The 5G standard utilises radio bands from sub GHz to 40 GHz. In rural environments where cell towers are few and far between narrowband IoT (NB-IoT), sub GHz spectrum will certainly provide improved coverage, but this comes at the cost of speed and latency. Superfast connection speeds will be realised at higher frequencies (25-40 GHz), but at the cost of range. Users will need to be within a mile of the cell tower and urban objects – such as buildings, vehicles, trees – are likely to have decremental effects to the signal strength.
5G licensed spectra suppress the potential interference that may occur within the unlicensed Wi-Fi spectra, which are shared by many other wireless technologies like Bluetooth and microwave ovens. 5G will be supplied by cellular wireless carriers but can be built as a private network by deploying your own access points, just like with Wi-Fi.
The high GHz band architecture for 5G requires more radio access points. Users for indoor space will need to assess the infrastructure – possibly deploying indoor microcells, repeaters and distributed antennas – to solve indoor 5G service issues.
5G is aimed for truly mobile connectivity such as:
Public transport and safety vehicles
External environments e.g. mining, oil and gas extraction, farming, some manufacturing and campus or leisure areas
5G offers advantages in the IoT market (NB-IoT, LPWAN) and as the 5G standards mature, the technology will improve its options for low-power IoT connectivity. Over the coming years, the 5G roll-out will start in mainstream cities and specific geographic locations; 4G technology will remain prevalent for several years. Users will need new devices, dongles, and routers to connect to 5G services, and IoT devices will need specific cellular compatibility to connect to 5G.
