Opportunities and challenges of wireless networks in the era of mobile big data

With the rapid development of information and communication technologies such as mobile Internet, cloud computing, and the Internet of Things, the information society has stepped into the networked big data era. Smart terminals, widely applied in everyday life, are driving the explosive demands of wireless data services. In the era of mobile big data, wireless networks face with many challenges owing to the specific characteristics of big data such as high volume, variety, and non-uniform distribution in the time and space domains. And new approaches are required to address these new challenges. On the one hand, new spectrum technology, transmission technology, and intelligent networking offer promising evolution directions. On the other hand, mining the information contained in the low-density mobile big data, could be a new way to optimize current wireless networks. Data mining theory incorporated with mobile Internet can be applied in a wireless network to realize flexible networking, optimization of radio resource configuration, and green communication.
