When it comes to mobile data, our smartphones are far more reliant on Wi-Fi. Given that’s the case, why are carriers so single-mindedly focused on acquiring new licensed spectrum and building expensive new 3G and 4G networks, when they could implement more Wi-Fi and tap into other sources of unlicensed spectrum? That’s the question a new study is asking.</div><div style="margin: 0px 0px 18px; padding: 0px; border:

Fulfilling these requests will lead to a substantial concentration in the ownership of the most valuable spectrum, risking both decreased competition and innovation. As part of a balanced approach to meeting the growing demands for data, policy makers should also enable more dynamic spectrum sharing and licence-exempt access across the spectrum. As shown in this report, licence-exemption promotes methods of broadband delivery that are overwhelmingly more efficient in their use of spectrum than their licensed counterparts. In addition, the licence-exempt ecosystem has been notable for creating contestable and
