Radiocrafts' Solution For Emergency Lighting Networks - RIIM

The requirements on the network for a successful wireless emergency lighting system deployment include: 

  • Quick and easy network integration and deployment.
  • Long range for coverage of an entire building complex.
  • Ultra reliable communication and operation in building complexes where the floors are made of reinforced concrete and high levels of interference from other radio solutions is present.
  • Cost-efficient solution with minimum of equipment, remote maintenance possibilities, and no license/subscription fees.
  • Long battery lifetime for emergency lights located in hard-to-reach places and for easier maintenance.
  • Test luminaires from anywhere at anytime, including function tests, duration tests, automatic logging, and automated failure alerts.
  • Perform real-time monitoring of current status and incidents.
  • Perform remote software upgrades and maintenance monitoring, including alerts for end-of-life products, as well as lamp, LED, and battery failures.
  • Integrate emergency lighting with building security and access systems
  • Generate analytics to determine building occupancy rates and traffic patterns.
  • Localised sensors which can identify where the hazard is and use emergency lighting to show the best path to safety.

Radiocrafts’ Industrial IP Mesh, RIIM, provides a highly efficient solution to these Emergency Lighting requirements.

RIIM by Radiocrafts is a low code Industrial IoT wireless IP mesh network completely embedded in a module. It includes all the critical components for a complete wireless IP mesh and has no license fee or subscription costs. It is ready to go when you buy the module. Additionally, since RIIM is a mesh network, it is self-forming, self-healing and self-optimizing. This is simplifies the installation, integration, and implementation of your Emergency Lighting network greatly.

RIIM can cover building complexes as large as 2.8 square kilometres long (3.5 miles). It also supports up to 700 meters between each mesh hop (28 mesh hops maximum), and up to 1000 emergency lights for a single border router (gateway), creating flexibility in terms of border router placements and reducing the cost of installation significantly as only a single border router is needed to support a large scale deployment in a massive building complex. To cover a larger area you simply add another border router.

You can read more about RIIM range test results, including inside our building complex in the application notes below.

In addition, the RIIM Mesh Router can handle down to 118uA @ 3.3v average power consumption enabling all battery devices in the network to further extend the network coverage.

RIIM operates on the 868  MHz and 915 MHz frequency bands which offer much better range than the 2.4 GHz frequency band solutions.

RIIM provides unmatched reliability for Emergency Lighting networks thanks to the supported Time-Synchronized Channel Hopping and Adaptive Frequency Agility features.

Time Synchronized Channel Hopping (TSCH) is a channel hopping mode designed to make a mesh with less packet collisions and higher reliability. A TSCH network has proven to have a reliability of up to 99.99%. 

Adaptive Frequency Agility provides industry-leading low latency data throughput with minimal packet loss by taking the allowed duty cycle in Europe from 1% to around 40%! AFA takes works by scanning all channels and marking the ones which are often found to be noisy, then it drops those channels from the hopping list which ensures that the radio only uses the best channels with the least noise.

The combination of these two features provides unmatched reliability which is essential in Emergency Lighting networks located in building complexes where the floors and walls are made of reinforced concrete and high levels of interference from other radio solutions are present. Good penetration in building material will significantly simplify radio coverage planning and enable you to reach that last emergency light mounted in the corner of the building parking lot or other hard-to-reach places. In addition, localised sensors can identify where a hazard is located and use the emergency lights to reliably show the path to safety.

You can read more about TSCH and Adaptive Frequency Agility in the application notes below.

RIIM provides efficient local control and maintenance of nodes through mist computing and two-way symmetrical communication, enabling Over-The-Air updates as well. 

RIIM includes the ICI framework. An ICI application is always running on the module to tailor the modules behavior to the customers unique requirements. In its simplest form, the ICI application is just configuring the modules hardware interfaces, the radio network, and defines when to read and write to those interfaces. ICI also supports mist computing which allows you to control each emergency light and sensor locally, significantly reducing bandwidth requirements, and allowing for fast responses to local events such as, performing real time monitoring of room status and hazards, alerts for end-of-life products, lamp/LED/battery failures, generate analytics to determine building occupancy rates and traffic patterns, testing of luminaires, integration with building and access systems and more.

A RIIM network supports 2-way symmetrical communication which is essential for Over-The-Air updates.  This means that the user can update their user defined ICI firmware when the network is deployed and in full operation, so new sensors/controllers can be added when the need arises and the user can broadcast messages of new schedules efficiently. With emergency lighting systems, often times, many sensors and emergency lights are located in hard to reach places and will be in operation for a long time, so touch less updates of firmware is important.

RIIM is very low power for battery operation supporting long lasting projects of 15+ years. It supports several features that reduce power consumption, including:

  1. The chosen electronic components inside are low power to start with.
  2. The network leaf nodes can be put in “Sleepy” mode, reducing the current consumption to a minimum (4.7 uA).
  3. The output power of the module is configurable, not to consume more power than needed during transmit.
  4. The TSCH, Time Synchronized Channel hopping, allows for the Mesh routers to go to sleep when there is no time slot for incoming or outgoing RF data packages.
  5. The RIIM Mesh Router can handle down to 118uA @ 3.3v average power consumption enabling all battery devices in the network to further extend the network coverage. For mesh routers in TSCH the battery lifetime is increased with more than 50%. This is accomplished by optimizing the sleeping pattern.
  6. The data processing that can be done by the customer in ICI can save substantial power. RIIM™ supports cloud computing which means that instead of sending all raw sensor reading data to the Cloud, the user can just send the interesting data, such as an alarm when a threshold is met.

You can read more about RIIM’s low power capabilities in the application notes below.

RIIM is also designed to have direct cloud connection using protocols such as IPv6, UDP, CoAP and DTLS. This eliminates the need for a dedicated border router and offers direct end-to-end IP packet communication with end-to-end security. Furthermore, RIIM can operate in a local mode where no internet connection is used.

A third use case is to extend RIIM with an edge gateway and then have external cloud connection from the gateway device. This is useful when the user intends to implement some edge-computational functions, thus decreasing latency. It can also be useful in case connection to the cloud is lost.

You can read more about connecting RIIM with an edge gateway in our application note below.

You can also visit Radiocrafts’ GitHub page for a sample code on how to connect a RIIM network to an edge computer.
