RI-5500 HF/VHF/UHF Modem

Digitized Encryptor Terminal For Secure Data/Voice Transmission 

The encryptor terminal employs a number of independently developed sophisticated technologies, particularly PAEKHO error-correction code (unique and non-existent in other parts of the world) and spread-spectrum, ultra low-bit rate speech encoding and strong encryption plus veteran workmanship.

- Speedy, uninterrupted and secured communication in extremely difficult environment subjected to all possible impediment factors, namely, gauss noise, multi-path delay, fading, speech band-related noise and cross-interference.

- Reliable, error-free data transmission even in extremely difficult conditions under strong spectrum jamming with its time factor reaching nearly 90%.

- Undetectable, stealthy communication.

- Built-in protective system against unwarranted use.
