The PTP 600 Series Bridge will operate at ranges from 100 m (330 ft) to 200 km (124 miles), 

within 3 modes: 0-40km (0-25 miles), 0-100km (0-62 miles) and 0-200km (0-124 miles). 

Operation of the system will depend on obstacles in the path between the units. Operation at 

40 km (25 miles) or above will require a near line-of-sight path. Operation at 100m (330 ft) 

could be achieved with one unit totally obscured from the other unit, but with the penalty of 

transmitting at higher power in a non-optimal direction, thereby increasing interference in the 

band. This subject is covered in more detail in section 6.1.3 “Path Loss Considerations“.
