Wireless point-to-point links are comparatively cheap, but require clear line of sight, uncontested spectrum and power. Sometimes you have none of those. Wireless also scales poorly past 1 Gbps. Fiber is more expensive up front, but cheaper in the long run if your bandwidth requirements grow. Fiber also does not become obsolete, like wireless equipment.
