A cascaded line-of-sight wireless communications system operating in free-space. The system provides broadband access for subscribers, allowing high speed wireless data communication across cities or towns. The system has a free-space optical network that includes at least two optical repeater block devices for receiving, amplifying, and re-transmitting optical signals, and a gateway device coupled to one of the optical repeater block devices. The system is modularly constructed in a cascaded manner to efficiently and wirelessly relay data signals across the system. Particularly, the broadband access is unaffected even in the presence of natural or men-made impediments.
