On the opening day of CommunicAsia DSA President Kalpak Gude highlighted the challenges and barriers that need to be overcome if the potential of 5G is to be fully realised.
The event reflects the converging areas of Technology, Media and Telecommunications and will see more than 900 product launches, 1,800 exhibitors from 52 countries/regions and 40 group pavilions. ConnecTechAsia will cover a holistic view of infrastructure, innovation, services, and thought-leadership, enabling businesses and governments in Asia to navigate and adapt to this new era of digital convergence.
The advent of 5G is one of the technology innovations which will accelerate the path towards digital convergence, but telecom operators will have to work together with technology and infrastructure providers in order to ensure efficient implementation of 5G explained Gude.
As the path towards 5G begins to gain momentum, the Dynamic Spectrum Alliance has today set out its vision for a 5G future and the opportunities and challenges that will arise from deploying it.
“5G is widely expected to incorporate a number of innovative features, all of which will allow a large range of applications with diverse requirements to be supported,” said Gude. “Despite the benefits of 5G, there are still several barriers to overcome. The DSA believes that dynamic spectrum sharing can contribute to alleviating many of the key barriers to deployment that currently exist.”
Deploying 5G needs to involve more than just mobile carriers if it is to be successful, Gude continued. The mobile industry cost estimates for deploying 5G networks are more than several hundred billion dollars, just for Europe alone. These costs are above and beyond the cost of continuing to deploy and maintain the 4G networks that will continue to carry most existing mobile services. This means, said Gude, that the carriers alone cannot be expected to carry the CapEx burden alone.
“Spectrum bands considered for 5G applications are above 3 GHz and spectrum in those bands have significantly poorer distance propagation and building penetration,” he continued. “As a result, exclusive licensing for this type of spectrum is inherently wasteful because it will leave spectrum underutilized by design. The DSA therefore believes sharing, particularly dynamic sharing, is a much more effective way to manage this spectrum than the exclusive licensing paradigm where the license gives the owner the right to both use and exclude. Dynamic sharing enables both licensed and lightly licensed use in the same bands, providing opportunities to more entities to deploy infrastructure.”
