The 6G Network: Your Questions Answered
Updated: March 11, 2022
From the 5G to 6G Network
As our demand for IoT devices and technological advances continues, a faster wireless cellular technology is needed to back it. 5G may have just started, but that doesn’t mean we shouldn’t prepare for 6G. Looking into the future, the need for 6G will happen. Like what’s happening with 4G now, 5G will also reach its maximum potential, limiting future technology advancements.
Because the 6th generation is just new to us, many questions surround the new wireless network.
What is 6G?
Like 1G and 5G, 6G technology is the 6th generation of wireless cellular networks. Although next in line after 5G, moving from 5G to 6G will take considerable time. What’s considered 6G now may also be called 5G Advanced or 5.5G later on, similar to other generations such as 3.95G or 4G LTE. Time will tell whether this is true or not, but let’s consider it as 6G for this article’s sake.
How Will the 6G Network Work?
It’s impossible to say how the 6G network will work today.
As of now, we know 6G’s network will use higher frequencies than 5G, providing higher capacity while decreasing latency issues even further.
6G is estimated to use terahertz (THz) frequencies – much higher than 5G’s gigahertz (GHz). One research issue involving the interface between the terahertz spectrum and hard fibre optical transmission lines has arisen. Hardwiring is needed to reach longer distances using 6G, but it’s not quite possible to connect THz to these lines yet. Along with these transmission lines, “spatial multiplexing” (when individual data signals are beamed in streams) is also required to get 6G’s maximum bandwidth efficiency. (Source: Network World)
How Fast is the 6G Network?
To put things into perspective, 4G’s median download speed in Canada is 55.5 Mbps. But today, Canada sees a median 5G download speed of 170 Mbps, making it 205% faster than 4G in Canada!

6G is sure to have an extraordinary gain in speed, expected at one terabyte per second (1 TBps) or 8000000 megabits per second (8000000 Mbps), according to Dr. Shirvanimoghaddam. (Source: ABC News)
That’s a 4705782% increase compared to Canada’s current 5G speed of 170 Mbps!
Dialling back the excitement, it’s only speculation at this point. There’s still a vast amount of research and testing that’s needed. Also, other scientists and sources of information claim different expectations. For example, Wikipedia states that 6G will reach 95000 megabits per second (95000 Mbps) – a much lower expectation than 1 TBps.
Will the 6G Network be Harmful?
Many myths and conspiracy theories have revolved around 5G in the past few years, stating that 5G is dangerous and could harm people. There’s also a dangerous conspiracy saying that 5G started the COVID-19 pandemic. The truth, however, is far from this.
However, some people will still ask, “If 6G uses higher frequencies than 5G, isn’t that dangerous?”
However, 6G’s frequencies were opened up by the FCC and estimated to be between 95 GHz to 3 THz (Source: FCC) – that’s 3 to 1000 times more potent than 5G’s frequencies.
If that’s the case, are they still safe?
Looking back at the chart, yes, they are still safe because the frequencies are non-ionizing.
That’s a lot of room for frequency improvement before it becomes hazardous.

Who’s Inventing the 6G Network?
Even though 5G isn’t entirely out yet, research has already started on 6G technology. So far, the prominent companies and organizations to this date include:
- University of Oulu (Finland)
- Virginia Tech (USA)
- Ministry of Science and Technology (China)
Although this isn’t a complete list, it’s important to note that 6G will not be invented by just one person or one company. The race to 6G is international and will involve numerous people, organizations, and countries.
When Will 6G Come Out?
6G is expected to launch to the public in 2030. Various scientists and researchers say it may take until 2035 to reach 6G’s maximum potential. (Source: CNN)
When Will the 6G Network Arrive in Canada?
It’s tough to say when 6G will arrive in Canada.
Looking back at previous cellular generations, it took most of the G’s some time to reach the Canadian market. For example, 1G launched in Tokyo in 1979, and Canada didn’t access the network until the mid-1980s. 4G established itself near the end of 2009, and Canada didn’t get its first 4G network until mid-2011. 5G deployments are also taking time. Introduced to the South Koreans in March 2019, Canada didn’t get access to 5G until almost a year later -January 2020. (Source: Engadget)
Looking back, 6G won’t be readily available to the Canadian public until 2031 or 2032, but that’s only a guess.
What Will 6G Technology Be Like?
Although we haven’t even seen the full potential of 5G, 6G is still under question. 6G has been nicknamed “wireless cognition” by researchers, meaning that robots and artificial intelligence could have the same intelligence and function as humans. The only difference is that the intellect is sent through 6G airwaves.
The University of Oulu in Finland suggests this is what 6G will look like in our daily lives – similar to an optimistic sci-fi film full of new technologies and amusing ways to use them.
6G could also significantly increase cell phone capabilities. One example talks about how 6G phones could test the air around you for toxic chemicals or even test if your food is safe to eat. Users could also use 6G phones to see through walls by building up maps of local surroundings. (Source: CNN)
However, 6G research has only begun, so it’s impossible to determine whether or not this will happen.
6G: Sci-Fi For Real
We haven’t seen the full benefits of 5G just yet, but that doesn’t mean we shouldn’t be asking questions about the future generation of wireless cellular technology. Just like 5G, 6G will be a revolution itself. With even lower latency than 5G and potential speeds of 1 TBps, 6G will open the doors to new technologies. 6G could also create possible ways of living we’ve seen in the past – through science fiction films.
For now, all we can do is wait and enjoy the ongoing introduction of innovations and benefits coming from 5G – unless you’re a part of 6G development.
If that’s the case, you’ve got a lot of meaningful work ahead.
