Below is a tutorial I used to install all the software needed to run the BladeRF. I love this thing, no complaints, it's been working like a dream! You can do the same with a USRP or LimeSDR(when they come out), you just need something that's full duplex. Another downside about using a SIP service is that all outgoing calls will have a different phone number which makes call backs difficult.įor my transceiver I'm using a BladeRF X115. When you connect to the base station your phone will be assigned a new phone number and will only be able to communicate with other devices on the network. One limitation about using YateBTS is that any device that connects to the network will only exist in that network unless you configure outgoing SIP. I'm using my Yard Stick One for that task. You just need to have another radio running on the same band as your base station's down link transmitting your call sign every 10 min in CW or RTTY. Another advantage of configuring a base station to be unencrypted is that it keeps it legal for hams to broadcast on the 900mhz HAM band :3. I had to configure my phone manually to make it connect. Seams like my phone preferred LTE over GSM so go figure lol. I like to think of this as being downgrade attack but TBH it was a struggle for me to make my cell authenticate with my base station. One advantage to GSM is for the attacker is how you can set the base station to communicate everything in clear text. It's old tech but it's still supported by most if not all modern cell phones. GSM and GPRS are legacy now due to LTE (Long-Term Evelution) becoming the slandered for all cell phones. This is how you get your Internet on a 2g or 3g cell network. GPRS ( General Packet Radio Service) is a packet oriented mobile data service.GSM (Global System for Mobile Communications) in short this is the technology being used to transmit and receive voice and text.Yate and YateBTS is a software implementation of a GSM/GPRS radio access network that has the capability to convert GSM traffic to VoIP.
