With reference to Visible Light Communication (VLC) technology, which ...
Visible light communication (VLC) is a data communications variant which usesvisible light between 400 and 800 THz (780–375 nm). VLC is a subset of optical wireless communications technologies. 1 is correct.
The technology uses fluorescent lamps (ordinary lamps, not special communications devices) to transmit signals at 10 kbit/s, or LEDs for up to 500 Mbit/s over short distances.
Systems such as RONJA can transmit at full Ethernet speed (10 Mbit/s) over distances of 1–2 kilometres (0.6–1.2 mi). It is not long range. 2 is incorrect.
VLC has the characteristic, to resist electromagnetic interference. 4 is correct.
It carries more data than WiFi and bluetooth. 3 is correct.

Visible Light Communication (VLC) Technology
Correct Statements:
1. VLC uses electromagnetic spectrum wavelengths 375 to 780 nm.
2. VLC is known as long-range optical wireless communication.
3. VLC can transmit large amounts of data faster than Bluetooth.
Explanation:
• VLC technology uses visible light to transmit data wirelessly.
• The correct statement is that it uses electromagnetic spectrum wavelengths 375 to 780 nm which are the wavelengths of visible light.
• VLC is known as a long-range optical wireless communication system because it can transmit data over long distances using visible light.
• VLC can transmit large amounts of data faster than Bluetooth because it uses the visible light spectrum which has a higher bandwidth than the radio frequency spectrum used by Bluetooth.
• However, VLC has some limitations such as the requirement of a clear line of sight between the transmitter and receiver and the interference caused by ambient light sources.
• The incorrect statement is that VLC has no electromagnetic interference. Although VLC does not interfere with radio frequency devices, it can be affected by other sources of electromagnetic radiation such as fluorescent lights.
Conclusion:
The correct statements about VLC technology are that it uses electromagnetic spectrum wavelengths 375 to 780 nm, is known as long-range optical wireless communication, and can transmit large amounts of data faster than Bluetooth. The incorrect statement is that VLC has no electromagnetic interference.
