Fighting eavesdropping and interference

National defence communication networks must be able to transport sensitive data with the utmost reliability and security. When it comes to wireless transmission, one highly secure method is frequency-hopping spread-spectrum (FHSS) radio technology, which involves spreading a signal over rapidly hopping radio frequencies. This technique is resistant to interference and difficult to intercept. It does, however, require an extremely precise time reference with extended holdover performance that ensures long-term stability for critical missions. Our OSA 3030B, already deployed by some of the world’s largest national defence organisations, easily meets FHSS requirements for accuracy and fallback.
