What is 4G? Definition and Uses

When cellular technology first began, there was no standard definition for high speed Internet. Years later, the Federal Communication Commission (FCC) defined the standard definition for what is the fastest internet connection available. The current definition is called GSM, which stands for Global System for Mobile Communications. There are four different types of GSM networks. The CDMA, which provide only voice communications; the TDMA, which provide data communication; the EMT, which provide both voice and data; and the IMTS, which are used in Europe.

4G refers to a new type of cell phone service that offers support for features that would otherwise be found only on mobile phones. 4G has the same characteristics as CDMA and TDMA, but provides support for a wide variety of data services. In general, this means that you will be able to access internet applications that do not exist on a regular telephone.

A major advantage to choosing a fourth generation technology like GSM is the availability of high speed internet access. Today, more people are able to take advantage of online applications, like video conferencing or remote access, that they might not have been able to before. With the introduction of GSM devices, a person can take advantage of voice calling and video conferencing over a wide area network, instead of being limited to a particular carrier. This is especially helpful for business owners who want to expand their business globally, but who do not wish to tie up their phone line with a specific carrier.

Another advantage to choosing a fourth generation phone system like GSM is the ability to send and receive text messages at unbelievable speeds. Typical cell phone services may send text messages at around 30 frames per second, which may seem slow. However, when a person uses a high-speed connection like GSM, they can experience messages that come in at the speed of light. This is especially useful for those who want to get their hands on important business information that cannot be immediate sent through normal channels.

Many of the new features available in the new generations of cell phones, like the introduction of HSDPA (High Speed Digital Access), can also be found in a GSM device. HDPA stands for High Speed Data Protection and is basically a security feature that helps to protect the personal information on a GSM device from data thieves. For instance, if someone were to break into your office and take information from the computers, they would not be able to use your computer’s file system to upload the stolen information onto their own personal device. By using HDPA, the phone will let the user know exactly who made the transmission, so that there won’t be any mistake. Because so many businesses are using video conferencing, this new security feature is vital to everyone.

The last thing to discuss in this article is the availability of a high-speed internet access in a mobile or a smart phone, whether it is capable of supporting a GSM connection or an IP connection. Some mobile devices have been released that already have both, such as the Blackberry Q10 and the HTC StrTrk. These phones are only capable of supporting one type of technology, but there are other newer models that are equipped with both GSM and IP networks. To find out more about the availability of a high-speed internet access in a smart phone or if a particular mobile phone has both GSM and IP capabilities, check the online features database for your specific phone model.
