Systems and methods for enabling high-speed wireless file transfer

A user-held apparatus for enabling high-speed file transfer to a remote device via a high-speed Li-Fi link, the user-held apparatus comprising:

• a first user interface, UI, configured to receive a trigger command;
• a first transmitter configured to send a trigger signal to the remote device for setting up the high-speed Li-Fi link upon receipt of the trigger command, wherein the remote device has a second user interface, UI;
• a Li-Fi transmitter configured to transmit a file to a second Li-Fi receiver in the remote device via the high-speed Li-Fi link, when an 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,
• wherein the remote device provides 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, 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.

A remote device for accommodating high-speed file reception from a user-held apparatus via a high-speed Li-Fi link, the remote device comprising:

• a second receiver configured to receive a trigger signal from the user-held apparatus for setting up the high-speed Li-Fi link;
• a second user interface, UI, configured to provide a human perceivable indication about a dedicated reception area on the remote device, upon receipt of and in response to the trigger signal;
• a second Li-Fi receiver configured to receive a file from a Li-Fi transmitter in the user-held apparatus via the high-speed Li-Fi link;
• and
• wherein the remote device is further configured to provide a feedback on an alignment status between the Li-Fi transmitter comprised in the user-held apparatus and the dedicated reception area;
• and
• wherein the trigger signal received by the second receiver is via another optical link different from, and with wider beam width than, the high-speed Li-Fi link.

A method of a user-held apparatus enabling high-speed file transfer to a remote device via a high-speed Li-Fi link, the method comprising:

• receiving a trigger command via a first user interface, UI;
• sending a trigger signal from a first transmitter to the remote device for setting up the high-speed Li-Fi link upon receipt of the trigger command, wherein the remote device has a second user interface, UI;
• providing, via the second UI, a human perceivable indication about a dedicated reception area on the remote device upon receipt of and in response to the trigger signal, 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;
• and
• transmitting a file from a Li-Fi transmitter to a second Li-Fi receiver in the remote device via the high-speed Li-Fi link, when an 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.
