Cloze Test – Test 25

In the following passage, there are blanks, each of which has been numbered. Find out the appropriate word/phrase in each case.

Light Fidelity (Li-Fi) is a bidirectional, high-speed and fully networked wireless communication technology -21 - to Wi-Fi. The term was coined by Harald Haas and is a form of visible light communication and a subset of optical wirreless communications (OWC) and could be a -22- to RF communication (Wi-Fi or cellular networks), or even a replacement in contexts of data broadcasting. It is wire and UV visible-light communication or infrared and near-ultraviolet instead of radio-frequency spectrum, part of optical wireless communications technology, -23- carries much more information and has been -24- as a solution -25- the RF-bandwidth limitations.
