Bag phone to Smart Phone ( Conception, to Design, to Implemetation and Assignment

Bag phone to Smart Phone ( Conception, to Design, to Implemetation and on to Operation then Decommission. CDIOD.) - Assignment Example Consequently, the paper discusses the impact of various design, and the manufacturing techniques that can be used in the production of mobile phones. Conception. A cellular phone is a wireless device that people use to communicate. Its Technology is based on the technology of radio that was developed since 1940’s. In 1843, Michael Faraday researched if electricity could be conducted via space. His study led to the development of cell phone. In 1865, Doctor Mahlon Loomis communicated first through the wireless atmosphere. He developed the idea of receiving and transmitting information via space as a conductor (Androulidakis, 2012 ). He was later awarded 50,000 for his study. The conception of cell phones is traced to the creation and innovation of police cars, taxi cabs, and other service motor cars whereby the radios enabled the police officers and taxi cabs to communicate with each other or a with the central station. Communication technology of cell phones can be traced to i ndividuals that had special radios patched on a phone line through a live operator when making a phone call. Police officers from Swedish used the first cell phone in 1946. The technology was linked to the network of a telephone and was unique of radio technology. The cell phone was less practical because it could make six phone calls before the battery of the car drained ( Bhowmik, 2008 ).. The modern mobile phone technology began when D.H. Ring created six sided cells for cell phones in 1947. Later on, an engineer for Bell Labs developed the idea of cell towers that would receive and transmit signals in 3 directions rather than two. However, despite the development of technologies, electronics and other technologies take years to mature. For example, the first cell phone’s electronics were developed in 1960. In 1967, the technology of mobile phone was available. However, the users had to station themselves within a single cell area. These regions that base stations serviced did not hand off phone calls from one station to the other. Despite users making calls, they were not able to make calls after attaining a certain range ( Goggin, 2006). A call hands-off system was developed by Amos Joel from Bell Labs in 1970. The technology enhanced un-dropped phone calls from one region to another. Even after developing the technology, in 1971 AT&T submitted a proposal to FCC for services of cellular. Approval took 10 years. In 1982, frequencies of 824-894 MHZ Band were allocated to Advanced Mobile Phone Service AMPS . In 1990, AMPS shifted from analog to digital service. Throughout the years, many technologies that led to the development of mobile phones existed. Mostly, the phones were available on vehicles because of large battery requirements. For example, the Mobile Telephone System that was developed by Erikson in 1950 was available in Sweden. Unluckily, it weighed over twenty pounds, which is ineffective when compared to today’s portable devices. 1 st Generation Cell Phones. The first portable cellular phone was unveiled by Motorola in 1983. The cellular phone was called Motorola Dynastic 8000X. The model was approved by FCC in the US. Motorola developed cellular phone technology for years and this model to over 15 years to enter the market costing over $100M. The
