not really, fiber is still greatly preferred (For example: it&#x27;s impossible to do 40Gb by microwave&#x2F;millimeter wave, but a CWDM 4-channel 4x10GbE passive mux&#x2F;demux on two strands of singlemode is trivial and very very cheap), or just a pair of 40Gb QSFP 10km reach optics using a single 1550nm wavelength between two routers or metro-E switches. But wireless can reach small cells, rooftops and towers that might be a very costly underground fiber build at $400-900&#x2F;meter total construction cost to dig up streets in urban cores. It very much depends on the location.
