The RADWIN Backhaul Advantage (cont.)

One Solution, One Link, One Platform

Robust & Reliable Operates in all environments & terrains Industry-leading MIMO, OFDM & Diversity technologies Field-proven air interface for optimal performance Monitored Hot Standby 1+1 Support – backup link ensures 24x7 service

continuity and revenue flow

Flexible Multi-band radio – one platform, multiple frequency bands Complies with international regulations Native TDM & Ethernet in one solution Seamless migration from TDM to IP Can be deployed in various topologies & configurations (PtP & Multiple Point-

to-Point)

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

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

Access and Corporate Connectivity Where links originate from a common hub site RADWIN 2000 w/ HSS supports high capacity connectivity

Dealing with Interference

Multi-band radio Automatic Adaptive Rate Automatic Channel Selection (ACS) Automatic Repeat Request Forward Error Correction Configurable Jitter Buffer Spectrum Viewer Directional Antennas MIMO OFDM based air-interface, enabling nLOS

deployments and achieves best spectral efficiency Spectrum Viewer

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.

Streams mergedinto one signal

TX

Lower rate streams

High rate signal

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

Monitored Hot Standby 1+1

Providing backup to TDM services in the event of: Equipment failure Loss of air interface

MHS 1+1 ensures high network availability & revenue flow Automatic switchover from the Primary link to the Secondary link in

less than 50 msec Automatic restore to primary link as soon as it becomes available Backup for up to 16 TDM services for RADWIN 2000 & 4 TDM services

for WinLink 1000 Affordable SLA can be offered by protecting part of the RADWIN 2000

trunks with WinLink 1000

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

Using a primary link and a secondary link: Two RADWIN 2000 links A RADWIN 2000 link and a

WinLink 1000 link with new IDU-C

Two WinLink 1000 links with new IDU-C (single dual-pole antenna can be used)

Simple architecture & easy installation

RADWIN Network Management System (RNMS)

Manage up to 10,000 RADWIN links from one location (NOC) Proactive real-time monitoring using performance graphs,

trend reports and threshold alarms Complete visibility & control over RADWIN-based network Interface to any SNMPc device Auto-discovery feature – discovers all RADWIN links in the
