Some Terminology; What's New In Release 3.3.30 - Radwin 5000 HPMP User Manual

Some Terminology

Some Terminology
A Point to Multipoint network is typically abbreviated to PtMP. The PtMP networks
described in this Manual are of course, radio links.
A PtMP link consists of at least one high Base Station radio linked to several Subscriber
Unit radios. The SUs are sometimes called Customer Premises Equipment (CPEs). The
terminology comes from the field of telephony.
The RADWIN 5000 HPMP product suite supports considerably higher capacity than other cur-
rent technologies (such as Wi-Max). We distinguish between generic BSs and SUs and RAD-
WIN units, relabeling the latter, HBSs and HSUs (H = high capacity).
The radio links are effected by using a sector antenna with the HBS. The HSUs use direc-
tional antennas aligned to the HBS.
A Sector consists of a HBS and a group of HSUs within the angular sector covered by the
HBS antenna. A Sector is typically 60°, 90° or 120° depending of course on the choice of
antenna.
HBSs may be collocated to provide sectorial coverage up to 360°.
The RF characteristics of a Sector will be common to each radio: Frequency (regulation),
band and channel bandwidth. Adjacent Sectors in a PtMP network will typically use different
frequencies and non-overlapping bands to mitigate HBS self interference.
A HSU may be defined as fixed, nomadic or mobile.
A fixed HSU is just that - installed at a fixed location.
A nomadic HSU is attached to a vehicle that moves about within a sector and across sectors
inside a well defined area. Service is provided when the vehicle is stationary.
A mobile HSU (HMU) provides service while the vehicle to which it is attached is moving or
stationary. The vehicle is typically a railway carriage, a car (automobile) or a ship.

What's New in Release 3.3.30

Release 3.3.30 is a LA release, which in addition to many hardware improvements, has three
completely new features:
• Increased capacity to 250Mbps
• Small form factor HBS of 25Mbps with integrated antenna
• Enhanced robustness by Adaptive Interference Sensitivity
• Split Sector ID to differentiate between fixed and Mobility/Nomadic HSUs
• A single HSU may be assigned up to 63 time slots.
