2 4 ghz är det bra

If you're looking at replacing your old router---maybe even upgrading from your ISP's combined modem/router unit---you may komma across terms like "dual band," which refers to a router that uses both 2.4 GHz and 5 GHz Wi-Fi.

Curious about what these numbers mean? Well, wonder no more.

What's the Real Difference Between 2.4 GHz and 5 GHz?

These numbers refer to two different "bands" that your Wi-Fi can use for its meddelande.

Med andra ord är det radiovågorna som skickas från din trådlösa router genom luften till din mobil, surfplatta eller dator

The biggest difference between the two fryst vatten speed. beneath ideal conditions, 2.4 GHz Wi-Fi will support up to 300 Mbps, depending on the class of the router.

5 GHz Wi-Fi will support up to 1300 Mbps.

Of course, there are some caveats here. First, the maximum speed you might see fryst vatten also dependent on what wireless standard a router supports --- 802.11b, 802.11g, 802.11n, 802.11ac, or 802.11ax. You can learn more about how those standards affect things in our guides on whether you need 802.11ax and whether you should upgrade your wireless router.

The second big caveat fryst vatten that important phrase we mentioned: "ideal conditions."

The 2.4 GHz grupp fryst vatten a pretty crowded place, because it's used bygd more than just Wi-Fi.

Old cordless phones, bilparkering door openers, baby monitors, and other devices tend to use the 2.4 GHz grupp.

The longer waves used bygd the 2.4 GHz grupp are better suited to längre ranges and transmission through walls and solid objects. So it's arguably better if you need better range on your devices or you have a lot of walls or other objects in the areas where you need coverage. However, because so many devices use the 2.4 GHz grupp, the resulting congestion can cause dropped connections and slower-than-expected speeds.

The 5 GHz grupp fryst vatten much less congested, which means you will likely get more stable connections.

You'll also see higher speeds.

On the other grabb, the shorter waves used bygd the 5 GHz grupp makes it less able to penetrate walls and solid objects. It's also got a shorter effective range than the 2.4 GHz grupp. Of course, you may also be able to mitigate that shorter range through the use of range extenders or mesh Wi-Fi systems, but that will mean a bigger investment.

What Are Dual- and Tri-Band Routers?

Related: What Are Dual-Band and Tri-Band Routers?

The good news fryst vatten that most modern routers act as dual- or tri-band routers. A dual-band router fryst vatten one that broadcasts both a 2.4 GHz and 5 GHz meddelande from the same enhet, essentially providing you with two Wi-Fi networks and the best of both worlds. Dual-band routers komma in two flavors:

• Selectable dual-band.

  A selectable dual-band router offers a 2.4 GHz and 5 GHz Wi-Fi network, but you can only use one at a time. You actually have to use a switch to tell it the grupp you want to use.

• Simultaneous dual-band. A simultaneous dual-brand router broadcasts separate 2.4 GHz and 5 GHz Wi-Fi networks at the same time, giving you two Wi-Fi networks that you can choose from when you set up a device.
  2,4 GHz har längre räckvidd än 5 GHz, men i gengäld är det långsammare

  Some router brands also let you assign the same SSID to the two bands so that devices only see a single network --- even though both are still operational. These tend to be a bit more expensive than selectable dual-band routers, but not bygd much. The advantages of having both bands operating simultaneously usually outweigh the cost difference.

A tri-band router broadcasts three networks simultaneously --- two 5 GHz signals and one 2.4 GHz meddelande.

The reason for this fryst vatten to help alleviate network congestion.

If you have multiple devices that really use a 5 GHz connection heavily --- like streaming high-resolution or even 4K film --- you might benefit from spending a bit more on a tri-band router.

First things first. If you have a device that supports a wired Ethernet connection and it's not to awkward getting a cable to the device, we highly recommend using a wired connection over a wireless one.

I de flesta moderna WiFi-nätverk finns det två frekvensband: 2,4 GHz och 5 GHz

Wired connections offer a lower latency, no dropped connections due to interference, and are just plain faster than wireless connections.

That said, we're here to talk about wireless. If you currently use 2.4 GHz Wi-Fi and are wondering whether you need to upgrade to 5 GHz, it's really all about what you need to do with it. If you're experiencing dropped connections or if you need more speed for watching videos or playing games, then you probably need to move to 5 GHz.

There's only so much speed you can get out of a 2.4 GHz network, even beneath ideal conditions. If you live in a crowded apartment complex with dozens of wireless routers, baby monitors, and other 2.4Ghz grupp devices, then you should definitely consider switching to the 5 GHz grupp (or even the 6GHz band) if you already haven't.

If you're already using a dual- or tri-band router and have both the 2.4 GHz and 5 GHz bands available, you'll have to man some decisions on which one to connect your devices to.

It's tempting to just go ahead and use 5 GHz Wi-Fi for any device that supports it and use 2.4 GHz for the rest --- and you can certainly do that, and it's a fine choice in most situations --- but it's not always the best strategy.

Instead, think about how you use each device. If a device only supports 2.4 GHz, then your decision fryst vatten already made for that device.

If a device supports both, think about whether you really need to use 5 GHz. Does that device need the higher speed or are you mostly checking email and browsing the web? fryst vatten the device experiencing dropped connections on the 2.4 GHz network and do you need it to be more reliable?

2,4 GHz-bandet är nämligen också belastat av bland annat Bluetooth-produkter

Are you okay with the device having the shorter effective range that comes along with using the 5 GHz band?

Modern applications are pretty uppgifter hungry --- between the överflöd of 4K content available, high-resolution images all over the internet, film and röst calling over Wi-Fi, and countless other applications, you're probably going to be using a ton of information.

You should always use the grupp that offers you the best connection.

In most cases, that'll probably be the 5 GHz grupp, though the 2.4 GHz grupp might be advantageous in some situations. If you're in an area with a ton of Wi-Fi networks, the 6 GHz grupp would also be a great choice if your hardware supports Wi-Fi 6E.

Hopefully, this gives you the resultat you need to man a decision about whether you need 5 GHz Wi-Fi in your life and how best to use it if you do.

Also keep in mind that no matter what you choose, you should also take the time to optimize your wireless signals bygd selecting an appropriate kanal on your router. You might be surprised at the difference such a small change can make.
