5G vs 4G : les principales différences entre les réseaux expliquées | Tendances numériques (2023)

FAQs

Is there really much difference between 4G and 5G? ›

5G up to 100 times faster than 4G

In the right conditions 5G download speeds can reach 10 gigabits per second. That's up to 100 times faster than 4G – and certainly the level of performance needed for an increasingly connected society.

5G can act as many different networks

While 4G networks were mostly designed for phones, 5G networks were designed for much more flexible use, replacing the need for many special-purpose networks. They can even function as many separate networks – all at the same time. This cool 5G technology is called network slicing.

The three major differences between 4G and 5G are faster speeds, higher bandwidth and lower “latency,” or lag time in communications between devices and servers.

Low level of Latency

Latency is the time gap between the command and response of the network. The 5G technology promises very low latency of near 5 milliseconds, while 4G latency ranges from 30 ms to 100 ms. This will boost the technologies which require quick response time.

With 5G, you can expect higher download speeds when using mobile data, lower latency (the time it takes for a device to respond to information or an action), increased reliability and more network capacity. Basically, 5G is faster and more stable than 4G, and it's capable of connecting a lot more devices.

Is it OK to buy a 4G phone in 2023? 4G phones still work on 4G LTE networks for now, but eventually they will become obsolete. Consider how long you plan to keep your phone; if you plan to keep your phone for longer than a year or so, it might be a good idea to get a phone that is 5G compatible.

Disadvantages of 5G Technology

Many of the old devices would not be competent to 5G, hence, all of them need to be replaced with new one — expensive deal. Developing infrastructure needs high cost. Security and privacy issue yet to be solved.

Emerging 5G networks feature lower latency, higher capacity, and increased bandwidth compared to 4G. These network improvements will have far-reaching impacts on how people live, work, and play all over the world. Emerging 5G networks feature lower latency, higher capacity, and increased bandwidth compared to 4G.

While spending more money on a 5G phone or a 5G variant of the same device may seem like a good, future-proof idea, it will not be worth it if you don't have the coverage and budget for 5G plans. Note that while 5G data plans may be priced equal to 4G in the beginning, they can quickly climb up for the faster service.

Will 4G phones work on a 5G network? You must have a 5G-capable phone to access a 5G network. Older 4G devices without 5G radios will not connect to 5G networks.

Is 5G better than LTE? ›

One of the most significant advantages of 5G over LTE is that it offers much lower latency and faster download speeds. 5G networks can achieve these speeds because they operate at higher frequency bands than LTE networks. The higher the frequency waves, the more data can be transmitted in a given amount of time.

Simply put, 4G towers are the large masts with numerous antennas that can be found throughout the country. 5G towers are unobtrusive boxes that are frequently mounted on utility poles. There are many more 5G towers than 4G towers, which are typically located in urban areas.

With faster speeds and low latency, a 5G cellular connection also provides broader signal coverage at all times.

Verify that there is 5G coverage where you are. Yes, 5G is everywhere, but there are still huge gaps in the network which means you won't always have coverage. Your 5G capable phone will always find a signal and connect if 5G. If it isn't available, your phone will revert back to LTE or 4G.

The shorter wavelength means 5G can carry a lot of data much faster than 4G, but it also means a much shorter range. 4G wavelengths have a range of about 10 miles. 5G wavelengths have a range of about 1,000 feet, not even 2% of 4G's range.

Similar to the legendary switch from wired dialup to high-speed broadband, we will rethink what mobile data can do. That said, there is one major downside keeping 4G from being entirely replaced right now: 5G is hard to install and deploy. More transmitters are needed to cover the same area as current 4G networks.

If your carrier doesn't support 5G roaming, you can get cellular data through 4G or LTE networks or obtain a local SIM card or eSIM with 5G where available.

Within the U.S., it's reasonable to assume that by the end of 2022 there will not be a single major carrier supporting 2G. The same fate awaits 3G. 4G LTE operates under a different scenario, and we can confidently say that 4G will be around for at least another decade.

half of U.S.A. will have access to 5G. By the year 2024, only half of Americans will actually own a 5G phone or other devices. No, 4G LTE shutdown will not be happening for atleast a decade. Therefore, the thing to remember is that 4G will not be going away anytime soon, regardless of how fast the 5G network grows.

T-Mobile announced that it finished shutting down Sprint's 3G CDMA network as of March 31, 2022 and Sprint's 4G LTE network as of June 30, 2022.

What are the pros and cons of 5G phones? ›

5G can provide simultaneous connectivity of up to 1 million connections per square kilometer. This dense connectivity is key to implementing advanced massive IoT applications. Mission-critical applications like remote intensive care units demand reliability and speed.

The main advantages of the 5G are a greater speed in the transmissions, a lower latency and therefore greater capacity of remote execution, a greater number of connected devices and the possibility of implementing virtual networks (network slicing), providing more adjusted connectivity to concrete needs.

Most people will want a smartphone with 5G onboard, for longevity's sake at the very least. We're coming up to four years since the Galaxy S10 5G came out and genuinely needed the special tag at the end of its name. The tag isn't needed in 2023.

5G can be significantly faster than 4G, delivering up to 20 Gigabits-per-second (Gbps) peak data rates and 100+ Megabits-per-second (Mbps) average data rates. 5G has more capacity than 4G. 5G is designed to support a 100x increase in traffic capacity and network efficiency. 5G has lower latency than 4G.

Technical and physical limitations. Although 5G mmWave is super fast its wavelengths have short and weak penetration through physical objects such as walls, doors, trees, etc.

4G will Peak in India in 2024

By the end of 2028, 4G subscriptions would dip to 570 million in India. At the same time, in 2028, 5G subscriptions in the country would reach 690 million, meaning that 5G would have a bigger market share. Still, 4G would drive a significant amount of revenue for the telcos in 2028.

We expect this to be completed by no later than December 31, 2022. This decommissioning effort affects 3G (CDMA) devices, 4G Non-VoLTE devices, and network extenders.

Vi SIM cards are 5G ready, and Vi 4G SIM cards will function well with your 5G phones. Thus current Vi users need not worry about converting their SIMs to be able to use 5G services. However, all erstwhile users can visit the nearest Vi stores to get your 5G ready Vi SIM cards.

Is LTE slower than 5G? ›

Low-band 5G: 5G low-band operates below 2 GHz and offers speeds roughly 20% faster than 4G LTE. This band uses spectrum that is already in use today and supports 5G devices on the market now.

This is where 5G stands head and shoulders above 4G. In theory, 5G is likely to reach speeds that are 20 times faster than 4G LTE¹. 4G LTE has a peak speed of 1GB per second; 5G could theoretically achieve speeds of 20GB per second.

4G is significantly faster. LTE offers only 100 Mbps, while true 4G offers up to 1,000 Mbps.

What Do 5G and 4G Towers Look Like? 5G towers tend to be smaller than their 4G counterparts. You'll find them placed closer together than 4G towers, about 500 to 1000 ft apart. They make use of different hardware called small-cell technology.

After the 150-meter mark, RF energy gets weaker. The distance needed to reduce exposures down to the General Public Precautionary Level of 100 microwatts per meter squared (μW/m²) is often around a quarter of a mile (1320 feet or 400 meters) or more.

So, why are some 5G connections so slow? The first, and most impactful, reason is that the far-reaching 5G signals that have powered the vast majority of carrier rollouts in the US – especially from AT&T and, to a lesser extent, T-Mobile – have used low-band carrier frequencies.

Yes, 5G has the potential to use more battery than 4G. This is especially true for first-generation 5G devices, which used inefficient modems.

The easy answer is no; You will not need a new SIM card for 5G. Most modern phones support both 4G and 5G, and switching to 5G is as easy as making sure your plan is 5G compatible.

How Far Does a 4G LTE Cell Tower Reach? The range of a 4G LTE cell tower is 2 to 4 miles (3 to 6.5 kilometers) when transmitting low- and mid-band spectrum.

Why is my 5G so slow? 5G rollout promised speeds 600 times faster than 4G networks. But, 5G connections are often slow due to less dedicated bandwidth for 5G networks vs. 4G or LTE networks, which are still more widely used.

Does 5G affect phone calls? ›

5G networks combine those blistering data speeds with almost zero lag connecting to the network. That could lead to video calls with pin-sharp resolution and minimal image buffering or freezing.

Within the U.S., it's reasonable to assume that by the end of 2022 there will not be a single major carrier supporting 2G. The same fate awaits 3G. 4G LTE operates under a different scenario, and we can confidently say that 4G will be around for at least another decade.

5G can be significantly faster than 4G, delivering up to 20 Gigabits-per-second (Gbps) peak data rates and 100+ Megabits-per-second (Mbps) average data rates. 5G has more capacity than 4G. 5G is designed to support a 100x increase in traffic capacity and network efficiency. 5G has lower latency than 4G.

5G isn't replacing 4G any time soon. In fact, they will coexist and work together. 5G-capable phones can actually use both 4G and 5G technology.

If you're looking for fast speeds with the most population coverage, LTE is the way to go. However, if you're looking for the latest and greatest technology with the potential for faster speeds and more capacity, 5G is the way to go.

The magnitude of this risk is compounded with 5G, as the network will be connected to a large number of devices, and critical systems and might create a single point of failure, opening the opportunity for malicious actors to attack multiple devices in different industries all at once.

By the year 2024, only half of Americans will actually own a 5G phone or other devices. No, 4G LTE shutdown will not be happening for atleast a decade. Therefore, the thing to remember is that 4G will not be going away anytime soon, regardless of how fast the 5G network grows.

With your 5GB of data, you'll be able to browse the internet for approximately 60 hours per month, to stream 1,000 songs online or to watch 10 hours of online video in standard definition. In this article, we'll discuss what you can do with 5GB of data and how long you can expect your 5GB allowance to last for.

Although 5G mmWave is super fast its wavelengths have short and weak penetration through physical objects such as walls, doors, trees, etc.

Is 5G faster than cable internet? 5G internet is capable of reaching higher wireless speeds than the wireless speed generations before it, but you're not guaranteed the highest speeds and certainly not the higher speeds than you'd get with a reliable cable connection.
