Survey on Ultra Dense Networks for Next Generation Cellular Systems EE 359 Wireless Communications
Over the past decades, there has been a continuous growing demand for faster, safer, and more intelligent wireless networks. Requirements for next generation cellular networks include higher data rates and scalability, lower latency and energy consumption, and improved connectivity, reliability, and security. Many key enabling technologies have been proposed as solutions to meet these requirements, such as ultra densification, wireless software defined networking, massive MIMO, and millimeter wave technology [1] This survey will be focused on proposed changes in cellular architecture, specifically Ultra Dense Networks (UDNs) that aim at solving the challenges of future cellular networks.
