Research and Development of Customized Wireless Device Based on the Multimode Chip for Energy Internet Applications

The customized wireless devices play a key role in information exchanging for various electrical facilities. However, the development of the devices is hindered by diversity of interfaces (RS-232/485, Ethernet, USB, etc.), high cost, outdoor environment, etc. In this work, we proposed a ‘system on module’ solution to address above issues. We optimize and spare the storage space of baseband chip for embedded control system to replace the independent chips, which dramatically reduces the size, cost and power consumption of devices. Meanwhile, our SOM wireless devices can support multi-interfaces and thus realize ‘plug and play’. Moreover, our developed wireless devices allow multimode wireless communications including operator's wireless networks LTE FDD/TDD, UMTS, GSM and self-built LTE-G 1800MHz network. Last but not least, we can embedded positioning chip and the client of management system in the wireless devices for the sake of operation and maintenance.
