Introduction to Configurable Radio Fence (CRF)

Updated: Mar 21, 2019

Let’s get familiar to the word CRF – Configurable Radio Fence. It is a proprietary flagship technology developed by Vacus. The primary use case of CRF is to track and trace business-critical assets in an indoor environment for efficient productivity and safety monitoring. The use-case has a potential impact on a broad segment like data centres, warehouse, smart buildings, manufacturing, defence and aerospace etc.

Most other existing indoor technology as researched and studied, are neither reliable nor accurate. The fundamental principle for building our technology was that the product should not only offer reliable and consistently precise micro-location but also to offer efficiency and experience which is tailor-made to the specific use-case.

The CRF solution consists of a Zone Monitor and Tag. The radio tags broadcast their presence to the zone monitor at programmable intervals. CRF is a virtual boundary created by Vacus’s Zone-Monitors in which our radio tags can be tracked and located reliably with an accuracy of 30 cm.

The system is based on Fog computing to carry out a substantial amount of processing. This is to reduce the load and increase speed and reliability. It uses MQTT protocol to integrate with the partner based IoT platforms. Our product sets itself apart from the competition by offering the flexibility of easy integration with other sensors to cater to the varied requirements for the diverse applications of our technology.

The USP’s of CRF:

- CRF is immune to the problem of signal multi-path:

Signal multi-path is one of the most significant issues plaguing the micro-location industry. By intelligently designing and positioning our antenna, we able to filter out reflected signals and accurately position and track objects in our fence reliably.

- CRF can accurately tell the azimuth angular sector of the arrival of the signal.

- CRF is Fog enabled: The majority of the processing of the received signal is carried out in the antenna structures on the modules. This makes the solution power efficient and economically viable.

At Vacus, we believe that the real power of technology can be realised only when it is simple enough to be understood and used effectively by everyone.

We love the developer community, and hence, apart from the products we already offer, we also have an Evaluation kit which the maker community can get their hands-on innovation.

Stay tuned for the next few blogs where we detail the products and their various use-cases, starting from the data centre use-case.
