TIA surveys operators on 5G future

5G cellular is predicted to touch everything in its attempt to extend 4G-LTE and deliver new use cases. This generation of wireless technology, expected to roll out in 2020, will require great effort from network operators and is set to launch in Asia.

The Telecommunications Industry Association (TIA) surveyed 58 operators globally on the future of 5G. "To bring a new generation of wireless technology to the mainstream is a colossal undertaking that requires R&D collaboration, spectrum, and a business case," TIA wrote in an 18-page white paper.

Use case development is a significant issue for the industry performance requirements and the business models unfold, the survey found. Seventy-six per cent of respondents said better broadband performance would push 5G and 74 per cent counted the Internet of Things as a primary driver. More specific use cases such as tactile Internet and virtual reality "scored respectably, but ranked lower overall."

Ninety-one per cent of operators surveyed said system performance will be primarily driven by higher density networks built using small cells; 55 per cent of respondents thought massive multiple-input multiple-output (MIMO) would have a great effect on performance.

"Massive MIMO may imply the use higher band spectrum with wider channel widths, but it can be applied in lower-band scenarios," the survey stated. "Device-to-device, in third place, raises the question of proximity services being more important in 5G and of greater use of ad hoc and mesh networks. This could potentially be useful, for example, in vehicle-to-vehicle, public safety and general consumer applications."

Asia leads in 5G race

Seventy-one per cent of operators surveyed expect Asia to lead 5G development and deployment, while North America and Europe drew 52 per cent and 45 per cent of respondents. These thoughts were largely based on geography, with operators largely believing their home country would be first.

Japan's DoCoMo plans to launch a first release of 5G at the 2020 Summer Olympics in Tokyo, and has developed a multi-layer architecture phantom cell that would allow small cells to be overlaid on macro cells. In Korea, leading operators such as SK Telecom plan to demonstrate prototype 5G systems at the 2018 Winter Olympics.
