Wi-SUN Modules - Product Search Results | ROHM Semiconductor (1)

Wi-SUN is an abbreviation for Wireless Smart Utility Network, which is a next-generation wireless communication standard that has received a great deal of attention due to the adoption of this Wi-SUN in smart meters of Japan's leading electric power companies. In Japan, it is used in the 920MHz band called specific low power radio. The 920MHz band is a radio wave band that is unlikely to cause radio wave interference with existing radios, has low power consumption, and is capable of long-distance data communication. Compared to 2.4 GHz used by ZigBee and Bluetooth, the 920 MHz band has excellent radio wave wraparound characteristics. Therefore, it is possible to ensure stable communication even in the presence of walls and obstacles. It has already been used in the United States, China, South Korea, and Australia, and Europe is also considering opening regulations. It is believed that this will continue to expand the market.

      POINT 01　Certification under Japan’s Radio Law enables immediate use

      ROHM wireless communication modules have obtained certification under Japan’s Radio Law. And the pre-tuned wireless characteristics of the internal antenna allows customers to immediately begin development and evaluation without the need for complicated characteristics adjustment. Of course, Radio Law certification is not needed for the customer’s device.

      POINT 02　Wi-SUN certified, registered as a CTBU

      The BP35C0/BP35C0-J11 wireless communication modules have already obtained Wi-SUN certification. The BP35C2 USB dongle is also certified. The modules are also registered as CTBUs (Certified Test Bed Units) by the Wi-SUN Alliance, playing the role as reference units for Wi-SUN communication (Wi-SUN for ECHONET Lite Profile).

      Wi-SUN FAN Compatible Module

      Wi-SUN Modules - Product Search Results | ROHM Semiconductor (17)

      POINT 01　Supports multi-hop mesh networks

      Support for multi-hop communication (relay function) is provided by implementing RPL centered on RFC6550 (up to 24 hops), enabling bidirectional mesh-type communication. This makes it possible to automatically optimize the hop route - even in the event of communication failure due to newly constructed buildings or other surrounding obstacles - ensuring high reliability communication.
      A maximum of 1,000 simultaneous connections can be achieved by installing a FAN stack for large systems in the master gateway MCU (24 hops between repeaters and 64 terminals per repeater).
      The BP35C5 incorporates a Wi-SUN FAN stack in the internal memory that gives users the option of constructing a simple small-scale system connecting up to 100 devices to the gateway without an external MCU.

      POINT 02　Supports channel hopping

      Scheduled channel switching minimizes mutual interference even with increased communication traffic At the same time, it is possible configure a robust system strong against radio interference and noise while performing confidential communication.
      Under Japan’s Radio Law, there is a transmission time limit of only 6 minutes per hour when using one channel, but this can be extended to 12 minutes per hour utilizing multiple channels through channel hopping.

      POINT 03　Enables high data rates

      Wi-SUN FAN supports data rates of 50kbps and 150kbps.
      The BP35C5 also supports 300kbps.
      A high data rate allows data to be sent at high speed, reducing transmission time along with power consumption while suppressing mutual interference due to increased communication traffic.

      POINT 04　Wi-SUN FAN certified

      The BP35C5 is a Wi-SUN FAN certified module. Embedding the module allows users to develop Wi-SUN FAN-compatible products without the need to undergo the certification process. (Must be a Wi-SUN Alliance member to use the Wi-SUN logo) The moduled complies with radio laws in Japan and the US.
