Furthermore, the RF detector has a broadband response and the measured time response for 5G FR2 band n262 (48 GHz) is less than 100 ns, as presented in Fig. 30. If the modulation BW for 5G signal is higher (such as 1–2 GHz), the time response can be adjusted through post-detection low-pass RC filters.
The channel model used in the experiment was a 28 GHz frequency band channel model using the 3GPP Propagation Model (RAN1, 2022). Additionally, channel interference between base stations was not considered as it was not supported by the test bed. The 5G simulation scenario was set up as a 3D-urban macro (UMa). We placed the cells in a 2 by 3 grid.
The ET system incorporates delay calibration for the modem generated envelope signal, using the transceiver to observe RF signals. In current 5G mobile devices, two spaced RF signals are employed, and their peaks are equalized for delay calibration, as outlined in paper .
Despite the substantial benefits that 5G technology offers, the vehicular network environment also faces persistent threats, among which the false base station attacks (Marojevic, 2018) must be dealt with first. The 3GPP TS 33.809 focuses on major issues and solutions concerning rogue base stations in the 5G environment.
Emulating real-world 5G conditions, we implement a functional split in the 5G base station and deploy the False Base Station Detection Function (FDF) as a 5G NF (Network Function) within the CU
