2. Digital Strategy Launch

3. General Digital Benefits ● Improved performance and extended range ● Clear, consistent audio quality ● Increased systems capability vs. analog  Text messaging  Enhanced call management ● Better spectrum efficiency ● Regulatory requirement

4. Digital Delivers Increased System Capabilities vs. Analog Clear Voice Quick Communications Enhanced Call Management Security Call Routing Dispatch and Control Location Range and quality Free form text. Canned messaging. Selective private call, group call, group management Inherently secure with encryption levels Dedicate specific slot as either voice or data IP-based dispatch. Embedded telemetry I/Os. GPS tracking, vehicle reporting, etc.

5. TDMA Digital Advantages ● Doubling of capacity in current spectrum ● High data rate for enhanced call features ● 40% increased radio battery life Effective transmit time cut in half with two-slot TDMA Overall battery consumption per call dramatically reduced ● 50% lower repeater costs vs other digital & analog ● Reduced combining equipment ● Global ETSI standard called DMR Developed by the European Telecommunications Standards Institute (ETSI) as a replacement for analog radio technology Globally available, open standard for greater flexibility

6. TDMA vs. FDMA: Compare the Benefits NoYes Open standard for more choices? CapabilityTDMAFDMA Achieve spectrum efficiency? YesNo Use existing licenses? YesNo Battery life improvement? YesNo Channels to repeater ratio 2:11:1 Combining equipment required? NoYes Simultaneous voice and data per channel? YesNo

7. TDMA Digital: Good For Narrowbanding ● Meets FCC requirement for user’s license to be on 12.5 kHz channels by Jan 1, 2013 ● Enables users to keep valuable 12.5 kHz channels and double capacity ● Meets FCC recommendation that users migrate directly to 6.25 kHz efficient equipment ● Meets requirements for manufacturers to have 6.25 kHz efficiency or equivalent built into radios  12.5 kHz TDMA is an equivalent
