Experts have suggested that using LTE Cat.M1, an LTE-based communication method for Internet of Things devices, and AWS IoT SiteWise can shorten the time required to build IoT services.

In the e4ds Mouser-sponsored webinar on February 24, Codeju CEO Jang Byeong-nam discussed 'AWS Cloud Service Design Using LTE Cat.M1'.

CEO Jang Byeong-nam said, "This is an opportunity for small and medium-sized enterprises and startups with limitations to advance overseas through globalization."

The webinar introduced Cat.M1 and explained the hardware configuration. It also covered a demo of implementing a service using Cat.M1 and AWS IoT SiteWise.

LTE Cat. M1 was introduced as having the following advantages: △Can be used even without communication infrastructure, △Can be used as a communication network even when there is no Wi-Fi nearby, △Can be installed in ultra-small devices, △Suitable for low-power devices, △Enhanced security, and △Low communication costs.

Major domestic IoT technologies include Cat.M1, LTE-M, LoRa, and NB-IoT. Cat.M1 has the coverage of an LTE network, but is a low-speed communication method with a maximum transmission speed of 300 Kbps.

Vodafone, a British mobile operator, was introduced.

CEO Jang said that GlobalSIM is advantageous for entering overseas markets because it can be used for roaming in over 180 countries, not just domestically, and that it has the advantage of not requiring separate device network authentication.

The Murata Cat.M1 used in the demo features the smallest size available, low power consumption, and long battery life.

Cat.M1 was introduced as being different from existing connectivity in that it is provided with all setups set up inside the modem.

Cat.M1 communication method provides an external interface and is used by connecting to the internal communication chip CPU. There are two AT commands and PPP communication methods.

AWS IoT SiteWise is a composed service that easily builds various services such as data collection, analysis, asset tracking, and asset management that are commonly used to build IoT services.

Ultimately, AWS IoT communication enables easy service implementation by using sources that are already built-in in the AT command format.

In the latter half of the lecture, a demo of implementing a service in conjunction with Cat.M1 and AWS IoT SiteWise and a real-life case of the Asung collaborative robot were introduced.
