Video Description

In this video, I give an overview of a custom 2G/"EDGE" GSM cellular base station I set up using a Nuand BladeRF x40 full-duplex SDR, along with the open-source "YateBTS" software. After associating some SIM cards with the BTS software, I was able to get 3 old GSM cell phones connected to the network, with everything functional including calls, SMS, and even "EDGE" GPRS cellular data! For those who are interested in seeing the full software setup process, that video can be found here: https://youtu.be/1TdEOJeI-W4 An excellent guide for setting up OpenBTS with the URAN-1 by @BackSlashYT can be found here: https://www.youtube.com/playlist?list=PLbg31zdZbjfuf8xaUbaS2AhUMmSF_u_b7 SIM card programming/reading software: https://dosdude1.com/files/cellular/GRSIMWrite-software.zip YateBTS source and BladeRF FPGA content: https://nuand.com/downloads/yate-rc-2.tar.gz YateBTS with BladeRF guide: https://github.com/Nuand/bladeRF/wiki/Setting-up-Yate-and-YateBTS-with-the-bladeRF 0:00 Intro 4:44 Reading and associating SIM cards 9:33 Connecting phones to base station 11:32 Call test 12:46 SMS testing 13:37 GPRS data testing
