In terms of technology, 5G uses radio waves for sending and receiving data while Fiber optic communication uses light to transmit data through fiber optic cables. Whereas 5G can have downlink speed up to the scale of 20 Gbps and 10 Gbps uplink, practical speed measured on Fiber cables is 100 Gbps. Related- 5G vs 4G.

Therefore, unlocking the visible light spectrum and deploying indoor/outdoor optical wireless systems would be a necessity for the next generation communication technologies in order to alleviate the spectrum crunch .
Read moreHow does 5G communicate?
All 5G wireless devices in a cell are connected to the Internet and telephone network by radio waves through a local antenna in the cell . The main advantage of the new networks is that they will have greater bandwidth, giving higher download speeds, eventually up to 10 gigabits per second (Gbit/s).
Read moreHow does 5G wireless work?
A: 5G is based on OFDM (Orthogonal frequency-division multiplexing), a method of modulating a digital signal across several different channels to reduce interference . 5G uses 5G NR air interface alongside OFDM principles. 5G also uses wider bandwidth technologies such as sub-6 GHz and mmWave.
Read moreHow do devices connect to 5G?
To use the 5GHz, your WiFi router must have dual-band WiFi support . It Should support IEEE 802.11 b/g/n/ac or WiFi 4 and WiFi 5 on 2.4GHz and 5GHz bands. Dual-band routers have the option of setting the same SSID/WiFi name for both 2.4GHz and 5GHz bands. D-Link calls this “smart connect“.
