Almost every 4G-versus-5G comparison is assembled from marketing material, and marketing material in this field quotes ceiling figures obtained under laboratory conditions as though they described a Tuesday afternoon on a train.
The underlying documents are public and specific. The International Telecommunication Union publishes the minimum technical performance requirements a radio technology must meet before it can be called 4G or 5G at all, and every figure in the next section comes from those reports directly — ITU-R M.2410-0 for IMT-2020, which is 5G, and ITU-R M.2134 for IMT-Advanced, which is 4G.
We are Geonode and we sell proxies, including mobile ones, so the honest disclaimer belongs here: the generation of radio a device used is invisible to the website it connects to. A site sees an IP address and the network it belongs to. It cannot see whether the packets crossed a 4G or a 5G air interface, because that information does not survive past the carrier's own network. Two sections below explain why that makes "5G proxies" much closer to a label than a product tier, which is a strange thing for a proxy company to write and is nevertheless true.
What genuinely changed between the two generations is less about the top speed than the marketing suggests. The peak requirement went up twentyfold, but the requirement that reshapes what applications are possible is latency — and the one that reshapes what networks are for is connection density, which went up by a factor that does not fit on an advertisement.
One caveat applies to everything below. These are minimum requirements for a technology to qualify, evaluated under defined test conditions. They are not predictions about your phone, and the gap between the two is enormous.
What the Standards Actually Require
Here is the comparison from the source documents, side by side.
| Metric | 4G (IMT-Advanced) | 5G (IMT-2020) |
|---|
| Peak data rate, downlink | 1 Gbit/s (low mobility) | 20 Gbit/s |
| Peak data rate, uplink | — | 10 Gbit/s |
| Peak at high mobility | 100 Mbit/s (to 250 km/h) | — |
| User experienced rate, downlink | — | 100 Mbit/s (dense urban) |
| User experienced rate, uplink | — | 50 Mbit/s (dense urban) |
| User plane latency | < 10 ms | 4 ms (broadband), 1 ms (ultra-reliable) |
| Control plane latency | < 100 ms | 20 ms |
| Connection density | — | 1,000,000 devices/km² |
| Mobility supported | to 250 km/h | to 500 km/h |
| Reliability | — | 99.999% for a 32-byte packet within 1 ms |
Reading This Properly
The peak rate is a ceiling, not a promise. M.2410-0 defines peak data rate as the maximum achievable "under ideal conditions", with maximum bandwidth aggregated across all supported bands and a single user having the entire cell to themselves. It exists so that technologies can be compared on a defined basis. Nobody has ever experienced it on a phone and the specification does not suggest anyone will.
The user experienced data rate is the more honest figure, and it is a 5G-era addition. At 100 Mbit/s downlink and 50 Mbit/s uplink in a dense urban test environment, it describes what the specification expects a typical user near the edge of good service to actually get. That is two hundred times below the peak headline, and it is the number worth remembering.
The latency figures are narrower than they look. M.2410-0 defines user plane latency as the contribution of the radio network to one-way delivery, measured with a single user, unloaded conditions, and a zero-byte payload plus IP header. It is a measurement of the air interface only. The internet beyond the tower — backhaul, routing, the server's own response time — is not included and typically dwarfs it.
Connection density is the quiet revolution. One million devices per square kilometre is not about phones. It is about sensors, meters, trackers and industrial equipment, and it is the requirement that made 5G a different kind of network rather than a faster version of the previous one.
Reliability got a formal definition. 99.999% success probability for delivering a 32-byte packet within 1 millisecond, at the coverage edge, in an urban macro test environment. 4G's requirements simply did not address this, because the applications that need it did not exist yet.
Why Your Phone Never Sees Those Numbers
The gap between specification and experience is not a scandal. It is what the specification means. Five reasons, roughly in order of how much they cost you.
You are sharing the cell. Peak figures assume one user. In reality a tower's capacity is divided among everyone attached to it, which is why speeds collapse at a railway station at half past five and recover at three in the morning. This single factor accounts for most of the variation people notice.
Bandwidth is what you actually have, not what exists. The peak figure assumes aggregation across every supported band at maximum width. Your carrier owns a particular allocation in your area, your phone supports a particular set of bands, and the intersection is usually modest.
Distance and obstruction degrade everything. Signal strength falls with distance and with anything in the way. The higher the frequency, the worse this gets — which is the entire story of the next section.
The bottleneck often is not the radio. A 1 ms air interface attached to a server that takes 200 ms to think about your request produces a 200-plus millisecond experience. Improving the fastest link in a chain changes very little.
Carriers manage traffic. Prioritisation, deprioritisation after a data threshold, and video quality caps are all normal parts of a commercial mobile network and none of them appear in a technical specification.
What Actually Improved
Despite all of that, the practical change is real. The useful way to describe it is not "5G is twenty times faster" but:
More capacity in the same place. A 5G cell serves more simultaneous users at usable speeds. The benefit shows up as not degrading in a crowd, which is less exciting and more valuable than a peak number.
Better uplink. 4G networks were built on the assumption that people download far more than they upload. That assumption aged badly, and 5G's uplink provisions matter for anyone sending video, backing up, or running anything that pushes data outward — including, incidentally, a mobile proxy.
Lower and more consistent latency. Not the 1 ms headline, but a genuine and noticeable improvement, and more importantly a more stable one. Consistency matters more than the median for anything interactive.
The Three Flavours of 5G
This is the part that explains why two people can both have "5G" and completely different experiences, and it is rarely made clear.
5G runs across a wide range of frequencies, and the physics of radio means frequency trades directly against range. Three bands are in common use.
Low-band, below 1 GHz
Travels a long way, penetrates buildings well, and covers large areas from few towers. Speeds are modest — frequently comparable to good 4G, sometimes slower.
This is what most rural and much suburban 5G coverage actually is. Your phone displays a 5G indicator and the experience is essentially unchanged. That is not a fault; it is a deliberate trade of speed for coverage, and it is the reason coverage maps turned green so quickly.
Mid-band, roughly 1–6 GHz
The useful compromise, and the band most of the industry has settled on. Meaningfully faster than 4G, with range and building penetration that remain practical. Sometimes marketed under its own name to distinguish it from the low-band experience.
If you have noticed 5G being genuinely better, this is almost certainly what you were connected to.
Millimetre wave, roughly 24 GHz and above
Enormous capacity, extraordinary speeds — and range measured in hundreds of metres, blocked by walls, foliage, rain, and in some conditions a hand in the wrong place.
This is where the spectacular demonstration figures come from. It is deployed in dense, specific locations: stadiums, airports, city centres, conference venues. Coverage is a set of small islands rather than a blanket, and outside those islands your device falls back to something else.
Why This Matters More Than the Generation Label
"5G" on your status bar tells you almost nothing about what you will get. Low-band 5G may be slower than a good mid-band 4G connection. Millimetre wave may be twenty times faster than either, for as long as you stand still and nothing comes between you and the transmitter.
Anyone comparing 4G and 5G experiences without knowing which band was involved is comparing two things that happen to share a name.
There is a fourth distinction worth knowing about: standalone versus non-standalone. Early 5G deployments used 5G radio attached to a 4G core network, which meant the radio was new and much of the latency and flexibility benefit was not available. Standalone 5G runs on a 5G core throughout, and it is where the latency and network-slicing capabilities actually live. Two networks can both be "5G" and differ substantially on this.
Latency: The Change That Matters More Than Speed
If you take one technical point from this article, take this one.
Bandwidth determines how much data you can move. Latency determines how long you wait before anything happens. For a great many applications, the second is the constraint — and it is the one that improved most meaningfully.
The Numbers, Carefully
4G's requirement was under 10 ms user plane latency in unloaded conditions. 5G's is 4 ms for enhanced mobile broadband and 1 ms for ultra-reliable low-latency communication.
Both are radio-network contributions only, measured with one user and a minimal packet. Neither is an end-to-end figure and neither should be quoted as one.
Why It Changes What Is Possible
Below roughly 20 ms of total round trip, interaction starts to feel immediate rather than remote. Above 100 ms, it feels like operating something at a distance. The applications that sit between those thresholds are the ones 5G's latency profile unlocks:
Remote control of physical things, where a delayed response is a safety property rather than an annoyance. Industrial automation with coordinated machinery. Vehicle communication. Cloud-rendered interactive applications, where every input crosses the network twice.
None of these were impossible on 4G. All of them were marginal, and marginal is not deployable.
The Honest Limit
The air interface is one segment of a path. A request from your phone crosses the radio link, the carrier's backhaul, the public internet, and arrives at a server that takes its own time to respond — then all of it happens again in reverse.
Cutting the radio contribution from 10 ms to 4 ms improves a 90 ms round trip to about 78 ms. Real, worthwhile, and not the thousandfold transformation that "1 millisecond" implies to a casual reader. The 1 ms figure describes a specific ultra-reliable mode in a specific test environment, not general phone use.
Where it genuinely transforms things is inside controlled deployments — a factory with local infrastructure, where the whole path is short and the radio really is the dominant term.
Coverage, Battery and the Practical Trade-offs
Every gain has a corresponding cost, and these rarely appear alongside the speed figures.
Coverage is uneven and will stay that way. 4G had a decade to reach near-universal coverage in developed markets. 5G is still filling in, and the higher bands are physically incapable of matching 4G's coverage economics — the towers would have to be impossibly dense. Rural 5G will be low-band 5G, which is 5G in name and roughly 4G in experience.
Battery consumption is generally higher, particularly on higher bands and while a device is switching between generations. It has improved with each hardware generation and it has not disappeared. Anything running continuously on battery is affected.
Fallback is constant and invisible. Devices move between 5G and 4G continuously as you walk around. Each transition costs a moment of instability. On the edge of coverage a device can oscillate, which is worse for both battery and consistency than simply staying on 4G — which is why manually pinning a device to 4G sometimes produces a better experience than leaving it to choose.
Indoor performance depends on the band. Low-band penetrates walls; millimetre wave essentially does not. A building can have excellent outdoor 5G and nothing usable inside.
Device support varies by band, not by generation. A phone advertised as 5G may not support the specific bands your carrier uses locally. This is worth checking against your carrier's actual allocation rather than the box.
The Summary Nobody Puts on a Poster
5G is better in dense areas with mid-band or millimetre wave coverage, roughly equivalent in areas with low-band coverage, and absent where deployment has not reached. Which of those you experience depends on where you are standing, and the label on your phone does not distinguish between them.
What This Means for Mobile Proxies
Our territory, so weigh it accordingly — and this section contains the point we would most like people to take away, because it argues against a common upsell.
What a Mobile Proxy Is
A mobile proxy routes requests through a device connected to a cellular carrier, so the destination sees an address from that carrier's mobile network rather than from a data centre or a home broadband line.
The reason this is treated leniently by many sites has nothing to do with radio technology. It is that mobile addresses are shared, heavily, by design. Carriers place large numbers of subscribers behind carrier-grade network address translation, so a single public address may represent hundreds or thousands of real customers at once. Blocking it blocks a great many genuine people, and sites that care about their users are correspondingly reluctant.
The address also rotates naturally. Subscribers move between towers and reconnect, and addresses get reassigned as a normal consequence of how the network operates rather than as a feature someone built.
What Changes With 5G
Uplink improves, and for a proxy this is the relevant direction more often than for ordinary phone use. Requests go out and responses come back; a device relaying traffic for someone else is doing more sending than a typical handset.
Latency improves slightly, which is genuinely nice and is a small term in a total that is dominated by the route to the destination server.
Capacity per cell improves, which matters if many proxied sessions share one location.
What Does Not Change
The carrier network the address belongs to. The address-sharing behaviour that makes mobile addresses valuable. How the destination site classifies the address. Whether your request pattern looks like a person.
All of which leads to the next section.
Why 5G Proxy Is Mostly a Label
A product tier we would rather explain than sell.
The website cannot tell. When a request reaches a server, the server sees an IP address, and it can look up which organisation that address block is registered to. It sees the carrier. It does not see the radio technology, because the radio technology is a property of one hop inside the carrier's network and does not survive into the packet that arrives.
There is no header, no field, no fingerprint that says "this device was on 5G". A 4G device and a 5G device on the same carrier draw addresses from the same pools and are, from outside, indistinguishable in the way that matters.
What actually determines how mobile addresses are treated is the carrier network they belong to, how heavily that address is shared, whether that particular address has been abused recently, and — far more than any of it — whether your traffic behaves like a person's.
So what does "5G" get you? Marginally better throughput and latency on the connection itself. If you are moving large volumes through a mobile proxy, that is a real benefit and worth something. It does not improve your chances of getting a page, because nothing about the page's decision depends on it.
Where the premium is sometimes justified anyway. Newer infrastructure often means better-maintained equipment and less contended capacity. But you are buying throughput, not acceptance, and the two get conflated in marketing constantly.
The question worth asking any provider, including us, is not what generation the radio is. It is: which carriers, how many addresses, how are they shared, how often do they rotate, and can I test them against my target before committing. Those determine outcomes. The generation label does not.
We would rather write that plainly than sell a tier on a distinction the destination server cannot observe.
When 5G Does Not Matter to You
Several common situations where the difference is genuinely irrelevant.
Ordinary browsing, messaging and streaming. Good 4G handles all of it comfortably. Video streaming is limited by the service's own bitrate, not by available bandwidth, and pages have not become twenty times larger. If your experience is fine, upgrading solves nothing.
You are in a low-band coverage area. Your 5G indicator is showing a coverage-optimised band that performs roughly like 4G. Paying more for it — in money, device cost or battery — buys a label.
Your bottleneck is elsewhere. Slow servers, congested backhaul, an overloaded home router, a distant origin. A faster radio link does not repair a slow chain, and identifying the actual constraint takes a few minutes.
You are running a mobile proxy for acceptance rather than throughput. As above: the destination cannot see the generation. Spend the effort on carrier diversity and request behaviour instead.
Battery life matters more than speed. For devices running continuously, pinning to 4G is sometimes the better engineering decision, particularly at the edge of 5G coverage where oscillation costs more than either mode alone.
You are on a metered plan. Faster networks encourage heavier use, and data allowances did not scale twentyfold. This is a genuine and frequently expensive surprise.
5G is worth caring about when you are in a well-served dense area, when you need substantial uplink, when latency consistency matters to what you are doing, or when you are deploying anything at industrial scale in a controlled environment. Outside those, the honest answer is that it is a background improvement rather than a decision.
People Also Ask
What is the actual difference between 4G and 5G?
By specification: 4G required 1 Gbit/s peak downlink and under 10 ms radio latency; 5G requires 20 Gbit/s peak downlink, 10 Gbit/s uplink, 4 ms latency for broadband use and 1 ms for ultra-reliable use, plus support for a million devices per square kilometre. In practice the meaningful changes are better uplink, more capacity under load, and more consistent latency.
How much faster is 5G than 4G really?
The peak requirements differ twentyfold, but both are ceilings measured under ideal single-user conditions. The specification's own "user experienced" target for 5G is 100 Mbit/s downlink in a dense urban environment, which is a far more realistic figure. Actual results depend mostly on which band you are connected to.
Why is my 5G no faster than 4G?
Almost always because you are on low-band 5G, which trades speed for coverage and performs similarly to good 4G. It can also be cell congestion, distance from the tower, being indoors, carrier traffic management, or a bottleneck beyond the radio entirely.
Is 5G latency really 1 millisecond?
Not end to end. That figure is the radio network's contribution only, for ultra-reliable communications, measured with a single user, unloaded conditions and a minimal packet. Your actual round trip includes backhaul, internet routing and server processing, which usually dominate.
What is the difference between low-band, mid-band and mmWave 5G?
Frequency traded against range. Low-band travels far and performs roughly like 4G. Mid-band is the practical compromise and where most real improvement lives. Millimetre wave is extremely fast over a few hundred metres and is blocked by walls. All three display as "5G".
Do 5G proxies work better than 4G proxies?
For throughput and latency on the connection itself, somewhat. For getting a page, no — a destination server sees an IP address and its carrier, and cannot determine which radio generation the device used. What matters is the carrier, how the address is shared, and whether your traffic behaves plausibly.
Should I turn off 5G to save battery?
Sometimes. 5G generally uses more power, and at the edge of coverage a device may oscillate between generations, which costs more battery than staying on either. For continuously running devices, pinning to 4G is a reasonable choice.
Will 4G be switched off?
Not imminently. 5G deployments still rely on 4G for fallback and for coverage the higher bands cannot economically reach, and enormous numbers of devices — particularly industrial and IoT equipment — are 4G only. Carriers have been retiring 3G; 4G is a much larger and longer commitment.
Wrapping Up
The specifications are clear and public: 4G had to reach 1 Gbit/s peak and 10 ms radio latency, 5G has to reach 20 Gbit/s downlink, 10 Gbit/s uplink, 4 ms for broadband and 1 ms for ultra-reliable use, and a million connected devices per square kilometre.
The specifications are also, deliberately, not descriptions of your phone. Peak rates assume ideal conditions and a cell to yourself. Latency figures measure the air interface alone. The specification's own realistic target — 100 Mbit/s downlink for a typical dense-urban user — is two hundred times below the number that appears in advertisements, and it is the one to remember.
What actually determines your experience is which band you are on. Low-band 5G performs roughly like good 4G and is what most wide-area coverage consists of. Mid-band is where the genuine improvement lives. Millimetre wave is spectacular within a few hundred metres of a transmitter and irrelevant beyond it. All three show the same two characters on your screen.
The change that will matter most over time is not speed at all. It is connection density and reliability — the requirements that turned a phone network into something a factory or a utility can build on.
And on our own product, the thing we would most like to leave you with: a website cannot see which radio generation you used. It sees an address and the carrier that owns it. That makes the difference between a 4G and a 5G mobile proxy a question of throughput, not of whether your request gets through. If a provider is charging a premium on the implication that 5G makes traffic more acceptable, they are charging for something the destination server has no way to observe — and the questions worth asking instead are which carriers, how the addresses are shared, and whether you can test them on your own target before you pay.
