Localization has been mainly an optional feature of cellular networks since they have been designed for communication and many location-based services have used GPS to provide more functionalities like navigation, rescue and many more. GPS gets outstanding accuracy in outdoor environments, but its performance drastically degrades in indoor settings since the GPS signals hardly go through walls. However, most human activities are concentrated in indoor environments and location-based services cannot be carried out successfully by GPS. To overcome this limitation, wireless protocols are appealing to fulfill V

This paper addresses the use of channel state information (CSI) for Long Term Evolution (LTE) signal fingerprinting localization. In particular, the paper proposes a novel CSI-based signal fingerprinting approach, where fingerprints are descriptors of the "shape" of the channel frequency response (CFR) calculated on CSI vectors, rather than direct CSI vectors. Experiments have been carried out to prove the feasibility and the effectiveness of the proposed method and to study the impact on the localization performance of (i) the bandwidth of the available LTE signal and (ii) the availability of more LTE signals transmitted by different eNodeB (cell diversity). Comparisons with other signal fingerprinting approaches, such as the ones based on received signal strength indicator or reference signal received power, clearly show that using LTE CSI, and in particular, descriptors as fingerprints, can bring relevant performance improvement.

“…Bo et al [16] carried out a research on the impact of the existing positioning technology in LTE and proposed two approaches based on the reference signal time difference (RSTD) in the Observed Time Difference of Arrival (OTDOA) together with UE receiving time subtracting transmitting time (UE Rx-Tx). Liu et al [17] proposed locating users based on C-RAN using Time Difference of Arrival (TDOA) of Sounding Reference Signals (SRSs) from different antennas. He et al [18] worked on the CPRI protocol to achieve a low-latency compression scheme of LTE downlink signal based on a clustering algorithm to reduce the required CPRI transmission bandwidth in C-RAN.…”

Fourth-Generation (4G) mobile networks are based on Long-Term Evolution (LTE) technologies and are being deployed worldwide, while research on further evolution towards the Fifth Generation (5G) has been recently initiated. 5G will be featured with advanced network infrastructure sharing capabilities among different operators. Therefore, an open-source implementation of 4G/5G networks with this capability is crucial to enable early research in this area. The main contribution of this paper is the design and implementation of such a 4G/5G open-source testbed to investigate multioperator infrastructure sharing capabilities executed in virtual architectures. The proposed design and implementation enable the virtualization and sharing of some of the components of the LTE architecture. A testbed has been implemented and validated with intensive empirical experiments conducted to validate the suitability of virtualizing LTE components in virtual infrastructures (i.e., infrastructures with multitenancy sharing capabilities). The impact of the proposed technologies can lead to significant saving of both capital and operational costs for mobile telecommunication operators.
