    In simple words. Consider your eyes – whatever you can see, is in your line of sight. Similarly, whatever is in the direct sight of anything, comes in it’s light of sight.
    In WiFi, you don’t need to place your phone in line-of-sight of router; similarly in Bluetooth and NFC.
    Whereas, in TV remotes, you need to point the remote to TV receiver in order to operate it – so it’s in line-of-sight. (Similarly in reading BarCode and QR-Code)

    It’s in phone generally. Was in OnePlus 1, Nexus 6P etc. Can be in PoS too.
    So bring two phones nearby, and transmit data. Used for payment services too – like in Google Wallet and Apple Pay and Samsung Pay.

    Long-distance data communication is more effective through wireless networks but geographical obstacles and the curvature of the earth bring limitations to line-of-sight transmission. However, these issues can generally be mitigated through planning, calculations and the use of additional technologies.

    For example, mobile phones use a modified line-of-sight transmission, which is made possible through a combination of effects like diffraction, multipath reflection, local repeaters and rapid handoff.
