The VW3071 series wireless modulesare built on the top of Semtech's newest high performance LORA RF chip -SX1262, which with higher rf output power, high sensitivity, gives stable and reliable long linkage range. The advantage of LORA modulation has remarkable high sensitivity and thus helps to extend communication range.
VW3071 series modem built-in with a transparent data communication protocol.It also equipped with other enhanced protocol, for example, the point-point, point – multi points, and master-client, etc.It is allowed to change the operation modes on the field.Aside from the powerful LORA modulation, VW3071 series modem also have the GFSK setting enabled. When GFSK enabled, it can communicate with our other standard fsk/gfsk production line, for instance, the VW320A series modem.And, a wmbus-T1 receiver protocol is ready for VW3071 series. We can use this device as a handy usb wmbus receiver which will report the wmbus-T1 raw data.A user friendly PC program is provided to easy the parameter configuration.
