what does the g stand for in 5g ?
The “G” related with cellular networks stands for generation. 5G is the fifth and newest generation of cellular wireless network technology
5G Wireless: 5th generation wireless Technology
- Complete wireless communication with almost no limitations
- Can be called REAL wireless world
- Has incredible transmission speed
- Concept is only theory not real
What does it offer?
- Worldwide cellular phones
- Extraordinary data capabilities
- High connectivity
- More power & features in hand held phones
- Large phone memory, more dealing speed, more clarity in audio & video
5G:
- Next major phase of mobile telecommunication & wireless system
- 10 times more capacity than others
- Expected speed up to 1 Gbps
- More faster & reliable than 4G
- Lower cost than previous Generations
Basic Architecture of 5G
- Application Layer, Presentation layer ->Application(Service)
- Session Layer , Transport Layer -> Open Transport Protocol
- Network Layer -> Upper network layer
- Data link Layer, Physical Layer -> Lower network layer Open Wireless Architecture
Open Wireless Architecture OWA
- OSI layer l & OSI layer 2 define the wireless technology
- For these two layers the SG mobile network is likely to be based on Open Wireless Architecture (OWA)
- Physical layer+ Data link layer= OWA
Network Layer
- All mobile networks will use mobile IP
- Each mobile terminal will be FA (Foreign Agent)
- A mobile can be attached to several mobiles or wireless networks at the same time
- The fixed 1Pv6 will be implemented in the mobile phones
- Separation of network layer into two sub-layers:
(i) Lower network layer (for each interface)
(ii) Upper network layer (for the mobile terminal)
Open Transport Protocol OTP
- Wireless network differs from wired network regarding the transport layer
- In all TCP versions the assumption is that lost segments are due to network congestion
- In wireless, the loss is due to higher bit error ratio in the radio interface
- 5G mobile terminals have transport layer that is possible to be downloaded & installed – Open Transport Protocol (OTP)
- Transport layer+ Session layer= OTP
Application service Layer
- Provides intelligent QoS (Quality of Service) management over variety of networks
- Provides possibility for service quality testing & storage of measurement information in information database in the mobile terminal
- Select the best wireless connection for given services
- QoS parameters, such as, delay, losses,BW, reliability, will be stored in DB of 5G mobile
- Presentation layer+ Application layer= Application Hardware & Software of 5G
5G Hardware:
- Uses UWB (Ultra Wide higher BW at low energy levels )
- B W is of 4000 Mbps, which is 400 times faster than today’s wireless networks
- Uses smart antenna
- Uses CDMA (Code Division Multiple Access)
5G Software:
- 5G will be single unified standard of different wireless networks, including LAN technologies, LAN/WAN, WWWW-World Wide Wireless Web, unified IP & seamless combination of broadband
- Software defined radio, encryption, flexibility, Anti-Virus
Features of 5G
- High resolution for crazy cell phone users
- Bi-directional large BW
- Less traffic
- 25 Mbps connectivity speed
- Enhanced & available connectivity just about the world
- Uploading & Downloading speed of 5G touching the peak (up to 1 Gbps)
- Better & fast solution Features
- High quality service based on policy to avoid error
- Support virtual private networks
- More attractive & effective
- Provides subscriber supervision tools for fast action
Advantages of 5G
- Data BW of 1 Gbps or higher
- Globally accessible
- Dynamic information access
- Available at low cost
Applications of 5G
- Wearable devices with Al (Artificial Intelligence) capabilities
- Pervasive (Global) networks
- Media independent handover
- Radio resource management
- VoIP (Voice over IP) enabled devices
- With 6th sense technology
Evolution from 1G to 5G
- 1G
- 2G
- 3G
- 4G
- 5G
1G – 1st Generation Technology
Developed in 1980s & completed in early 1990s
- Base on analog system
- Speed up to 2.4 kbps
- AMPS (Advance Mobile Phone System) was Launched by the US & it was the 1 G mobile system
- Allows user to make voice calls in 1 country
2G-2nd Generation Technology
- Developed in late 1980s & completed in late 1990s
- Based on digital system
- Speed up to 64 kbps
- Services such are digital voice & SMS with More clarity
- Semi global facility
- 2G are the handsets we are using today, with 2.SG having more capabilities
3G-3rd Generation Technology
- Developed between late 1990s & early 2000s until present day
- Transmission speed from 125 kbps to 2 Mbps
- Superior voice quality
- Good clarity in video conference
- E-mail, PDA, information surfing, on-line shopping/banking , games, etc.
- Global roaming
4G -4th Generation Technology
- Developed in 2010
- Faster & more reliable
- Speed up to 100 Mbps
- High performance
- Easy roaming
- Low cost
Conclusion
- 3G- Operator Centric,
- 4G- Service Centric whereas
- 5G- User Centric
- We have proposed 5G wireless concept Designed as an open platform on Different layers
- The new coming 5G technology will be Available in the market at affordable Rates, high peak future & much reliability Than preceding technologies
