Now we're going to install Yate and YateBTS, two open source softwares that will make us able to create the BTS itself. IMPORTANT Make sure you have these exact versions of the firmware and the FPGA, other versions might not work in our setup. Start the bladeRF-cli utility and issue the version command: Next, install a few dependecies we're gonna need soon:Īt this point, you should already be able to interact with the BladeRF, plug it into one of the USB ports of the RPI, dmesg should be telling you something like: Let's start by installing the latest Raspbian image to the micrsd card ( use the "lite" one, no need for UI ) ), boot the RPI, configure either the WiFi or ethernet and so forth, at the end of this process you should be able to SSH into the RPI. An USB battery pack ( I'm using a 26800mAh Anker Astro E7 ).A Raspberry Pi 3 ( model 2 and below are too slow ).Two Quad-band Cellular Duck Antennas SMA.In order to build your BTS you'll need the following hardware: I'm not writing this post to help script kiddies breaking the law, my point is that GSM is broken by design and it's about time vendors do something about it considering how much we're paying for their services. yes, with some (relatively) cheap electronic equipment you can basically build something very similar to what the governments are using from years to perform GSM interception. In this blog post I'm going to explain how to create a portable GSM BTS which can be used either to create a private ( and vendor free! ) GSM network or for GSM active tapping/interception/hijacking . In contrast, the Planar Disk is almost free and it performs quite well in an indoor setting.The last week I've been visiting my friend and colleque Ziggy in Tel Aviv which gave me something I've been waiting for almost a year, a brand new BladeRF x40, a low-cost USB 3.0 Software Defined Radio working in full-duplex, meaning that it can transmit and receive at the same time ( while for instance the HackRF is only half-duplex ). Just because an antenna "is sold" does not mean its good or even marginal. Please verify your dongle is working with a good antenna before complaining that you cannot receive something. Here is a great, broadband Planar Disk Antenna that outperforms most commercial antennas of similar size for under $65-75 and can be built in a half hour or less by beginners with less than $10 in parts. See our wiki with tutorials and other resources including a Quick Start page to verify your dongle works. The rtl-sdr project page Source of the rtl-sdr driver software and hub for its continued development. Resources - Please read this first - before posting! Max sample rate: 3.2 MS/s (2.6 MS/s in practice).Frequency range : 24 - >1760 MHz (100 KHz - 24 MHz in direct sampling mode).Typical specs (some depend on specific tuner): All rtl-sdr compatible devices employ the RTL2832U as an ADC and USB controller, but different RF tuners may be used. "rtl-sdr" is a generic term for cheap USB digital TV (DVB-T) receivers that use the Realtek RTL2832U chipset, which can function as general purpose software defined radios (receive only). While originally dedicated just to the rtl-sdr project, relevant legal content related to general SDR, RF and similar projects is also welcomed.įeel free to ask questions but please check the wiki first.
