5G networks are the next generation of mobile internet connectivity, offering faster speeds and more reliable connections on smartphones and other devices than ever before. Combining cutting-edge network technology and the latest high-spec devices, 5G should provide connections that are multitudes faster than previous mobile technologies, with average download speeds of around 1Gbps expected to be the norm across many (if not most) next-gen networks.
The networks are expected to supercharge Internet of Things technology, providing the infrastructure needed to handle massive amounts of data which will enable a smarter and more connected world. Literally, information from countless sensors could tell operators what is happening in your home, town, or even city in real-time.
5G networks have launched around the world with providers offering the connectivity technology across the US, UK and Australia, as well as a range of other countries around the globe. While rollout schedules have slowed due to the coronavirus outbreak, networks are still expanding, and carriers are continuing with their plans to extend current setups and launch nodes in new areas and cities. Many of these networks are working alongside existing 3G and 4G technology to provide speedier connections that stay online regardless of where you are. You may already be able to access 5G where you live, and below we’re going to talk you through exactly what 5G is and more.
What is 5G?
5G is the 5th generation mobile network. It’s a brand new global wireless standard after 1G, 2G, 3G, and 4G networks. 5G enables a new kind of network that’s designed to connect virtually everyone and everything together including machines, objects, and devices.
5G wireless technology is supposed to deliver higher multi-Gbps peak data speeds, ultra low latency, more reliability, massive network capacity, increased availability, and a more uniform user experience to more users. Higher performance and improved efficiency empower new user experiences and connects new industries.
What are the differences between the previous generations of mobile networks and 5G?
The previous generations of mobile networks are 1G, 2G, 3G, and 4G.
- First generation – 1G – 1980s: 1G delivered analog voice.
- Second generation – 2G – Early 1990s: 2G introduced digital voice (e.g. CDMA- Code Division Multiple Access).
- Third generation – 3G – Early 2000s: 3G brought mobile data (e.g. CDMA2000).
- Fourth generation – 4G LTE – 2010s: 4G LTE ushered in the era of mobile broadband.
1G, 2G, 3G, and 4G all led to 5G, which is designed to provide more connectivity than was ever available before.
5G is a unified, more capable air interface. It’s been designed with an extended capacity to enable next-generation user experiences, empower new deployment models and deliver new services.
With high speeds, superior reliability and negligible latency, 5G will expand the mobile ecosystem into new realms. 5G will impact every industry, making safer transportation, remote healthcare, precision agriculture, digitized logistics and more a reality.
How does 5G work?
Like 4G LTE, 5G is also OFDM-based (Orthogonal frequency-division multiplexing) and can 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, like mission-critical communications and connecting the massive IoT. This can be enabled by many new 5G NR air interface design techniques, like a new self-contained TDD subframe design.
How fast is 5G?
5G is designed to deliver peak data rates up to 20 Gbps based on IMT-2020 requirements. Qualcomm Technologies’ flagship 5G solutions, the Qualcomm® SnapdragonTM X55 and Snapdragon X60 Modem-RF Systems, are engineered to achieve up to 7.5 Gbps in downlink peak data rates.
But 5G is about more than just how fast it is. In addition to higher peak data rates, 5G is meant to provide much more network capacity by expanding into new spectrum, like mmWave.
5G can also deliver much lower latency for a more instantaneous response and can provide an overall more uniform user experience so that the data rates stay consistently high even when users are on the move. And the new 5G NR mobile network is backed by a Gigabit LTE coverage foundation, which can provide ubiquitous Gigabit-class connectivity.
Is 5G available now?
Yes, 5G is already here today, and global operators started launching new 5G networks in early 2019. In 2020, many countries expect nationwide 5G mobile networks. Also, all major Android phone manufacturers are commercializing 5G phones. And soon, even more people will be able to access 5G.
5G has been deployed in over 35 countries and counting. We are seeing much faster rollout and adoption compared with 4G. Consumers are very excited about the high speeds and low latencies. But 5G goes beyond these benefits by also providing the potential for mission-critical services, enhanced mobile broadband and massive IoT. While it’s difficult to predict when everyone will have access to 5G, we are seeing great momentum of 5G launches in its first year and we expect more countries to launch their 5G networks in 2020 and beyond.
As of June 2020, 5G was available in:
- Czech Republic
- Hong Kong
- New Zealand
- Puerto Rico
- Saudi Arabia
- South Africa
- South Korea
- Trinidad and Tobago
- United Arab Emirates
- United Kingdom
- United States of America
- Virgin Islands, U.S.
This covers the key details about 5G networks – what they are, how fast they are, and where they are available now. 5G is the next evolution in mobile connectivity, offering faster speeds, lower latency, and the ability to connect more devices than ever before. As 5G continues rolling out across more countries, even more people will be able to take advantage of the improvements this new technology offers.
