence communication protocol than can deploy sensors, which can operate at low power (dozens of microwatts or less) without batteries, collect energy, and perform communication, to transmit power to SSNs using RF WPT based on parasitic communication. This method can be applied to application service areas such as domestic IoT, the micro-sensor industry, and industries related to environmental monitoring in the future

Parasitäres Kommunikationsprotokoll für drahtlose Hochfrequenz-Leistungsübertragung (IEC 62980:2022)

Protocole de communication parasite pour le transfert d'énergie sans fil par rayonnement radiofréquence (IEC 62980:2022)

L'IEC 62980:2022 définit les procédures de transfert d'énergie vers des dispositifs d'IoT au moyen de l'infrastructure de communication existante sur les bandes ISM et du WPT RF, ainsi qu'un protocole de réseau sans fil longue distance bidirectionnel qui permet aux dispositifs d'IoT et aux points d'accès de communiquer par modulation de rétrodiffusion des signaux sur les bandes ISM. La communication sans fil longue distance bidirectionnelle fondée sur la modulation de rétrodiffusion des signaux sur les bandes ISM exige trois éléments:
• une STA qui assure le transfert sans fil de l'énergie et des paquets de données vers les SSN en créant des canaux de signaux dans les bandes ISM entre HIE-AP ;
• un SSN sans batterie qui modifie, par modulation de rétrodiffusion, la sensibilité des signaux de canal reçus depuis la STA ; et
• un HIE-AP qui décode de manière pratique les signaux du canal dont la sensibilité a été modifiée par le SSN.
Dans le présent document, les procédures de WPT RF de type CW qui utilisent la communication entre ces trois éléments sont spécifiées à partir de l'application d'une méthode de détection des CSI ou du RSSI de la communication sur les bandes ISM.
Le présent document propose un protocole de communication convergent qui peut déployer des capteurs, lesquels peuvent fonctionner à faible puissance (quelques dizaines de microwatts ou moins) sans batteries, collecter de l'énergie et assurer une communication, afin d'alimenter des SSN au moyen d'un WPT RF fondé sur une communication parasite. Cette méthode pourra être appliquée ultérieurement à des services d'application tels que l'IoT domestique, l'industrie des microcapteurs et les industries impliquées dans la surveillance de l'environnement.

Lažni komunikacijski protokol za brezžični radiofrekvenčni prenos električne energije (IEC 62980:2022)

Ta standard določa postopke za prenos električne energije v naprave interneta stvari (IoT) brez napajanja z obstoječo infrastrukturo za komunikacijo prek radiofrekvenčnega pasu za industrijsko, znanstveno in medicinsko (ISM) uporabo ter brezžičnega radiofrekvenčnega prenosa električne energije (RF WPT), pa tudi protokol za dvosmerno brezžično omrežje na dolge razdalje, v katerem naprave interneta stvari in točke dostopa (AP) komunicirajo z modulacijo povratnega sipanja signalov v radiofrekvenčnem pasu. Za dvosmerno brezžično komunikacijo na dolge razdalje z modulacijo povratnega sipanja signalov v radiofrekvenčnem pasu so potrebne tri komponente: postaja (STA), ki z vzpostavitvijo kanalov radiofrekvenčnih pasov med HIE in točkami dostopa prenaša brezžično električno energijo in podatkovne pakete do SSN-jev, SSN brez baterije, ki spremeni občutljivost signalov kanala, prejetih od postaje, ki uporablja modulacijo povratnega sipanja, in povezava med HIE in točko dostopa, ki dekodira signale kanala, katerih občutljivost je spremenil SSN. V tem standardu so določeni postopki za brezžični radiofrekvenčni prenos električne energije z nosilnim valovanjem prek komunikacije med temi tremi komponentami, in sicer na podlagi metode zaznavanja CSI ali indikatorja moči prejetega signala (RSSI) komunikacije prek radiofrekvenčnega pasu za industrijsko, znanstveno in medicinsko uporabo.
V tem standardu je predlagan konvergenčni komunikacijski protokol, pri katerem je mogoče uporabiti senzorje, ki lahko delujejo z nizko močjo (več deset mikrovatov ali manj) brez baterij, zbirajo energijo in izvajajo komunikacijo, za prenos energije na SSN-je z brezžičnim radiofrekvenčnim prenosom električne energije, ki temelji na lažni komunikaciji. To metodo je mogoče uporabljati za področja uporabe storitev, kot so domači internet stvari, industrija mikrosenzorjev in industrije, povezane s prihodnjim spremljanjem okolja.
