6G: challenges and opportunities

The 6G Network: Terabit Applications It will extend the reality spatially and transform how we communicate with each other. Lower microsecond-level latencies could unlock real-time tactile applications such as almost zero-lag remote collaborative surgeries, real-time remote control of machines, and more .

Faster than 5G technology Operating at terahertz frequency bands, 6G will deliver a peak data rate of 1,000 gigabits/s having air latency less than 100 microseconds. When we talk about 5G vs 6G network speed, 6G speed is expected to be 100 times faster than 5G with enhanced reliability and wider network coverage.

Speed and latency will be the clearest distinction between 6G and 5G. This is what separates 5G and 4G in terms of performance, so we can also expect 6G to be magnitudes of times speedier than 5G. If early targets are eventually met, 6G networks will supposedly have 50-100x the capacity of 5G networks.

Processing power is major challenge in designing low power and low cost 6G devices. ➨6G uses visible light frequencies for part of its communications, hence drawbacks of VLC can be considered as drawbacks of 6G wireless technology. Visible light uses wavelength from 390-700 nm.
