Today we’re going to talk about what 5G is going to enable and what are the key features of 5G. With its fundamental capabilities, 5G is shifting the perception of what’s possible as we usher in the fourth industrial revolution.
Mobile communication has profoundly changed people's lives, but people's pursuit of higher-performance mobile communication has never stopped. To cope with the explosive growth in subscribers’ needs for mobile data traffic, massive device connections, various emerging new services and other applications scenarios, the fifth-generation mobile communication (5G) system has emerged as the times require. But 5G is not just only the next generation of "G", 5G will completely change the key industries and nurture a new mobile ecosystem.
What new opportunities will 5G bring?
5G offers enormous potential for both consumers and industries. As well as the prospect of being considerably faster than existing technologies, 5G holds the promise of applications with high social and economic value, leading to a ‘hyper-connected society’ in which mobile will play an ever more critical role in people’s lives. We call 5G is the “Multiple technologies work together to create a pervasive connection. Innovation and strategies for optimal network economics. Evolutionary technology supporting the new business model.”
Key technical indicators for 5G
First, the network air interface will support the channels with a bandwidth higher than 10Gbps. But this refers to the transmission capacity of the entire chain, rather than the download speed a single user can getting. Second, the network will be able to provide access to more than one million devices in a square kilometer range. Third, 5G can provide the lower latency and higher reliable communication than 4G. Different 5G applications need different latency requirements. For example, in the medical and health, public safety rescue applications, there are ultra-low latency requirements, which must less than 1ms. But in a smart home need less than 10ms.
As we know, 5G has a new spectrum, which leads to a high-frequency band communication. This higher frequency band could meet the high speed, and high capacity requirements.5G have the latest air interface to support large-scale equipment interoperability and improve the efficiency of the spectrum. 5G will have new network architecture, a physical network supported by hardware plus multiple virtual networks. Operator's network evolves to the virtual and software direction, which could improve the flexibility of new business deployment, reduce the cost of network deployment and operating costs, and optimize network resource efficiency.
Besides, 5G has regular demand indicators: Firstly, meet 99.9% or higher reliability requirements, since the medical, production, security, and other fields are all have ultra-reliable requirements. Secondly, 100% coverage, the terminal can access the network at anytime and anywhere. Thirdly, reduce 90% of the network energy consumption. 5G will have a broad antenna array, which can reduce the transmit power and base station energy consumption, so we always call 5G is green communication. And 5G enhances the terminal battery life significantly, especially for some IoT equipment, the terminal battery life needs last to 10 years.
More importantly, 5G will provide the platform for cloud-based and artificial intelligence-based services. 5G networks will support the massive rollout of intelligent IoT nodes for a multitude of scenarios. 5G networks will provide a competitive platform to support the widespread adoption of critical communications services.
5G Application scenarios and challenges
Typical 5G scenarios involve future living, work, leisure, and transportation, for example, densely populated residential areas, offices, stadiums, outdoor gatherings, subways, high-speed rail, and wide-area coverage. These scenarios have features such as ultra-high traffic density, ultra-high connection number density, and ultra-high mobility, which may pose challenges to 5G systems. In these scenarios, consider 5G typical services such as augmented reality, virtual reality, ultra-high-definition video, cloud storage, connected cars, smart homes, and OTT messaging.
There are also examples of vertical industries supported by 5G include logistics, intelligent transportation, ultra-reliable communications, industrial applications, augmented reality, and agricultural applications.
