Abstract: The 4G wireless network standards are motivated to frequency reuse, where it will raise the system capacity and normalize the planning of radio networks. As the system capacity increases, the signal to noise (SNR) ratio will be degraded due to the interference in the cells. The present security will not suitable for the physical layer of Long Term Evolution (LTE) networks. The key characteristics of the channels of wireless networks are open and broadcasting. As these networks can be attacked easily through interference, signal jamming and eavesdropping. Hence the security issues in physical design will be considered as the critical issues in LTE networks. So, before discussing security issues, we should identify the threats and vulnerabilities raised in the low-level layer of wireless networks. Later in this paper, the secure schemes and other procedures will be explained where that can be adopted in the physical layer.
