Multiple Point to Point w/ HSS (Hub Site
Synchronization)

RADWIN 2000 can be deployed in
unique Multiple Point-to-Point
configuration

Dedicated bandwidth to as many as
16 dispersed sites

Hub Site Synchronization (HSS) unit
synchronizes transmission between
collocated radios
 Synchronizes Tx and Rx timing for all
units in hub site
 Eliminates collocation TDD
interference

HSS between
 RADWIN 2000 radios
 WinLink 1000 radios
 RADWIN 2000 and WinLink 1000
radios
HSS Applications

Access and Corporate Connectivity
 Where links originate from a common hub site
 RADWIN 2000 w/ HSS supports high capacity connectivity

Backhaul
 HSS is needed in installations where RADWIN 2000 is the
backhaul for lower capacity access links
 The backhaul link can be synchronized to the access links to
mitigate potential interference

Multi band radio

Multi band radio supports multiple frequencies on same
platform – ensures maximum transmission resiliency

Utmost field flexibility
Automatic Adaptive Rate

RADWIN 2000 changes air interface rate and modulation
dynamically, depending on radio link conditions

Benefits:
 Maximization of Ethernet throughput
 Enhanced robustness
 Better performance in interference
Automatic Channel Selection (ACS)

Automatic selection of “best-quality” channel for transmission

Enhanced robustness and higher performance
Automatic Repeat Request (ARQ)

Patented mechanism that ensures super-fast retransmission of
errant data

Repeat transmission is initiated without having to wait for a request
from the remote unit

The system minimizes either the latency or the error rate to
optimize performance for the type of services being delivered
Forward Error Correction (FEC)

FEC detects and corrects errors in the receiver

Ensures fast, robust and error-free communications
Jitter Buffer

By configuring the Jitter Buffer, the receiver jitter buffer for each
site can be enlarged, thereby increasing resistance to interference

Decreasing the Jitter Buffer decreases system delay

Jitter Buffer can be configured between 2.1 and 16.0 milliseconds
Spectrum Viewer

Spectrum Viewer is an RF survey tool that simplifies link planning
& installation by graphically displaying “cleanest” channel

The tool provides the following information:
 Spectral measurement of two antennas per site
 Spectral power measurements in 5MHz channel resolution
 Indication of radar-free channels (for DFS bands)
 Indication of bands selected for ACS
Spatial Multiplexing MIMO

MIMO = Multiple Input Multiple Output

A high rate signal is split into multiple lower rate streams and
each stream is transmitted from a different transmit antenna in
the same frequency channel.
Lower rate streams
Streams merged
into one signal
High rate signal
TX
RX
Diversity


Antenna diversity

Uses two antennas to improve the
quality and reliability of the link

Each antenna experiences a different
interference environment

The system chooses the best received
signal providing enhanced robustness
Antenna diversity requires antenna
separation, possible by two methods:

Polarization Diversity - combines a pair
of antennas with orthogonal
polarizations

Spatial Diversity - employs antennas
that are physically separated from one
another
Diversity vs. MIMO with RADWIN 2000

trunks with WinLink 1000
 Equipment failure
 Loss of air interface
Monitored Hot Standby 1+1 Architecture

Primary & Secondary links can
transmit on same or different
frequency channels

RADWIN 2000 & WinLink 1000
links can be used
interchangeably


secondary link:
 Two RADWIN 2000 links
 A RADWIN 2000 link and a
WinLink 1000 link with
new IDU-C
