Telegram splitting raises the effort required to jam a mioty transmission: because bursts are short and spread across the band, a narrowband jammer only reaches a fraction of them, and the forward error correction absorbs that loss. A broadband jammer with enough power can still disrupt any radio system operating in licence-free spectrum, mioty included. The realistic claim is increased resilience against interference and narrowband jamming, not immunity, and this sits under what the security guideline calls Quality of Connection, a distinct property from confidentiality or authenticity.
