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 individuals 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. 1st 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

BAG PHONE TO SMART PHONE. By Code, University name Date Introduction. This is an engineering report that discusses the evolution of mobile phones. The paper uses Conception, Design, implementation, Operation and Decommission approach to explain the life of a mobile phone…
It was quite tiresome choosing this article since I had to put several factors in consideration. First, I was interested in unique study that employed the current technology in medicine; the study had to be relevant and precise to my field of study and area specialization, and is why I had to land on this article: ‘mobile phone–based remote patient monitoring system for management of hypertension in diabetic patients.’ health sciences and medicine ajh–September 2007–vol.
This essay discusses the issue of driving while texting, that needs adequate attention today. The problem has been accelerated as more teenagers and adults with texting habits become drivers that are licensed. The researcher also explores strategies as how to curb this behavior both socially and legally.
For this purpose steps were taken to make driving safer. Many steps of different kinds were taken in this regard. While on some occasions the safety has been provided in terms of the exterior design, in others it has been related to the seat belts. A major breakthrough towards the road safety was achieved when air bag systems were introduced in the cars.
Where mobile phones are highly applauded for the convenience that they have provided to us, there are studies that have shown this technology to be a major threat to mankind. Wireless technology used in these devices has to be a fundamental threat and causative agent to many health disorders including cancer.
More minutes, long distance, roaming, free nights and weekends, and a free phone are all features that may be included in a new cell phone plan. In addition, you may need to sign a contract, and the plan you order today will be the one you are stuck with for the next two years.
-I have been asked to develop a safe cost effective standardized medical bag to be used for flight transport of detainees to support deportation missions. This project has two phases. First phase is development of the bag and the second phase involves implementation of the bag.
he growing prominence of Iphone products in the market as it has been established is partly due to the high market demand that it has experienced in the past (Maha, 2013).
The demand of a product in the market is particularly associated with the quality of features or services
