For a Hackaday prize entry, [TegwynTwmffat] is building a cell phone signal repeater. This kind of gadget is commercially available, however the choices are either costly or, as with some units offered for $30 on DealExtreme, undoubtedly noncompliant with RF regulations. This job means to produce a cost-effective, hackable gadget that works appropriately as well as conforms to the ideal regulations.
The core of this system is a LimeSDR transceiver. This is a board we’ve seen before, as well as it has a few fascinating features. Basically, the core of the LimeSDR is a programmable RF transceiver with protection from 100kHz to 3.8GHz. There’s likewise on-chip signal processing as well as USB 3.0 bandwidth to get the signals to as well as from a computer.
Right now, [TegwynTwmffat]’s focus is getting his LimeSDR up as well as working as well as figuring out exactly how to set up a few radio blocks to do what is needed. There’s a fantastic update to the job that showcases Pothos, as well as so far [Tegwyn] has a full-duplex repeater working. This is fantastic work, as well as truly showcases the abilities of what software-defined radio can do.
