LTE Broadband Private Network
Caltta's LTE broadband trunking private network is built on 4G/5G LTE standards, compliant with 3GPP and B-TrunC. While safeguarding mission-critical voice (call setup <250ms), it carries voice, video and data multimedia services on a single network — the core choice for broadband upgrades in government, public safety, rail transit, airports, ports, and energy sectors.
The LTE private network supports frequency customization, flexible fixed and mobile networking, and seamless indoor/outdoor coverage. It works in synergy with narrowband DMR and public PoC to build a converged "narrow-broadband, public-private" communication system.
