Huawei, China Unicom Shanghai and China Unicom Research Institute have teamed up to deploy a Cellular Internet of Things (CIoT) Pilot based on 4.5G LTE-Machine to Machine (LTE-M) in Shanghai, reports Telecompaper.com on July 13, 2015. China Unicom Shanghai has piloted Smart parking, which marks the beginning of actual commercial applications of LTE-M-based CIoT technologies.
Huawei says LTE-M, compared with LTE, is designed to increase in-depth coverage gain to up to 100-fold and the number of connections to over 1000-fold, while the power consumption of the device is only 10 percent. LTE-M requires 200KHz spectral resources and reuses existing network resources, which enable carriers to carry out rapid construction of LTE-M networks.
The Smart parking system piloted in Shanghai is a typical application of LTE-M. Parking stall detectors periodically collect data and report the status to the server through LTE-M. Drivers can search for available parking spots around the city at any time using a mobile app.
