Silicon Labs FG25 Sub-GHz SoC Supports High Data Bandwidth of up to 3.6Mbps, Available for Smart Cities and Smart Meters
During our Works With 2022 Developer Conference, Silicon Labs announced our new flagship sub-Ghz SoC, the FG25, and today Silicon Labs is pleased to announce that it is generally available through Silicon Labs and distribution partners.
The FG25 is the ideal SoC (system on chip) for long-range, low-power transmissions, capable of broadcasting up to 3km with minimal data loss in dense, urban canyon environments when coupled with the Silicon Labs EFF01 Front End Module. It is also the first SoC in Silicon Labs’ portfolio to support the orthogonal frequency-division multiplexing (OFDM) modulations introduced in Wi-SUN Field Area Network (FAN) 1.1. OFDM supports high data bandwidth of up to 3.6Mbps. With the higher data rates, the FG25 SoC enables the large networks needed by smart cities where the nodes can number in the thousands.
Silicon Labs is also pleased to announce that Silicon Labs has been certified by the Wi-SUN Alliance for the PHY layer of the FAN 1.1 profile. Customers can leverage this certification to lower the burden placed on them as they design Wi-SUN FAN 1.1-complaint devices.
Landis+Gyr Adopts FG25 and Wi-SUN for Smart Meters
Up until now, Landis+Gyr had used FG12 SoC running their own proprietary stack, but because Wi-SUN is an open network, it offers increased interoperability and simplified development, meaning it can scale to match the massive size of a city. And while the FG12 helped Landis+Gyr drastically reduce the power consumption of their devices, it didn’t have the RAM needed for Wi-SUN and OFDM. By moving to the FG25 Wi-SUN SoC, Landis+Gyr not only increases the performance of their solution but also gives their customers a smooth Wi-SUN transition because the FG25 runs their proprietary stack as well. With both the MCU and transceiver on the same chip, the FG25 uses the same form factor as Landis+Gyr’s existing module, simplifying the development and design process to integrate the new SoC.
