Overview of the PTP 250
Overview of the PTP 250
This section introduces the key features, typical uses, product variants and components of
the PTP 250.
Purpose
Motorola PTP 250 products are designed for Ethernet bridging over point-to-point
microwave links in the unlicensed bands 5.4 GHz (ETSI Band B) and 5.8 GHz (ETSI Band C
and FCC ISM band). Users must ensure that the links comply with local operating
regulations.
The PTP 250 is used to create a transparent bridge between two segments of the
operator's network. This bridge can be treated as a virtual wired connection between two
points.
Key features
The key features of the PTP 250 include:
•
Orthogonal Frequency Division Multiplexing (OFDM) modulation and Multiple-Input
Multiple-Output (MIMO) techniques.
•
Wireless connections of up to 54 km (34 miles) in near line-of-sight conditions.
•
High link availability, through the use of adaptive modulation techniques that
dynamically reduce the data rate in severe or adverse conditions.
•
High-sensitivity antennas for improved signal recovery.
•
A built-in web server for advanced management capabilities including detailed radio
signal diagnosis.
•
Password control and encryption.
Benefit of the chosen bands
The products operate in bands that offer 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.
802.11n device
PTP250 uses 802.11n encoding and radio transmission. In areas where the PTP 250
co-exists with 802.11a and 802.11n devices, the PTP 250 detects the 802.11a and 802.11n
radio signals and chooses a clear channel away from any interference.
