Wireless data from every light

Visible and near-infrared light represents a readily available and very large source of wireless spectrum beyond the traditional radio spectrum. Enter LiFi, a technology promising speeds in excess of 100Gb/s delivered via solid-state lighting, such as light-emitting diodes (LEDs). This enables high-bandwidth data signals to be transmitted without wires, while not being subjected to or contributing to electromagnetic interference (EMI) below 3THz. The technology also has great potential in applications where security is a concern.

Cost and compatibility can make a compelling case for pushing 100Gb/s bandwidth over a single optical channel, both as individual links and supporting 400Gb/s Ethernet, finds Andy Extance

Technological advances to aid the increasing demand for bandwidth, on the path towards the terabit network, should lead to optical signals that are flexible and adaptive, like water, argues Dr Maxim Kuschnerov
