Question 1

What do 5G bands actually mean, and why is 5G sometimes slower than 4G?

Accepted Answer

Because "5G" describes a **family of radio technologies across very different frequencies**, and the band you happen to be on matters far more than the generation label on your phone.

**The three bands, which behave nothing alike:**

**Low band**, below 1GHz. Travels many kilometres, penetrates buildings well, and offers speeds broadly comparable to good 4G. Most wide-area 5G coverage is this, which is why the icon appears without the speed.

**Mid band**, roughly 1–6GHz. The genuine sweet spot — several times 4G's throughput with workable coverage. This is what most people mean by 5G working properly.

**High band**, or millimetre wave, above 24GHz. Enormous capacity and **almost no range** — hundreds of metres, blocked by walls, foliage and rain, and in some cases by your own hand. Deployed in stadiums and dense city centres, not across countries.

**Why your 5G can be slower than 4G:**

**You are on low band**, which is not faster by design.

**Dynamic spectrum sharing**, where the operator runs 4G and 5G in the same spectrum simultaneously so 5G appears everywhere. It does not add capacity, and carries overhead — **5G that is slower than the 4G it replaced is usually this.**

**The icon is lying slightly.** Non-standalone 5G uses a 4G core and a 4G control channel, with 5G added for data. Some operators display 5G on the basis of the cell's capability rather than what you are actually using.

**Congestion**, which no radio technology fixes.

**Falling back** at the edge of coverage, where handover churns.

**The backhaul**, since a mast is only as fast as its connection to the network.

**What 5G genuinely improved** beyond speed: **latency**, meaningfully lower on standalone networks; **device density**, supporting far more connections per cell; and **network slicing**, letting operators partition capacity for specific uses.

**Practically:** if 5G is consistently worse, locking the phone to 4G in a given place is a reasonable thing to do.

Question 2

What is the difference between 2.4 GHz and 5 GHz WiFi?

Accepted Answer

The two bands trade range against capacity, and neither is better in general. The lower frequency travels further and passes through walls more effectively. The higher frequency carries substantially

Question 3

What is fixed wireless access, and is it as good as a cable?

Accepted Answer

Fixed wireless access (FWA) delivers broadband to a building over a radio link rather than a wire — typically from a mobile network's 4G or 5G masts to a receiver in your home. Why it exists. Digging

Question 4

Why is my WiFi slow even though my internet plan is fast?

Accepted Answer

The speed you buy is delivered to your router. What reaches your laptop is whatever survives the wireless link, and those two numbers are frequently very different. Testing over a cable is the

Question 5

How does a mobile network hand over between masts?

Accepted Answer

Continuously and invisibly — your phone is constantly measuring nearby cells and the network moves your connection between them, ideally without you noticing. What a cell actually is. A mast site is

Question 6

What is radio spectrum, and why is it auctioned?

Accepted Answer

Spectrum is the range of radio frequencies usable for wireless communication — and it is auctioned because it is a genuinely finite shared resource where two users of the same frequency in the same

Question 7

Why does satellite internet have such different latency?

Accepted Answer

Because latency over satellite is dominated by orbital altitude, and the difference between orbits is a factor of forty. Geostationary orbit (GEO), at roughly 35,786 km. A satellite there orbits at
