Hi All,
I'd like your good answers about this topic.
In fact, i'm not asking only about the 60 GHz band, but generally the "tens of gigahertz" bands.
1. I know that cellular service providers use microwave links @ ~30 GHz to transmit data with high capacity. Why can't they use their own GSM/WCDMA/etc. frequency bands for the same purpose?
2. Given that they have a physically larger bandwidth at those microwave bands, what is their transmission modulation? Is it different than the one they use for regular broadcast?
Thanks and have a good week,
P.
