3. INTRODUCTION
4G(LTE) is the short term for fourth-generation wireless. It is a stage of broadband mobile communications that will supersede the third generation (3G). It is expected that end-to-end IP and high-quality streaming video will be among 4G's distinguishing features.
A 4G(LTE) system will be able to provide a comprehensive IP solution where voice , data and streamed multimedia can be given to the users on “ Anytime Anywhere ” basis and higher data rates than the previous generations.
It will be a fully IP based integrated system capable of providing between 100 Mbps to 1 Gbps in both indoor and outdoor with premium quality and high security.
It was commercially launched in the year 2012.

4. OBJECTIVE
4G-LTE is being developed to accommodate the Quality of Service (QOS) and rate requirements set by forth coming applications like
1. MMS (Multimedia Messaging Service).
2. Wireless Broadband Service.
3. Video Chat.
4. Mobile TV.
5. Digital Video Broadcasting.
6. High Network Capacity.
7. Data Rate of 100 Mbps for mobile and 1 Gbps while stationary .
8. Smooth handoff across heterogeneous network..
9. Seamless Connectivity and Global Roaming across multiple networks.

5. Time-line from 1G to 4G and beyond:
The first generation, 1G wireless mobile communication systems, was introduced in the early 1970s. 1G wireless was analog and supported the first generation of analog cell phones with the speeds up to 2.4kbps.
The second generation, 2G system, fielded in the late 1980s.It was planned mainly for voice transmission with digital signal and the speeds up to 64kbps.
The third generation, 3G wireless system, also called UMTS (Universal Mobile Telecommunications Standard). , was developed in the late 1990s .3G is not only provided the transmission speeds from 125kbps to 2Mbps, but also included many services, such as global roaming, superior voice and video quality.
The fourth generation, 4G is a conceptual framework just raised in The speeds of 4G can theoretically be promised up to 1Gbps. The beyond will be 5G with incredible transmission speed with no limitation for access and zone size.

ABOUT VOLTE DEVICES:
The graph shows an estimate of the total global SHIPPED devices with VoLTE chipset inside (all are not used with live VoLTE services yet).
VoLTE devices launched today are all profiled for a certain operator
All launched devices already exist as non-VoLTE LTE smartphones (CSFB)
Note that the high-end market of LTE Smartphones is predominately being based on Qualcomm Snapdragon 800 family of chipsets (Qualcomm having more than 90% of LTE smartphone chipset market)
Current OEM high-end models, eg Samsung Galaxy S4, S5, Note3, LG G3, Sony Xperia Z2 etc are based on Snapdragon 800.
Note that Snapdragon 800 is VoLTE capable and allows for FOTA upgrade

Ways for standardized voice transfer over LTE
Circuit Switched Fallback
VoLTE packet header size is less compared to a TCP/IP packet hence more band width.

21. What is Wimax ?
WiMAX is a wireless digital communications system, also known as IEEE , that is intended for wireless "metropolitan area networks". WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and miles ( km) for mobile stations. In contrast, the WiFi/ wireless local area network standard is limited in most cases to only feet ( m).

22. WiMAX vs. LTE
The more recent Long Term Evolution (LTE) standard is a similar term describing a parallel technology to WiMAX that is being developed by vendors and carriers as a counterpoint to WiMAX.
WiMAX has more footprint than LTE.

Global Standard:-4G will be a global standard that provides global mobility and service portability so that service provider will no longer be limited by single- system.
Low Cost:– Access technologies, services and applications can unlimitedly be run through wireless backbone over wire-line backbone using IP address.
APPLICATIONS 29

30. FUTURE OF 4G:5G (completed WWWW: World Wide Wireless Web):
The idea of WWWW, World Wide Wireless Web, is started from 4G technologies. The following evolution will based on 4G and completed its idea to form a Real wireless world.
Thus, 5G should make an important difference and add more services and benefit to the world over 4G. 5G should be a more intelligent technology that interconnects the entire world without limits.

31. CONCLUSION
As the history of mobile communications shows, attempts have been made to reduce a number of technologies to a single global standard.
4G seems to be a very promising generation of wireless communication that will change the people’s life in the wireless world.
5G is expected to be launched by 2020 and the world is looking forward for the most intelligent technology that would connect the entire globe.
