Cellular network performance is often viewed as primarily dominated by the radio technology. However, middleboxes such as DNS resolvers and omnipresent performance-enhancing proxies in the IP core of the operators' mobile networks can significantly impair a user's access despite being designed for the contrary. In addition, common roaming and network sharing agreements between mobile operators to extend their network coverage at minimum deployment cost — as well as innovative business models such as Mobile Virtual Network Operators (MVNOs) — can increase the complexity of cellular networks while potentially degrading the performance standards expected by mobile users and complicating their trust decisions.
