5G Wireless Technology
- FAQs | 5G Wireless Technology
Help me understand the basics of cellular technology. How does my phone send and receive information; and what exactly is the wireless spectrum that I hear so much about?
This means that cellphones essentially function the same way as any wireless device, ranging from garage door openers to baby monitors or cordless phones. A key difference is in the type of information that can be transmitted, the range in which individual wireless devices can communicate, and the speed at which these devices transmit information.
What does a cellular network do?
Service providers, such as Verizon and AT&T, make use of their cellular networks to provide wireless service to their customers almost anywhere in the country. Cellphones have more powerful computer chips and bigger antennas than most household wireless devices, allowing them to process different data streams such as voice, photos and video. To communicate information over long distances, cell towers (or base stations) collect and send data from cell phones to the Internet through a cellular core network. Cellular data moves to the core network on cables called the backhaul. The core network then delivers data from hundreds of cell towers to the appropriate location and user.
What exactly is 5G? How is 5G different than previous generations of cellular technology? Why is it such a big deal?
Are there any major differences between 5G and previous cellular generations like 2G, 3G and 4G?
How do separate wireless technologies avoid interfering with one another?
For instance, garage door openers operate at around 40 megahertz, while the 700 megahertz bands are used in U.S. to provide a large part of the current cellular service. Frequently Asked Questions The range of all available frequencies is called the wireless spectrum. Spectrum is a finite resource governed and administered by the National Telecommunication and Information Administration (NTIA) and the Federal Communications Commission (FCC).
Why is a spectrum shortage a concern? Would 5G help?
This is particularly concerning for wireless systems that require constant connectivity such as navigation systems, drones or emergency communication systems. Due to the ever-evolving nature of technology and a possible spectrum shortage, the wireless industry has continually evolved the capabilities of wireless devices to more efficiently send and receive information. This is where 5G comes into play.
What is “spectrum agile” and how is it used?
These smaller cell sites and smaller antennas will augment existing large cell towers and help alleviate cellular congestion in crowded areas like office buildings, sports stadiums or during special events where large groups of people gather and use many simultaneously connected devices.
Years from now when 5G is fully deployed, will mobile devices and other technologies become 5G-enabled?
What are some of the advantages of 5G technology and how will it be used?
When fully deployed, 5G could rival or surpass cable speeds. It will also reduce latency; the annoying lag or buffering that occurs when your phone, tablet or other electronic device waits to start receiving incoming data.
What are some of the challenges of 5G technology?
This is changing quickly; however, as major cellular providers and technology companies embrace and invest in 5G infrastructure. Security is also a significant challenge for 5G technology. With an expected increase in devices utilizing 5G communication, more attention and research needs to examine ways to secure the flow of data to and from 5G-enabled devices. This is an area of research at Idaho National Laboratory.
What is the difference between 5G and WiFi?
Are there health effects associated with 5G technology? Should people worry about 5G?
Is 5G available now? When will it be deployed nationwide?
However, every major cellphone provider is investing heavily in the infrastructure to support 5G deployment. Nationwide availability is still several years away and will be phased in incrementally.
How much will 5G cost to implement?
How is Idaho National Laboratory involved in 5G?
We own, operate and manage a best-in-class external Wireless Test Bed that includes 2G, 3G and 4G technology, including fixed and mobile towers, relay stations, network and switch gear.
Initial security testing of 5G devices will begin in June 2020, and the initial, non-standalone, 5G external range capability will be operational in November 2020. INL plans to add new 5G technology as it becomes available.
What has INL done to advance 5G technology?
One of these technologies is under consideration for incorporation in national 5G standards, and another will help monitor and protect 5G frequency usage.
In 2019, INL launched a Wireless Security Institute to lead national research efforts to develop technology solutions to enhance 5G security. The first of many workshops and conversations to address wireless security standards was hosted by INL in Salt Lake City on Feb. 27, 2020.
