Evolution & Value of the MOTOTRBO Platform

MOTOTRBO Value Fundamentals Increased System Capacity Breakthrough Performance Improved Productivity Confident Investment

Increased System Capacity 2:1 Channel Capacity Divides existing channel into two timeslots Delivers twice the capacity through repeater Reduced need for combining equipment 40% longer battery life Slot 1 Slot 2 frequency 12.5kHz Channel 12.5kHz TDMA

Breakthrough Performance Better Basics and Advanced Features Ergonomics Durability / IP57 Clearer voice over greater range Background noise suppression Group or One - to - one calling Group or One – to - one text messaging Variety of Digital Signaling Features Available IMPRES

WHY IMPRES AUDIO? Automatic Gain Control (AGC) –Lowers volume when audio signal strengthens (i.e. shouting) –Increases the volume when audio signal weakens (i.e. whispering) Radio reads IMPRES accessory when attached – Adjusts audio level for optimum speaker and microphone Performance No RF adapter needed for PSM Programmable Buttons Meets IP57 Submersible Mil specs –30 minutes up to 1 Meter

Improved Productivity Integrated Applications GPS Tracking –Built in GPS module Text Messaging Telemetry Control and Indication IP Capable Device Limitless options through the ADP –GPS/Text –Consoles –Work Order Software –Option Boards

Confident Investment Simple migration from analog to digital systems –Tri-mode radio: Analog 25/12.5 Khz and Digital 6.25e –Scan between analog and digital –Analog signaling capabilities Future ready hardware Regular firmware upgrades Extended Warranty Standard / Optional Comprehensive

Extended Warranty Standard Extended Warranty on Subscribers at no Additional Charge –2 Year Standard Warranty + 1 Year RSA = 3 Years of Coverage Optional RSA Comprehensive Coverage –Covers against Chemical, liquid, and physical damage Reduce unexpected repair charges Reduce equipment downtime Protect equipment investments Additional Margin for you! Dealer Price = $166.00/unit Suggested List = $195.00/unit You Make = $29.00/unit

TDMA Competitive Update TDMA vs. FDMA

MOTOTRBO TDMA vs. FDMA What makes TDMA a better technology platform? – Standards Based – Easy to License – Provides Easier Migration – Longer Battery Life – Lower System Costs Fewer base stations to support same amount of traffic Dramatically improved system efficiency Less floor space, power, batteries, backup, etc. 12.5kHz Channel Slot 2 Slot 1

Original GPS Configuration: Voice and Data must share same channel When system bandwidth is maxed out, users must be moved to another slot, making it difficult to maintain communication across the entire fleet GPS Data Revert Slot 1 Voice and Data Slot 2 Voice and Data F1F1

GPS Data Revert Current GPS Configuration Option: Data can be reverted to another channel or slot Voice communication can remain on a single slot to maintain fleet communication Slot 1 Voice and Data Slot 2 GPS Data F1F1

This will enable the repeater Ethernet port on the back of the XPR 8300 This will provide end users to link 2 or more sites via IP backhaul: – Across geography – Throughout large buildings – Across a large campuses, such as an amusement park or college Allow communication between sites with different frequency bands (e.g. VHH and UHF) Maximizes coverage, not capacity IP IP Site Connect

B A C D School District Example: One repeater at each site Two time slots for each repeater User initiates a call on Slot 1 for local communications S1 S2 IP Site Connect

B A C D School District Example: User initiates a call on Slot 2 for multi- site communication. IP Network S1 S2 IP Site Connect

B A C D S1 S2 School District Example: Roaming units automatically register and communicate on closest repeater IP Site Connect

MOTOTRBO IP Site Connect: Site Roaming Passive Site Search –Starts roaming based on RSSI –Relies on transmitted voice or beacon –Will not scan and roam –Will not roam in an emergency Active Site Searching –Initiated by a PTT –Attempts to wake each repeater in turn –Allows for roaming in an emergency

MOTOTRBO IP Site Connect: Upgrading ●Legacy hardware is compatible (one caveat) –If the customer requires alarms on fan failure and AC power supply failure with switching battery revert –FRU Kit for purchase for repeaters shipped prior to 1.4 release ●Legacy repeaters MUST be firmware upgraded and reprogrammed ●Highly recommended that subscribers are upgraded as well ●Data applications are FULLY compatible with the IP Site Connect UPGRADE COMPLETE!

MOTOTRBO IP Site Connect: Design Considerations IP Site Connect CAN NOT: 1.Tie an Analog and a Digital Channel Together 2.Tie Analog to Analog 3.Have repeaters that do not match at all sites IP Site Connect CAN: 1.Tie Different Bands Together –Example: Tie UHF to VHF

RDAC over IP Repeater Diagnostics, Alarms and Controls Repeater Diagnostics –Enabled/Disabled –Analog/Digital –Wide or Local Area –Transmit Power (High or Low) –Available Channels (including Currently Selected) –Inbound RSSI –IPv4 Address –UDP Port IP

RDAC over IP Repeater Diagnostics, Alarms and Controls Repeater Alarm Reporting –Receiver Lock Detect Failure –Transmitter Lock Detect Failure –Overheating –AC Power Supply Failure –Main Fan Failure IP

RDAC over IP Repeater Diagnostics, Alarms and Controls Repeater Control –Enabled or Disabled –Change Channels Between Analog or Digital Channels Between Wide Area and Local Channels Between Channels with Different Frequencies Etc… –Change Transmit Power Level (High or Low) –Reset RDAC can be configured to work over the network via IP or locally via USB and GPIO connections.
