Mioty is a low-power, wide-area network (LPWAN) protocol that has been designed for Industrial IoT applications. This LPWAN technology provides one of the most robust and efficient IoT connectivity solutions on the market. It operates using the unlicensed 868 MHz band in Europe and the 915 MHz band in the US. It supports a data rate of 512 bits/s and has a range of up to 20 km.

Mioty is based on the patented Telegram Splitting technology developed by Fraunhofer IIS. This technology divides a message into multiple sub-packets and transmits them at different times and frequencies.

With Telegram Splitting, MIOTY enables the lowest packet error rates, even in a crowded spectrum, and operates without interference by other networks. Since the air-time of these subpackets is much shorter than that of existing LPWANs, the chance of collisions with another message is very low. Even if 50% of sub-packets don’t make it to the gateway, the full message will be successfully reassembled. This allows for deep penetration in underground or hard-to-reach applications where interference would be an enormous problem for other LPWAN solutions.

Dramatically reduced on-air time combined with pseudo-randomness and superior channel coding provide unrivaled robustness against external interference while maximizing overall system capacity. MIOTY is the first and only technology to comply with the ETSI telegram splitting ultra-narrow band (TS-UNB) technical specification for low throughput networks (TS 103 357). 

TS-UNB, as defined by ETSI, splits the data packets to be transported in the data stream into small sub-packets at the sensor level. These sub-packets are then transmitted over fluctuating frequency and time. An algorithm in the base station permanently scans the spectrum for MIOTY subpackets and reassembles them into a complete message. 

Existing LPWAN solutions transmit data at a very low rate. In other words, the time it takes for a message to travel from a sensor to a base station (on-air time) is very long. The challenge for LPWANs operating in the license-free spectrum is that they are more prone to interference. In a license-free spectrum, LPWANs often co-exist and share limited spectrum resources. As the number of devices and data traffic increases, the spectrum becomes more crowded and interference problems become worse, causing the network to potentially lose a large amount of data. Additionally, to transmit sensor data at long distances, LPWANs must transmit this data at a long airtime rate which also contributes to more interference.

MIOTY aggregates millions of messages a day with a single base station, achieves an unmatched interference immunity, and transmits data with ultra-low power consumption. It is a powerful IoT solution for verticals such as Industrial IoT or Smart Cities, which need data transfer over 20 kilometers and data collection from moving devices at 120 km/h velocity. MIOTY is the only ETSI-compliant Massive IoT protocol to overcome the limitations of common LPWAN solutions.

Key Features of MOITY Technology

Minimum interference and maximum reliability: Mioty's patented Telegram Splitting technology enables the lowest packet error rates, even in a crowded spectrum, and operates without interference by other networks.

Maximum efficiency for worry-free operations: This protocol combined with battery recovery periods enables the application of smaller batteries. With a power consumption of 17.8 μWh (end-point, 868 MHz) per message, mioty makes battery life of 20+ years a reality.

Unmatched scalability and messaging capacity: mioty operates without interference through other networks or its own transmissions – enabling 1M+ devices per network and up to 1.5M messages per day. The Telegram Splitting features also allow for a highly scalable network for very high-density networks. A single network can have many hundreds of thousands of devices that can transmit up to 1.5 million data packets a day to a single gateway, with no loss of information even in hard-to-reach environments where there are a lot of physical obstructions and poor propagation properties.

Licence-free frequencies, private and flexible: mioty networks have a low barrier to entry, as this technology is compatible with most existing hardware. Each network is private, fully customized, and does not require frequency licenses.

Extensive Coverage: Thanks to the Telegram Splitting features, MIOTY also supports extensive range coverage of over 20 km Line-of-Sight. Additionally, all you need is one or a few gateways and you will be able to cover enormous, kilometer-long environments, such as, factories, large building complexes, mining and oil fields, and much more. With a flexible gateway, a network can be deployed in hard-to-reach, hidden, and noisy environments that were previously not viable using other LPWAN technologies.

Ultra-Low-Power Consumption: Optimized for power efficiency, the MIOTY protocol has the longest sensor battery life of up to 20 years.  Thanks to the Telegram Splitting technology, the sub-packets sent from the sensors to the gateway have very short airtime. This allows for a very low power battery operation. MIOTY has the longest battery life of any other existing LPWAN technology which makes it possible to have massive networks in hard-to-reach, noisy environments.

Exceptional Mobile Connectivity: Unlike traditional LPWAN technologies, which are limited in mobility, MIOTY allows you to collect data from sensors traveling up to 120 km/h velocity, unlocking a wide array of connected worker and fleet management applications.

Quality of Service: MIOTY is purpose-built to withstand heavy co-channel interference in the congested license-free spectrum, offering unmatched robustness. It is designed for demanding industrial applications and delivers carrier-grade reliability over challenging topology and through metal, rebar obstructions. Deep indoor penetration also secures consistent connectivity in the most hostile environments.

Private gateway: The MIOTY network is a private network which means you do not need to pay for monthly license or subscription fees as you would with a public network. All you need is one or a few private gateways to cover vast areas of up to several kilometers in demanding and noisy environments.
