Simplest RF 4G Signal Booster / amplifier Experiment 20 Mhz Crystal Oscillator
123#homeMade #DIY #project i am working on #HowTo boost / #amplify RF 4G signal - this is one component test using active crystal oscillator / #resonator with frequency rated at 20 Mhz. Powered by 5 Volt USB power supply.
One significant observation I've seen is that the signal around 10 Mhz and above seems to have effect on the 4G Signal amplification. This test is done on HuaWei #WiFi 4G modem run on #DiGi #Internet network cell service provider.
The environment i am testing is well covered within the 4G signal area however the reception from the #modem is very poor because it is placed in the house where it is block by many things. So i thought i could re-amplify (repeat) or help to repeat that signal and provide a significant improvement to my internet speed. The average speed without the booster is around 2 Mbps or less
Using the 20 Mhz crystal oscillator it can drive the speed at minimum of 7 Mbps up to maximum of 15 Mbps and ocassionally up to 25 Mbps. As you can see the speed after the amplification is quite fast.
I have rebuild a new antenna for the HuaWei modem using soft drink can - it works quite well.
