Think of 5G as divided into two parts. One is low-frequency 5G and high-frequency 5G. Low-frequency networks will use the same radio bands that current technology uses, but changes to signal programming and broad channel bands will allow for speeds up to 50% better than the best 4G LTE network has to proposal today. Networks using these changes will also still be able to have the same variety that they currently have, which means no additional cell sites are needed to maintain the same network footprint. Some new parts will need to be installed at current sites, and carriers are getting all things 5G-ready in preparation. 5G is used to describe the next-generation of mobile networks past LTE mobile networks. The four major phone carriers in the US AT&T, Verizon, T-Mobile, and Sprint have powerful plans to introduce their mobile 5G networks in 2019. AT&T has started hearings with 5G mobile hotpots in 12 cities. Verizon is presenting 5G home networking.

- Technological sound to care mixed services (including private network).
- Possible to provide even, uninterrupted, and consistent connectivity across the world.
However, 5G knowledge is investigated and abstract to solve all radio signal hitches and poverty of mobile world, but because of some security reason and shortage of technological progression in most of the geographic regions, it has following shortcomings:
- Technology is still under way and study on its capability is going on.
- The speed of this technology is requesting looks difficult to realize in future, it might be because of the useless technological care in most parts of the world.
- Many of the ancient policies would not be competent to 5G, hence, all of them need to be changed with new one — expensive deal.
- Developing infrastructure needs extra cost.
- Security and privacy problem yet to be solved.
Challenges
There are many tests to address when we move to 5G standard which burdens much higher data rate, ultra-low inexpression, high dependability and security. We know, fourth group wireless communication technology LTE and LTE progressive has already been organized all over the world. The fifth generation 5G wireless technology needs a new standard to support ultra-fast, low inexpression facilities to customers.
Frequency Bands
Present LTE system does with more than 50 frequency groups which are below 3.6 GHz range. One of the frequency applicants for early distribution of 5G is sub-6 GHz range. Unlicensed band under 6 GHz (600 MHz and between 3.5 GHz and 6 GHz) will be used for first generation of 5G systems.
Huge Data Volume
As the machinery developments, the data volume of each network also increases each year and the movement is increasing.
