RC66 Combat Communication Suite

The AT Communication International RC66 Combat Communications Suite simplifies setting up a high frequency (HF) network by seamlessly integrating Internet and HF e-mail. Compatible with standard e-mail applications such as Microsoft Outlook™ the RC66 enables sending and receiving e-mails efficiently and reliably over HF radio links and the Internet and confirms the success/fail of HF e-mail transmission via confirmation e-mails.

RC66 contains a STANAG 5066 ARQ protocol stack that provides interoperable, networked, error-free and efficient communication over HF radio links and is interoperable with STANAG 5066 e-mail clients of other leading vendors.

Prioritization of E-mails 

The RC66 increases throughput by means of RFC 1952 standardized compression as mandated by STANAG 5066 Annex F (CFTP), which supports prioritization of e-mails, sending higher priority e-mail first. Should the transmission of an e-mail be interrupted or preempted by a higher priority e-mail, the interrupted e-mail will be resumed at an appropriate time.

Maximization of Signal and Link Quality over ALE

As an option, the RC66 enables multi-frequency operation via the optional RM6A ALE modem.

RC66 continually maximizes throughput by monitoring the signal quality and adjusting the data rate in accordance with the link quality. If the radio channel is no longer viable for communication the ALE is used to select a different channel for continued communication (ALM channel change).

RC66 GUI Features

• Assisted Network Configuration
• E-mail delete/re-prioritize
• E-mail throughput/utilization
• Channel status (SNR, BER)
• Radio status, S-meter, VSWR

Caption: The RC66 GUI assists the HF Network Administrator to define a hierarchical HF Network layout without complexities associated with ALE and STANAG 5066. The RC66 allows HF Network configuration to be updated when new nodes are added or removed.

Operational Modes 

The RC66 structures status information to allow the user to pinpoint faults, failures and inefficiencies in the HF Network.

Features:

• ARQ Mode
• Broadcast Mode
• Voice Mode
• Radio Silence Mode

Voice or Data Selection

The RC66 gives the user complete control to use the radio for data or voice transmission as required by the user; it has the ability to sense the PTT signal allowing the RC66 to automatically stop data transmission when the user uses the radio for voice transmission.
