Integration of Wideband and Narrowband Communication in Power Wireless Private Network

Wireless communication technologies are well developed in recent years and are widely used in different applications. In the energy Internet of Things, cellular communication is the key to connect all the power devices in the world. For the consideration of reliable and security, TD-LTE based power wireless private network is already under construction in China. The power wireless private network is aiming to support current and future power services, both wideband services and narrowband services. The current power wireless private network with carrier frequency of 230 MHz is narrowband communication which is established by Potevio. In order to supporting both wideband and narrowband services in one system with limited changes on current network, we proposed a solution to integrate multiple narrowband devices in physical to realize the wideband services transmission.
