Rohm begins Internet sales of general-purpose Wi-SUN module

Flying well in energy saving, rapid spread of next-generation wireless communication

January 7, 2015

Rohm Co., Ltd. (Headquarters: Kyoto City) is a general-purpose wireless communication module

"Wireless Smart Utility Network" compliant with the international wireless communication standard

"Wi-SUN" (Wireless Smart Utility Network) that is ideal for constructing a smart community

including M2M, IoT, BP35A1 "mass production and Internet sales began.

Since "BP 35 A 1" began sample shipping from April 2014, it has received radio wave law certiﬁcation

and has optimum ﬁrmware for HEMS, and it has been well received as it can easily realize Wi-SUN

communication to any device It is.

We are now ready for the establishment of a mass production line with a scale of 30,000 pieces per

month and documentation and ﬁrmware necessary for Internet sales.

In response to this, from January 2015, we will start selling the Internet on the Wi-SUN module (standard retail price: 7,500

yen / piece) and various evaluation boards with three companies, Earls Components, chip one stop and core staﬀ . Internet

sales of general-purpose Wi-SUN module will be the ﬁrst industry the industry . And all the information necessary for

realizing Wi - SUN communication with BP35A1 is completed on the homepage, anyone can easily use Wi - SUN.

ROHM will continue to develop wireless communication modules that enable anyone to easily establish communication

environments for smart communities, M2M, and IoT markets.

※ As of January 7th Rohm survey

In recent years, consciousness of energy conservation has been increasing in all ﬁelds, and in order to use various infrastructure

eﬃciently, a smart community that utilizes a monitoring, control and management system has attracted attention.

Under these circumstances, promotion of "Wi-SUN" is being promoted as an international wireless communication standard

most suitable for constructing a smart community.

In Japan, Wi-SUN is equivalent to 920 MHz band called a speciﬁc low power radio, and because of its advantages of low power

consumption and long communication distance compared with wireless LAN (Wi-Fi), Smart-Meter and Transport Infrastructure

Smart Besides the community, it is regarded as most suitable for the M2M and IoT markets. Scenes where Wi - SUN can play

an active role, such as decision of adoption of electric power company 's Wi - SUN and' large - scale HEMS infrastructure

development project 'promoted by the Ministry of Economy, Trade and Industry, are increasing, and expectations are increasing

for future popularization.

ROHM pioneered the development of the Wi-SUN module with Wi-SUN Alliance certiﬁed product, a group company Lapis

Semiconductor's wireless communication LSI "ML 7396B", against the movement of these markets across the entire industry I

am going.

News Release of April 2014

developed the optimal "Wi-SUN" correspondence of the general-purpose wireless communication module to the industry's ﬁrst

smart community-building than

1. Equipped with optimum ﬁrmware for HEMS

By adopting a 32-bit high power microcomputer, this module was able to mount ﬁrmware suitable for HEMS for Wi-SUN. We are

also preparing method B (ZigBee stack) conforming to TTC standard JJ - 300.10, and it is possible to meet a wide range of user

needs.

2. Easy introduction of wireless functions with all-in-one module Easy introduction

becomes possible because high-frequency design becomes unnecessary because the radio wave law of speciﬁed low power radio

(920 MHz band) certiﬁcation in Japan has been acquired and the antenna is built in. Moreover, since it has the UART interface, it

is versatile with the ﬁrmware, making it a very easy-to-use module.

3. Lapis Semiconductor's ML7396B is adopted to achieve the industry's top class reception sensitivity The industry's

top class receiver sensitivity

of -103 dBm (100 kbps, BER <0.1%) is realized for the most important reception sensitivity of the wireless characteristics. It

enables even higher communication quality among speciﬁc low-power radios that are easy to connect.

<Term Explanation>
M2M (Machine to Machine) / IoT (Internet of Things) 
M2M is a machine-to-machine system in which electronic devices and electronic devices communicate with each other, not
limited to PCs and servers.  
IoT is said to be an Internet thing in Japan, meaning that electronic equipment other than IT equipment is connected to the
Internet.  
These two are expected to create not only domestic appliances but also large markets for communication in various ﬁelds such
as medical healthcare, infrastructure, and industrial equipment.
