Introduction: Arduino Cell Phone 4G Signal Booster / Repeater Part 1Living on an island in the middle of nowhere, mobile/cell phone reception can be rather intermittent and it seems that there is currently no reliable open source gadget that could help me solve this problem on my kind of budget.I do have the option of using 'cable phone' but being of a general 'Pirate' disposition I thought it would be a better idea to do all my phone calls, emails and data transactions by cell phone and save a whole bunch of dollars by not having to pay for land based line rental and broadband etc. Doing everything through my phone is a lot cheaper and still plenty quick enough to watch films and videos without any buffering.I actually tried buying an off the shelf repeater but it completely jammed my phone up and I started to get worried that it was going to damage it, so instead I opened it up to see how it worked - maybe I could repair it? Unfortunately none of the components could be identified and furthermore, it looked like it had been severely 'messed about with' at the factory. The soldering looked very poor and a large piece of metal swarf fell out of the opened case :( I did search on the Interweb for tutorials and information on how to build this kind of device but, unfortunately, there was only one single piece of information:https://www.instructables.com/id/4G-LTE-Home-Repeater-With-LimeSDR/I did actually re-create this instructable and, after 6 weeks constant toil, got it to work but decided to create a separate, simpler version, which is this one documented here!With absolutely no previous radio frequency (RF) experience, the challenge was to learn how a repeater works by playing around with a software defined radio (SDR) and then build one from scratch with the necessary hardware filters, amplifiers and controls.The 'RepeaterDuino' / 'RepeatDuino' / 'RFBoostDuino' / 'RFRepeatDuino' / 'OpenRFRepeater' / 'PeoplesRepeater' / 'PirateRepeater' is born!Step 1: How It WorksThe cell phone base station signals are constantly being transmitted from one or more masts owned by the phone company. In my case, I can only reliably receive the 4G signal if I stand on a roof or raise my phone up a pole like a flag so an external antenna mounted 20 feet up a pole is necessary. The external antenna receives the good quality signal and sends it down a shielded cable to a filter which very accurately stops everything except a very small slice of frequencies. For my phone, these frequencies are centered around 806 MHz and have a spread, or bandwidth, of 30 MHz.The signal then goes into a LNA (Low Noise Amplifier) which does a fair bit of amplification at low power and .... as it says on the tin, very low noise aberrations. It's much more efficient to 'cascade' the amplifiers rather than try and do everything with one device.Next is the Variable Gain Amplifier, or VGA, which does most of the grunt work and has the ability to be controlled by a microprocessor by means of very simple SPI code. The gain needs to be controlled as sometimes the base station signal can be quite strong and we don't want to damage our phone or create a feedback loop between the two antennae. The antennae have to be spaced well apart or separated by thick walls or metal sheeting.Simultaneously, the signal comes out of the BPF and routes into an RSSI (Received Signal Strength Indicator) which provides an analogue signal ie a DC voltage to the micro controller, which can turn down the VGA if the signal is too strong. At the moment, control of the VGA is manual by means of a slide potentiometer.The amplified signal goes out of the VGA into a plate antenna which is located inside the building and transmits the signal to the cell phone.Step 2: Video DemonstarionThis video above shows all the main components of the repeater, which is demonstrated using my own phone and a spectrum analyser, which has a small 'whip' antenna located right next to the plate antenna. The spectrum analys
