As mentioned above, the Wireless Mesh Modbus Extender is supported by Radiocrafts’ Sub-GHz Mesh solution, RIIM, to support wireless Modbus signals.

By extending the Modbus signal wirelessly using RIIM, you create a highly efficient network which supports reliable sensor reporting, low latency actuator control, and long indoor building range, all in a single wireless network. These benefits allow you to scale your wireless Modbus network reliably to cover an entire skyscraper or campus with up to 700 devices in a single network and a data packet delivery rate of 99.99% or higher. On top of that, the Sub-GHz frequency provides long range and can easily penetrate through reinforced concrete walls or steel beams to reach devices in hard-to-reach places like an underground parking lot or basement.

There are several drawbacks with wired solutions which can be mitigated by going wireless. For example, installing kilometres of copper and fiber optic cables is expensive and labour-intensive in large buildings complexes. Furthermore, cables are vulnerable to all kinds of damage such as from the weather, animals, and simple wear and tear which can be costly to repair. One single point of failure could shut down the whole system. Finally, expanding or upgrading wired solutions requires a tremendous amount of work including structural re-engineering of the building complex and disruptions to current functions. Wireless solutions provide simple answers to these issues.

With a wireless solution, the cost of ownership is reduced significantly because it reduces the need for expensive cable installations and frequent maintenance work because there are no cables to repair or replace. Instead, what you get with wireless is a non-invasive and quick plug-and-play installation experience making it ideal for both new and old buildings alike. Wireless solutions are also easily expandable and can reconfigured to support a future-proof solution which can last decades.
