The new thing in telecommunications is 5G wireless networks. Compared to 4G, 5G is capable of delivering much faster data transfers, much lower latency, more network capacity, etc. Actually, 5G is a grab-bag of multiple technologies. It can be used to create private Wi-Fi networks, and small cells can be used to create fast “mini-networks”. The extra speed and capacity means massive improvements in streaming video services as well as the possibility of entirely new services, involving virtual/ augmented reality, scaling up of IoT, machine-machine interactions, etc.
But 5G isn’t all that new. It’s been rolling out globally for over
