General FAQs
Can I source and use my own PoE adaptor with the PTP 600 Series? No. The
PTP 600 Series uses a non-standard PoE configuration. Failure to use the Motorola
supplied Power Indoor Unit could result in equipment damage and will invalidate the
safety certification and may cause a safety hazard.
Why has Motorola launched the PTP 600 Series? The PTP 600 Series is the first
product to feature Multiple-Input Multiple-Output (MIMO). The PTP 600 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.
What is Multiple-Input Multiple-Output (MIMO)? The PTP 600 Series radiates
multiple beams from the antenna - the effect of which is to significantly protect against
fading and to radically increase 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.
What do you mean by “non-line-of-sight”? A wireless connection between two
points without optical line-of-sight, that is, with obstructions between the antennas the
transmitted signal is still able to reach the receiver and produce a good quality link.
What else is special about the PTP 600 Series ? There are many special features
built-in to the hardware of the PTP 600 Series. The product offers the highest system
gain in its class through high sensitivity antennas for improved signal recovery. It also
features a radio system that operates on ultra fast digital signal processors but is
controlled by firmware giving the ability to download new firmware when
enhancements become available. The PTP 600 Series has a built-in web server for
advanced management capabilities including detailed radio signal diagnosis.
In which frequency bands does the PTP 600 Series operate? The Motorola point-
to-point 600 Series operates in the licensed bands 2.5 GHz, 4.5 GHz, 4.8 GHz and 4.9
GHz, and in the unlicensed bands 5.4 GHz (ETSI Band B), 5.8 GHz (ETSI Band C and
FCC ISM band) and 5.9 GHz. Users must ensure that the PTP 600 Series complies with
local operating regulations.
Why does the PTP 600 Series operate in the 5GHz band? The 5 GHz band offers
the dual benefits of high data throughput and good radio propagation characteristics.
The wide band of spectrum available is subdivided into several channels such that
multiple systems can operate in the vicinity without causing interference to one
another.
