Wirelessly connect, control and monitor remote assets
For critical infrastructure operators to benefit from the allocation of the 450 MHz band, the right hardware for communication is essential. MC Technologies has already done development work and offers corresponding DIN rail routers and data terminals with proven functionality and reliability for the new frequency band.
Wireless data transmission at 450 MHz is an asset for electricity, gas and district heating providers, water suppliers as well as transport companies and emergency services. It provides a good basis for future-proof digitization in the area of public provision and services of general interest.
Remote plants can be wirelessly connected, monitored and controlled, for example to avoid overloading the power grid or to restore normal operating conditions as quickly as possible after a fault. Typical applications are the power reduction of decentralized power generators such as photovoltaic systems in case of imminent grid overload or the black start of (small) power plants after a grid failure.
Many critical infrastructure operators have already launched initial pilot projects or are already planning regular use of the 450 MHz range. The prerequisite for this is reliable hardware for reliable communication, which MC Technologies has been offering its customers for a long time. When designing devices such as routers or data terminals, the company took into account the need to allow diversity in communication at an early stage. This means that in the new 450 MHz devices, the core functions are provided by the same electronics that are already proving themselves in tough use today.
Critical Infrastructure Monitoring
Monitoring and control functions in one device
The MC92 data terminal from MC Technologies will also be available in the 450 MHz variant. It has multiple I/Os (inputs and outputs) so that monitoring and control functions can be realized with a single device. For example, a water utility can monitor the operation of pumps or control them remotely if needed. The latter is already possible with a simple SMS. In case of critical operating conditions, alarm messages can also be sent via the data terminal.

Multi-frequency modules for critical and non-critical data
In addition, MC Technologies has devices in its program that can use diverse frequency bands. This makes sense if, for example, time-uncritical data such as consumption values are communicated via LTE and time-critical control commands are to be received via 450 MHz using the same hardware. Operators of critical infrastructure can thus derive maximum benefit from the hardware and drive digitization forward cost-effectively at various levels.
