The fourth generation of wireless in the field of mobile communications (broadband) is called 4G. This fourth generation technology is used across segments. Many organizations in the government sector, public sector units and corporate sector have absorbed the usage.

This technology has many additional facilities when compared with the 3G or 2G. This is a more advanced model. The label 4G specifies that the customer can expect higher data transfer speed. The signal is split to multifarious channels possessing different frequencies.

The 4G provides Identity Management Solutions in the market of India. The system is absolutely secure. The identification as well as verification applications are highly developed. The 4G though new in the Indian Scenario has created a niche for itself in various sector of the Indian market. The identity management is facilitated by the demographic search engines, biometric algorithms and multiple biometric devices.

OFDM (the indicator of 4G): OFDM (orthogonal frequency-division multiplexing) are used by the carriers for successfully installing 4G spectrum. The carriers univocally accept that usage of OFDM entitles the service to be marketed as being 4G.

The 4G wireless levels: This has the foundation on a total IP packet network. The data transfer is almost 100 megabits per second for mobile usage. The stationary usage options offer data transfer of 1 gigabit per second. It uses the shared network system. The changeable bandwidth varies between 5 and 20 megahertz, but may go upto 40 megahertz. The change over heterogeneous networks is smooth. The technology supports the usage of the multimedia to a great extent.

Unlike the 3G this generation of mobile communication (4G) needs at least carrier of capacity 2×5 Mega Hertz. This facilitates the mobile (GSM) operators to switch over easily from one link to another.

History of the 4G Spectrum:

The naming of the technology is based on the generation. There are fundamental changes in the types of services, transmission feasibility and frequency bands. The 1G appeared in the market in 1981. Subsequently the 2G made its way in 1991. After another ten years the 3 G made its foray into the utility. The year 2011 launched the 4G, though few government projects had successfully accomplished their jobs using the 4G spectrum in the earlier period.

The LTE (communication standard) and the WiMAX (Worldwide Interoperability for Microwave Access) usages are taken to be pre-4G technology. They do not comply with the requirements totally. Few products launched as 4G actually used 3.9G. They do not comply with the 4G attributes.

The recent news in the market (Indian telecom) is that the TRAI (Telecom Regulatory Authority of India) invited views and comments of different stakeholders for developing a consultation paper. This is the primary step for introducing the 4G services in the country. The main aim of this exercise is to highlight the idea to the government to facilitate higher allocation of funds. The TRAI is trying to imitate the markets in US, Europe and East Asia where the initiation of the 4G Technology has progressed ahead.

Basic Requirements to set-up 4G network:

The basic requirement to set up a 4G network is a mobile device (for data exchange at the rate of 100 megabits per second). If successfully installed the 4G is expected to facilitate seamless communications covering a vast geographical area. Public and personal usage of this technology by mobile users will be more effective when "picocell" and "femtocell" are used.

AADHAAR (Unique ID) Project:

The identification of Citizen ID by the government is truly benefited by the 4G spectrum. End-to-end solution is available for enrollment (biometric) and duplication of databases. The details of the face, finger and iris is vital for this identification system supported by 4G. The project accomplished by the UIDAI (Unique Identification Authority of India) provides a unique identification process for the residents of the country. The identification is universal and accepted without haste all over the country. A number is allotted to the individuals. The 4G spectrum makes it a cost-effective process. It provides biometric solutions (BSP). The Aadhaar Enrolment Application integrates the quality checks (biometric). The 4G helped the project to deploy the proof of concept for the first time.

Coastal ID- National Population Register:

The hardware (biometric) and the solution integration components integrate the fourth generation spectrum. The project on National Register (Costal ID) of the consortium of companies in the public sector like ITI, BEL and ECIL use this technology. Roughly 12 million people live in the shorelines of India and approximately 4 million in the Union Territories. All these people have been covered in the first phase of the project.

Largest De-duplication (Biometric) Project in the World:

The 4G facilitates the largest De-duplication project in the world. The project is initiated and invigilated by the Government of Andhra Pradesh. Approximately, 30 million survey sheets have been collected for verifying the details of the households in the states which have been covered. 6.26 quadrillion Iris have been matched to remove duplicate cards. The demographic match software had been used to filter the duplicate enrollments.

Only the genuine ration cards are accepted after this project in many states. This saves a huge expense which was being shouldered by the government by bogus ration card holders.

Biggest ID project (Multi-biometric) for PDS:

The targeted public distribution system (PDS) is enabled to offer an end-to-end life cycle solution by the 4G spectrum technology. The process comprises of ration cards issuing, biometric enrollment, biometric de-duplication, data digitization and point of vending facilities in the Fair Price Shops.

Recent News of 4G

Mobile broadband provider "Infotel" purchased the biggest share in the 4G spectrum. They won the bid for as many as 22 regions. The company has broadband (wireless) communications all over the country. This makes the company the top-rung ruler in the world of mobile technology in India. Now, it is incorporating the 4G technology. Let us see what the future of this country holds for the affinity towards the 4G technology.
