5G is the term used to describe the next-generation of mobile networks beyond LTE mobile networks. At least four major phone carriers in the US — AT&T, Verizon, T-Mobile, and Spring have solid plans to introduce their mobile 5G networks in 2019. AT&T has even started trials with utg5G mobile hotspots in 12 cities. Verizon is advertising a 5G home network (however, Verizon’s offering does not align with what standard bodies are defining as 5G).

The International Telecommunications Union (ITU) has released several reports on the standards for the 5G network that it refers to as the International Mobile Telecommunications (IMT)-2020 network.

The 3GPP is a mobile industry standards body that created its own standards for 5G New Radio specifications, published in December 2017. Both mobile operators and vendors participate in the 3GPP specification process.

According to ITU guidelines, 5G network speeds should have a peak data rate of 20 Gb/s for the downlink and 10 Gb/s for the uplink. Latency in a 5G network could get as low as 4 milliseconds in a mobile scenario and can be as low as 1 millisecond in Ultra Reliable Low Latency Communication scenarios. Not only will people be connected to each other but so will machines, automobiles, city infrastructure, public safety and more.

5G networks are also designed to have always-on capabilities and aim to be energy efficient by minimizing how much power a modem uses based on the amount of traffic going through it.

5G Will Integrate LTE

LTE Advanced Pro is foundational to the 5G network. While 5G can access the extremely high-frequency millimeter wave radio spectrum, there will also be spectrum sharing with the LTE wavelengths. The use of mmwaves bands will also be aided by existing LTE macro and small cell sites.

Self-organizing networks (SON) are also a key factor in reducing costs of installation and management of the network by simplifying operational tasks. Other technologies, such as coordinated multipoint, which lets operators have multiple sites simultaneously transmitting signals and processing signals, will play a part in limiting inter-cell interference.

Important Advantages

There are several advantages of 5G technology, some of the advantages have been shown in the picture, and many others are described below:

• High resolution and bi-directional large bandwidth shaping.

• Technology to gather all networks on one platform.

• More effective and efficient.

• Technology to facilitate subscriber supervision tools for the quick action.

• Most likely, will provide a huge broadcasting data (in Gigabit), which will support more than 60,000 connections.

• Easily manageable with the previous generations.

• Technological sound to support heterogeneous services (including private network).

Possible to provide uniform, uninterrupted, and consistent connectivity across the world.

Disadvantages of 5G Technology

Though, 5G technology is researched and conceptualized to solve all radio signal problems and hardship of mobile world, but because of some security reason and lack of technological advancement in most of the geographic regions, it has following shortcomings:

• Technology is still under process and research on its viability is going on.

• The speed, this technology is claiming seems difficult to achieve (in future, it might be) because of the incompetent technological support in most parts of the world.

• Many of the old devices would not be competent to 5G, hence, all of them need to be replaced with new one — expensive deal.

• Developing infrastructure needs high cost.

• Security and privacy issue yet to be solved.

Applications of 5G

Some of the significant applications are – Because of the IPv6 technology, visiting care of mobile IP address will be assigned:

• as per the connected network and geographical position.

• Its application will make world real Wi Fi zone.

• Its cognitive radio technology will facilitate different version of radio technologies to share the same spectrum efficiently.

• Developing infrastructure needs high cost.

• Its application will facilitate people to avail radio signal at higher altitude as well.
