PHY modes within IEEE 802.15.7m draft – a quick review

PHY operating modes  The latest IEEE 802.15.7m draft standard (until Aug. 2018) is on the Sponsor Balloting recirculation. This version has updated a lot in compared to the previous version before LiFi modes are moved to new task group under IEEE 802.15. A list of operating modes between two drafts is a good start. Notation … Continue reading PHY modes within IEEE 802.15.7m draft – a quick review

OCC Standardization Roadmap

OWC Standards under IEEE 802 There are IEEE standards covering the optical spectrum, IEEE 802.15.7-2011 std., known as VLC IEEE 802.15.7m std., (publication in 2018, as expected), including OCC modes IEEE 802.15.13 std., (ongoing), adding LiFi (IEEE 802.15.7-2011 std. is also the base document as IEEE 802.15.7m) IEEE 802.11, introducing LiFi to 802.11 IEEE 802.15 … Continue reading OCC Standardization Roadmap

OCC Use Cases/ Promising Services

Figure 1 - Examples of promising use cases using OCC Various application fields of OCC include Indoor lighting Digital Signage Traffic lighting, V2V, V2X Interactive Display with Screen Augmented Reality experience with Smartphones There are plenty of promising applications with OCC. I have drawn several illustrations to explain "where OCC can be used" and "how … Continue reading OCC Use Cases/ Promising Services

Classification of OCC Technologies

Table 1- Classification of OCC, its expected performance, and intended usages Given that various modulation schemes for OCC systems have been investigated till the date, the proper modulation scheme should depend on both Tx and Rx. Table 1 suggests to classify OCC schemes into four categories under the following considerations: (i) The method by which … Continue reading Classification of OCC Technologies
