Garderos will present its LTE-450 routers and secure communication solutions for critical infrastructure at E-world energy & water 2026 (Hall 5, Booth 5M116). The focus is on reliable, highly available connectivity for energy utilities, grid operators and the scalable operation of EV charging infrastructure.

Modern communication architectures for critical infrastructure

At E-world 2026, Garderos demonstrates how modern communication architectures based on LTE-450 routers support energy utilities and grid operators in strengthening operational resilience and modernising existing network infrastructures. Garderos will showcase its LTE-450-capable routers, which are approved on the whitelist of network operator 450connect and designed for highly available operation in critical networks.

A further focus is the virtual RTU for low-voltage monitoring and protocol conversion in secondary substations. In specific scenarios, it can replace a physical RTU and support more flexible grid operation. Garderos will also present solutions for the migration from 4G to 5G RedCap and provide guidance on a topic that is already relevant today and will continue to gain importance in the coming years.

Router solutions for operational reliability and cyber security in EV charging infrastructure

In the area of EV charging infrastructure, Garderos’ communication architecture increases operational reliability while reducing management effort. Industrial routers and the central management system form the backbone of a scalable solution, supporting redundant connectivity options such as 5G/4G, LTE 450 and fibre, combined with integrated security mechanisms.

Garderos solutions help energy utilities, distribution system operators, and operators and providers of EV charging infrastructure meet regulatory requirements while reducing day-to-day operational effort. Support for eSIM, eUICC and remote SIM provisioning simplifies rollout and fleet management across large numbers of sites.

Detailed requirements and selection criteria for KRITIS-grade LTE 450 routers can be found in the Garderos Buyer’s Guide (in German).
