Fiber to the antenna: A step towards multimode radio architectures for 4G mobile broadband communications

During the evolution of mobile networks, reusability of network components has been always a main concern. At the same time, keeping operational and maintenance cost at reasonable levels is a major task. This paper presents and quantifies the advantages of using multimode remote radios capable of operating according to various standards (WCDMA, WiMAX and LTE) for resolving these challenges.
