GSA ITU Article: Global opportunities for 5G terrestrial communications.
This GSA ITU article is featured in the ITU News Magazine No. 4 2019 and considers the broad range of opportunities 5G brings to the global market providing key considerations are met.
The key message is that spectrum must be utilised in the most efficient and cost effective way, and spectrum availability must not impact the commercial requirements of the broader mobile ecosystem.
For this growth and adoption of 5G to happen three initiatives need to align:
The mobile ecosystem of global suppliers has to forward invest in 5G networks.
This is already happening with infrastructure, chip and device manufacturers accelerating the availability of 5G software and hardware, while also making economic strides in reducing the costs of deployment and management of 5G technology.
The availability of 5G spectrum needs to be accelerated.
5G will require spectrum in the low bands (below 2 GHz), mid bands (2 GHz to around 6 GHz) and high bands (above 6 GHz) to achieve the full IMT‑2020 vision of mobile broadband for the mass-market, including serving rural areas that have not always benefited from mobile communications.
5G must reach in-building.
The quality of 3G or 4G coverage in buildings needs to improve, and is a major headache for enterprises, which will only increase in severity, since modern buildings are built to reflect radio waves. This restriction can be turned into an advantage by using the high bands in-building in addition to outdoor.
GSA fully expects that, with the right industry focus, 5G technology will be deployed faster than previous technology generations. According to Ovum data, 3G took 10 years to reach 1 billion subscriptions; by comparison 4G took less than six years. GSA expects 5G to take less than five years to reach 1 billion subscriptions.
