Q. What are the benefits of 5G?

5G is the fifth-generation wireless technology for digital cellular networks that have started widespread deployment in 2019. By previous standards, the areas covered are divided into "cells" regions, serviced by individual antennas. Virtually every major telecommunications service provider in the developed world is deploying antennas or intends to deploy them soon. The frequency spectrum of 5G is divided into millimeter waves, mid-band, and low-band. The low-band predecessor uses the same frequency range as 4G.

Analogous Definition

5G networks are digital cellular networks, in which the service area covered by the providers is divided into smaller geographical areas called cells. Analog signals representing sounds and images are digitized digitally in the telephone, converted from analog to digital converter and transmitted as a stream of bits. All 5G wireless devices in the cell communicate by radio waves with a local antenna array and low power automatic transceiver (transmitter and receiver) in the cell, a frequency assigned by the transceiver from a pool of frequencies reused in other cells. On channels. Local antennas are connected to the telephone network and the Internet by a high-bandwidth optical fiber or wireless backhaul connections. Like other cell networks, a mobile device that crosses from one cell to another automatically "goes off", which is near the new cell. Verizon and some others are using millimeter waves. [3] Millimeter waves have a smaller range than microwaves, so cells are limited to smaller sizes. Millimeter waves also have more difficulty passing through the construction of walls. Millimeter-wave antennas are smaller than larger antennas used in previous cellular networks. They are only a few inches (several centimeters) long. Another technique used to increase the data rate is mass MIMO (multiple-input multiple-output). Each cell will have multiple antennas communicating with the wireless device, which are received by multiple antennas in the device, thus multiple bitstreams of data will be transmitted simultaneously, in parallel. In a technique called beamforming, the base station computer would continuously calculate the best route for radio waves to reach each wireless device, and to work together as phased arrays to create beams of millimeter waves to reach the device. We will hold several antennas. More than 20 networks are deployed using the middle band spectrum, ranging from 2.4 to 4.2 GHz. Mid-band networks have better accessibility, making the cost closer to the cost of 4G. Universal mobile telecommunications system, built and modified by 3GPP. The family is a complete modification from GSM in terms of encoding methods and hardware, although some GSM sites can be retrofitted to broadcast in the UMTS / W-CDMA format. Low-band 5G in T-Mobile USA and AT&T December 2019 Are announced. 

The performance, reach and cost will be similar to 4G in the same band when the 5G system is fully developed and can reach more carrier frequencies. The new 5G wireless device also has 4G LTE capability, as with the new network cell Use 4G to establish relationships, as well as places where 5G access is not available. 5G can support up to one million devices per square kilometer, while 4G supports only 100,000 devices per square kilometer

5G is a new type of network: a platform for innovations that will not only enhance today's mobile broadband services, but also support the vast diversity of devices and services and improve performance, efficiency, and connect new industries to mobile Will expand the network. Cost. 5G will redefine a wide range of industries with services ranging from retail to education, transportation to entertainment, and everything in between. We see 5G as a technology that is as transformative as automobiles and electricity.

Through a historical 5G economy study, we found that the full economic impact of 5G will be felt worldwide by 2035, supporting a wide range of industries and possibly producing goods and services valued at $ 12 trillion.

The study also showed that the 5G value chain (OEMs, operators, content creators, app developers, and consumers) can generate up to $ 3.5 trillion in total revenue by 2035 alone and 22 million jobs, or one from each Can support more jobs. The person in Beijing, China. Of course, many emerging and new applications are yet to be fully defined or are still known today. That is why only time will tell what the full "5G effect" is going to be.
