a first wireless communication unit of the plurality of wireless communication units communicates through a Radio Frequency, RF spectrum; and
a second wireless communication unit of the plurality of wireless communication units communicates through a visible or infrared Light spectrum,
wherein the ALCU is configured to manage the plurality of wireless communication units based at least in part on first network measurements associated with the user equipment communicatively coupled to the WAP and collected through the plurality of wireless communication units,
wherein the ALCU collects information related to a communication link between the WAP and a user equipment, the information including one or more of:
the Bit Error Rate, BER of the communication link:
the spectrum efficiency of the communication link;
the signal bandwidth of the communication link;
the Signal to Noise Ratio, SNR, of the communication link;
the Signal-to-interference-plus-noise ratio, SINR, of the communication link; and
the received signal strength of the communication link,
and wherein the ALCU is configured to control operation of the plurality of wireless communication units based on the collected information to improve one or more of:
the Bit Error Rate, BER;
the spectrum efficiency:
the signal bandwidth;
the Signal to Noise Ratio, SNR; and
the Signal-to-interference-plus-noise ratio, SINR; and
a Cognitive Control Unit (“CCU”) communicatively coupled to the ALCU of each WAP and configured to manage the plurality of WAPs,
wherein the CCU is configured to manage the plurality of WAPs based at least in part on second network measurements associated with each WAP and transmitted to the CCU by the ALCU of each WAP, to improve the performance of the network of the plurality of WAPs,
wherein the CCU is arranged to receive from each ACLU the collected information related to the respective communication link, and wherein the CCU is configured to control operation of the plurality of WAPS based on the received collected information to improve one or more of:
the balance of the network load between the plurality of WAPs;
the configuration of the WAPs to provide redundancy communication links; and
the number of active radio and visible/infrared light transmitting/receiving elements in a WAP.
2 . The networking system of claim 1 , wherein the CCU is integrated in one of the plurality of WAPs forming the system.
3 . The networking system of claim 1 , wherein the CCU manages the plurality of WAPs by training a neural network based on the information collected from the ALCU of each WAP.
4 . The networking system of claim 1 , wherein the plurality of WAPs are communicatively coupled in a star topology and centrally coordinated by a central node that comprises the CCU.
5 . An In-Flight Entertainment and Connectivity (“IFEC”) system for an aircraft comprising a networking system according to claim 1 .
6 . The networking system of claim 1 , wherein:
the first wireless communication unit is communicatively coupled to one or more RF-end points wherein each RF-end point comprises at least one antenna for RF communication; and
the second wireless communication unit is communicatively coupled to one or more light-based end points, wherein each light-based end point comprises at least one visible or infrared light emitter for communication through the visible or infrared Light spectrum.
