Introducing 5G Network


5G is the fifth generation of wireless communications technologies supporting cellular data networks. 5G communication requires the use of communications devices (mostly mobile phones) designed to support the technology.
The frequency spectrum of 5G is divided into millimeter waves, mid-band, and low-band. Low-band uses a similar frequency range as the predecessor, 4G. 5G millimeter wave is the fastest, with actual speeds often being 1–2 Gbit/s down. Frequencies are above 24 GHz, reaching up to 72 GHz, which is above the extremely high-frequency band's lower boundary. The reach is short, so more cells are required. Millimeter waves have difficulty traversing many walls and windows, so indoor coverage is limited.

5G mid-band is the most widely deployed, in over 30 networks. Speeds in a 100 MHz wide band are usually 100–400 Mbit/s down. In the lab and occasionally in the field, speeds can go over a gigabit per second. Frequencies deployed are from 2.4 GHz to 4.2 GHz. Sprint and China Mobile are using 2.5 GHz, while others are mostly between 3.3 and 4.2 GHz. Many areas can be covered simply by upgrading existing towers, which lowers the cost. Mid-band networks have better reach, bringing the cost close to the cost of 4G. 5G low-band offers similar capacity to advanced 4G.

 HOW IT WORKS

5G networks are digital cellular networks, in which the service area covered by providers is divided into small geographical areas called cells. Analog signals representing sounds and images are digitized in the telephone, converted by an analog to digital converter and transmitted as a stream of bits. All the 5G wireless devices in a cell communicate by radio waves with a local antenna array and low power automated transceiver (transmitter and receiver) in the cell, over frequency channels assigned by the transceiver from a pool of frequencies that are reused in other cells. The local antennas are connected with the telephone network and the Internet by a high-bandwidth optical fiber or wireless backhaul connection. As in other cell networks, a mobile device crossing from one cell to another is automatically "handed off" seamlessly to the new cells

Step by Step of Becoming an Ethical Hacker

INTRODUCTION : What is Hacking? Hacking of computerized electronic machines and networks is considered as the biggest national threat by the security services and the intelligence agencies of many countries. Hacking was once considered as a harmless activity to improve  an existing computerized machine by identifying its strength and weakness. But now hacking is more or less of a crime than any other. In some countries hacking is considered on the same level as terrorism. It is condemned large by the world governments. Types of Hacking 1. White Hat Hacking ( Ethical Hacking) 2. Black Hat Hacking ( Crackers) Ethical hacking : An Ethical hacking  is a process  of building , fortifying, securing a computerized machine and networks by knowing its strength and weakness .  To do that, the ethical hacker must get into the mindset of whoever is trying to break into their system.  They will thoroughly check their system for weaknesses, and figure out how they...

Penetration Testing

Penetration test, which  is also known as pentest, is an authorized simulated cyberattack on a computer system, which is aimed at evaluating the security of the system. The test is performed to identify both weaknesses (also referred to as vulnerabilities), including the potential for unauthorized parties to gain access to the system's features and data, as well as strengths,enabling a full risk assessment to be completed. Types of Web Penetration Testing Web applications can be penetration tested in 2 ways. Tests can be designed to simulate an inside or an outside attack. 1) Internal Penetration Testing – As the name suggests, the internal pen testing is done within the organization over the LAN, hence it includes testing web applications hosted on the intranet. This helps in finding out if there could be vulnerabilities which exist within the corporate firewall. We always believe attacks can happen only externally and many a time’s internal Pentest is overloo...
