Easy to Install.
Easy to install software.
The PDA-184 software is government-developed,
government-owned, and is available from DISA
as part of this total solution.
a Graphical User Interface (GUI) that allows
radio users to transmit and receive a variety
of data types at much higher speeds than is
possible with comparable proprietary solutions.
The implemented Data Control (DC) waveform
enables more reliable data communication
by providing data compression, packet
communications, and adaptive error-correction
processing of user data to allow high-throughput
and reliable data transfer even over noisy
communication channels.
• Developed and supported by DISA
• Easy to confi gure GUI
• Transmits and receives data at much higher
speeds than with comparable proprietary
solutions currently available
• Delivers reliable communication via:
– Data compression
– Packet communications
– Adaptive error correction
• Provides reliable high-throughput data
transfer over noisy communication channels
• Designed for use with HF, UHF, VHF, and
SATCOM radios and networks
• Versatile enough to be applied to data
communication networks that use other
wired or wireless transmission media
• Innovative link layer software design for
speedy customization
• Quick Installation
– Few simple steps
– Automatically installs the necessary fi les
and programs to the target disk
