Today’s mobile phones provide a lot more convenience than being able to take you number with you wherever you go – they have transformed into smart phones and transformed the way we keep in touch. 4G Phones are the state of art, offering reliable voice calling, always-on data, as well as simultaneous voice and data capabilities. Combining these features with the latest operating systems, screens, and keyboards makes 4G phones part of many people’s lives.
4G is short for 4th generation wireless standards. An organization called the ITU is a United Nations agency that focuses on information and communication technology issues. The ITU amalgamates 192 member states, or countries, and is primarily responsible for issuing standards for technologies like 4G. Standards are the technical details about how a phone network and phones interoperate, making it possible for your 4G phone to work with other carriers and assures you of a base set of features on your cell phone, in terms of its communications capabilities.
4G is all about data speed – 4G networks are capable of delivering true broadband speed on the go, making live TV, streaming videos and smooth video calls possible just about wherever you are. 4G standards have changed and there are several approaches carriers like Sprint and Verizon use. Spring uses a technology called WiMax while Verizon uses a technology called LTE. While both carriers implement the 4G standard, the underlying technologies are not compatible, which means that your Sprint phone won’t work in Verizon’s network. Popular 4G phones are available from a number of manufacturers including Samsung, Apple, Motorola, and others. It took a while to get to 4G, and 3G paved the way.
3G represents the third generation of wireless standards and is not compatible with 4G. 3G phones introduced functionality like Mobile TV, Video On Demand, teleconferencing, and location-based services. As a result, 3G phones usually are equipped with a GPS receiver, camera, and are capable of displaying high-resolution graphics. Like the 4G standard, 3G standards also use a number of differing technologies, yet they all focus on one thing – speed. 3G offers better security than it’s predecessor, 2G, by encrypting all voice and data communications boosting your privacy. 2G also offered some great functionality.
The second generation of standards, 2G, merged digitally-based communications with traditionally analog radio networks. Digitally-based communications make better use of resources, provide better sound clarity and call quality, and offer better privacy through encryption. 2G phones were much smaller than their predecessors and 2G phones use far less power than previous phones, boosting battery life and improving communications with carriers’ networks. As with the other standards, 2G is implemented using a variety of incompatible technologies and 2G is not compatible with 3G or 4G networks.
The road to 4G spans about 10 year and delivers on a number of long-standing promises, exceeding people’s appetite for high-speed, mobile, and reliable voice and data communications.
