Wireless communication technology can provide stable and reliable communication for any application at any time, any place, and has huge technical advantages such as no channel construction, fast system deployment, flexible and convenient terminal layout, and strong system expansion capabilities. State Grid proposed that the pilot construction of terminal access networks also focus on the construction of LTE wireless networks.
