Forces operating in satellite-limited and contested battlefield environments rely on advanced, secure, beyond-line-of-sight (BLoS) communications. That's why Collins Aerospace provides modernized, high-frequency (HF) communications systems that provide all the communications capabilities needed with very low day-to-day operating costs. Today, modernized Wideband HF (WBHF) can deliver rates up to 240 kbps on a 48 kHz wide channel, opening the door for HF to deliver the same level of data transmission speeds, quality and security as narrow-band SATCOM systems.
