Abstract

This paper presents a comparative study of different Multiple Input Multiple Output (MIMO) array architectures to realize high-capacity Point-to-Point (PtP) wireless links for potential use in future 6G backhauling applications. This study focuses on the 220-320 GHz band, defined by the new IEEE 802.15.3d standard. Both phased array and focal plane array architectures are studied, considering the link to operate in the radiative near-field. The theoretically achievable capacities are presented based on the channel matrix estimated in the radiative near-field and the application of Shannon’s capacity formula. It is found that capacities well above Tbps rates can theoretically be realized, even without the use of interference cancellation techniques.
