Capestone PSTN to 4G Gateway

Over the next few years, some of the copper connections in the Netherlands will be replaced by fiber optic connections (FTTH – Fiber to the Home) and in the future it is even expected that the majority of these analog connections will be terminated by the cable companies. For a large number of companies, migration to fiber optics will be a great solution. But there is also a significant number of companies and organizations where fiber optics isn’t the solution. This has two reasons, on the one hand the fiber optic connection is too expensive compared to the PSTN subscription, and on the other hand the physical location and that of the connection point can cause problems.

Capestone introduces a unique total solution for the migration of analog connections to 4G with; CAPESTONE PSTN TO 4G GATEWAY®.

Migration from PSTN to 4G – Enormous market opportunity

There are still many Public Switched Telephone Network (PSTN) networks and connections in Europe. The analog endpoint of this network is called POTS, Plain Old Telephone Service, Post Office Telephone Service or Post Office Telephone System and is still widely used to connect all kinds of equipment and machines. Operators and network owners will increasingly end this network service in the coming years to migrate to fiber. Capestone offers a migration solution based on 4G.


Total solution including hardware, connectivity, service and management

The CAPESTONE PSTN TO 4G GATEWAY is an All-in-one solution to easily migrate analog / PSTN connections to a future fixed solution. The CAPESTONE PSTN to 4G GATEWAY is an aluminum housing consisting of a combination of IoT hardware, 4G antenna, software and IoT connectivity solutions to receive analog signals, convert them to SIP and then securely transport them over the internet.

The CAPESTONE PSTN TO 4G GATEWAY is assembled in cooperation with-and based on-A brands. Under the housing runs a robust 4G router from Cradlepoint- part of Ericsson- containing two embedded IoT sim cards from Comgate. This IoT sim solution is primarily based on KPN IoT including Cisco Jasper sim management, the back-up SIM card concerns a Comgate multi IMSI eSIM including our IoT eConnect sim management portal.
