5G is fifth generation of wireless communication technology which support cellular data network, it have capacity of delivering more efficiently than 4G.
5G will elevate the mobile network to not only interconnect people, but also interconnect and control machines, objects, and devices. It will deliver new levels of performance and efficiency that will empower new user experiences and connect new industries. 5G will deliver multi-Gbps peak rates, ultra-low latency, massive capacity, and more uniform user experience.
The other generations of mobile networks before 5G
A: The other mobile network generations are 1G, 2G, 3G, and 4G.
- 1G delivered analog voice.
- 2G introduced digital voice (e.g., CDMA).
- 3G brought mobile data (e.g., CDMA2000).
- 4G LTE ushered in the era of mobile Internet.
The benefits of 5G
A: 5G is a new kind of network: a platform for innovations that will not only enhances today’s mobile broadband services, but will also expand mobile networks to support a vast diversity of devices and services and connect new industries with improved performance, efficiency, and cost. 5G will redefine a broad range of industries with connected services from retail to education, transportation to entertainment, and everything in between. We see 5G as technology as transformative as the automobile and electricity.
Other benefit of 5G
A: In general, 5G use cases can be broadly categorized into three main types of connected services:
- 5G will not only make our Smartphone better, but it will also usher in new immersive experiences, such as VR and AR, with faster, more uniform data rates, lower latency, and cost-per-bit.
- 5G will enable new services that can transform industries with ultra-reliable/available, low latency links—such as remote control of critical infrastructure, vehicles, and medical procedures.
- 5G will seamlessly connect a massive number of embedded sensors in virtually everything through the ability to scale down in data rates, power and mobility to provide extremely lean/low-cost solutions.
- A defining capability of 5G is also the design for forward compatibility—the ability to flexibly support future services that are unknown today.
How fast is 5G?
5G is expected to deliver peak data rates up to 20 Gbps and 5 Gbps in downlink peak data rate.
In addition to higher peak data rates, 5G will provide much more network capacity by expanding into new spectrum, such as millimeter wave (mmWave). 5G will also deliver much lower latency for a quicker immediate response, and an overall more uniform user experience so that the data rates stay consistently high even when users are moving around. Moreover, the new 5G NR (New Radio) mobile network will be backed up by Gigabit LTE coverage foundation, which will provide ubiquitous Gigabit-class connectivity.
How does 5G work?
A: Like 4G LTE, 5G is also OFDM-based and will operate based on the same mobile networking principles. However, the new 5G NR (New Radio) air interface will further enhance OFDM to deliver a much higher degree of flexibility and scalability. 5G will not only deliver faster, better mobile broadband services compared to 4G LTE, but it will also expand into new service areas
Who is working on 5G?
5Gis being driven by 3GPP, which is the standard body that also oversaw the development of 3G UMTS (including HSPA) and 4G LTE standards. 3GPP is a group of companies across the entire mobile ecosystem, all working on 5G. It ranges from infrastructure vendors and component/device manufacturers to mobile network operators and vertical service providers. Qualcomm Technologies is at the heart of the 3GPP, driving many essential inventions across all aspects of the 5G design, from the air interface to the service layer.
We expect the impact of 5G will be much greater than previous network generations. The development requirements of the new 5G network are expanding beyond the traditional mobile networking players to industries such as the automotive industry. That is why 3GPP is seeing a surge of new members that cut across a wide range of industries. It will take close collaboration among 3GPP members to make 5G a reality.
The difference between 4G and 5G
- 5G is a unified platform that is more capable than 4G
While 4G LTE focused on delivering much faster mobile broadband services than 3G, 5G is designed to be a unified, more capable platform that will not only elevate mobile broadband experiences, but also support new services such as mission-critical communications and the massive IoT. 5G will also natively support all spectrum type (licensed, shared, unlicensed) and bands (low, mid, high), a wide range of deployment models (from traditional macro-cells to hotspots), as well as new ways to interconnect (such as device-to-device and multi-hop mesh).
2. 5G uses spectrum better than 4G
5G will also get the most out of every bit of spectrum across a wide array of available spectrum regulatory paradigms and bands — from low bands below 1 GHz, to mid bands from 1 GHz to 6 GHz, to high bands known as millimeter-wave.
3. 5G is faster than 4G
5G will be significantly faster than 4G, delivering up to 20 Gigabits-per-second peak data rates and 100+ Megabits-per-second average data rates.
4. 5G has more capacity than 4G
5G will support a 100x increase in traffic capacity and network efficiency1.
5. 5G has lower latency than 4G
5G has significantly lower latency to deliver more instantaneous, real-time access: a 10x decrease in end-to-end latency down to 1ms1.
What is 5G Wi-Fi?
5G Wi-Fi isn’t a thing.
5G is the next-generation mobile technology defined by 3GPP (3rd Generation Partnership Project) – the standard body that also overlooked the development of 3G UMTS (including HSPA) and 4G LTE standards.
Wi-Fi is defined/standardized by IEEE and promoted/certified by the Wi-Fi Alliance, not 3GPP.
A 5G user will be able to seamlessly use 5G, 4G, and Wi-Fi since 5G will interwork both with 4G and Wi-Fi, allowing a user to simultaneously be connected to 5G New Radio (NR), LTE or Wi-Fi. Similar to Wi-Fi, 5G NR will also be designed for unlicensed spectrum without requiring access to licensed spectrum, which allows more entities to deploy 5G and enjoy the benefits of 5G technology.
