Mobile and wireless networks have made significant improvement in the last few years. At the current time many mobile phones have also a WLAN adapter. One may expect that near soon many mobile phones will have Wax adapter too, besides their 3G, 2G, WLAN, Bluetooth etc. adapters. We are using IP for generations, 2.5G or 3G Public Land Mobile Networks (PLMN) on one side and WLAN on the other, developed study on their incorporation. With reference to the 4G, its focal point is towards flawless integration of cellular networks such as GSM and 3G. The multiple consumers put plants as it should be for 4G, but private security mechanisms and private support for the operating system in the wireless test techniques remain. However, the application of a combination of different wireless networks (such as PLMN and WLAN) is in practice until the present time. Although, different wireless networks from only terminal are used absolutely, there is no combining of dissimilar wireless access technologies for an equal session (e.g., FTP download). The predictable Open Wireless Architecture (OWA) in is targeted to offer open baseband processing modules with open interface parameters. The OWA is related to MAC/PHY layers of future (4G) mobiles . New error-control schemes can be downloaded from the Internet and augmentation is seen towards the customer terminals as a focus on the 5G mobile networks. The 5G terminals will have software defined radios and modulation scheme and the 5G mobile terminals will have access to diverse wireless technologies at the same time. And also 5G mobile terminal should be proficient to merge special flows from different technologies. The 5G terminal will make the final selection among diverse mobile access network providers for a particular service. The network will be reliable for managing user-mobility. The paper gives the concept of intelligent Internet  phone where the mobile can prefer the finest connections .
2. Challenges in Migration from 4G to 5G
Presently, 5G is not a term officially used for any particular specifications.3GPP standard release beyond 4G and LTE . 5G Technology is a name used in a range of research papers and projects to point to the next most significant stage of mobile communication values beyond the 4G standards. The execution of standards under a 5G umbrella would likely be around the year of 2020. The following are the main constraints for migrating from 4G to 5G.
A. Multi mode user terminals
This trouble caused by means of 4G can be solved by using software radio approach. There will be an essential to design a single user terminal that can operate in different wireless networks and overcome the design troubles such as boundaries on the size of the device, its cost and power utilization.
B. Choice among various wireless systems
Every wireless system has its distinctive characteristics and roles. The choice of most suitable technology for a specific service at a specific place and at precise time will be applied by making the choice according to the best possible fit of consumer QoS (Quality of Service) requirements.
Mechanisms with adaptive, reconfigurable, and lightweight protection should be designed.
D. Network infrastructure and QoS support
Integrating the current non-IP and IP-based systems and providing QoS assurance for end-to-end services that engage different systems is a challenge.
E. Charging and Billing
It is hard to accumulate, handle and accumulate the Consumers’ account information from many service providers. Consumers’ billing is also a difficult task. Attacks on Application Level Software applications will offer new feature to the consumer, but will commence new bugs.
F. Jamming and spoofing
Criminals can make use of such techniques. Jamming occurs when a transmitter sending out signals at the same frequency shifts a GPS signal. Spoofing is fake GPS signals being sent out, in which case the GPS receiver considers that the signals arrives from a satellite and computes the wrong coordinates Data Encryption. If a GPS receiver will communicate with the main transmitter then the communication link between these two is not tough to break and consumer must use encrypted data .
3. Key Terms of 5G Technology
While considering a smooth migration for 5G it is apparent that it should be valid for all sorts of radio access technologies. So that it could make better revenue for current global operators as well as interoperability will become more feasible. To make 5G practical for all sorts of radio access technologies there should be some key terms of 5G technology as follows:
1. People called it REAL wireless world 5G is a completed wireless communication with almost no limitation; somehow Additional features such as Multi- media Newspapers, also to watch T.V programs with the clarity as to that of an HD T.V.
2. We can send Data much faster than that of the prior generations and 5G will bring almost perfect real world wireless or called “WWWW: World Wide Wireless Web
3. Real wireless world with no more limitation to access and zone issues and wearable devices with AI capabilities.
4. Internet protocol version 6 (IPv6), where a visiting care-of mobile IP address is assigned according to location and the connected network .
5. One unified global standard and persistent networks providing ubiquitous computing: The user can simultaneously be connected to several wireless access technologies and seamlessly move between them. These access technologies can be a 2.5G, 3G, 4G or 5G mobile networks, Wi-Fi, PAN or any other future access technology . In 5G, the concept may be further developed into multiple concurrent data transfer paths .
6. Cognitive radio technology, also known as smart-radio: This dynamic radio resource management is achieved in a distributed fashion, and relies on software defined radio allowing different radio technologies to share the same spectrum efficiently by adaptively finding unused spectrum and adapting the transmission scheme to the necessities of the technologies currently sharing the spectrum. See also the IEEE 802.22 standard for Wireless Regional Area Networks .
7. High altitude stratospheric platform station (HAPS) systems.
4. 5G Technology Requirements
As a result of this blending of requirements, many of the industry initiatives that have progressed with work on 5G identify a set of eight requirements:
1. 1-10 Gbps connections to end points in the field (i.e. not theoretical maximum)
2. 1 millisecond end-to-end round trip delay (latency)
3. 1000× bandwidth per unit area
4. 10-100× number of connected devices
5. (Perception of) 99.999% availability
6. (Perception of) 100% coverage
7. 90% reduction in network energy usage
8. Up to ten year battery life for low power, machine-type devices
Because these requirements are specified from different perspectives, they do not make an entirely coherent list―it is difficult to conceive of a new technology that could meet all of these conditions simultaneously.
