what is 5G?

• While 5G isn't expected until 2020, an increasing number of companies are investing now to prepare for the new mobile wireless standard. We explore 5G, how it works and its impact on future wireless systems.
• 5G simply stands for fifth generation and refers to the next and newest mobile wireless standard based on the IEEE 802.11ac standard of broadband technology, although a formal standard for 5G is yet to be setccording to the Next Generation Mobile Network's 5G white paper, 5G connections must be based on 'user experience, system performance, enhanced services, business models and management & operations'.
  And according to the Groupe Speciale Mobile Association (GSMA) to qualify for a 5G a connection should meet most of these eight criteria:
1. 1.One to 10Gbps connections to end points in the field
2. 2.One millisecond end-to-end round trip delay 
3. 3.1000x bandwidth per unit area
4. 4.10 to 100x number of connected devices
5. 5.(Perception of) 99.999 percent availability
6. 6.(Perception of) 100 percent coverage
7. 7.90 percent reduction in network energy usage
8. 8.Up to ten-year battery life for low power, machine-type devices
• Previous generations like 3G were a breakthrough in communications. 3G receives a signal from the nearest phone tower and is used for phone calls, messaging and data.
  4G works the same as 3G but with a faster internet connection and a lower latency (the time between cause and effect).

               

Advantages of 5G

• Like all the previous generations, 5G will be significantly faster than its predecessor 4G. 
  This should allow for higher productivity across all capable devices with a theoretical download speed of 10,000 Mbps.
  "Current 4G mobile standards have the potential to provide 100s of Mbps. 5G offers to take that into multi-gigabits per second, giving rise to the ‘Gigabit Smartphone’ and hopefully a slew of innovative services and applications that truly need the type of connectivity that only 5G can offer," says Paul Gainham, senior director, SP Marketing EMEA at Juniper Networks.
  Plus, with greater bandwidth comes faster download speeds and the ability to run more complex mobile internet apps.
• Disadvantages of 5G
• However, 5G will cost more to implement and while the newest mobile phones will probably have it integrated, other handsets could be deemed out of date.
  A reliable, wireless internet connection can depend on the number of devices connected to one channel. With the addition of 5G to the wireless spectrum, this could put us at risk of overcrowding the frequency range.
  The problems with 4G and even 3G aren't exactly filling us with the hope of an immediate super fast connection.
  For a long time (and still even now) certain handsets and areas of the UK don't support or can access 4G connections, so the rollout for 5G is likely to be very patchy.
  

Key Concepts of 5G

• Suggested in research papers discussing 5G and beyond 4G wireless communications are:
•  Real wireless world with no more limitation with access and zone issues. 
• Internet protocol version 6 (IPv6), where a visiting care-of mobile IP address is assigned according to location and connected network. Wearable devices with AI capabilities.
• One unified global standard. 
• Pervasive networks providing ubiquitous computing: The user can simultaneously be connected to several wireless access technologies and seamlessly move between them (See Media independent handover or vertical handover, IEEE 802.21, also expected to be provided by future 4G releases). These access technologies can be a 2.5G, 3G, 4G or 5G mobile networks, Wi-Fi, WPAN or any other future access technology. In 5G, the concept may be further developed into multiple concurrent data transfer paths. 
• Cognitive radio technology, also known as smart-radio: allowing different radio technologies to share the same spectrum efficiently by adaptively finding unused spectrum and adapting the transmission scheme to the requirements of the technologies currently sharing the spectrum. This dynamic radio resource management is achieved in a distributed fashion, and relies on software defined radio.
• High altitude stratospheric platform station (HAPS) systems.  

Features of 5G Networks Technology

1. 5G technology offer high resolution for crazy cell phone user and bi-directional large bandwidth shaping.
2. The advanced billing interfaces of 5G technology makes it more attractive and effective.
3. 5G technology also providing subscriber supervision tools for fast action.
4. The high quality services of 5G technology based on Policy to avoid error.
5. 5G technology is providing large broadcasting of data in Gigabit which supporting almost 65,000 connections. 
6. 5G technology offer transporter class gateway with unparalleled consistency.
7. The traffic statistics by 5G technology makes it more accurate.
8. Through remote management offered by 5G technology a user can get better and fast solution. 
9. The remote diagnostics also a great feature of 5G technology.
10. The 5G technology is providing up to 25 Mbps connectivity speed. 
11. The 5G technology also support virtual private network. 
12. The new 5G technology will take all delivery service out of business prospect. 
13. The uploading and downloading speed of 5G technology touching the peak. 
14. The 5G technology network offering enhanced and available connectivity just about the world  

Conclusion

• There are some other projects, which are undertaken ay 5G technologies. Here we want to mention that 3G mobiles are working these days, and 4G technologies are coming, but in future we are ready to face 5G technologies and some of its features we have presented in this paper.
