Description:The sixth and last module “Smartphone & Mobile Network Project” focuses on methods and apps to analyze the components of smartphones and check the mobile network. In project 1, the Smartphone project, the status and components of both Android and iPhone smartphones are tested. Because the projects require for both Android and iPhone smartphones to be tested, the learner may need to borrow a smartphone (the type which you do not have) for a while to do the experiments, and after the project is done, erase the installed app(s) (and maybe recharge it) before returning the borrowed smartphone. In the Smartphone project, the smartphone types and the specs of the CPU, SoC, number of cores, memory types & sizes of each smartphone need to be reported and will be Peer Review evaluated. In project 2, the Mobile Network project, the details of the connected mobile network are to be observed. During the Mobile Network project, the learner will measure the PCI, RSSI, RSRP, RSRQ, RSSNR, ASU, and CQI values, and also find a location of where the largest number of Neighbor Base Stations, and how many were there, and report all details for Peer Review evaluation.
