What should everyone know about 5G?
The term "5G" has gained popularity in the consumer electronics sector as it promises extraordinary high-speed connectivity, low latency and wide bandwidth that can be exploited. But 5G is more than just a buzzword, it has the potential to fundamentally change connectivity around the world.
realme has been at the forefront of democratizing 5G technology for the masses. We have introduced 23 5G smartphones that are 5G ready because we truly believe in bringing high-speed connectivity to the masses and devices that embody our Dare To Leap core principle.
All realme 5G smartphones are 5G NSA compatible and 85% are SA compatible and the rest will soon receive software updates to be fully compatible with the SA architecture.
What is 5G?
The 1G network only supported analog voice for receiving calls. The second generation of networks, or 2G, brought additional capacity as well as the ability to call and send SMS using digital voice. The 3G network provided Internet connectivity, while the 4G network, also known as LTE, introduced high-speed mobile broadband and helped spark the social networking boom.
The fifth generation of mobile network technology, or 5G, promises minimal latency, extremely high network capacity and fast connections. It offers unified connectivity and can support both smartphones and AIoT devices on the same network.
Today, this 5G can work on almost any frequency from 600 MHz to 40 GHz, including the current ones that we already use for mobile communication.
The 5G network is currently available in three bands, low band, mid band and high millimeter wave.
High-band millimeter wave offers ultra-fast connections of up to 20 Gbps, but with minimal coverage, while low-band 5G operates at the lower end of the 5G spectrum and can offer faster connection speeds than 4G with a high coverage area. Midband offers a faster connection but with a limited coverage area.
5G vs 4G
The 4G network was designed for smartphones to offer high-speed mobile broadband, but is limited in capacity.
5G, on the other hand, offers much better network capacity that can handle up to 1 million devices per square kilometer.
5G is about 100 times faster than the 4G network and can offer lower latency speeds of up to 1ms than 4G, which peaked at 10ms latency.
The 5G network uses network sharding, which allows it to function as many separate networks. A slice can act as an independent network for a specific purpose that uses network resources without wasting resources on things it doesn't need.
5G NR, SA and NSA
5G NR stands for 5th Generation New Radio. 5G NR represents how 5G NR devices and 5G NR network infrastructure will communicate via radio waves.
5G NR will be implemented together with 4G LTE using the existing 4G infrastructure in NSA (Non-Standalone) mode.
The network infrastructure for 5G SA (standalone) will require the base station, radio antenna and end devices (smartphones) to be built using the 5G architecture. 5G SA will not use LTE and will operate independently of 5G standards.
The future of 5G
Think of a world in which not only people are connected, but all things: cars with the roads they travel on; doctors to their patients' personal medical devices; augmented reality that helps people shop, learn and discover wherever they are. This requires a massive increase in the level of connectivity.
According to the World Economic Forum, 5.1 billion people connect to the Internet using mobile devices, and more than half of those connections come from smartphones.
With the fast speeds, good reliability and low latency of 5G, the mobile ecosystem will expand into new domains. 5G will impact every industry and enable innovations such as safer mobility, remote healthcare, precision agriculture, digitized logistics, smart home and many more.
Everyone and everything will be consistently and securely connected to the cloud thanks to 5G. When everything is always connected, we have access to the almost unlimited processing and storage capacity of the cloud, which creates remarkable efficiency and encourages creativity.
