I feel like licensing is even less pragmatic than technological capability and limitation. Ubiquiti's 2.4ghz and 5ghz 'air fiber' radios are approved for use in India, license free, and those spectrums are license free under certain requirements. There is no difference between laser and microwave devices for in this use case, except that laser has higher speed but lower persistence in line of site. https://community.ubnt.com/t5/airFiber/Airfiber-in-India/m-p...

EDIT: maybe a missing detail is that “AirFiber” and similar products are point to point comm devices. So each pair of AirFiber units is a 1.2+ gbps link, same as a laser set up. You may be confusing with an alternate PtMP radio setup.
