RadioPro™ Link gives each RadioPro™ IP Gateway a fixed endpoint URL, so RadioPro Dispatch, Solo, the Talk mobile app and ICU can reach it from anywhere — even when the Gateway sits behind Starlink, cellular, or any other internet connection that uses carrier-grade NAT (CGNAT). No static public IP address, no port forwarding, no VPN, and no requests to your internet provider in most cases.

Why Remote Access Breaks on Starlink and Cellular

Many internet providers, including Starlink and most cellular carriers, place customers behind carrier-grade NAT (CGNAT). The site's router shares a public address with other subscribers, so an inbound port-forwarding rule cannot open a path to the Gateway. Remote clients lose their connection, and remote configuration through ICU stops working.

How RadioPro Link Works

RadioPro Link replaces the site's changing public IP address with a stable endpoint provisioned by CTI. Clients connect to that endpoint, and the Gateway reaches it over whatever internet connection is available at the site. Traffic is carried over a single port and is encrypted end to end.

Getting started is simple:

1. Choose a name for each Gateway
2. CTI provisions the endpoint and ships a preconfigured Gateway
3. Connect the Gateway to any internet connection
4. Point your clients at the endpoint URL instead of an IP address

With DHCP enabled, a Link Gateway can move between networks — from wired fiber to Starlink to an LTE hotspot — and clients keep using the same endpoint. RadioPro Link supplies the network path; the Gateway still needs a working internet connection and the control station still needs RF coverage of your field radios.

Supported Applications

Gateway accounts, client permissions and RadioPro licenses still apply. Contact CTI or your dealer to confirm compatible Gateway and client versions.

Starlink Field Testing

Tested on Starlink Mini, stationary and in motion

In September 2026 CTI tested RadioPro Link over a Starlink Mini on the Roam plan, with a RadioPro client on wired office internet. Figures below are client-to-Gateway network timing; they do not include radio call setup or the RF path.

In-town outages were roughly 5–10 seconds each, most likely caused by buildings and trees obstructing the dish. The Link connection recovered automatically every time.

Results from one test configuration; not an uptime or performance guarantee for another site. See the full Starlink Mini test results.

Where RadioPro Link Fits

Put a radio channel online wherever there is internet

• Disaster recovery — stand up dispatch on Starlink when wired service is down
• Rural and remote sites — where satellite or cellular is the only option
• Mobile base stations — Gateways in vehicles or trailers that move between locations
• Temporary job sites — move the Gateway between projects without reconfiguring clients

• Remote management — configure Gateways with ICU without visiting the site
• Simplified setup — no router changes or IT tickets for typical installations
• ISP-agnostic — switch providers without changing client settings
• Starlink backup — keep a secondary path ready behind your primary connection

Basic Dispatch testing over a Verizon 4G LTE MiFi showed no noticeable added audio latency. Geostationary satellite links work mainly for remote configuration, since their 500–600 ms latency is high for live voice.
