Bluwan warns that using millimetre wave frequencies in 5G access networks will drain device batteries, but says 'the right people' are working on the problem.
There has been much talk of 5G access technologies at Mobile World Congress this week, including the use of millimetre wave (MMW) in high spectrum bands, but one company warns that there are still major challenges to be overcome, particularly when it comes to devices.
"We have to be very cautious," Shayan Sanyal, chief marketing officer at wireless transmission technology company Bluwan, told Total Telecom on Wednesday.
Using 6 GHz-plus MMW spectrum for transmission works; many challenges have been overcome and the technology is fairly advanced, Sanyal explained. But there is still a lot of work to do on devices.
The need for advanced antenna processing inside the device requires a lot of power. "[That will] wipe your battery dry," Sanyal said.
"The science is here," but it remains to be seen if it is cost-effective and deployable, he said, particularly given that most industry players are predicting that 5G will come to market as early as 2020.
