Ultra-compact and rugged wireless routers enhance connectivity to remotely located equipment and systems in demanding utility, infrastructure and transportation applications.

Westermo has expanded its range of industrial cellular routers designed to provide resilient data communications for remote sites. The new Merlin 4400 series of ultra-compact and rugged LTE Cat 4 wireless routers has been developed specifically to support extremely secure remote access to equipment and systems within demanding utility, industrial and trackside applications. High connection security gives users the confidence to expand their IP networks to include remote assets.

Resilient and reliable high-speed data communications are essential to the digitisation of the rail network, the implementation of smart grids and improving the operational performance of utilities. Network security is a fundamental requirement in these applications and to defend against increasing cyber threats, the Merlin 4400 series is equipped with a complete set of cybersecurity tools as standard. These include a TPM (trusted platform module) chip that keeps cryptographic keys secure, Secure Boot functionality ensuring the routers boot using only trusted software, and virtual private network (VPN) and stateful firewall support for data security and user authentication.

The Merlin 4400 series offers high-speed connectivity, with support for Ethernet and RS-232/485 communications to ensure suitability for a range of applications. It is suited to replace traditional modems when migrating to an IP infrastructure. Serial ports enable connection to legacy devices and equipment, and a built-in protocol gateway enables seamless connection to multiple devices using different communication protocols.
