As the need for communication rather fastest communication is the foremost priority of present era also the need of quick data transfer. Distant business correspondence by sharing data becomes very important. Ever growing technology is the example of one such step towards the fastest transmission of data. 4G stands for Fourth Generation is the latest technology with high speed transferability of data with security measurements. It is coming with wireless broadband for the instant download.
Talking about the standard of 4G technology, still not defined as set standard, two technologies are supposed to be the based features of 4G.
ITU promotes the technologies against the defragmentation and incompatibilities in 4G technologies.
WiMAX stands for Worldwide Interoperability of Microwave Access previously worked as fixed wireless facility under the 802.16e band. Now the modified standard 802.16m has been developed with the properties of speed, wide spectrum, and increase band.
4G has an advantage of having the WiMAX as a product because IEEE introduces and releases it already therefore economic as no need to pay for its manufacturing price. 4G supports two basic equipment’s;
- WiMAX Network system (network infrastructure)
- mobile phone set
Smartphones with Wireless Access are going to be introduced in the market are the model 4G mobiles. These smartphone are equipped with the wireless internet accessibility and no fear of losing connection while travel from one tower to another tower range.
Based on the IP wireless connectivity, it increases the optimization for the internet. It manages the voice through packet-switching instead of circuit switching. Internet connectivity with specific IP not only increases the speed but also reliability of the sending and receiving of data.
During a phone call when caller send the information by connecting to WiMAX network, this information first processed to the internet home and then spread widely. Most of the time this transmission happens very fast problems arise in case of spectrum, bandwidth and data. In case spectrum is not wide, shorten bandwidth and specific data carries through the internet. Arrival of 4G has diminished all the fears of lower bandwidth, narrow spectrum and amount of data send / receive. This WiMAX technology has a high speed of data transfer rate with additional capacity for the subscribers and ready to carry big amount of data. Previous generations were suffering because of low speed which ultimately covered in the 4G.
Parallel to WiMAX, LTE (Long Term Evolution) is introduced by Verizon. LTE is considered to be promising high data transfer speed. LTE is supposed to provide internet facility using both systems. It has the ability of transition from one mode to another. LTE is developed on radio waves technology. This not only increases the speed but also the amount of data allowed through the same bandwidth and results into lower cost.
As LTE is compatible with 3G technology so it not only increases the speed but also prevents the need of new network and can work through the same infrastructure. LTE will not only support the functions of 3G but also incorporate some newer ones. LTE is using MIMO (Multiple input multiple output) able to send and receive huge data negative in the sense that it will overload the base stations networks.
While seeing the working methodologies of both technologies considered to be the standards of 4G, the future is of mobile business.
