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
