Q: Can I source and use my own PoE adaptor with the PTP 400 Series Bridge?
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.
Q: Who is Motorola?
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.
Q: Why has Motorola launched the PTP 400 Series Bridge?
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.
Q: What is Multiple-Input Multiple-Output (MIMO)?
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.
Q: What do you mean by “non-Line-of-sight”?
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.
