Abstract:The current 4G network has been widely used by people,not only for human-to-human communication,but also for theInternet of Thing(IoT),and promotes the rapid development of related technologies to meet the needs of the future IoT applications.At present,the demand for Machine Type Communication(MTC)has led to a variety of communication technologies with diverseservice requirements to achieve the modern IoT version. However,the existing IoT communication technologies are faced with manychallenges,such as a large number of node connections,poor security and privacy,and the corresponding standard formulation andother issues. Besides,the 4G network has a poor ability to optimize the IoT due to its design limitations. With the maturing of 5G networktechnology,the 5G network-based IoT will achieve even greater performance improvements,including enhancing the operating capacityof cellular network,improving the IoT security and network challenge capabilities. This paper mainly introduces the latest communicationtechnologies for 5G IoT research and the main research trends and challenges of 5G IoT.
Keywords:5G network;internet of things communication technology(IoT);5G internet of things(5G IoT)
