Fifth-generation (5G) wireless networks are the latest evolution in cellular technology, designed to increase the speed and responsiveness of wireless networks. With 5G, data transferred over wireless broadband connections can travel at speeds of up to 20 Gbps by some estimates – surpassing the speeds of wired networks – while creating very low latency. with only 1ms or less for applications that require real-time responsiveness. 5G will also enable increased amounts of data to be transmitted over wireless systems with support for wider bandwidth and more advanced antenna technology.

In addition to speed, capacity, and latency improvements, 5G also offers network management features, including network slicing, which allows mobile operators to create multiple virtual networks within a physical 5G network. physical. This capability will enable wireless network connections that support specific needs or business models and can be sold on a service basis. For instance, a self-driving car would require a network layer that provides ultrafast, low-latency connections so a car can navigate in real time. However, a home appliance can be connected through a slower network connection, consuming less power because the high performance issue is not important. With Inteof Things (IoT), it is possible to use only secure and data-only connections.

5G networks and services will be rolled out in phases over the next few years to meet the growing reliance on mobile devices and internet connectivity. Overall, 5G is expected to create a host of new applications and business models as the technology rolls out.

How does a 5G wireless network work

?A wireless network consists of “cells” divided into zones that send data over radio waves. 4G LTE (Long-Term Evolution) technology will provide the foundation for 5G. Unlike 4G, which requires large, high-power cell towers to transmit signals over longer distances, 5G wireless signals will be transmitted through a large number of small cell stations located in places like lamp post or roof. The use of many small cells is necessary because millimeter wave spectrum – the spectrum between 30 GHz and 300 GHz on which 5G relies for high speeds – can only travel over short distances and is subject to weather and interference interference. obstacles such as buildings.

Previous generations of wireless technology used lower frequency bands. To offset the millimeter wave challenges associated with distance and interference, the wireless industry is also looking at using lower frequency spectrum for 5G networks so that network operators can use the spectrum they already have. ownership to build new networks. However, the lower frequency spectrum achieves greater distances but has lower speed and power than millimeter waves.

What is the status of 5G deployment

?Wireless network operators in four countries – the United States, Japan, South Korea and China – are largely driving the construction of networks. First 5G. They are expected to spend billions of dollars on 5G investment costs through 2030, according to Technology Business Research Inc., although it is unclear how 5G service will generate a return on that investment. Developing applications and business models that leverage the benefits of 5G can address operators’ revenue concerns.

At the same time, standards bodies are working on universal 5G equipment standards. The 3rd Generation Partnership Project (3GPP) approved the new 5G Radio (NR) standard in December 2017 and is expected to complete the 5G cellular core standard required for 5G mobile services. at the end of 2018. 5G radio systems are not compatible with 4G radios, but network operators who have invested in a wireless network recently can upgrade to the new 5G system through software instead of purchasing equipment. be new.

With 5G wireless device standards almost complete and the first 5G compatible smartphones and related wireless devices hitting the market in 2019, 5G applications will begin to emerge. from 2020 to 2025, as predicted by Technology Business Research. By 2030, 5G services will become mainstream and are expected to shift from virtual reality (VR) content delivery to automated vehicle navigation enabled by real-time communication capabilities. real (RTC).

What kinds of 5G wireless services will be offered

?Carriers are developing two types of 5G services.

5G fixed wireless broadband service provides internet access to homes and businesses without the need for a traditional wired connection. To do that, network operators deploy NRs in small-scale cellular cells near buildings to broadcast the signal to a rooftop receiver or amplified window sill on premises. Fixed broadband services are expected to help operators provide broadband services to homes and businesses less expensively. This method eliminates the need to deploy fiber optic lines to every residence. Instead, operators simply install fiber optic cables into mobile cells and customers receive broadband service through wireless modems located in their residential or business premises.

The 5G mobile service will provide users with access to the operator’s 5G mobile network. These services will begin rolling out in 2019, when the first 5G-enabled (or compatible) devices are expected to hit the market during this time. The delivery of mobile services also depends on the completion of 3GPP mobile core standards by the end of 2018.
