Expect to Find Some Thorns in 5G's Bed of Roses
www.eetimes.com, Sept. 19, 2022 –
As new technologies are introduced to society to solve existing problems, new problems are often brought along. That, of course, creates the need for additional developments. For example, the introduction of cars had a massive impact on personal transport and delivery of goods but presented issues with road safety, road infrastructure, and air quality challenges.
The same can be said for many modern technologies. Cloud computing has seen a need for lower latencies, internet-of-things devices have created a world constantly under threat, and Industry 4.0 has demonstrated that existing industrial networks are simply not up to standard.
One problem that these internet-related technologies have in common is the need for a common network technology that can reduce device latency, support more devices, and provide new software capabilities not currently seen in existing network technologies.
When looking at current network options, engineers find themselves having to compromise to some degree, no matter what technology they choose. Wi-Fi is cheap and easy to implement but has a limited range and can't handle large numbers of devices on any one network. It also has high latencies, while private 4G networks have been primarily aimed at smartphones and thus aren't entirely suitable for IoT devices. LoRa provides excellent range but at a cost of extremely low bandwidth, and current local-area-network options are either unsuitable for real-time tasks or use proprietary solutions that struggle to work with other networks.
5G TOUTED AS FUTURE-PROOF
One network technology that continues to gain traction is 5G. It seems to be the network solution that will solve everything with its obscenely high download speeds, lightning-fast connection times, low latency, and support for numerous future technologies. But what makes 5G so capable compared with previous technologies?
