The lamp now provides an Ethernet 10Base-T transmission over a Non-Directed Line-Of-Sight (NDLOS) link in an environment with strong background light (up to ∼3000 lx) and high tolerance to misalignment (up to 45 degrees). The system operation has been tested with packet loss measurements of randomly generated packets and with Bit Error Ratio (BER) measurements of an Ethernet-equivalent 12.5 Mbit/s transmission of a Manchester coded OOK signal over a distance of 1 m in NDLOS. The proposed technology has been implemented into a commercial lighting equipment without any relevant modification of the lamps.","PeriodicalId":150652,"journal":{"name":"2018 Global LIFI Congress (GLC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130989014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is a typical use case in current VLC lighting systems. The lighting becomes a beacon to transmit its coordinates and other kind of information at low-transmission rates, typically 1 kbps. This can easily permit the smartphone's camera to get and decode the message. Transmitting information by light can decrease the luminous emittance because of off-state used to transmit logic zeros. Here, we have modified the transmission code to increase lighting efficiency while continue to use light in transmissions.","PeriodicalId":150652,"journal":{"name":"2018 Global LIFI Congress (GLC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115972094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their properties are suitable for the ADAS (Advanced Driving Assistance System) applications on smartphones. In this paradigm, a smartphone need to connect with the sensitive information of a vehicle. The quality of this data exchange is an important issue. To do this, we design and implement a VLC system that uses two components: a modified reading light and an USB optical transceiver. In our paradigm, these two components are fixed inside a vehicle. This constrained mobility is suitable for our VLC system. Comparing RF communication, our VLC system provides a stable short range communication with limited transmission power and LOS property. This is an ideal candidate to achieve a stable, secure and private data transmission for ADAS applications. In this work, a VLC for prototype based on commercial LED is presented and tested. This experimental study has proved that our VLC prototype is realistic for providing a good enough quality of the data link and can run on resource-constrained platforms.","PeriodicalId":150652,"journal":{"name":"2018 Global LIFI Congress (GLC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116725434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
