Can I source and use my own PoE adaptor with the PTP 300 Series bridge? No. The
PTP 300 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.
What is Multiple-Input Multiple-Output (MIMO)? The PTP 300 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, 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 300 Series bridge ? There are many special features
built-in to the hardware of the PTP 300 Series bridge. 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 300 Series bridge has a built-in web server for advanced management
capabilities including detailed radio signal diagnosis.
In which frequency bands does the PTP 300 Series bridge operate? The Motorola PTP
300 Series bridge operates in the unlicensed bands 5.4 GHz (ETSI Band B) and 5.8 GHz
(ETSI Band C and FCC ISM band). This means that no license is required to operate the PTP
300 Series bridge.
Why does the PTP 300 Series bridge operate in the 5 GHz 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.
