This is Los Angeles. In 1947, the fundamental idea of cellular phones was first conceived. Motorola was the first company to combine the technology into a portable device that was meant for use outside of a vehicle. Bell Laboratories was the company that originally established the concept of cellular communications in 1947 with the technology that was used in police cars. During the same year, AT&T made a proposal to the Federal Communications Commission (FCC) to allot a significant number of radio-spectrum frequencies. This was done with the intention of making widespread mobile telephone service possible and providing AT&T with an incentive to conduct research on the emerging technology. The Federal Communications Commission (FCC) would be responsible for regulating broadcasting and the transmission of a message via radio or television over the airways. When the Federal Communications Commission (FCC) revised its stance in 1968, it increased the distribution of frequencies, which made the airwaves available for more mobile phones. Bell Labs and AT&T came up with the idea of a cellular system that would consist of a huge number of low-powered, tiny broadcast towers. Each tower would cover a ‘cell’ that was a few miles in radius, and the system would cover a greater region collectively. It was intended that each tower would only make use of a small portion of the overall frequencies that were allotted to the system. It was common practice for calls to be transferred from one tower to another when the phones moved throughout the region. In April of 1973, Dr. Martin Cooper, who had previously served as the general manager of the systems division at Motorola, is credited with making the first call on a portable cell phone. The call was made to Joel Engel, who was the head of research at Bell Labs. Cooper is considered to be the inventor of the first modern portable handset. Between the years 1977 and 1978, AT&T and Bell Labs worked together to build a prototype of a cellular system. In 1978, public trials of the new system were initiated in Chicago, with more than two thousand trial consumers participating. It was in 1979 that a new endeavor, the first commercial cellular telephone system, commenced operations in Tokyo. This was two years after the first project. The seventies were a time when mobile phones showed a lot of promise. Motorola and American Radio Telephone initiated a second test of a cellular radio-telephone system in the United States in the Washington, DC and Baltimore metropolitan region in the year 1981. The slow-moving Federal Communications Commission (FCC) ultimately permitted commercial cellular service for the United States of America in the year 1982. Cellular phone service did not become commercially accessible in the United States until 37 years after it was first introduced, despite the enormous demand for it. Within a short period of time, customer demand rapidly outpaced the system requirements that were in place in 1982. By 1987, the number of cellular telephone users had surpassed one million, and the airways were congested. It was during that year that the Federal Communications Commission (FCC) announced that cellular licensees might use alternative cellular technologies in the 800 MHz band in order to encourage the development of innovative technology. In 1988, a different organization known as the Cellular Technology Industry Association (CTIA) was established with the purpose of collaborating with cellular service operators and researchers in order to determine the requirements for new technology and to establish objectives for the introduction of a new product by the year 1991. Shortly after that, the telecoms industry organization (tia) developed a standard specification that was based on the needs that the ctia had suggested. As a consequence of this, the wireless network partitioned them into time slots, with each phone user having access to one time slot at predetermined intervals. In the next section of this unit, we will talk about various time intervals. As a result of all of these advances occurring in fast succession, a large number of cellular phone manufacturers, telecom companies, entrepreneurs, and innovators started joining this very potential industry. Text messaging was initially introduced by Neil Papworth in 1992, when he sent the first text message, which said “merry christmas” via a personal computer to Richard Jarvis, who worked for Vodaphone. Another one of IBM’s personal communicators, the IBM Simon, was released in the year 1992. Due to the fact that it was the first mobile phone to include several functions from the personal digital assistant (pda) that was popular at the time, the Simon is universally acknowledged as the very first smartphone in the history of the worldwide market. The Simon was a really groundbreaking smartphone that was only produced in a limited quantity of 50,000 units before manufacturing was halted in 1995. It was the device that laid the groundwork for all subsequent cellphones, including downloaded applications. An application developed by a third party for the IBM Simon was announced in a press release that was sent by IBM. The program was scheduled to be made available in the spring of 1995. Both IBM and the application development company with which they had a partnership were unaware of the fact that the great inventor andre gray had released the world’s first ringtone, “toccata and fugue in d minor,” as well as a downloadable application called sync programming language on February 5, 1994. This was more than a year before they made such an announcement. It was the sync programming language, which was the first ringtones and ringbacks programming language in the world, that served as the foundation for the multi-trillion dollar downloadable app industry that exists today. Without this language, there would be no Uber, Snapchat, Instagram, or any other downloadable app that is currently available on all 15 billion cell phones in the world. On the other hand, gray had not yet completed the transformation of the cell phone. Microgrooves electronic was first introduced by Andre Gray in July of 1998 at a digital music conference held in New York City. Gray demonstrated the software on his reliable IBM Simon. Microgrooves-e is a multimedia and entertainment application that can be downloaded into mobile devices. It gives users the ability to play songs, complete albums, and movies. In addition, microgrooves-e enabled the recording and playback of audio and video information. The whole groundwork for the future of smartphones had already been built and established by the time the 1990s came to a close. Dr. Martin Cooper, IBM, and André Gray were at the very core of the foundation, and they were responsible for practically all of the hard lifting. There was a huge feeling of hope and technical optimism in the air as the new year’s eve of 1999 approached, and the 21st century and beyond owe a great deal of their existence to the 21st century. Dr. Martin Cooper and Andre Gray, the two most significant contributions to the development of the mobile phone into what it is today, deserve a tremendous deal of thanks; yet, a simple text message of gratitude will suffice.
