How fast is 5G?
The newly defined 5G spectrum has three bands that offer 5G speed classes ranging from similar to 4G to groundbreaking changes.The first tier is the low band, with frequencies less than 1 GHz, usually between 600 and 900 MHz, which has the widest coverage in the 5G bands. However, low-level ice is only slightly faster than 4G.
Besides, low-band bands can give the vast majority of Vietnamese people some kind of faster and more reliable 5G coverage. In Vietnam, the low band has recently been the most focused and is guaranteed to provide speeds above 100 Mbit/s for coverage in industrial parks, export processing zones and large urban areas in 2022.
Next is the mid-band, also known as the C-band, which consists of frequencies from 1 to 6 GHz, providing speeds from 100 to 900 Mbps. The middle band has stable propagation, thanks to the wireless signal that can travel long distances. Service providers should have enough "land" to stream data at a fast rate.
Finally, there is the high band, also known as millimeter wave (mmWave). This band offers the ultra-fast connections we promise to bring to 5G. The bands operate from 24 to 40 GHz with the highest speed up to 3 Gbps. Download speeds in this band are 10 to 100 times faster than 4G.
High-band or mmWave transmission characteristics are quite limited because wireless signals can usually only be used at very short distances. Typically, this band works best within 305 meters of a 5G base station and in areas such as outdoors, near windows, or inside a building specially equipped with mmWave band cells.
Where and when can 5G be found?
All three 5G bands will continue to be deployed globally through 2023.
During deployment, consumers have the opportunity to better understand the
speed of 5G and the influencing factors, including: location and CSP.
The 5G toolkit offers a wide range of frequency bands with unique
characteristics. Low-band 5G spectrum is used for widespread coverage in
more rural areas while mmWave high-altitude bands can provide ultra-fast
speeds in urban environments. The mid-band will now provide efficient
scalability and provide near-universal 5G coverage at attractively fast
speeds.
The spread rate of mmWave varies from country to country. According to a report by Opensignal in September 2021, South Korea has the highest average 5G download speed of 406.5 Mbps. Taiwan (China), Norway, UAE and Sweden are in the top five.
The second factor that will determine 5G speeds is mobile operators or service providers (CSPs). Some vendors are making more aggressive 5G investments and deployments. Speed and coverage will also depend on CSP's strategy and spectrum holding. For example, some providers choose to deploy lower band for broad coverage, while others focus on providing ultra-high speeds in crowded urban environments.

The future and speed of 5G
Speed is just one factor in many of 5G's features. Along with advanced features such as ultra-low latency and support for millions of simultaneous connections on the same frequency, 5G technology promises to open new doors for innovation across industries. Extremely reliable connections will be the foundation for the new generation of autonomous vehicles. Ultra-low latency augmented reality (AR) interactions are helping retailers figure out how to give consumers an in-store experience right in their living room or enhance the mobile gaming and teleconferencing experience.For example, network split technology could become a platform for a separate 5G network, allowing businesses to buy or lease their own portion of a 5G network to support custom connectivity needs, while enhancing mobile security and a high level of data protection. As many as 95% of respondents to Jabil's 5G survey believe that 5G will provide both these new technologies and new business models to support innovations.
