  3. RADWIN 2000 – General Overview (cont.) • Advanced Air Interface – optimal performance in sub-6GHz bands through use of MIMO, OFDM & Diversity technologies together with RADWIN’s proprietary air interface • Multi-band Radio – increased field flexibility and reduced operational costs • 2.4 GHz & 4.8 – 6.1 GHz over single platform • Superior Spectral Efficiency at 20MHz channel - enabling high capacity services in crowded spectrum and significant spectrum savings • High Tx Power of 26 dBm - high performance with smaller antennas

  4. Total Net Throughput (Full-Duplex) 4

  5. TDM Performance Typical performance at 5.8GHz with99.99% availability 5

  6. RADWIN 2000 Applications Cellular & IP Backhaul High Capacity Private Networks Access for Large Corporations & Institutions 6

  7. Access for Large Corporations RADWIN offers a Corporate Connectivity Portfolio for organizations of any size WinLink 1000 Access – for small enterprises WinLink 1000 – for medium-large enterprises RADWIN 2000 – large to very large enterprises, up to 16 E1s/50 Mbps per customer! 7

  8. High Capacity for Private Networks RADWIN 2000 – the solution for High-Capacity Private Networks Large corporations Campuses, health organizations and data-intensive public institutions 8

  9. Backhaul with RADWIN 2000 The ultimate high-capacity backhaul solution Providing backhaul for any access solution: WiFi, Point-to-Multiple-Point, Multiple Point-to-Point, etc. RADWIN 2000High-Capacity Backhaul Access Hub 9

  10. Cellular Backhaul

  11. The RADWIN Backhaul Advantage High-Capacity Wireless Sub-6GHz Solution • Low CAPEX • Very competitive price • Low OPEX • Easy to install and maintain (1 person, 1 hour) • Fewer towers, fewer links • Instantly Deployable – Immediate Revenue • License free – no license fees, no trenching

  12. 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)

  13. 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

  14. 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

  15. 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

  16. Multi band radio • Multi band radio supports multiple frequencies on same platform – ensures maximum transmission resiliency • Utmost field flexibility

  17. 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

  18. Automatic Channel Selection (ACS) • Automatic selection of “best-quality” channel for transmission • Enhanced robustness and higher performance

  19. 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

  20. Forward Error Correction (FEC) • FEC detects and corrects errors in the receiver • Ensures fast, robust and error-free communications

  21. 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

  22. 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

  23. 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

  24. 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

  25. Diversity vs. MIMO with RADWIN 2000 Diversity Capacity 25 Mbps MIMO Capacity 50 Mbps

  26. 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

  27. 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

  28. 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 network automatically, within minutes • Available in Enterprise & Platinum packages

  29. RADWIN 2000 Roadmap
