    A Comprehensive Exploration of Voice Telecommunications, Standards, and Analog Modulation Techniques Week 1 DQs DQ 1 Do some research on the history of the telephone, telephony, and voice telecommunications. The ERR this week have some interesting articles.... There have been a number of significant technological changes to the telephone service since the invention by Bell. The technology and service has evolved drastically in 100 years. Besides the actual invention of the telephone, describe one significant technical innovation in voice telephony prior to 1975. Detail the reasons for your choice. Why is your choice significant? What did it contribute to the industry and/or subscribers? This DQ is about regular two - way, home - phone - type VOICE telecommunications in the United States; Plain Old Telephone Service (POTS). It is not about data, television/radio broadcasting, or the internet. The telephone and telephone service. If you do not answer within this guideline, I will ask you to post a new answer. FYI...do not use VoIP as it falls outside the criteria. Some examples: the switchboard, loading coils, fiber optics, the tube, the transistor, undersea cable, carbon mic, dial and touch tone, one piece handset, etc.... Include a reference with the post. My choice for the week 1 discussion question is the implementation of the world's first mobile telephone. Telephone is one of the milestones in the history of telecommunications. This has helped a lot in terms of communicating with people at home, office, business, and other distant places. But telephone , as we all know , is not portable or transportable which means that it can only be used in one place. If inventors were just satisfied with what telephone can do, it must have already phased itself out with the other telecommunication devices. This can be related to the development of the computers that we are using today. Before, computers are just driven by mechanical parts and tubes which move in coordination with each other to perform addition and subtraction. If computers were not developed to something better, we definitely could not post comments of Facebook, follow someone on Twitter, do video
