A 4G guided universal base station carrier interferometry enabled infrastructure

The fourth generation wireless system provides the key technologies for the upcoming era of ubiquitous computing. Major obstacles facing 4G wireless system deployment involve (i) the mobile device´s chipset for connecting to different frequencies and (ii) multi frequency base station units supporting various carrier frequencies communication. Some researchers have looked at the solutions for the first obstacle. Continuing on these efforts toward accommodating different radio interfaces with various carrier frequencies, a universal base station (UBS) with multi-carrier carrier interferometry (MC-CI) is introduced. The UBS customizes its radiation pattern by utilizing the principles of the (MC-CI) technology to match the mobile device´s chipset carrier frequency. The proposed approach provides a novel framework to design a universal soft cell allowing interoperability between different wireless networks. Simulation studies have been carried out to verify the effectiveness of the proposed approach.
