RADIO - CHARGER SALIENT CHARACTERISTICS FOR APX 6000.pdf

SALIENT CHARACTERISTICS: APX 6000

The following features, characteristics, and technical specifications are required in order to properly support the mission:

GENERAL CHARACTERISTICS

Systems Operation: Given the wide variety of fielded LMR systems, radios must be able to operate and interoperate on both P25 and legacy, conventional and trunking, LMR systems which use the following technologies:

● Analog Conventional

● SmartNet and SmartZone 3600 baud trunking

● P25 Common Air Interface (CAI) (Digital Conventional)

● P25 Phase 1 FDMA trunking

● P25 Phase 2 TDMA Trunking

● P25 Link Layer Authentication

For P25 features, radios must have a certified P25 CAP SDoC documenting the full set of P25 systems the radios have been CAP tested on.

Secure Operation: All radios must have FIPS 140-2 Level 3 certified encryption modules for use with AES-256 bit encryption. Level 3 is required due to the substantial time and effort required to remediate the loss or theft of a radio with a lower encryption level. Level 3 certification ensures that keys cannot be extracted from the radio, which could jeopardize COMSEC for all issued radios, and require rekeying of the entire radio fleet.

Over-the-Air Manipulation: Having to manually track down issued radios to reprogram or rekey them imposes substantial burdens of both time and cost. The inability to swiftly complete these processes also detracts from the communications squadron’s mission. Where a P25 LMR system is present, the radios must be capable of Over-the-Air-Rekeying (OTAR) and Over-the- Air-Programming (OTAP) operation. Where no P25 LMR system is present, the radios must be capable of being rekeyed wirelessly using a Key Loader and a Donor Radio.

Programming Parameters Database: Updating the programming parameters of large numbers of radios can be an extremely time-consuming process. Radios must be capable of storing programming parameters in a centralized database, from which batch parameter changes can be made to large numbers of radios, and distributed by an automated mechanism. Radios must be capable of participating in batch programming update pushes from this database. This greatly reduces the time to update radio programming and leads to significant labor cost savings.

Dynamic Addressing: Where a P25 LMR system is present, users will need to access the system to manage radios and OTAR / OTAP operations. To maintain the security posture of the various fielded LMR systems, this access must be restricted to the lowest possible level of IT privileges.

In order to perform OTAR and OTAP without requiring access to critical system databases, portables must be capable of receiving a dynamically assigned IP address from the system upon powering up.

Voice Announcement: Radios must be capable of providing a user-definable voice annunciation of channel changes. This allows users to change channels in dark or smoke filled environments, and be aware they are on the correct channel without having to see the radio.

System Roaming: Where a P25 LMR system is present, radios should roam based on monitoring of adjacent sites, a multi-level preferred site assignment scheme, and preemptive site reselection parameters. Roaming based on these parameters ensures that the P25 LMR system is not overloaded, and that all users experience consistent quality of service throughout the maximum extent of the coverage area.

Conventional to Trunk Channel Emergency Revert: The subscriber must allow a user operating on a conventional point to point channel to hit the emergency button forcing the subscriber to revert to an emergency trunk channel. If, in an emergency a Soldier using a conventional point-to-point ground channel when inside an area with poor coverage, their radio also has a trunked emergency channel programmed when the emergency button is hit. The radio must automatically revert to the emergency channel when the emergency button on the radio is hit.

This is a life safety issue.

OTHER CONSIDERATIONS

Programming Support: Due to the large number of currently fielded radios, and the wide variety of programming parameters and templates in use (talkgroups, ergonomics configurations with the radios, etc) it is critical to be able to export programming parameters from the existing radios, and then import those same parameters into the new radios. Having to manually recreate hundreds of programming templates would be a multi-year effort, at significant additional cost.

Training: Two basic sets of training will be required: Programming and template building training, and end-user operational training. The programming training should be an exhaustive, instructor led course for radio administrators. The end-user training should be computer-based training (Flash or Powerpoint) tailored to the specific programming template of each user group.

Accessories: Radios should be capable of reusing existing accessories to the extent possible. In particular, existing portable radio chargers must be capable of a retrofit to accommodate new portable radios. Replacing all existing radio chargers would incur a significant additional and unnecessary cost.

PORTABLE RADIO TECHNICAL CHARACTERISTICS

Audio Processing and Optimization: The portable radios must include an audio processing and optimization capability, which automatically adjusts wind porting, microphone gain, speaker equalization, background noise suppression, and dual sided operation without user intervention, to optimize the voice transmission and reception characteristics of the user.

Adaptive Noise Cancelling: Portables must include at least 3 microphones in an array that automatically adapt during a conversation to utilize the microphone best suited for human voice, while the other microphones are used to sample and filter out background noise and wind. To improve noise cancellation, microphones should be mounted on both the front and back of the radio, and spread top to bottom.

Display Colored Lighting: Radio must provide lighting & colored indications on both the displays and keypad to visually notify users of incoming calls, potential emergencies, and system events (i.e. low battery, out-of-range).

Top-Mounted Display: Radio must have a top-mounted display with multi-color backlight to support 1 line of icons and 1 line by 8 characters of text and display zone / channel information as well as signal strength and battery life indicator Glass Display Lens: Portable must be manufactured with a durable high-strength tempered glass display lens on the front main display for clear viewing through polarized lenses and high resistance to scratching and impact. Polycarbonate displays provide neither the user clarity of vision when wearing protective equipment, nor the durability for the mission requirements.

Automatic Gain Control: The Portable must have an Automatic Gain Control feature to automatically adjust microphone gain to compensate for differences in voice level and radio operation.

Audio Output: Portable Radios shall have a speaker rated at not less than 3 watts of audio output.

Intrinsically Safe Operation and Ruggedization: In order to meet mission requirements, a highly rugged, intrinsically safe portable radio is required. Portables must meet certifications for UL TIA 4950 Division 1 : Class I - Group C & D : Class II - Group E,F &G. The III, T3C, Division 2 :

Class I - Group A,B,C & D operation. The radio must be capable of MIL-810 Classifications C, D, E, F & G and Method 512.X procedure. The Portable must be capable of IP68 immersion to a depth of 2 meter for 4 hours. Radio, battery and accessories must be UL approved as Intrinsically Safe as a system.

Automatic Battery Health and Reconditioning: Portable must be equipped with intelligent batteries for fuel gauge accuracy and automatic reconditioning. Intelligent batteries must have internal circuitry to record the charging, discharging and reconditioning history of the battery and be able to communicate with a smart charger so that the smart charger can appropriately recondition batteries as needed to maximize battery life: this greatly extends the service life of the battery. Non-reconditioning batteries need frequent replacement over the life of the portable, and can lead to significant added costs.

Automatic Man-Down capability - Portables must have an integrated man-down sensor that automatically sends an emergency with GPS coordinates if the user becomes incapacitated. This is a Life Safety Issue: First Responders must be capable of monitoring for scenarios where a user is knocked off their feet or incapacitated in a potentially dangerous situation. In order to facilitate this monitoring no additional equipment should be required and the monitoring of the end-user being safe should be configurable on multiple levels to match different first responder roles on a talk-group basis. First Responders will need to be aware of an impending emergency alarm and should be notified via the radio of such.

P25 Tier 2 Location Services. Portables must be capable of transmitting GPS coordinates via P25 Trunking IV&D system for map display. The radio must support dynamic GPS Polling – based on Distance Traveled, Time, PTT, Emergency Press, and Man-Down.
