that's actually called scintillation and does have a dramatic effect on performance. However, by installing them properly and with proper design, one can reduce the effects.
The main reason this system is better than RF is because it has much higher capacity... The fastest LMDS radios today can do 155 Mbps while this can do 10 Gbps. So there's an obvious advantage. Another advantage is licensing. microwave radios require licenses to operate, this does not. Those licenses have to be paid regularly too... and they are getting expensive.
they mention DWDM which stands for dense wavelength division multiplexing... in escence they are using many different eavelengths... and they are probably IR....
