YateBTS allows anyone with a Linux distro to run their own GSM base station. Run YateBTS with USRP N210 or bladeRF x40/x115 Hopefully this tutorial will let you skip straight to the right SDR/base station pair and avoid some of the pain (and cost). Tried using the bladeRF x40 for srsLTE as srsLTE mentioned “bladeRF support”, but to no avail.Ended up having to buy the bladeRF x40 (older model) and use an older FPGA image to get devices to connect. Had multiple issues due to YateBTS writing their own radio driver instead of using the official bladeRF libraries. Tried to get the bladeRF 2.0 xA4 working with YateBTS because it mentioned it was supported.Spent a while going through commit logs to find an old working revision that supported UHD. Tried to get the USRP N210’s working with YateBTS latest checkout only to realize that they dropped support for the UHD driver.It could in theory work with other clock rates by performing resampling, but it does not do this. Spent a month trying to get these to work only to realize that srsLTE needs an SDR with a base clock that is a multiple of 1.92MHz (100MHz is not). Bought two USRP N210’s to setup srsLTE.Here’s a list of the main issues we encountered: Well every step along the way revealed some obscure software or hardware incompatibility that left us having try out many different configurations. So why didn’t we just stick with one SDR? These are both open source and their code is relatively easy to compile and hack on. Here are the SDRs we purchased (keep reading, you don’t need all of these): Nameįor the base stations we chose YateBTS for GSM and srsLTE for LTE. SDRs & Softwareįor our SDRs we used four different kinds across two base station implementations when trying to get our testbed working properly. With the disclaimers out of the way, lets dive in. Please still exercise caution to minimize risk to you and those around you and don’t use this for malicious purposes. When it comes to SDRs, rules or not, the genie is out of the bottle and laws won’t stop everyone.
