Background - Principal Products

• Tactical radios– Interoperable Falcon® II,

software-defined tactical radios

– Falcon® III multiband, multimission, JTRS-compliant tactical radios

– HF, VHF, UHF, and multiband –manpack, vehicular, handheld, secure personal radios

• Cryptographic solutions– NSA-recognized leaders in embedded

encryption - Sierra,® Citadel,®

– Core differentiator and competitive barrier

– Communications security terminals


Multiband comms for the US Military

• Different communications use multiple frequencies & modes– Grd-Grd: Low band VHF-FM– Urban Comms: UHF-FM– Grd-Air: UHF-AM– Grd-SATCOM: UHF-Complex

Modulation

• Operational Drivers:– Special Forces– Multi-force operations– Has become the standard

• Warfighters needed an integrated solution - one radio, one battery

• Now moving toward a networked solution – basis behind Joint Tactical Radio Program (JTRS)

Which would you rather carry?

SDR Defined

The SDR Forum defines SDR as:"Radio in which some or all of the physical layer

functions are software defined”This does not imply a particular architecture.

Rather, it opens up the possibility to modify things like modulation and demodulation that were formerly immutable.

Software Defined Radio Evolution


LMR SDR General Benefits

• Flexible design (soft keys, user configuration)• Standard interfaces allows porting of features between products and

vendors• Reduced cost of product development

– Single software package for multiple hardware platforms. (Family of radios)

– Single hardware platform for multiple software applications. (FDMA now, TDMA in P25 Phase 2).

– Components can be tested individually based on where changes have been made.

• Reduced cost of upgrading communications.• Segmented architecture improves opportunities for code re-use.• Provide a pathway to future technologies such as cognitive radio.• Improved battery life and reduced heat emissions via software

control of radio components and CPU usage


Design Considerations

• Multiband means different things to different customers. – Some want to operate in one band or another. – Some need to be able to have multiple bands in one scan list.

• Key design choices include component granularity, allocation of performance requirements, data flows.

• Software solutions need to be monitored closely for latency and timing issues as the product evolves.

• Use of a comprehensive SDR architecture like SCA can introduce unnecessary software “baggage”. Select an architecture that appropriate for the product you are developing.


Lessons Learned

• SDR ≠ SCA. Don’t assume that you must use SCA to build a Software Defined Radio.

• Critical system timing (key performance parameters) must be benchmarked periodically during development as features are added.

• Interoperability is more than just software.Harris has decades of experience in developing multiband antennas and multiband transceivers for mission-critical applications.


The Magnitude of It All

• US Federal Government (non-DoD)– Approximately 100 agencies and 200,000 agents/officers– Primarily VHF-High and UHF-Low bands– Large areas of responsibility

• State and Local First Responders– Approximately 48,000 agencies and 2.5 million first responders– ~18,000 Law Enforcement Agencies, ~24,000 Fire Departments, ~6000

Rescue Squads– 757,907 FCC issued licenses to these agencies (per analysis by APCO

in 7/2006)FREQUENCY BAND PERCENTAGE USAGEVHF Low 30-50 MHz 10%VHF High 136-174 MHz 47%UHF Low 380-470 MHz 25%UHF High 470-512 MHz 5%700 MHz 764-806 MH ?800 MHz 806-869 MHz 13%
