e idea of the first cellular network was brainstormed in 1947. It was intended to be used for military purposes as a way of supplying troops with more advanced forms of communications. From 1947 till about 1979 several different forms of broadcasting technology emerged. The United States began to develop the AMPS (Advanced Mobile Phone Service) network‚ while European countries were developing their own forms of communication. 1.2 History of GSM Technology Europeans quickly realized the disadvantages

INTERPRETATION OF RESULTS In the first experiment of the course‚ there are three objectives that are needed to be proven through different materials and procedures. The first is objective A‚ where we are to identify the values of the resistance and capacitance by measuring and computing. There are no problems about this part since the values are in agreement; meaning it only got a little amount of percent error. Next‚ objective B wants us to familiarize with the oscilloscope by setting it up to
