How does the backhaul work?
There are two solutions for providing backhaul for LiFi wireless communications.
Currently, power over Ethernet (POE) is the optimal solution for driving the network backhaul and therefore the preferred option for new installations. Power line communications (PLC) is the preferred option for retrofit installations. PLC can be used for by sharing the available capacity between lamps attached to any given ring main.
The long-term backhaul is resolved by using Power over Ethernet in new offices, which is proving more efficient for smart buildings and lighting. An example is the Edge Building in Amsterdam that is the current headquarters of Deloitte. The building has over 6,000 PoE connected lighting fixtures, which resulted in a 50% reduction in installation time as well as a 25% installation cost saving. This is the future.
Enabled by pureLiFi technology, the “Cloud RAN” architecture can also help alleviate the pressure on the backhaul.
