Are there alternatives to microwave communications?
A requirement to avoid the harm caused by digital microwave radiation and ‘electrosmog’, is to either reduce EM field level or migrate to EM frequencies that are not harmful.
Two concepts present themselves:
- get nearer to every mobile device with the transmission/receiving antenna, and connect these with high capacity land lines (eg fibre optic)
- make local wireless links wherever possible non-microwave (eg infra red or visible light)
The Visible Light Communications Consortium has some ideas:
