No. The PTP 400 Series Bridge uses a non-standard PoE configuration. Failure to use the 

Motorola supplied Power Indoor Unit (PIDU Plus – PTP 400 Series) could result in equipment 

damage and will invalidate the safety certification and may cause a safety hazard.  

Motorola, Inc. is a specialist wireless manufacturer with a high quality engineering team that 

is developing advanced radio solutions that allows high capacity building-to-building bridges 

to be established even in deep non-Line-of-Sight conditions.  

The PTP 400 Series Bridge is the first product in this band to feature Multiple-Input Multiple-

Output (MIMO). The PTP 400 Series solutions allow wireless connections of up to 200km 

(124 miles) in near line-of-sight conditions and up to 10km (6 miles) in deep non-line-of-sight 

conditions. 

The PTP 400 Series Bridge radiates multiple beams from the antenna - which significantly 

protects against fading and radically increases the probability that the receiver will decode a 

usable signal. When the effects of MIMO are combined with those of OFDM techniques and a 

best-in-class link budget, there is a significant improvement to the probability of a robust 

connection over a non-line-of-sight path. 

This term refers to a wireless connection between two points without optical line-of-sight. i.e. 

with obstructions in between the antennas but the transmitted signal is still able to reach the 

receiver and produce a good quality link.
