5g road to 5g (the future of wireless communication) technology
Wireless phone standards have a life of their own. You can tell, because they are spoken of reverently in terms of generations. There's Great-Granddad, whose pioneering story pre-dates cellular; Grandma and Grandpa 1G, or analog cellular, Mom and Dad 2G, or digital cellular; 3G wireless, 4G, 5G and so on. Now in this survey report, I am going to describe about these generation of network.
1. Introduction:
The cellular networks are evolving through several generations (figure1). The first generation (1G) wireless mobile communication network was analog system which was used for public voice service with the speed up to 2.4kbps. The second generation (2G) is based on digital technology and network infrastructure. As compared to the first generation, the second generation can support text messaging. Its success and the growth of demand for online information via the internet prompted the development of cellular wireless system with improved data connectivity, which ultimately lead to the third generation systems (3G).
3G systems refer to the developing technology standards for the next generation of mobile communications systems. One of the main goals of the standardization efforts of 3G is to create a universal infrastructure that is able to support existing and future services. This requires that the infrastructure be designed so that it can evolve as technology changes, without compromising the existing services on the existing networks. Separation of access technology, transport technology, service technology and user application from each other make this demanding requirement possible.
The 4th Generation (4G) wireless mobile internet networks are research items in academy, which will integrate current existing 3G cellular networks (i.e., OFDM, CDMA2000, WCDMA and TD_SCDMA) and Wi-Fi (i.e. Wireless LAN) networks with fixed internet to support wireless mobile internet as the same quality of service as fixed internet, which is an evolution not only to move beyond the limitations and problems of 3G, but also to enhance the quality of services, to increase the bandwidth and to reduce the cost of the resource.
The 5th wireless mobile multimedia internet networks can be completed wireless communication without limitation, which bring us perfect real world wireless – World Wide Wireless Web (WWWW). 5G is based on 4G technologies, which is to be revolution to 5G. During this processing, there are two kind of problems need to be solved. The first is wider

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

- 7. 2.5G • 2.5G i.e. G or GPRS which stands for General Packet Radio Services. • This is the technology from where data or Internet pack was started. • 2.5G maximum speed is 141Kbps and it is theoretical maximum.
- 8. 2.75G • EDGE or E, it stands for Enhance data rate for GPRS Evolution. • As cleared from the name it is the enhancement in speed of GPRS, which increases the speed of GPRS from 141Kbps to 473Kbps. • Its speed is more because of the change in modulation technique.
- 11. 3G • Third Generation of Cellular communication was 1st launched by NTT Docomo, Japan in 1999 due to which it was also named as Release 99 or R’99. • It provides the speed maximum of 2 Mbps. • Multiple applications can be run at the same time like Video call, internet surfing, games, online banking etc… • Provides good voice quality. • Comes with a feature of providing video quality with less delay. • Roaming is possible. • It is also the digital technology that works on the technique named WCDMA (Wideband Code Division Multiple Access
- 12. HSPA (H) • HSPA stands for High Speed Packet Access also called as 3.5G. • Comes to provide enhancement in speed i.e. maximum up to 14.4Mbps for Downlink and 5.76 for Uplink.
- 17. 4G
- 18. If we assume a single FLASH is 3G network
- 19. Then, 10X is 4G network.
- 20. 4G • 4G stands for 4th Generation of Cellular communication. • It was developed in 2010. • Its system is named as LTE i.e. Long Term Evolution. • Faster and more Reliable • Capable of providing speed between 100 Mbps - 1Gbps • It is purely packet Switched network. • Low Cost, High QoS and High Security
- 23. 5G • Complete wireless communication with almost no drawbacks. • It is highly supportable to wwww (wireless world wide web). • More Speed (in Gbps), More Capacity • More clear Audio/Video. • Less Delay • It will be available in the market by 2020 at affordable cost with more reliability than previous phones. • More Secure and Safe for Public.
