With the new energy economy trend of innovation and smart communication penetrating into M2M industry, Quectel wireless solutions designs the solution that integrates wireless communication technology with smart grid, which both meet the wireless communication needs and make the energy supply smart, secure, sustainable and reliable.
Cellular modules play an important role in the whole system of smart grid, which is the bridge between sensor and base station, as well as the environment of smart meter deployment is varied. So, cellular modules need to be solid and reliable year in and year out. Quectel modules address the requirements mentioned above through:
Reliable data connection in hazard condition
Smart meters are equipped in the varied temperatures from the lowest -40℃ to the highest +85℃, or in the area where there is big temperature difference between day and night. So, the high reliability of GSM/GPRS, UMTS/HSPA(+) and GNSS modules is of prime important. With the advanced product design standard, optimized software algorithm, and amounts of MTBF and RF testing, Quectel modules can performance well even in the areas of poor signal reception.
Over-the-air updates and automated warning system
Over-the-air software patches and automated warning system have increased security for the field staff, who are no longer.
Secure data transmission
Security mechanisms for data transmission have been taken to guarantee the data transmission secure in the cellular wireless network. Quectel modules ensure secure, mission-critical data performance with support for secure layer (SSL) and jamming detection, static IP addresses, a dedicated APN, secure SIM authentication and PIN code.
Global network coverage
Quectel modules can get wireless connectivity anywhere a mobile phone works, with interfaces that support all major cellular networks.
