 5G (5th generation mobile networks or 5th generation wireless systems) denotes the proposed next major phase of mobile telecommunications standards beyond the current 4G/IMT-Advanced standards. 5G planning includes Internet connection speeds faster than current 4G, and other improvements.

 

The future of mobile communications is likely to be very different to that which we are used to today. While demand for mobile broadband will continue to increase, largely driven by ultra high definition video and better screens, we are already seeing the growing impact of the human possibilities of technology as the things around us become ever more connected.

5G cellular systems overview

As the different generations of cellular telecommunications have evolved, each one has brought its own improvements. The same will be true of 5G technology.

  • First generation, 1G:   These phones were analogue and were the first mobile or cellular phones to be used. Although revolutionary in their time they offered very low levels of spectrum efficiency and security.
  • Second generation, 2G:   These were based around digital technology and offered much better spectrum efficiency, security and new features such as text messages and low data rate communications.
  • Third generation, 3G:   The aim of this technology was to provide high speed data. The original technology was enhanced to allow data up to 14 Mbps and more.
  • Fourth generation, 4G:   This was an all-IP based technology capable of providing data rates up to 1 Gbps.

Any new 5th generation, 5G cellular technology needs to provide significant gains over previous systems to provide an adequate business case for mobile operators to invest in any new system.

Facilities that might be seen with 5G technology include far better levels of connectivity and coverage. The term World Wide Wireless Web, or WWWW is being coined for this.

For 5G technology to be able to achieve this, new methods of connecting will be required as one of the main drawbacks with previous generations is lack of coverage, dropped calls and low performance at cell edges. 5G technology will need to address this.

 

G is the hottest topic in wireless circles today. Many of the field’s most celebrated researchers and highest-paid executives are focused on forging this ultra-fast and high-bandwidth successor to 4G LTE. Among them, this opportunity to construct the next generation of wireless is often compared to Halley’s Comet: It comes around only once or twice in a person’s career.  

 

5G enthusiasts say the widely heralded future wireless network will deliver lightning-quick mobile data speeds with virtually unlimited capacity, blanket cities with high-quality Internet access, provide low bandwidth IoT connections to billions of devices, and even enable autonomous driving. But the industry has only just begun to set standards that will define 5G’s capabilities and launch very early trials that will establish its parameters.

 

But in many cases, the term “5G” is bandied about as a panacea that already exists. That’s why Seizo Onoe, CTO of NTT DOCOMO, Japan’s largest mobile carrier, is traveling around to conferences trying to keep everyone’s expectations in check. “In the early 2000s, there was a concrete 4G technology but no one called it 4G,” Onoe laments. “Today, there are no contents of 5G but everyone talks about 5G, 5G, 5G.”

 

5G is the biggest opportunity ever for our industry. We need to make sure there is one global standard that does not fragment terminal vendors and prevent the global scale that we have become used to with LTE. It is a global industry and teamwork is needed to achieve success.

Why 5G from Ericsson?

  • Complete knowledge and experience built over four generations of network technology
  • A complete end-to-end vendor service
  • Active in developing major new use cases
  • A leading position in all domains required for 5G: radio, edge/core, OSS/BSS and services

 

What will happen in the next five years?

Industries will be transformed by new capabilities brought on by 5G. Examples of these capabilities include:

  1. The ability to download a full-length HD movie in seconds.
  2. The quick reaction time (low latency) to enable remote surgery.
  3. The ability to spin up virtual networks on-demand with network slicing.
  4. Battery lifetimes beyond 10 years for remote cellular devices.

 

5G Mobile Wireless Technology

- preliminary details and information about the wireless technology being developed for 5th generation or 5G mobile wireless or cellular telecommunications systems

With the 4G telecommunications systems now starting to be deployed, eyes are looking towards the development of 5th generation or 5G technology and services.

Although the deployment of any wireless or cellular system takes many years, development of the 5G technology systems is being investigated. The new 5G technologies will need to be chosen developed and perfected to enable timely and reliable deployment.

The new 5th generation, 5G technology for cellular systems will probably start to come to fruition around 2020 with deployment following on afterwards.



5G mobile systems status

The current status of the 5G technology for cellular systems is very much in the early development stages. Very many companies are looking into the technologies that could be used to become part of the system. In addition to this a number of universities have set up 5G research units focussed on developing the technologies for 5G

In addition to this the standards bodies, particularly 3GPP are aware of the development but are not actively planning the 5G systems yet.

Many of the technologies to be used for 5G will start to appear in the systems used for 4G and then as the new 5G cellular system starts to formulate in a more concrete manner, they will be incorporated into the new 5G cellular system.

The major issue with 5G technology is that there is such an enormously wide variation in the requirements: superfast downloads to small data requirements for IoT than any one system will not be able to meet these needs. Accordingly a layer approach is likely to be adopted. As one commentator stated: 5G is not just a mobile technology. It is ubiquitous access to high & low data rate services.

5G specifications

Although the standards bodies have not yet defined the parameters needed to meet a 5G performance level yet, other organisations have set their own aims, that may eventually influence the final specifications.

Typical parameters for a 5G standard may include:

Suggested 5G Wireless Performance
Parameter Suggested Performance
Network capacity 10 000 times capacity of current network
Peak data rate 10 Gbps
Cell edge data rate 100 Mbps
Latency < 1 ms

These are some of the ideas being put forwards for a 5G standard, but they are not accepted by any official bodies yet.
