The year 2020 will be the 5th Generation Network’s year, because the plan has been done to roll out and the work is in full swing. All organizations, operators, network vendors are putting their much needed efforts to make the 5G vision into reality.
5G as a technology is expected to enable a fully mobile and connected society and to empower socio-economic transformations in countless ways many of which are unimagined today, including those for productivity, sustainability and well-being.
5G technology is driven by 8 specification requirements
- Up to 10Gbps data rate – > 10 to 100x improvement over 4G and 4.5G networks
- 1-millisecond latency
- 1000x bandwidth per unit area
- Up to 100x number of connected devices per unit area (compared with 4G LTE)
- 999% availability
- 100% coverage
- 90% reduction in network energy usage
- Up to 10-year battery life for low power IoT devices
- Low System Latency
When is 5G coming?
South korea which is at present the highest speed providing country, too proclaims to be the first 5G network country in upcoming year. Huawei has secured 50 5G commercial contracts globally, of which 28 were signed in Europe.
- ITU-R launched “IMT for 2020 and beyond” in 2012, setting the stage for 5G.
- Japan and Korea started to work on 5G requirements in 2013.
- NTT Docomo did first 5G experimental trials in 2014.
- Samsung, Huawei and Ericsson started prototype development in 2013.
- South Korean SK Telecom plans to demo 5G in 2018 at the Pyeongchang winter Olympics.
- Ericsson and TeliaSonera plan to make commercial service available in Stockholm and Tallinn by the end of 2018.
- Japan target is to launch 5G for the 2020 Tokyo summer Olympics.
Applications of 5G technology
5G technology will power wide range of future industries from retail to education, transportation to entertainment and smart homes to healthcare. It will make mobile more essential than it is today.
High-speed mobile network
5G will revolutionize the mobile experience with supercharged wireless network, which can support up to 10 to 20 GBPS of data download speed. It is equivalent to a fiber optic Internet connection accessed wirelessly. Compared to conventional mobile transmission technologies, voice and high-speed data can be simultaneously transferred efficiently in 5G. Low latency is one of the most important features of 5G technology which is significant for autonomous driving and mission critical applications. 5G networks are capable of latency less than a millisecond.
Entertainment and multimedia
Analysts found that 55 percentage of mobile Internet traffic has been used for video downloads globally in 2015. This trend will increase in future and high definition video streaming will be common in future. 5G will offer a high definition virtual world on your mobile phone. High speed streaming of 4K videos only takes few seconds and it can support crystal clear audio clarity.
Internet of Things – Connecting everything
Internet of Things (IoT) is another broad area for development using supercharged 5G wireless network. Internet of Things will connect every objects, appliances, sensors, devices and applications into Internet. The IOT related applications of 5G technology are given below,
- Smart Home
- Logistics and shipping
- Smart cities
- Industrial IoT
- Smart farming
- Fleet management
- Healthcare and mission critical applications
- Autonomous Driving
- Drone Operation
- Security and surveillance
Advantages of 5G
- There are numerous advantages of 5G over 4G network, to understand that some of them are as follows:
- 5G uses the rarely used radio millimetre bands in the 30 GHz to 300 GHz range. Current 4G networks operate on frequencies below 6GHz. Testing of 5G range in mm Wave has produced results approximately 500 meters from the tower.
- Using small cells, carriers using millimetre wave for the deployment of 5G can improve overall coverage area. With Beamforming, small cells can boost coverage with low latency.
- Low latency is one of 5G’s most important features. This makes the technology suitable for applications that require rapid responsiveness. To reduce response times, 5G uses a scalable orthogonal frequency-division multiplexing (OFDM) framework.
- 5G benefits greatly from this and can have latency as low as one millisecond with realistic estimates to be around 1-10 milliseconds. 5G is estimated to be 60 to 120 times faster than the average 4G latency.
- With speeds of up to 10 Gbps, 5G is set to be as much as 10 times faster than the 4G network.
Disadvantages of 5G
- Although, 5G technology has been researched and conceptualized to solve all radio signal problems and hardship of mobile world, there are some security reasons and lack of technological advancement in most of the geographic regions, it has below disadvantages
- Technology is still under process and research on its feasibility is going on.
- Speed, this technology claiming seems difficult to be achieved (in future, it might be) because of the lack of technological support in most parts of the world.
- Most of the old devices are not competent to 5G. therefore, all of them should be replaced with new one — expensive deal.
- Developing infrastructure requires high cost.
- Security and privacy issue is yet to be solved.
