Zhu Dianguo (right), Sensus Asia Pacific Strategic Account Director, said that smart meter networks must be specific. Left is Garry Cox, executive vice president of Sensus Asia Pacific Strategic Customer Group.
Zhu Dianguo, strategic customer director of Sensus Asia Pacific, believes that instrumentation is an important infrastructure, and the competent authority cannot accept data leakage. Therefore, if the instrument has joined the communication capability, the network is best to use Dedicated, and the technology it uses should have universality and can adapt to various environments.
Zhu Dianguo further explained that the communication technology used with smart meters can best be applied to high-density cities and inaccessible suburbs at the same time because the owners of smart meters do not necessarily have the ability to maintain heterogeneous networks. For example, a power company is an expert in power generation or distribution, but communication is not its specialty. If different network technologies are used in different regions, it will be a major obstacle to power company maintenance personnel.
On the other hand, the special nature of the network spectrum is also a major focus. Zhu Dianguo explained that if smart meters use unlicensed spectrum, such as Wi-Fi and other wireless technologies, they will encounter many interference signals. If exclusive spectrum is used, the possibility of interference will be relatively low. The FlexNet system has a frequency range of 200 MHz to 1,000 MHz. Its physical penetration capability makes it easy to penetrate even the thick walls of the Old Town in the UK.
However, this system is different from the concept of a general mesh network (Mesh). FlexNet is similar to the concept of a cellular network and uses direct connection to communicate. Data transmission does not require a repeater or an access point (Access). Point) to ensure the reliability of the data. In addition, the data is not relayed through the relay point, and there is no problem of data loss or transmission delay.
In addition to the strong reliability of network communication, FlexNet can also transmit Event information and even send out alarms to make Wisdom instruments more widely available.
