... difference between analog and digital cellular? Commercials about a 100 % digital network scream from the TV. Print advertisements' black ink blare the magic of "digital" wireless services. More and more wireless services are touting the benefits of an all digital network. So what exactly is the big deal with digital and how does it compare to analog cellular technology?
Here's a look at where digital and its predecessor cellular technology came from and where's it going so you can decide if your wireless phone should talk digital or not. In the 1990 North America started going digital because they need to increase capacity. In March of 1990 they picked digital cellular which cut down the voice channels from 30 KHz to 10 KHz (web 2). Many nationwide wireless service providers have a digital network in place or are at least in the process of trying to convert their cellular network to a digital network. The reason is digital presents many advantages over cellular. The main benefits of digital include better quality of service, more security for the customer, and the ability to support next-generation services.
Operators are looking to digital technology to help enable the whiz-bang services of tomorrow, like wireless Internet applications. Digital is known to up the efficiency in the network, meaning an operator can fit more information into each transmission; that's why so many are now converting their systems to digital. You can increase capacity by switching over to digital cellular. For a wireless operator, this means that they can get more bang for their buck from their network.
Operators using digital would also be able to supply their customers with the hottest new services that were being talked. Some of these services include features that customers had already gotten accustomed to on their regular phone, like wireless call waiting, as well as some messaging services. Digital offers a better quality of sound. Proponents of digital claimed too that because digital scrambled up the signals into bursts, it was more secure than analog and can help thwart cloning, an act of grabbing phone account information over the air in order to copy then resell that information for piracy purposes.
By some industry estimates, close to $ 650 million in wireless services has been coveted by these big-eared crooks, which only adds onto the operator's bottom line a cost that is eventually passed on to the customer. Digital has stronger battery life than analog, and for the most part, better, more modern features on the phones. Analog technology refers to electronic transmission accomplished by adding signals of varying frequency or amplitude to carrier waves of a given frequency. Analog cellular use more voice channels and is not as clear as digital cellular phones. Roaming may be more difficult using a digital based phone than an analog cellular.
Since today there is no single accepted industry standard in digital technology and the technologies are incompatible, roaming or using another wireless operator's network while traveling may be difficult. By the early 1990 s cellular telephone was finally world wide and the three many areas where cell phones were bought than were Scandinavia, the United States and Japan (web 3). By 1992 two companies created wireless cellular and in March of 1993 Japan went to digital cellular. By the mid- 1990 s America needed more wireless channels and the existing cellular bands had no more room. Finally the United States got more service and many more frequencies were needed to handle all the customers. The FCC got new licensing for wireless use and the FCC began auctioning new designated PCS bands from December of 1994 to January of 1997 (web 4).
The result was that several carriers being licensed in each metropolitan area and the FCC thought that the new competition would bring lower rates. The lower prices did not occur at this time. But cellular prices now have gone down because of the different offers each company offers now. It seems like pagers and cell phones will be fighting it out all the time. In the early 1990 s more people had pagers so they could keep communicating with one another.
But now cellular telephone have taken over. It was only about five years ago that pagers or beepers were the ultimate status symbol. Doctor wore them, techies clipped them onto their belts, drug dealers used them and kids who didn't own pagers gazed with envy at kids who did. But that changed almost overnight. The once popular item is now on its way to extinction, thanks to the proliferation of cellular phones. While the cost of pagers is less than that of mobile phones, the mobile phone service is so inexpensive, so ubiquitous, and you get so much for it that the idea of a separate pager.
The debate is whether pagers or cellular phones networks will offer the best wireless system for a person (Berlin 1). While the company no longer provides results on the paging business, he estimates that sales have dropped since then to $ 700 million in 2000 and an expected $ 430 million in 2001. Sales have been going down for Motorola's pager business for a long period of time now because people are buying cellular phones to communicate with one another. Pagers were once a strong industry that easily beat the mobile phone business in the early 1980 s. Then, mobile phone service, which preceded current cellular service, was more primitive, limited in scale and pricey.
It was a no-brainer for customers to choose pagers that sold for $ 300 to $ 400, compared with mobile phones priced at$ 3, 000 to $ 5, 000. That changed as telecommunications firms developed more reliable cellular networks, attractive cell phones, and dropped service and phone prices. Compared with paging services, which cost about $ 10 a month, consumers could get a basic service with more features than pagers for about $ 20. Wireless firms also heavily subsidized mobile phones so customers could receive one free with service or pay just a little more for a better phone.
Really it is the person choice if they want a pager or a cellular phone now a days. Technology is changing so much anymore that next cellular phones are going to change to something more advanced. If you really want someone giving their number to you or writing messages to you but if you just want to talk you should invest in a cellular telephone. Work Cited Berlin, David.
