One telecommunications company. Three network disciplines.
Horizon Network Plus delivers wholesale voice, mobile core networking and carrier-grade NAT under one brand: carrier-grade VoIP through Horizon Voice, 4G/5G core network infrastructure through Horizon Mobile Networks, and CGNAT with NAT64 through Horizon CGNAT.
Diagram: Horizon Network Plus is the parent brand. Three separate taps leave it and lead to three independent product families — Horizon Voice, a carrier voice route; Horizon CGNAT, a carrier-grade NAT between private subscribers and the public IPv4 Internet; and Horizon Mobile Networks, a 4G and 5G mobile core topology. The product families are not connected to each other.
