We’ve seen tremendous progress in DSL and microwave technology for high-bandwidth transmission. Both domains achieved high speeds by leveraging very advanced modulation technologies and by utilizing more spectrum and higher frequencies. Today, Gbit/s transmission over copper cable is possible by using a broad 200MHz spectrum in combination with vectoring and a very advanced modulation scheme. Similarly, microwave radio systems utilizing 2.5GHz spectral width in the E-band can even achieve 10Gbit/s bandwidth, albeit at a significantly higher price point ...
