The short range technologies that are used in the mobile phones are the Bluetooth and WiFi connections in them. These help the people to transfer t he files in short ranges, that they have specified limit in them. They could transfer the data from two devices that are nearby this is the easy way to transmit files when compared through internet. This is the fastest way to transfer the data between them. But these short range technologies are not well suited for all types of data. They could use the internet rather than this when they have the file size bigger to transmit. Today the mobile manufacturer produces the device that are designed to this technology, first they introduced the Bluetooth in them and this had a good response from the people and they tried to implement WiFi in them. This short range technology is the one inspired them to have the mobile internet. Today many people like to have the mobile that helps them in faster transmits of data from one another and very high speed.  This shot range technologies help the in the ecommerce of the people they are used for transfer of funds to the account and help them to reserve tickets and they could give the user coupon for the retail store.

General packet radio service [GPRS] is a packet oriented mobile data service on the 2G and 3G cellular communication system’s global system for mobile communications. GPRS was originally standardized by European Telecommunications Standards Institute in response to the earlier CDPD and i-mode packet-switched cellular technologies. It is now maintained by the 3rd Generation Partnership Project. GPRS usage charging is based on volume of data on a pay-as-you-use basis. GPRS is a best-effort service, implying variable throughput and latency that depend on the number of other users sharing the service concurrently, as opposed to circuit switching, where a certain quality of service is guaranteed during the connection. In 2G systems, GPRS provides data rates of 56-114 Kbit/second. 2G cellular technology combined with GPRS is sometimes described as 2.5G, that is, a technology between the second and third generations of mobile telephone. It provides moderate-speed data transfer by using unused time division multiple access channels in. GPRS supports the Internet protocol (IP), Point-to-point protocol (PPP) and X.25 connections. When TCP/IP is used in each phone can have one or more IP addresses allocated. GPRS will store and forward the IP packets to the phone even during handover. The TCP handles any packet loss.

A subscriber identity module or subscriber identification module (SIM) in an integrated circuit that securely stores the service-subscriber key used to identify a subscriber on mobile telephony devices like mobile phones, Wireless Broadband Modems and computers. A SIM is held on a removable SIM card, which can be transferred between different mobile devices. A SIM card contains its unique serial number, internationally unique number of the mobile user, security authentication and ciphering information, temporary information related to the local network, a list of the services as the user has access to and two passwords, PIN for usual use and PUK for unlocking. The first SIM card was made in 1991 byMunichsmart card maker Giesecke & Devrient, who sold the first 300 SIM cards to Finnish wireless network operator Radiolinja. SIM cards store network-specific information used to authenticate and identify subscribers on the network. The most important of these are the ICCID, IMSI, Authentication Key, Local Area Identity and Operator-Specific Emergency Number. The SIM also stores other carrier-specific data such as the Short Message Service Centre number, Service Provider Name, Service Dialing Numbers, Advice-Of-Charge parameters and Value Added Service applications. SIM cards are identified on their individual operator networks by a unique IMSI. Mobile operators connect mobile phone calls and communicate with their market SIM cards using their IMSI’s.

Smarphone which provides advanced features such as music, video, or Internet connection. Characteristic features include an advanced smart phone operating system and application interfaces that allow the installation or modification programs, such operating systems include: Symbian OS, Windows Mobile, IOS, Android, PalmOS. The technology today provides the usual smart phone is as follows: Internet Browser, mobile version of Office system, email client, files manager, Multimedia Player, customization (personalization), memory card support. It is very important to synchronize with a computer, often via the Internet – especially if Android platform. Recently, smart phones had come to the attention of many ordinary users, mainly due to a significant reduction in their prices and the large deployment of manufacturers and distributors as also increases the technical literacy of users. Price range established models ranges 5 to 12 thousand, but due to the large deployment of operators can purchase so-called most models endowed with a minimum flat-rate tariff. With some phones, the manufacturer’s own mobile operating systems, ecosystems have developed to market the developed application software for each platform (Apps). These apps are available via a respective central distribution platform and can be downloaded from there as free or paid. Smartphone has greater marketability among.

A mobile phone company is – as mobile operators or the public mobile telecommunications services to residential and business customers offering. For this purpose applied for or acquired Phone Company in government agencies, a broadcasting license. The process of becoming a mobile operator in a country usually begins by acquiring a license to use the spectrum to the government. The part of the spectrum allocated will depend on availability and type of mobile phone technology as the operator tries to provide. For example, a mobile GSM require a frequency for GSM. The Government can distribute the spectrum using any method, although the most common are contests or auctions. Then build an infrastructure on the licensee namely GSM network or a UMTS network, which covers a specific geographical area of the corresponding license. They provided services for mobile users like pre-paid and post-paid. Unlike the other mobile operators, mobile operators have on the resale of specialized mobile services Mobile Virtual Network Enabler (MVNE) and Mobile Virtual Network Operators (MVNOs). Most of the network uses satellite channel to bring global customers together and they are enhancing with different network partner to reduce the cost of calling charges. After implementation of 3g technology, people are enjoying the differential rates by different network operators.

3G is short or third generation mobile phones. Services associated with the generation of an ability to transmit both – voice or telephone calls and data like download and e-mail messages. The introduction of third generation phones such as flagship applications or video calling was delayed expectations of huge profits from this technology leading to the listing of auctions to sell licenses for this generation. Many countries have shown greater interest in regarding the usage and license of 3G technology to develop IT infrastructure. Even though the license is costly, 3G has multiple values for advancement of IT. Almost every country has 3G technology nowadays for advancement of IT resources. Third generation mobile networks are not networks, according to the standard IEEE 802.11 , but there are networks designed for personal devices such as PDAs and mobile phones . ITU users with data rates of 3G equipment, and providers can expect a clear definition of terms. For this reason, a user of 3G service does not provide standard speeds is not possible to talk about. ITU the minimum or average speeds or qualify as 3G, which did not specify the interfaces, this causes the different speeds of broadband are sold as 3G intended to meet the expectations of speed.
