Sigfox Communication Module

Sigfox Communication Module
We provide a two types of modules: a simple module with Sigfox only, able to meet the demands of dealing with complex operations from a straightforward implementation, and a composite module equipped with BLE, Wi-Fi, and GPS.
-
Feature 01
The world's smallest module
The world's smallest Sigfox Communication Module, supporting RCZ3 (a Japanese frequency).
-
Feature 02
Maintaining product life
The use of a temperature compensated crystal oscillator (TCXO) maintains a uniform permitted operating bandwidth frequency over the product's entire life.
-
Feature 03
High quality at a low price
We are jointly developing modules for Europe (RCZ1), North America (RCZ2), and Oceania (RCZ4), to provide high quality at a low price.

Benefits
Meter readers have to visit people's homes once a month to get the figures for providers to
record their sales. Up until now communications equipment like fixed line phones or mobile terminals were
used, but due to problems like communication costs or battery life they were unsuited for acquiring meter
data. The new wireless communications technology LPWA sends small packets of data with minimal power, reducing
battery consumption and making possible wide-area coverage. Sigfox is an implementation of LPWA that uses its
characteristics to reduce communications costs. KCCS began providing the service in Japan in February 2017,
working on progressively applying it to IoT devices. In this case we used Sigfox technology to achieve work
efficiency by notifying consumption amounts via smart meter Sigfox communications.
※LPWA = Low
Power Wide Area.
※Sigfox is an IoT network standard provided by the French company Sigfox.
※KCCS is the
abbreviation of KYOCERA Communication Systems Co., Ltd., the provider of Sigfox services in Japan.
