Avoidable delay

India would have gained from an early 5G roll-out

America’s roll-out of 5G networks running on 3.7-3.8 GHz has led to a focus on aviation safety concern since this wavelength interferes with radio altimeter signals. Similar issues have not arisen with other 5G networks in the US, and elsewhere, since these operate on different wavelengths.
