  1. BreezeNET DS 11Version 4 For Bridging & Backhauling and Point-to-Multipoint Oct 2003

  2. Backhaul What is the DS 11? • A PTP and PTMP bridging system • Complies with 802.11b • Outdoor unlicensed radio in 2.4GHz • Data rate 11 Mbps • Ideal for: • PTP backhauling and bridging • PTMP bridging applications

  3. #1 ... to be DS 11 Main Advantages • Robust Outdoor Bridge • Cost effective • Range of up to 60 Km (37 miles) • Net throughput of more than 6Mbps • Multi layer security package • PTP and PTMP • Easy installation • IEEE 802.11b and 802.3 BU 310 Km Guinness World Record World’s longest Wi-Fi connection using the DS11 Outdoor Bridge

  4. 11 Mbps, 802.11b 60 Km DS 11 Performance • Range: • 10 Km distance under ETSI requirements • 25 Km (15 Miles ) distance under FCC • Longer distances achievable in unregulated domains • Official maximum 60 Km (37miles) PTP link tested at full performance • Data Rate: • Adaptive 11, 5.5, 2 and 1Mbps • Fairness and Performance Maximization in PTMP (Special configurable parameters) • Environment: • Temp: -40C to +55C • Humidity: 5 – 95% (non-condensing)

  9. New Features in the DS 11 Ver 4

  10. What is the BreezeNET DS 11 ver 4 • A new generation of the existing DS 11 Ver 3 • Includes both hardware and software changes Main areas of improvement in Ver 4 (compared to Ver 3): • Security • Performance • Ease of installation and Maintenance

  11. Router BU RBs Ver 4 – Added Security Features • MAC Address Association Control (BU feature) • A list of MAC addresses in the BU that are allowed to be associated with it (Default: all) • WEP Key Length of 64 or 128 (both for BU and RB) • 128 bit key allows for better security • 64 bit key allows communication with remotes that have 64 bits WEP only (Default: 64) • Unicast Relaying and Broadcast Relaying (BU only) • Control of Broadcast and Unicast relaying • When enabled, the BU will transmit back into the sector messages from RBs in the sector that are destined to RBs in the same sector (default: Enable). • ESSID “ANY” option control (BU feature) • A BU feature to allow/Disallow association with units that use “ANY” for the ESSID (Default: disable) • Proprietary scrambling of data (both for BU and RB) • Extra security measure, proprietary to DS11 (Default: disable) • Independent of the WEP

  13. Ver 4 – Performance Enhancing Features • Preamble length (both for BU and RB) • Selection between “Long” or “Short” Preamble • Increase throughput in “Short Preamble” • Use it always unless you must support “Long Preamble only” units (Default: Long) • “Best BU” and “Preferred BU” (RB feature) • Best BU: scan the area and choose the BU with the best RSSI (Default: enable) • Preferred BU: associate only with the BU that is marked as the preferred one (Default: None). Maximum net data rate of the DS 11 Ver 4 is 6.2 Mbps

  14. Ver 4 – Performance Enhancement (cont.) • Automatic dissociation of RB (BU feature) • While BU is disconnected from the Ethernet dissociate all RBs and do not associate any RB • Used to obtain BU redundancy • Ethernet Backoff Control (both for BU and RB) • On detecting a collision a station will wait a locally determined period of time before attempting re-transmission • The “disable” option is useful in PTP to increase Ethernet efficiency due to low collision probability - no need to wait after collision (Default: Disable) • Reject/Forward Unknown (both for BU and RB) • Reject /Forward frames whose destination addresses are not recognized by the bridge – More efficient Air interface (Default: Forward) RB1 BU2 RB2 x RB3 BU1 RB4 BU RB Detecting Collisions?

  15. Ver 4 – Easy Installation and Maintenance • Automatic Configuration Single Button Configuration of Common Modes: • PTP Mode CW=15, RTS threshold=2437 • PTMP Mode CW=63, RTS threshold=2437 in BU and 60 in RB • Compatibility mode Rate=2Mbps, Short Preamble=disable, Scrambling=disable • High Performance Mode Rate=11Mbps, Short Preamble=Enable (in BU only)

  16. Ver 1 Ver 2 Easy Software Upgrade • One click upgrade of multiple units firmware • Always keeps (last) SW version in flash memory • Automatic fallback to previous version when required • Progress indicator bar • Acknowledgment from every unit • Flash Memory contains two last versions (both for BU and RB). Current and last versions are kept in memory allowing regression to previous version.

  17. Ease of Installation and Management Installation • Easily manageable CAT-5 Input/Output cable • 110/220 universal power supply • RSSI Led Bar for antenna alignment • Extensive LED diagnostics in both indoor and outdoor units • “Back to Factory Default” Reset button Management • User friendly Configuration Utility • Remote management using SNMP • A range of counters for diagnostics • Per link statistics in the BU

  18. Compatibility • Backward compatibility • The DS 11 Ver 4 units are backward compatible with the Ver 3 product • When Ver 3 and Ver 4 units are mixed in one location only Ver 3 features are supported • Upgrade ability • DS 11 Ver 4 includes hardware changes and therefore a Software Upgrade is not applicable Ver 4 Backward Compatible ….. Ver 3

  19. DS 11 Ver 4 – Product Variation The following variations were prepared:

  20. Conclusion

  21. The Renewed BreezeNET (PTP) Family A family of PTP solutions Legacy, PTMP and others

  22. Competitive Advantage • A true Outdoor Unit The DS 11 is one of the only TRUE outdoor unit in the market • Range The DS11 leverages on its outdoor capabilities to extend to longer ranges (up to 60 Km) • Power Configurable from –4 to 24 dBm, the unit’s power can be optimized for high performance with minimal spurious emissions

  23. Summary • Cost Effective • Robust Outdoor Solution • PTP and PTMP • Long Range • High Throughput • Enhanced Security Package • Easy to Install and Maintain • Advanced User Friendly Configuration Utility • Alvarion World Wide Presence and Support
