CHANNEL SPACING
There are no maximum frequency separation conditions that must be adhered to on the APX 6500 Mobile series. Separation of frequencies can be as wide as the allowable band per radio model with no degradation of any performance specifications. If an incorrect antenna is used, degraded performance may be experienced.

PROJECT 25 ENCRYPTION
The mode of operation is programmed on a channel-by-channel basis. With the coded/clear switch set to the clear mode, the ASTRO Digital APX6500 radio is capable of transmitting clear analog voice or clear (unencrypted) ASTRO Digital voice, depending on the channel programming. With the coded/clear switch set to the coded mode, the ASTRO Digital APX 6500 radio will transmit ASTRO Digital encryption depending on the channel programming. ASTRO Digital encryption provides secure communications. ASTRO Digital Encryption (operation in encrypted mode while also operation in 3.6KB or 9.6KB and TDMA ASTRO mode) is capable of XL type encryptions; ASTRO Digital Encryptions does not operate with non-XL encryptions.

An encryption option is not required for either clear analog operation or clear ASTRO Digital operation. ASTRO Digital APX 6500 radio functions include selected ASTRO digital signaling and digital speech coding.

When ordering any of the Encryption Algorithms:

• The DES-OFB and AES encryption algorithms offered are compliant with digital Project 25 standards and does not support analog encryption operation.
• Requires the ASTRO Digital CAI (G806) to operate the DES-OFB and AES encryption.

If ordering a Dual Encryption:

• The non-OFB encryption (XL versions) can be operated in either analog, or CAI digital mode, but will not be Project 25 compliant.
• Requires the Multikey (W969).

When used in CAI mode, the non-OFB Encryption will not be Project 25 compliant. 

• Encryption Algorithms can be ordered later via Flash Port.

FIPS 140-2 Compliance
Encryption Modules equipped with AES are FIPS 140-2 compliant. Details regarding the certification, and copies of the relevant certificates, can be obtained on the NIST website at: http://csrc.nist.gov/groups/STM/cmvp/validation.html.
Further information regarding FIPS 140-2 certification may be found using the following link - FIPS 140-2 Crypto Module Validation Program (CMVP) http://csrc.nist.gov/groups/STM/cmvp/index.html

ASTRO Text Messaging Service
ASTRO Text Messaging Service is available on the ASTRO 25 APX 6500 mobile radios with the O5 control head (single and dual-control head) and O3 control head. Text Messaging Service (TMS) allows subscriber users to send and receive text messages to other subscribers or dispatch operators. Users can select messages and addresses from a predefined list or enter freeform text messages and addresses via the keypad. Text Messaging Service is available on ASTRO Trunked IV&D Systems and Subscribers.

For full Text Messaging functionality, including freeform text messaging and addressing, must order O3 Control Head or O5 Control Head with Keypad Microphone. O5 Control Head without the Keypad Microphone supports Limited Text Messaging functionality such as selecting predefined messages or addresses from a list programmed in the radio.

Ordering requirements for APX 6500 Mobile:

• Requires O5 Control Head (G442) or O3 Control Head (G72)
• Full functionality including free form messaging requires the Keypad Microphone (W20) for O5 Control Head
• ASTRO Digital CAI Operation (G806)
• SmartZone Operation (G51)
• ASTRO Project 25 Trunking 9600 Software (G361)
• Packet Data Interface (W947)

NOTE: There is no specific option to order for the Text Messaging Service on the subscribers as the functionality is included in the Packet Data option.

Outdoor Personnel Location Global Positioning Satellite (GPS) Feature
The personnel outdoor location tracking GPS feature enables a dispatcher the ability to locate on-foot patrols and out of the vehicle officers who are involved in life threatening situations. The radio user’s GPS position information is sent over the ASTRO 25 Integrated Voice & Data (IV&D) network and is delivered to the dispatch operator using a third party mapping display application at the dispatch center (Mapping Application is not yet available through Motorola at this time, however an Application Developers Tool Kit is available for 3rd party vendors to use to modify existing applications. See link below for more details.) It is possible to the user to determine their own location (latitude/longitude) through the use of the location menu.

Ordering GPS for APX 6500 Mobile Requires:

• Enable Internal GPS Operation (GA00782)
• Packet Data Interface (W947)

NOTE:
The GPS feature uses radio signals from earth orbiting satellites, to establish the location co-ordinates maximizing your view of clear. Unobstructed sky is essential for optimum performance. When adequate signals from multiple satellites are not available, (usually because you cannot establish a wide area view of the sky), the GPS feature WILL NOT WORK. Such situations include but are not limited to:

• Underground locations
• Inside of buildings, trains, or other covered vehicles
• Under any other metal or concrete roof or structure
• Between tall buildings or under dense tree-cover

VHF SELF-QUIETING SPURS

Note: There are no self-quieting spurs for 700/800 MHz.
