Management has decided to acquire a second building that is currently for sale and will relocate several departments to the new building so that approximately 50% of the employees are located in each building.

A direct line of sight exists between the buildings. You are the network administrator and must select a solution to allow the two buildings to be internetworked. What technology will you recommend to internetwork the two buildings?
