When cellular phones first came out, the only thing that they could do was make calls. Later, features such as text messaging came out. Eventually, \a new technology came out that allowed cellular phones better data access, enabling them to check email, access the Internet, even instant message others over a cellular network. This technology is known as GPRS, and it's one of the primary technologies used for mobile internet access in the United States and abroad.
Background
GPRS stands for General packet radio service. The system consists of sending and receiving of several bits of information, known as packets, from the cell phone to the network. Unlike older models and internet technologies such as Dial-up, GPRS separates the individual packets and splits them up along different lines of a cell phone network, thus increasing speed of the network.
What GPRS offers
GPRS technology offers several features that bolster the cell phones in its network. For one, the network connection is "Always on," meaning that there is no disconnection problems like there are with dial-up and older phone companies. Another feature GPRS offers is being able to allow Internet access to cellular phones as well, and offer it at a fast rate.
Usage
GPRS can be used for several purposes. The primary use is to help make sure the phone is connected to the cell phone network. More user-friendly options include the ability to surf the web and check email. Phones with GPRS capabilities typically come with software, such as an email client and web browser, that are capable of using GPRS to surf the Internet.
Disadvantages
Although GPRS offers a good connection to the Internet, it still isn't very fast. The maximum speed of a GPRS connection is still slower then a 56K model speed--Around 35 kilobits per second. In addition, the cost for 1 megabyte of data can be quite extraordinary, and if you're not careful, you could receive an extremely thick bill in your mailbox, with an equally think total amount due.
Future technology
GPRS unfortunately is on the way out. Newer, more faster technologies such as HDSPA and WiMAX are taking control of the mobile market, and cell phone providers are leaving GPRS behind in favor of the faster technologies. In the case of WiMAX, a network can be made much cheaper and faster then a network that uses GPRS, and could potentially cost less as well.
