What is 5G All About?



You may hear about a new cellular communications standard every decade or so. Recently, the latest standard is causing a lot of buzz in the wireless industry. Yes, we are talking about 5G or the 5th generation standard for encoding and transmitting data over radio waves.

So, what is this 5G and what makes people so interested in it? We shall see what is 5G all about in this article and clear the air about this latest technology set to change the face of mobile communication and Internet.





Overview: The Generation of Wireless Technology



It all began with 1G. The G stands for generation of wireless technology. 1G was the first wireless technology that defined the data transmission speed. It was supposed to be an analog cellular technology and began in the 1980’s. Soon, each new generation has led to a breakthrough in encoding methods or ‘air interfaces’. This has made the new generation incompatible with the previous generation.

After 1G came the 2G technology. It included the CDMA, GSM, and TDMA. These were the first generation digital cellular technology. 2G was followed by 3G technology that introduced the world to EVDO, HSPA, and UMTS. 3G brought the speed of from 200 kbps down to few megabits/sec. Thus, setting base for the next generation wireless technology that is, 4G/LTE. It allowed high speed data transfer (hundreds of megabits per second) as well as better network for mobile communication.

We are now at the verge of the launch of 5G technology. It is expected to revolutionize the world of mobile communications and Internet. 5G is supposed to transmit 1 gigabit per second or even more.

What are the Advantages of 5G?


5G will bring forth many advantages and changes. It will not just improve the speed, capacity, and latency of network, but also help mobile operators to develop multiple virtual networks in a single physical network, that is, 5G network.

With this feature, mobile network connections will be able to support specific uses or Internet of Thing (IoT). For example, you can connect to a particular home appliance such as your home air conditioner or refrigerator wirelessly or even function self-driving without any glitches.

It will take several years before the 5G and services connection becomes a reality. However, it will help in generation and invention of new appliances as well new technologies for home, businesses, as well as industries and factories.

How Does 5G Work?


5G will require high-power and larger cell towers as compared to 4G. This is required for transmission of signals over longer distances. The 5G wireless signals will be transmitted via large numbers of small cell stations that are placed on light poles or terraces of high buildings or high rise towers. This is necessary as the millimeter wave spectrum band ranges from 30 GHz and 300 GHz on which the 5G depends on to provide high speeds. This band of spectrum can travel short distances and is affected by physical obstacles such as buildings or weather interferences.

Is 5G Ready to Reach Us?


5G has been vigorously pursued in four countries- the United States, South Korea, Japan, and China. The network operators from these countries are expected to spend billions of dollars for 5G capital expenses until year 2030.

5G requires 5G ready devices that can run on 5G network. It will be launched by the end of 2019 but will commercially available between 2020 and 2025. It is only by 2030 will 5G become a mainstream technology.

Types of 5G Services


There are two types of 5G services being developed by mobile operators. This includes:
  • 5G fixed a wireless broadband service that delivers internet access to homes and businesses. This is wireless connection that requires NRs in small cell sites near buildings that beam a signal to a receiver. This receiver is placed on rooftops nd windowsills. It will make it cheaper for the operators to deliver broadband services as they will no longer need fiber optic lines and cables.
  • 5G cellular services that delivers 5G cellular network. It is expected to roll out in 2019 or start of 2020 when 5G enabled devices are commercially available.

This is what 5G is all about. 5G will be launched by AT&T in 12 cities by the end of 2019. It will bring forth the focus to smarter and faster smartphones as well as creation of interesting and useful applications in the future. 5G will surely makes the future appear more interesting and exciting for us all.
