Despite growing buzz around 5G, there are still significant questions that need answers before the technology is rolled out.
"Not least, the question of who will pay for the infrastructure to deploy it," said Hayduk. "What's more, we don't even have complete 4G coverage yet, even in big cities where signal can be patchy."
In Asia Pacific, the lack of basic mobile broadband coverage, geographical differences, and unavailability of significant funding are challenges that need to tackled before rolling out 5G, according to Huawei. But there's a silver lining, said the spokesperson: the lack of legacy systems provide an opportunity for countries to leapfrog their progress to 5G.
"National (information and communication technology) plans are crucial," the spokesperson added.
Before companies can roll out services, regulators also need to work quickly on allocation of frequency space for 5G, according to Ewerbring.
He said, "Our big encouragement to every regulatory body is to work ... on releasing 5G spectrum and large amounts of it. Any country that, for whatever reason, is not able to do so, runs the risk of setting back the local community because 5G cannot be launched."
The Ericsson report noted that the speed of 5G network deployment will depend on the growth of the complete ecosystem, including the availability of 5G-enabled devices and decisions on spectrum allocation.
"It is expected that many operators will deploy 5G commercially from 2020, in line with the time plan for 5G standardization," the report added.
