Public Safety Mobile Computing Trends and
Opportunities
Status of Mobile Computing
Current applications– Simple query/response– Messaging based– On-board Applications– Limited field reporting deployment
Constraints– Limited bandwidth– Difficult and costly interfaces
Changing the face of mobile technology
The effect of re-farming the spectrum– 700 MHz channel allocations– Introduction of the 4.9GHz channels
New Technology– Mesh Networks– Wi-Max
The Nextel conversion=Removing the bandwidth barrier
The Challenge:
Can wireless broadband work here?
Wireless Broadband Access
Previously: Public broadband access
(Wi-fi) available at hot spots
Public 802.11b systems have very limited range, often insecure
No mobility or automated roaming between hot spots
Coming: 802.11e (Wi-Max) with 2-
30 mile range Mesh Technology
802.11a/b/g
Improving Wireless Broadband for Public Safety
Commercial wireless LANUnlicensed 2.4 / 5GHz frequencies
Mesh Technology
Self-healing ad-hoc and mesh networks
Coverage and capacity expansion to meet demand
4.9 licensed Public Safety
Higher Availability and Reliability
Licensed 4.9 GHz frequenciesImproved range and security
Motorola has expanded the capabilities of 802.11 with Mesh technology to meet the mission critical needs of public safety users
MESH Technology
Spectrum ConsiderationsWhy 4.9GHz spectrum?
Advantages of 4.9 GHz?
FCC Licensed Spectrum Dedicated to Public Safety, so interference is known and controlled
Dedicated/Organized band avoids channel interference, which will increase throughput
Lower adjacent channel interference due to tighter emissions mask at higher power (anything > 100mW)
Excellent Complement to Wide Area Data System
50MHz of Spectrum per jurisdictional area
Spectrum Considerations - 4.9GHz Details
How can it be used ?– Mobile connectivity – Point to multipoint – Point to point (Requires special license)
What rules govern coverage area of this frequency ? – Granted on a jurisdictional basis for full 50MHz– FCC has not implemented specific rules for protected
area by PS agencies– Local RPC (Regional Planning Committee) will create
general guidelines for use • RPC can only influence use• RPC can not govern use• Disputes of use fall to individual agencies that are in
dispute

Applications
With the appropriate system design MeshNetworks technology will enable the use of these data applications
When broadband is a reality
Moving from 19.2 Kbps to 1-3 MbpsNo more constraints on how much
data can be delivered over wireless networks
The SafeCom vision– www.safecomprogram.gov Statement of
RequirementsWide-band infrastructure support
Emerging standards
Interoperability standards for data– Global Justice XML Data Model– Emerging emergency management
protocols– Web services, SOAP, and SOA
Networking and technical standards– TCP/IP, XML, SAML
National program standards– National Intelligence Plan– CAD/RMS Functional standards
Mobile Computing
Law Enforcement FunctionsThe future is now
Basic messaging capability
Instant messaging– Unit to unit (Internal and External)– Unit to dispatch– Group call– Supervisor to squad
E-MailVoice over IP
Inquiry and response—external databases
Queries on people, vehicles, guns, property to state justice/DMV and NCIC data bases
Queries to local or county RMS or warrant repositories
Queries to local or county, or commercial supporting systems—permits, hazmat, tax, finance, personnel
Queries to licensing and registration systems.
De-conflictionSupport for NCIC 2000 concepts
Knowledge Management
Localized data on contacts, businesses, resources, schools, universities, military installations
Crime mapping and analysisPremise information including hazardsSupport for problem oriented policingFloor PlansPolicy and Procedures, Legal and other
reference material
CAD Interaction Receive call information and updates Send acknowledgement and status changes Post call information into reports Handle external data base queries (may not go
through CAD) Submit call status change and closure Access to CFS history Resource Scheduling and Calendar Electronic Roll-Call GIS Real-Time Mapping Display Field Dispatching Capability Voice Activated Commands
Information Acquisition
Preparation and submission of incident, accident, citation, preliminary arrest and other reports
Transmission of reports to RMS2-Way link and transmission of video,
images, fingerprintsExternal ID Devices, e.g. Card
Reader, Bar Coding
Mitigating risks of obsolescence
Technology independent visionsAdherence to open standardsEffective project managementThe service oriented architecture
