4G Definition
4G is not one defined technology or standard, but rather a collection of technologies at creating fully packet-switched networks optimized for data.
4G Networks are projected to provide speed of 100Mbps while moving and 1Gbps while stationary.
1G Technology
1G refers to the first-generation of wireless telephone technology was developed in 1970’s.
Analog signals is used
2G Technology
Around 1980’s
Better quality & capacity - More people could use there phones at the same time
Digital Signals – consist of 0’s & 1’s
3G Technology
Large capacity and broadband capabilities
Allows the transmission of 384kbps for mobile systems and up to 2Mbps
Reasons for New Research
Even though 3G has successfully been introduced to mobile users, there are some issues that are debated by 3G providers and users. High input fees for the 3G service licenses
Great differences in the licensing terms
3G phones are expensive
What is 4G?
Fourth Generation Technology Faster and more reliable 100 Mb/s Lower cost than previous generations Multi-standard wireless system Bluetooth, Wired, Wireless Ad Hoc Networking IPv6 Coreo Primary technologies that support 4G
Eg::WiMax,LTE,UMB
Ad Hoc Networks
Spontaneous self organization of networks of devices
4G will create hybrid wireless networks using Ad Hoc networks
Form of mesh networking–Very reliable
Enhance Mobile Gaming
Experience enhance wireless capabilities that deliver mobile gaming interaction with less than five seconds
Play online multi player games while traveling at high speeds or sitting outside
Broadband access in Remote location
4G will provide a wireless alternative for broadband access
It will provide first opportunity for broadband access in remote locations without an infrastructure to support cable
CONCLUSION:
4G is not a final solution in mobile communication…..The research is going on…
Now a days 5G (5th generation mobile networks or 5th generation wireless systems) is a name used in some research papers and projects
We can expect ‘NEW’ within some months
