Data Terminal RA5 HF VHF UHF Border Guard Security Agencies Police
Data Terminal for HF, VHF, UHF Radios
FEATURES & BENEFITS:
| AES-256 VOICE, DATA & POSITION FOR ANY RADIO The RA5 is a high performance digital secure voice terminal purpose-built SUPERIOR MODEM PERFORMANCE Long-range communication is especially prone to channel fading. Both |
INFORMATION SECURITY
Beyond-Line-Of-Site (BLOS) communication is vulnerable to eavesdropping. The RA5's built-in AES encryption means that all digital voice and data communications are secured by a trusted algorithm.
LOW-RATE VOCODER
The internal Vocoder digitizes the voice. The information is then encrypted and converted to an in-band signal by the data modem. The Vocoder dramatically improves voice quality in adverse channel conditions, extending the range of voice communications. The unit is also capable of detecting plain voice (analogue SSB or FM).
PRIVATE LINE VOICE
‘Private Line’ conversations are not heard by other units. The unit to call can be selected from the Contacts List.
LOCATION TRACKING
The RA5 built-in GPS receiver facilitates simple navigation functions, position tracking and supports emergency GPS alerts.
SECURE DATA MESSAGING
The RA5 can provide broadcast Chat and point-to-point SMS and Email data communications from headquarters to regional centres and mobile stations. File transfer from an external USB drive is also supported. The unit is menu driven with an intuitive and simple interface.
The Address Book – keypad button – is a convenient entry point for messaging to individuals or multiple recipients. Icons indicate priority level and delivery status of messages.
The Call for Backup – keypad button – gives users peace of mind that messages can go out quickly in a emergency situation. Further menus include rescue and evacuation requests to be sent.
Access to the unit is restricted by means of a Personal Identification Number (PIN). All locally stored messages are encrypted.
Automatic Link Establishment (ALE) can optionally be used to determine the best channel for establishing voice and data links. The transceiver is automatically switched to the correct channel (radio control required). Notwithstanding the use of ALE to control a transceiver, the RA5 can still link with an RA5 on in ‘fixed channel mode’ or with no radio control.
The result is rapid, reliable and secure data messaging using a variety of existing radios.
DT SYSTEM CONFIGURATION Configuration and Key Management is performed using the DT SCS (System Configuration Software) and DT KMS (Key Management System) software. Configuration file and key sets are securely transferred to multiple devices using DT PC GATEWAY (OPTION) The RA5 can provide a "modem mode" in which it connects with the DT GATEWAY Software on a PC via the Ethernet port providing end- to-end Email connectivity. | RA5 DATA MODEM The default RA5 configuration uses a proprietary Advanced Link Set-up and packet data modem for optimised data transmission on radio networks in adverse conditions.
