The deployment and testing of 5G mobile networks are underway in selected cities and countries, with official global deployment expected in 2020. To understand what 5G is all about, readers are invited to explore the comprehensive guide on 5G, the 5th generation mobile network, provided by Mytour.vn below.
Exploring the Wonders of 5G, the 5th Generation Mobile Network
What is 5G?
5G is the 5th generation mobile network, delivering faster speeds and reliable connections on mobile devices and other gadgets.
By combining advanced network technology and the latest research, 5G will deliver significantly faster connections than current ones, with an average download speed of around 1GB/s, promising to become the standard network generation soon.
Additionally, 5G holds the promise of enhancing Internet of Things technology, providing the necessary infrastructure to handle massive amounts of data, enabling smartphones and other devices to connect more seamlessly.
With its anticipated global launch in 2020, alongside current 3G and 4G technologies, 5G is set to provide faster connections, allowing users to be online anytime, anywhere.
How does 5G work?
Unlike LTE, 5G operates on three different frequency bands. While this may not seem crucial, it will significantly impact your daily usage.
- Low-band spectrum, also known as sub-spectrum 1GHz, is primarily the spectrum range used by U.S. networks as a replacement for LTE and quickly depletes. Although low-band spectrum provides extensive coverage and penetration, its major drawback is that the highest data speed reaches only about 100Mb/s.
When discussing low-band spectrum, one cannot overlook T-Mobile, the third-largest U.S. telecommunications network, utilizing the 600MHz frequency spectrum acquired in the FCC auction of 2017 for 5G broadcasting.
- Mid-band spectrum: providing faster coverage and lower latency compared to low-band spectrum, with a maximum data speed of up to 1Gb/s.
Sprint focuses on unused mid-band spectrum in the U.S., employing Massive MIMO technology to enhance penetration and coverage in the mid-range spectrum. Utilizing multiple transmit and receive antennas, this approach is crucial, especially as the user base continues to grow.
Additionally, Sprint employs Beamforming to improve 5G service on the mid-band spectrum. Beamforming sends a concentrated signal to each user within a cell, and systems using it monitor each user to ensure consistent signal usage.
- High-band spectrum, also known as mmWave. High-band spectrum can provide maximum speeds of up to 10Gb/s with very low latency. However, the limitation of high-band spectrum lies in low coverage and poor penetration of high-rise buildings.
Both AT&T and Verizon are deploying high-band spectrum. The 5G coverage areas for both networks will carry LTE as they build nationwide networks. Due to the demands of high-frequency spectrum for penetration, coverage areas, and high speed, they will rely on small cells.
Small cells are low-power base stations covering small geographic areas. With small cells, networks utilizing mmWave for 5G can enhance overall coverage. Combined with Beamforming, small cells can provide extremely fast coverage with low latency.
Using 5G in what fields?
- Enhancing bandwidth: Transitioning to 5G will undoubtedly change how we interact with technology daily. Moreover, 5G is crucial for utilizing wide mobile bandwidth.
In many large urban areas, LTE capacity is running out. 5G supplements a significant spectrum in previously unused bands for commercial wide bandwidth traffic.
- Infrastructure and public safety: 5G offers solutions for more efficient operations in cities and regions. Utility companies can easily monitor remote usage, sensors can alert public works departments to flood or streetlight outages, and urban areas can swiftly install surveillance cameras without high costs.
- Remote device control: Due to the significantly low latency of 5G, remote control of devices, heavy machinery, becomes easier. While the primary purpose is risk reduction in hazardous environments, it also allows skilled technicians to control machinery from anywhere in the world.
- Healthcare: The Ultra-reliable low latency communications (URLLC) component of 5G could revolutionize healthcare services. With URLLC reducing 5G latency, even more than what you'd experience with mobile broadband, we can expect improvements in remote treatment, remote recovery, and physical therapy through AR, precise surgeries, and even remote surgeries in the coming years.
- IoT: One of the most intriguing and crucial aspects of 5G is its impact on the Internet of Things. While current sensors can communicate with each other, they tend to demand many resources and quickly deplete LTE data capacity.
With the low latency and high speed of 5G, IoT will be powered by communication between sensors and smart devices (referred to as mMTC here). Compared to current smart devices in the market, mMTC devices will require fewer resources, as a large number of these devices can connect to a single station.
