The network modules provided by DORJI are designed for Automatic Meter Reading and wireless sensor network applications. Considering the rigid requirements for power consumption in different networks, DORJI provides three categories of network modules for selection.

DRF1212D10x network modules are based on SX1212 from Semtech, which is known for its extra low power consumption. In receive mode the node module consumes about 2.8mA current which is very suitable for gas meter and water meter applications which need very long operation period without replacing battery.

DRF7020M13x modules use ADF7020-1 RFIC from ADI. This category is the earliest series of network modules released by DORJI and have been successfully utilized in many AMR networks in China. DRF1212D10x network modules adopt the same networking protocol as DRF7020M13x's because of the mature protocol and application platform. Comparing to other two categories, DRF7020M13x network modules make a compromising between power consumption and communication distance.

With the release of SI1000 by Silicon labs, more compact and higher power network modules became possible. DORJI is the first company who built network applications on SI1000 and has finished the engineering stage of new products. At present the DRF1000D20x series modules are under field testing and will be launched on Jan, 2011. Please check the product news for newest information.
