Digital phone technology

New technology is constantly being created.Digital phone technology is among that group coming out with several different versions to compete with one another.In fact there is so much digital technology out there today that it can be confusing on which to choose and what provider to go with.The most important consideration for consumers today is to ensure that your phone and service provider are speaking the same language.Let's take a closer look at digital phone technology from the beginning.

Cell Phones
Cell phones are quite simply highly sophisticated radios although we may refer to them as technology.There are cell phone company's located across the country that send their signals through cell towers which we refer to as a cellular network.We as consumers can use those network to receive a signal pretty much anywhere in the country and also in the world.Cellular technology has certainly come a long way.

Analog and Digital
It use to be that in order to get a signal anywhere you had to tap into an analog radio signal.Until digital sound waves made their way into the twentieth century.Analog cell phones used up a tone of bandwidth space and as more and more people began getting and using cell phones the airwaves became very crowded.Digital technology has allowed the phone system to compress more data which allows about ten phone calls to take place in the same bandwidth that a single analog phone call uses.This is also why televisions are moving to digital cable as well; it offers more stations in the bandwidth allotted.Digital phone technology uses the bandwidth much more effectively than analog which is why most cell phones today are digital.

Different digital phone technology
Whenever new technology is introduced there is always competition for the best.Here are a few different technologies when it comes to digital phones:

• TDMA (Time Division Multiple Access).TDMA is a time sharing technology that allows three different calls to use the same frequency at the same time.Since TDMA can handle multiple calls, the digital networks have a call capacity of around 1000, whereas analog only has about 100.


• CDMA (Code Division Multiple Access).CDMA does just what its names says; send a unique code to each call within the system.This allows different calls to switch from frequency to frequency at any given moment without getting lost and with little interference.CDMA uses whichever bandwidth that is available which enables CDMA based digital networks to have about ten thousand more calls than analog does.


• GSM (Global Standard for Mobile Communications).GSM borrows from CDMA and TDMA digital networks.It encodes the calls and also separates them into multiple time slots.GSM was developed in Europe which is where they operate, although there is a North American GSM that operates on a different frequency.So if you're using a North American GSM phone it won't work if you are in Europe because it carries a different frequency.

Digital phone technology has definitely made its turning point and is becoming the most popular way to communicate; not only over the phone but also with television going digital.It's faster, easier, and sooner or later everyone will have to go digital if they want to keep up with the changing times.
