The development path of the Internet of Things (IoT) is connection – perception – intelligence. Currently, we are in the first stage of IoT development, which is characterized by the rapid growth of IoT connections. By 2018, the number of global IoT connections is expected to exceed the number of mobile phone connections. First Stage … Read more
Abstract:The random access process, as an important procedure for achieving UE initial access and uplink synchronization, has been simplified and modified in NB-IoT based on the LTE system. By comparing with the random access process in the LTE system, an in-depth analysis of the currently supported contention-based random access process in NB-IoT is conducted, and … Read more
Abstract: The adoption of the Discontinuous Reception (DRX) mechanism is an important means for mobile terminals to reduce power consumption. In the NB-IoT system, the low speed and low frequency of services require terminals to have extremely low power consumption. Therefore, it has made corresponding modifications to the discontinuous reception mechanism and introduced the Enhanced … Read more
