(Telecompaper) Releasing ultra-short-wave mobile spectrum could add USD 565 billion to global GDP and USD 152 billion in tax revenue from 2020 to 2034, according to a study conducted by TMG for mobile industry association GSMA. The move would also improve access to healthcare, education and mobility whilst reducing pollution and increasing safety, said the report, adding that such outcomes rely on government support for the identification of sufficient millimetre wave (mmWave) spectrum for the mobile industry at the next ITU World Radiocommunication Conference in 2019 (WRC-19).
