Market Trends in Microwave for Defense

6


Main microwave requirements for defense applications

7

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


Trends in defense

8

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


Proliferation of deployable/semi mobile access networks

9


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

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


Strategic Applications

• 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?• High power split configuration 1+1• Integrated offering through a channel with

networking, terminal and support

Meeting the practical limits of physics

• Increasing modulation complexity meets natural limits

• From 256 to 1024 QAM, capacity increase is theoretical 25% (assuming no additional coding)

• System gain penalty about 7dB

• Requires “interference free” environment - can it work in field?
