With reference to Visible Light Communication (VLC) technology, which of the following statements are correct? 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. 4. VLC has no electromagnetic interference. Select the correct answer using the code given below:

1. Statement 1 is correct. Visible Light Communication (VLC) utilizes the visible light portion of the electromagnetic spectrum, which corresponds to wavelengths approximately between 380 nm and 780 nm. The range 375 to 780 nm is an accurate representation of this band. 2. Statement 2 is incorrect. VLC typically operates over short distances, often within a room, requiring line-of-sight or reflection from surfaces. It is not considered a long-range optical wireless communication technology. 3. Statement 3 is correct. The visible light spectrum offers a vast, unlicensed bandwidth, potentially allowing VLC systems to achieve very high data transmission rates, significantly faster than standard Bluetooth technology. 4. Statement 4 is correct. Since VLC uses light waves instead of radio frequency waves, it does not cause or suffer from electromagnetic interference (EMI) with RF devices. This makes it suitable for use in EMI-sensitive environments. 5. Therefore, statements 1, 3, and 4 are correct.
