Communication and Location-based Services using visible light
In indoor scenarios, such as meeting rooms, exhibitions, museums or, even, homes, a huge demand on communications and location-based services (LBS) is expected in near future, mainly motivated by the emerge of the Internet of Things (IoT) era. One of the technologies called to play an important role is the one based on visible light, that is leveraged on the technological advances in Light Emitting Diodes (LED). Optical signals are much more immune to multipath than GHz-band radio signals as the strength of the direct path is stronger than the diffused components. In addition, and in contrast to radio waves, light does not pass through walls. Therefore, with minimal cautions to avoid leakage from windows, etc., security is fundamentally enhanced, compared with RF systems. In this context, this research line involves Visible Light Communication (VLC), which promises data transfer speeds up to gigabits per second (Gbps) and is increasingly being deployed commercially in recent years, as well as Visible Light Positioning (VLP), which allows the implementation of LBS. Special interest is focused on applications from these technologies, including LiFi networks, augmented reality in places such as museums (downloading of further information about the object being viewed from the light that illuminates the exhibit), or interconnection of IoT devices. In this last case, the lighting widely available at homes and buildings can be used as communication nodes (linked to Power-Line Communications), thus facilitating the interconnection of, not only devices such as TV sets, computers or Hi-Fi, but also other common appliances, such as fridges, washing machines, microwaves, vacuums, etc. This type of network can be involved and become very useful to implement applications related to energy consumption, such as «power demand forecast» for energy saving, or «Ambient Assisted Living (AAL)» whether the house tenants’ behaviours can be derived from the appliance usage.
