6. Market Trends in Microwave for Defense
7. Main microwave requirements for defense applications Reliability from a network that can withstand harsh environments Availability and network robustness Low latency for Network Enabled Capabilities Secure links and encryption Portable/compact solutions High power ODU Scalability and flexibility
8. Trends in defense Warfare is not network centric. It's commander centric. And that commander is enabled by networks. US General David Petraeus, Commander, U.S. Forces Afghanistan
9. Proliferation of deployable/semi mobile access networks
10. Secure and reliable telecommunication infrastructure Digital Microwave communication offers a reliable and secure transmission of sensitive information Reliable No physical media which could be affected by physical factors like ice, flood or street excavation. Secure The microwave signal in licensed frequency bands are very difficult to intercept Extremely narrow “beam” making interception difficult
11. Tactical Applications Rugged – with tailored enclosure Rapid field deployment using tripod direct mounting for the ODU and antenna Low power consumption (optional power backup) Light weight Designed to withstand extreme temperatures, vibrations, and more
12. Strategic Applications Defense Challenge: Build an army military grade long microwave backbone Connecting the Philippines islands with many over the water links with distances of up to 100km Cost-effective voice, data, and video conferencing services to satisfy command and control requirements Solutions 36 hops 1+1 all indoor 7 GHz Link Interface: STM-1 Why Ceragon?
