Key Takeaways
- 5G is three bands, not one technology: low-band travels far but runs close to 4G speed, mid-band is real upgrade and millimetre-wave is fastest but reaches less than a city beyond
- The famous "20 Gbps" figure is the standard's laboratory ceiling; the ITU's real-world benchmark is 100 Mbps down for a typical user.
- Health Canada's position: at the low levels people are exposed to, there are no health risks from 5G devices or towers and there is no established adverse health effects .
One Logo, Three Different Networks
"5G" is not a single technology — it is a family name for three very different kinds of radio spectrum. Low-band 5G (below 1 GHz) travels for kilometres and passes through walls, which makes it perfect for rural coverage — but its speeds are only a step above good 4G. Mid-band 5G (roughly 3.3–3.8 GHz) is the genuine upgrade: shorter range, far more capacity, and the speeds people picture when they hear "5G". Millimetre-wave 5G (above 24 GHz) is the sprinter — the fastest speeds and lowest lag, but signals that fade within hundreds of metres and are easily blocked by buildings, which is why it belongs in stadiums and dense downtown hotspots.
The Numbers Behind the Marketing
The standard behind 5G (the ITU's IMT-2020 requirements) sets a peak of 20 Gbps downlink — a laboratory ceiling for one device handed every resource under perfect conditions. The same document's honest benchmark, the "user experienced" rate, is 100 Mbps down / 50 Mbps up: what a typical user should get almost everywhere. Real Canadian 5G lives between those numbers, and which band your phone is on matters more than the logo beside your signal bars. Latency targets tell the same story — 4 milliseconds for ordinary broadband use, 1 millisecond for the ultra-reliable industrial applications (remote machinery, vehicles) that are still mostly ahead of us.
There's a second split most people never hear about. Early "5G" was non-standalone: 5G radios bolted onto a 4G core network. Standalone 5G connects to a new 5G core — and only standalone unlocks network slicing, carving one physical network into virtual networks tuned for video, vehicles or sensors. Most of what Canadians use today is still the bolted-on kind.
Where Canada Stands
Ottawa has auctioned the coverage bands first: 600 MHz in 2019, 3500 MHz in 2021 (200 MHz of mid-band), and 3800 MHz in 2023, which raised about $2.16 billion. The millimetre-wave auction — 26 and 38 GHz — is scheduled to open October 19, 2027. Translation: the blazing-fast flavour of 5G in American ads barely exists in Canada yet, and won't be licensed for years. Canadian 5G is a low-and-mid-band story.
And the Health Question
Health Canada's exposure guideline, Safety Code 6, covers every wireless frequency in use, and its limits are set far below the thresholds of all established adverse health effects — the only established effects of radiofrequency energy are nerve stimulation at very low frequencies and tissue heating at high exposure. Health Canada's stated conclusion: based on the available scientific evidence, there are no health risks from the low levels of radiofrequency energy people are exposed to from phones, towers and 5G devices. Every 5G device sold in Canada must meet those limits first.
The Twikup Take
5G is real — it's just three technologies wearing one logo, and Canada has so far bought the two slower, wider ones. Judge your network by the band, not the badge.
