New technology ・ Implemented router function in LTE communication module-Miniaturization of IoT devices and overwhelming low price. Developed a compact router equipped with new technology and an embedded LTE communication module ~

Amunimo Co., Ltd. (Headquarters: Musashino City, Tokyo, President: Chiharu Nakabayashi, hereafter Amunimo) is a new technology that implements a VPN-compatible router function on the processor of the communication module for LTE communication mounted on IoT devices, etc. Was developed.

By using the technology developed this time, it will be possible to operate various types of IoT devices only with the CPU of the communication module, and it will be possible to easily develop small and inexpensive devices. Also, when incorporating a communication module into an industrial device, it is possible to incorporate it with a simple implementation without developing a program to control communication on the industrial device side.

The technology developed by Amnimo this time is to implement the router function and the function to control the peripheral device interface, which were often implemented in the processor installed separately from the communication module, on the communication module side. It is possible to realize the functions required as an IoT device without installing the CPU of. By using this technology, it will be possible to manufacture IoT devices equipped with interfaces for various peripheral devices such as Ethernet ports, serial communications, DI / DO ports, and analog I / O ports in a smaller size and at lower cost. increase.

Equipment configuration with new technology

Amunimo has started developing a compact router equipped with an Ethernet interface as the first step of an IoT device with such a simple configuration.

This device is also equipped with Amunimo's proprietary power supply backup mechanism and multiple SIM card switching control functions, and will be provided as a small and inexpensive industrial router that enables highly reliable operation. is. Release is scheduled for the first half of 2022. In addition to being able to connect to various industrial equipment for remote monitoring, it is also suitable for replacing existing 3G communication terminals and ISDN communication terminals.

[Characteristics of compact router]

By installing a power pack-up mechanism, it can continue to operate for several tens of seconds even after the external power supply is cut off. In addition to suppressing memory crashes by completing the processing during writing, it is possible to promptly investigate the cause of the failure by notifying the maintainer.

It is possible to install multiple SIM cards, and it is possible to switch networks and restore communication in a short time in the event of a communication carrier failure.

It is equipped with a built-in antenna, and LTE communication can be used without installing an external antenna. (A coaxial connector for an external antenna is also installed)

You can build a network between multiple bases and realize VPN connection with highly secure IPSec.

It has strong durability against memory errors.

By linking with the device management system, which is a cloud service provided by Amunimo, various maintenance and operation tasks can be performed via the cloud, greatly reducing the burden on the operator. For example, it is possible to perform operations such as firmware update after installation in the field, change of setting contents, log collection for trouble analysis, and data transfer for failure replacement via the cloud.

Based on the device design developed this time, Amunimo plans to provide custom support to meet customer needs, such as devices equipped with serial communication ports and devices equipped with DI / DO ports as interfaces for peripheral devices. increase.

In addition, we plan to provide a communication module that implements this technology in 2022 for embedded use in industrial equipment. In the past, when incorporating an LTE communication module into industrial equipment, it was necessary to implement control related to communication activation, and it was necessary to implement extremely complicated processing, including processing when an error occurred. Since these functions are mounted on the module side of the communication module provided by Amunimo, it is possible to significantly reduce the man-hours for developing control functions on the industrial equipment side.
