Background
TGbr - Enhanced Light Communication (ELC), is a new Task Group within the IEEE 802.11 working group that
will address the problem of how a Station - STA (e.g. a Mobile Device), or multiples thereof, can communicate in the light spectrum
to another STA (e.g. an Access Point), or multiples thereof, thereby forming a network.
The Project Authorization Request is available here.
The Criteria for Standards Development is available here.
Goals
The scope of this standard is to define one medium access
control (MAC) and several physical layer (PHY) specifications for wireless connectivity for fixed, portable,
and moving stations (STAs) within a local area.
This amendment provides enhanced light communications (ELC) for Wireless LAN
operation. This amendment modifies the IEEE 802.11 MAC to support the ELC PHY and multi-link operation.
The amendment introduces an ELC PHY through the modification of IEEE 802.11 sub-7.25 GHz PHYs. These
modifications are limited to specifying:
- Operations in new optical bands in the range of 400 nm to 600 nm and 1200 nm to 1600 nm
- New channelization
- The use of wavelength division multiplexing (WDM)
- Simpler integration of the IEEE 802.11 baseband with optical frontends
- PHY support for existing ranging techniques
- Methods to reduce the peak-to-average-power ratio
This amendment modifies the IEEE 802.11 MAC to support the ELC PHY and multi-link operation.
This amendment provides for compatibility with legacy Light Communications (LC) IEEE 802.11bb devices as
defined in IEEE Std 802.11bb-2023™ operating in the identified optical bands.
The stakeholders include chipset manufacturers to deliver
PHY & MAC sub-systems, system integrators and lighting companies, telecom operators, Internet Service
Providers (ISPs), emerging IoT companies, large industrial manufacturers, aviation and transportation
industries.
