RIIM, Radiocrafts' Industrial IP Mesh

Become market leader in both price and performance competition with Sub-GHz mesh networking!

RIIM is a next-generation, license/subscription free, Industrial IoT wireless IP mesh network completely embedded in an RF module. The modern and unique features included in RIIM were specifically designed to solve major issues many LPWAN solutions struggle with today, including, scalability issues, lack of bandwidth, efficient two-way communication problems, and more. These features are essential for many applications such as smart irrigation, smart street lighting, EV charger communication, emergency lighting, wireless sensor networks, and more.

How RIIM Tackles Scalability Issues

A huge problem for LPWAN solutions today is the growing noise interference from global deployments of new and existing IoT devices and networks making it increasingly difficult to have scalable and reliable networks.

The RIIM network is designed for large node counts (1000 nodes) with it’s short transmit pulses and support for TSCH (time synchronized channel hopping).

Frequency hopping omits challenges with noise interference. A packet lost between two devices will be re-sent on a different channel in the next available time slot. This minimizes packet collisions drastically which is the largest problem for high node count networks.

A TSCH network has proven to have a reliability of 99.99%. 

Additionally, TSCH enables RIIM nodes to send up to 27 dBm output power thereby creating a sub 1-GHz mesh network with huge coverage.

RIIM High Power nodes support long range and up to 28 mesh hops allowing you to cover an area of up to 40 by 40 km squared in an urban environment. In a rural environment, the range is doubled.

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 has great coverage

How RIIM Tackles Lack of Bandwidth Issues

Existing LPWAN solutions today struggle with the vast amounts of data communication required by a modern smart city or industrial control application without breaking duty cycle limitations.

RIIM supports Adaptive Frequency Agility which allows for high-throughput networking by taking the allowed duty cycle in Europe from 1% to around 40%. This means that, for example, you can now go from 1 packet reaching the gateway every 4 seconds to 40 packets every 4 seconds!

This is a game-changer for applications that require higher throughput such as street lighting or smart irrigation!

On top of that, RIIM supports Mist computing to reduce bandwidth requirements and for fast responses to local events.

How RIIM Tackles Efficient 2-Way Communication Issues

RIIM supports efficient and symmetrical 2-way communication allowing for Over-The-Air Updates which makes RIIM a future-proofed solution.

This means that the user can upgrade their highly intelligent RIIM nodes in the field when the network is already deployed and fully operational.

The RIIM node’s intelligence comes from Radiocrafts’ ICI framework. An ICI application is always running on the module to tailor the module’s behavior to the customer’s unique requirements. In its simplest form, the ICI application is just configuring the radio network, the modules hardware interfaces, and defines when to read and write to those interfaces.

With the ICI and Over-The-Air Updates combo, you can create new sensor/actuator interfaces, new signal processing algorithms, and updated security patches. You can also keep the underlying RF system firmware current using RIIM Over-the-Air updates.


How RIIM Tackles Low Power Issues

The entire world is starting to adopt smart IoT solutions in a global effort to reduce our energy consumption and carbon footprint. Many applications which could be optimized by smart devices are located in hard-to-reach places or entail deploying hundreds of thousands of  sensors. These types of application require very low power battery operation which is often a lacking feature in LPWAN solutions today.

RIIM™ has a number of 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 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.

A RIIM™ node can last 10 years on a CR2772 (870 mAh capacity coin cell battery) while sending 12 bytes every hour, 24 hours per day.
