1. A system for enabling high-speed file transfer via a high-speed Li-Fi link between a user-held apparatus and a remote device, the system comprising:
the user-held apparatus comprising a first transmitter, a Li-Fi transmitter a first user interface, UI;
the remote device comprising a second receiver, a second Li-Fi receiver a second UI; and
wherein the user-held apparatus is configured to:
send a trigger signal from the first transmitter to the remote device for setting up the high-speed Li-Fi link upon receipt of a trigger command via the first UI; and
the remote device is configured to:
provide a human perceivable indication via the second UI about a dedicated reception area on the remote device upon receipt of and in response to the trigger signal by the second receiver, to assist adjustment of a position and/or an orientation of the user-held apparatus to point the Li-Fi transmitter to the dedicated reception area;
provide feedback on an alignment status between the Li-Fi transmitter in the user-held apparatus and the dedicated reception area; and
the user-held apparatus is further configured to:
transmit a file from the Li-Fi transmitter to the second Li-Fi receiver in the remote device via the high-speed Li-Fi link when the alignment status provided by the remote device is determined to allow for file transfer, or a start-to-send command is received via the first UI; and
wherein the trigger signal sent from the first transmitter is via another optical link different from, and with wider beam width than, the high-speed Li-Fi link.
