Agenda Target Markets & Benefits New Version 2.300 Product Elements Products Features Product Elements Typical Applications

Target Markets The Airmux-400 series is targeting the global markets of Cellular Backhaul, WiMAX and ISP Backhaul, Broadband Access and Private and Government Networks All these markets require higher bandwidth (TDM & ETH) with longer range, robustness; while keeping the best price performance

Airmux-400 – Benefits High bandwidth with longer range – 50 Mbps full duplex net throughput reaching up to 120 km Combined Native TDM & Native Ethernet services on one platform Competitive prices – higher Ethernet & TDM capacity for lower prices Applicable to nLOS, over-water deployments and high capacity over extended range with improved robustness thanks to the OFDM, MIMO and antenna polarization features. Flexible product usage (& stock reduction) of the configurable ODU Fast and easy deployments via installation and alignments tools

Airmux-400 Version 2.3 New Features Hub Site Synchronization (HSS): Airmux-400 radios Airmux-200 radios Airmux-400 and Airmux-200 radios Monitored Hot Standby (1+1) – TDM services backup & Redundancy Diversity Feature Version 2.3 HSS V Monitored Hot Standby (MHS 1+1) Diversity Spectrum View

Hub Site Synchronization HSS between Airmux-400 radios Airmux-200 radios Airmux-400 and Airmux-200 radios HSS up to 16 radios in a site Fully supported by RAD Manager Supported by software upgrade to Airmux-400 install base All Airmux-400 radios in the field are HW ready for HSS

Monitored Hot Standby (MHS) 1+1 Providing redundancy and backup to TDM services Targeted for Cellular backhaul Providing protection against Equipment failure (ODU and IDU) Loss of air interface Using a primary link and a secondary link: Two Airmux-400 links A Airmux-400 link and a Airmux-200 link with new IDU-C Two Airmux-200 links with new IDU-C (single dual-pol antenna can be used)

Diversity Antenna diversity Capacity 25 Mbps MIMO Capacity 50 Mbps Antenna diversity Uses two antennas 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 – Receive Combining

Diversity Vs MIMO – When to Use? Use MIMO Mode to get the highest capacity, up to 50 Mbps full duplex Use MIMO when the air conditions are similar between the antennas Use Diversity instead of MIMO in the following cases: When the system cannot operate in MIMO Mode due to link conditions When you get higher capacity in Diversity Mode than in MIMO Mode Note that Diversity Mode requires understanding of the nature of interference and of the correct solution to deploy. Advise PS. Remember that the capacity in Diversity is ½ than that of MIMO

Spectrum View An RF survey tool Support link installation before service activation Activated by the installer Helps selecting the best channel during installation Supports quick and easy installation

Spectrum View – Display Information Spectral measurement for each of the 4 receivers that make the link Spectral power measurements in 5MHz channel granularity Current, average and maximum power per channel Channels free from radars, with radars and barred (for DFS bands) Scanned and un-scanned channels Channels selected for ACS Current operational channel Time stamp of the last spectrum scan Zoom, selective view of antennas and sites and detail level

Spectrum View – Tool Capabilities Save and restore – save the spectral information and also view retrieved spectral information from historical spectrum scans Diagnostics - the Spectrum View information is logged as part of the Diagnostics Information to improve link and system diagnostics and remote support. It can be retrieved from the RADWIN Manager menu with Help  Get Diagnostic Information Management Integration - Spectrum view information is supported in RADWIN’s MIB and can be used by external Network Management applications Designed for Unlicensed Spectrum – the spectrum measurement algorithms are designed to show accurate information while accommodating with variances in frequency, temperature and interference power and overcoming anomalies that tend to occur in high interference environments Scanning Time – ~10 seconds for an entire band scan. It is recommended to scan for a few minutes for accurate results.

Typical Applications

Targeted HSS Applications Access and Corporate Connectivity Where any links originate from a common hub site With HSS by Airmux-400 such applications now support high capacity connectivity Backhaul HSS is needed in installations where a Airmux-400 link is the backhaul for many lower capacity access links The backhaul link can be synchronized to the access links to mitigate potential mutual interference Attack Plan Identify existing customers with mixed network of Airmux-200 and Airmux-400 Propose the HSS solution for mixed deployment

Targeted MHS Applications Provide high reliability high-capacity Point-to-Point links Provide redundancy and high reliability for carrier class operators Optimized for high capacity links operating in license-free bands Additional values: Each link can use a different band for maximum protection to the air interface Affordable SLA can be offered by protecting part of the Airmux-400 trunks with Airmux-200 Go To Market Present the capability to Cellular Operators

MHS Spec Supported in Airmux-400 by software upgrade to the install base TDM service cut-over from the primary to the secondary link is completely automatic, less than 50 ms Automatic restore to primary link as soon as it becomes available Supports up to 16 TDM services for Airmux-400 and 4 TDM services for Airmux-200 HSS is used between the links Install both sites with HSS cables for additional protection Ethernet services No Ethernet 1+1 Ethernet traffic is always “on” on both links, while the TDM service is running only on one link Each link carries different Ethernet traffic
