The term 5G is generally referred to as the fifth generation cellular network technology that provides broadband access. It is a kind of next generation of mobile networks ahead LTE mobile networks. 5G mobile cellular communications system provides a far high level of performance as compared to the previous generations and is derived from 1 to 2, 3, 4 and currently 5G. Many of the mobile companies have plans to offer their mobile 5G networks in the present year.
How is 5G technology different?
It is researched that 5G technology is completely different. Apart from the speed enhancements, 5G is conventional to release a hefty IoT ecosystem in which networks can serve communication needs for billions of connected devices with the right trade-offs between speed, intermission and price. The earlier systems had derived more by what could be done with the current technology. But this new one is being driven by specific uses ad functions. Why 5G has been herded by the requirement to provide pervasive connectedness for applications distinct as automotive communications, remote control with haptic style feedback. Huge video downloads, and very low data rate applications like remote sensors.
What is 5G?
5G is like an investment for the next decade and the G here stands for the generation of wireless technology. The earlier generations has been technically defined by their speed of data communication and break in encoding methods. If we talk about the previous generation, 1G was analog cellular, 2G technologies were the first generation of digital cellular technologies. 3G came up with a speed from 200kbps to few megabits per second and 4G were the antagonistic leap forward which can scale up to hundred of megabits level speeds. 5G networks are digital cellular networks in which the service area covered by providers is divided into small geographical areas known as cells. The analog signals representing sounds and images are downloaded in the phone which is converted by an analog to digital converter and broadcasted as a stream of bite. All the 5G wireless devices in a cell communicate by radio waves with a local antenna array and low power automated transceiver in the cell.
According to some researches, the network speed of 5G network should have spike data rate of 20 Gb/s for download purpose and 10 Gb/s for the uplink. It enables the connectivity of not only people but also of machines, automobiles, public safety or city infrastructure. They are designed to have on capabilities and have motive to be energy effective. The performance of 5G includes the speed and dormancy and like other networks, 5G uses a system of cell sites that divide their territory into sectors and send encoded data by the means of radio waves.
How it works?
Each cell site in 5G network must be connected to a network backbone, either through wired or wireless connection. This network uses a type of encoding called OFDM which is similar to encoding that is being used by 4G networks. The air interface is designed for a lower intermission and greater flexibility. The new systems are also created so that they can conduct much larger channels than the earlier 4G networks so that it can carry high speeds. 5G channels can up to 100 MHz much greater than 4G channels and has expansive highway. But 5G networks need to be much smarter than the earlier systems with their goal to have far higher speeds and far higher capacity per sector at low latency as compared to 4G. The 5G technology is driven by 8 spec requirements which are described below.
- Up to 10 Gbps data rate which is a huge improvement over 4G networks
- 1-millonsecond remission
- 1000X bandwidth per unit area
- Up to 100X number of connected devices per unit area as compared to 4G LTE
- 99.999% availability
- 100% coverage
- 90% reduction in network energy usage
- Battery life up to 10 year for low power IoT devices
5G communication system
The 5G mobile cellular communication will be a major advance in the area of mobile communications which is operated by the people on a general basis. In order to accomplish this, a new radio access network and new core network are needed to gain the required performance.
- 5G New Radio
It is the name of new 5G radio access network consisting of the different elements required for the new access network. By the means of a malleable technology, the system will be able to respond to different and changing needs of mobile users.
- 5G NextGen Core Network
The eventual motive of this is to have a network that is capable enough to handle the higher data volumes although being able to provide much lower level of latency.
The defining of 5G is due because of its architecture and distribution. The major demand of its initialization due to the video traffic people are facing on a regular basis. This new generation of cellular network came with new uses. It will be focused on IoT and critical communication applications. Few are the use cases of this technology are mentioned below.
- Fixed Wireless Access
- Improved mobile broadband with fall back from 4G
- Massive M2M/IoT
- Low-latency IoT critical communications
The current 5G technology has come up with some of the major issues along with the benefits. Let’s discuss them in detail.
- Interference Issues: The interference will occur and will be possibly powerful without effective controls. Interference to satellite operations impairs the numerical weather prediction performance due to which suggestions of controlling this is made.
- Health Concerns: The development of this technology has stoked fear that 5G radiation could have adverse health effects.Health concerns related to radiation from cell phone and towers has already been reported negative effects on human. Apart from 4G technology, 5G has some more new issues due to high microwave frequencies. More information about 5g technology can be collected from here.
5G is initiated as a home internet service due to increased demand of cell phones. 5G home internet has huge capacity as compared to 4G, multiple connections, easy for carriers to roll out than fiber optic lines. Along with this, 5G is also crucial for industrial uses, technology like driverless cars and many more. As a summary, the concept of speed, quick response time and IoT performance by 5G networks is able to bring change in the world.
