21 FAQs
Can I source and use my own PoE adaptor with the 600 Series bridge? No. The 600
Series bridge 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.
Who is Motorola, Inc.? 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.
Why has Motorola launched the 600 Series bridge? The 600 Series bridge is the first
product in this band 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 600 Series bridge 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, i.e., 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 600 Series bridge ? There are many special features built-
in to the hardware of the 600 Series bridge. The product offers the highest system gain in its
class through high sensitivity antennas for improved signal recovery. It also features a
Software Defined 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 600 Series bridge has a built-in web server for advanced management
capabilities including detailed radio signal diagnosis.
In which frequency bands does the 600 Series bridge operate? The Motorola point-to-
point 600 Series bridge operates in the unlicensed 5.4 GHz (ETSI Band B) and 5.8 GHz
(ETSI Band C and FCC ISM band). This means no license is required to operate the 600
Series bridge.
