3 P a g e 3 General System Overview The Motorola MOTOTRBO system shall provide reliable, efficient, radio functionality for North Lawrence Community Schools Transportation Department operational groups and shall accommodate Transportation and Schools operations communications requirements between these operational groups. The Radio System shall be provided with the features, functions, and capabilities as described herein. Required Features and Functions The proposed Radio System and protocol shall support the following features and functions: 1. The system and/or user equipment must support digital transmissions on a 6.25 equivalent, 12.5 khz TDMA channel. The system and/or user equipment must also support analog transmissions on 12.5 khz channels. 2. The Motorola repeater/base station equipment must be able to manage two independent time slots on a single 12.5 khz frequency using TDMA (Time Division Multiple Access) technology transmissions. 3. All portable radios must incorporate increased digital battery life over analog by operating in a TDMA digital mode. 4. All portable radios must include battery technology for automatic maintenance and reconditioning. 5. All radio equipment must support the use of radio subscriber accessories for automatic gain control and noise suppression. 6. The system and/or user equipment must include imbedded digital forward error correction technology to increase clarity throughout range. 7. The system and/or user equipment must include imbedded software based privacy or scrambling to protect user privacy during

4 P a g e 4 communications. This imbedded scrambling must support at least 40-bit protection with multiple keys. 8. All radios must include Emergency Declaration capability with single button activation. The Emergency Declaration shall provide visual and audible status notification to specified radios. The Vendor s Proposal shall include a detailed description of the Emergency Declaration features and programming options. 9. The system and/or user equipment must include imbedded GPS receivers in both the portable and mobile radios. Any additional external receivers or accessories shall not be required to receive or send GPS information. GPS shall be supported in a repeater mode. GPS antennas are not required at this time as GPS will be activated in a later phase. 10. The system and/or user equipment must include imbedded text messaging capabilities. Any additional external receivers or accessories shall not be required to receive or send text message information. The user equipment must support unit-to-unit canned and user creatable text messaging capability. The user equipment must support at least 140 scrolling characters. Text messaging shall be supported in a repeater and/or talk around mode. 11. The system and/or user equipment must include imbedded telemetry capabilities. Any additional external receivers or accessories shall not be required to receive or send telemetry information. Telemetry shall be supported in a repeater mode. It is assumed that telemetry from a vehicle will be by exception. Further support will be required to implement any telemetry connections. 12. The system and/or user equipment must include intelligent channel steering capabilities to revert GPS traffic to alternate channels to control and manage data traffic more efficiently on the system.

5 P a g e Automatic Vehicle Location (AVL) information shall include vehicle identification, location, speed and time of transmission. 14. Voice shall take priority over data transmissions on radios transmitting both voice and data information. 15. The system user shall have the option of applying for licensure to detailed radio interface information. This information shall allow the radio user, if capable, to develop custom applications. 16. The system shall provide a software application that allows the system administrator the ability to monitor and control the radio repeaters within the system. The Repeater Diagnostics and Reporting system shall provide the following capabilities: a. Repeater Diagnostics that include enabled-disabled station status, transmitter power status, available channels and RSSI levels. b. Repeater Controls that include changing channels, transmitter power, station reset and repeater knockdown. c. Repeater Alarm Reporting including receiver lock failure, transmit lock detect, station overheating, AC power supply failure and detect and report of failure. d. The application operates over the IP network or locally via USB or GPIO connection. e. Repeater Alarms: RX (Receiver lock failure), TX (transmit lock detect), Temp (station overheating), Power (AC Power supply failure), Fan (fan failure).

6 P a g e 6 Motorola MOTOTRBO Capacity Plus Trunking Conventional Capabilities: 1. The system shall be a UHF single-site, multi-channel radio network capable of supporting multiple interconnected user groups/fleets. Various entities and work groups must be able to communicate without regard to geographic location within the coverage area. 2. Future: The system design should allow connection of any site in the network to any site in the network over IP (Internet Protocol) to achieve the required network connectivity between sites. The network infrastructure should allow the system operator the flexibility of being able to configure the network in a linear, star or mesh type of network configuration. 3. Future: System capability should allow expandability to support additional and/or future sites, radio channels, and users. The network should have the capability of being expanded to at least 15 sites. 4. Future: The system design should allow seamless roaming between sites: The system shall provide for automatic radio switching between network sites without any action by the user to provide communications without any message interruption throughout the designated coverage area. 5. The system shall have the ability to remotely disable and enable a radio from a central location. 6. The system must support data traffic on available timeslots in the pool of resources. 7. The system shall be capable of supporting data communications that include GPS location services, text messaging, and a data interface for other customer specific and supplied applications including telemetry, system performance management, VoIP dispatch, AVL, work-order management, and connectivity. 8. Future: In the event of a wide area link failure, the system shall continue to maintain its local repeater operation and shall continue to provide wide area communications where a wide area link is still available between sites.

7 P a g e 7 Radio User Equipment General All user radios proposed (portables, mobiles, TrboVUi, and control stations) shall fully support all features and functions available for user radios in the Motorola MOTOTRBO system.
