People like to stay in touch and because of technology we have many ways to communicate with one another. Because of the inventions of the telephone, cellular phone, and also the Internet like e-mail and instant messenger we can talk any time. What is popular today is that people can communicate anywhere. The invention of the pager and cellular phone now allow people to talk anywhere.
Pagers and cellular phones have been growing and more people have them over the last 15 years. Which one is going to stay popular and help people keep communicating with each other? The pager or beeper is a dedicated RF (radio frequency) device that allows the pager user to receive messages broadcast on a specific frequency over a special network of radio base stations. A person with a pager can either get pages from a telephone number, text messaging on the screen or the person dials up there number and puts there code in and gets a voice message from the person that is trying to contact them. The Detroit Police Department in 1921 used the first pager like system. The term "pager" was first used in 1959, referring to a Motorola radio communications product, a small receiver that delivered a radio message individually to those carrying the device.
The first pager, as we are familiar with them today, was Motorola's Pageboy I, introduced in 1974 (web 1). The pager at that time had no displays like todays pagers and could not store messages, but it was portable and could notify the person that a page had been sent. How pagers or beepers work? Pagers are a portable communication messenger device. The person sending the message uses a touch-tone phone and calls the pagers' number, then the person enter their number or voice message and within moments the pager carrier is notified by an audible "beep" or a silent vibration.
The number or voice message can be read on the pagers's creek. By the 1980 s pagers grew and more people wanted to be able to communicate with each other. In 1980, there were about 3. 2 million pager users in the world. But at this time there was a limited range people could use the pagers. Also they were used for only on-site situations like for medical workers within a hospital (web 2).
Hospital workers have them in case of emergencies and the doctor needs to get to a very ill person. 1990 invented wide area paging and over 22 million pagers were in use at that time. But only 4 years later over 61 million pagers were in use and that is when pagers became popular for personal uses not just business use. There are different kinds of pagers people can buy and use. The one pager is the numeric pager it just prints the numbers of the person who called. How a person does this is the caller dials an access number, enters a PIN of the person he or she wants to reach, and then enters their phone number and hits the # button.
A person with this pager can get service for parts of countries. Another pager is the alphanumeric pager, which prints a text message up to 80 characters. What the person does to get a hold of the person they are trying to contact is the caller delivers a message to a human operator, which types the text message to the pager. Having this pager you have more range of getting pages, you could be in New York City, Grand Rapids, on the ground or at 35, 000 feet.
With either service, you get the messages within a minute or two after they are sent (Sullivan 128). Further, there is the digital pager, which transmit the number to call or a brief message by appending digital codes to the paging signal (Straubhaar, LaRose 329). With these pagers you can get stock market quotes and sports scores. Another pager you can buy now a day is the two-way pager. A person can type a message to a person like What time are you coming home for dinner? and the other person now can answer 6: 00 or 7: 00 because of two-way paging.
Pagers in the early 1990 s were the craze and everyone from lawyers to teenagers had one at that time. But pagers at this time started to become no longer cool and people started to buy cell phones because it became the norm with the both professionals and teenagers which once had pagers. Now you dont hear the beeping and buzzing of a pager but the ringing and different musical sounds from a cellular telephone. Why there was a decline in pagers was because in the recent years the price of cell phones have dropped and they have great deals with these phones. The concept of the cellular phone began in 1947 when some researches took a mobile car phone and realized that by using small cells range of service area that you can still communicate. In 1973, Dr.
Martin Cooper patent the cellular phone for Motorola. Cellular is a type of wireless communication that is most familiar to mobile phones users. Cooper made the first call on a portable cell phone in April 1973 (web 1). However, Motorola was the first to incorporate the technology into portable device that was designed for outside of a automobile use. It's called cellular because the system uses many base stations to divide a service area into multiple cells. Cellular calls are transferred from base station to base station as a user travels from cell to cell.
When having the first cell phones they operated from a single antenna and could only handle 46 simultaneous conversations in one area. This meant that when the 47 th caller dialed up they would receive a dial tone (Straubhaar, LaRose 329). But people using cell phones were growing and they could only use a limited number of channels. Changes and the growth of cellular telephone expanded customers and service of cell phones. In 1978, Advanced Mobile Phone Service or AMPS started to operate in North America which was a cellular telephone service. They had ten cells covering 21, 000 square miles in the Chicago area which was a trial run but after 6 months the marketed the phones into cars.
The new cellular phone system had over 2000 trial cellular phone customers (web 3). In 1982 the FCC finally authorized commercial cellular phone service in the USA. A year later the first American commercial cellular phone service AMPS was offered an analog phone service bye Ameritech. Even with such a demand for cell phones in the United States it took cellular phone service 37 years to become commercially available.
Consumer demand quickly outstripped the 1982 system standards. By 1987, cellular telephone subscribers exceeded one million and the airways were crowded. The three ways the FCC could improve the service was one increase frequencies allocation, two split existing cells of three improve the technology. The FCC did not want to handout any more bandwidth, and building / splitting cells would have been expensive and would have added bulk to the network. To stimulate the growth of new technology, the FCC declared in 1987 that cellular licensees could employ alternative cellular technologies in the 800 MHz band. The cellular industry began to research new transmission technology as an alternative.
