GreenWaves Technologies Produced a Prototype of a New Wireless Modem for the IoT
GREENWAVES Technologies just produced a prototype of a new wireless modem for the IoT.
It is implementing the GreenWaves LPWAN wireless modem dedicated to the high data rate LPWAN applications. This model includes a NUCLEO development board, a XILINX Zynq-7000 FPGA development board and an ATREB215-XPRO evaluation board instantiating an ATMEL AT86RF215 analog front-end.
The interface with the sensors and the board configuration are processed by the STM32 microprocessor on the NUCLEO board. The GreenOFDM digital modulation is implemented on the XILINX ZYNQ-7000 FPGA. The ATMEL AT86RF215 circuit is a full modem of the 802.15.4g standard from which GreenWaves only uses the OFDM front-end implementation. The GreenOFDM wireless modem running on the XILINX ZYNQ-7000 FPGA generates the IQ signals that are then sent via a serial link to the analog front-end of the ATMEL circuit.
This board prototype will allow GreenWaves Technologies to deploy high data rate low power communicating objects in an existing LPWAN network.
In a second phase, this board prototype will be integrated on one standalone board. It will be available to early adopters for prototyping communicating objects applications.
In a third phase, the FPGA will be replaced by an ASIC. This full GreenOFDM wireless modem will be manufactured and delivered to customers.
