G105/ G115

Products Introduction：

The G105/G115 module is the next generation of the G100 series product. Continuing NTT’s success in the field, it is easy to integrate GSM/GPRS modules for all industrial m2m applications.
The robust design and high tolerance of temperature make the G105/G115 the ideal platform for all kind of environments.
G105/G115 features an application development platform using Java technology. The Java virtual machine provides a powerful and easy-to-use development tool-chain and a rich application programming interface (API), which allows developer to create and manage various of wireless applications, such as fleet management or asset tracking. It significantly shortens the development cycle and makes the wireless application easy-to-maintain.
All NTT modules support FOTA (Firmware update Over-the-Air). By using RedBend’s vCurrent® agent, a proven and battle-tested technology powering hundreds of millions of cellular handsets world-wide, NTT is able to update its products by transmitting only a delta file, which represents the difference between one firmware version and another.
As a part of NTT’s corporate policy of environmental protection, NTT products comply to the RoHS (Restriction of Hazardous Substances) directive of the European Union.
