2.4 ghz vs 5ghz on wifi bands?

What are the differences between the two? Just curious. Some of my devices support 5ghz while others support 2.4 ghz.

5 is newer, so not all devices are able to connect to it. But in short.

2.4 - more range, but not as fast speeds.
5 - less range, more faster or can do faster speeds.

If a 5ghz Wifi Adapter goes on sale, I may consider getting a couple. Unfortunately, this is not possible right now as upcoming events require lots of money Smiley Very Happy

Well don't go jumping straight to purchasing a adapter unless your paying for those internet speeds. Generally 2.4 can do a max of about 70mbps. Anything above 70 would need 5ghz.

I do have over 100 on my internet connection. I hardwired to the router to see the difference and it was there.

Re: 2.4 ghz vs 5ghz on wifi bands?

2.4 GHZ has 3 overlapping bands.  

5 GHZ has 23 non overlapping bands.  which results in a cleaner signal.

 

For general purposed 2.4 GHZ is more than sufficient for regular web use.

 

5 GHZ will result in better quality and speed for streamig video and multiplayer gaming and anything where packet loss and other delays are more of a factor.

 

I recently purchased a dual band router that I have hooked up to 8 devices in my home and the results were immediatly noticable.  

 

My gaming computer and Xbox are hooked up to the 5 GHZ and other low end devices like apple products, Android phone and my printer are hooked up to the 2.4.  

 

But for best performance you are always going to want a gigabit ethernet connection to devices.

Re: 2.4 ghz vs 5ghz on wifi bands?

Sounds like a great discussion on this. I was only focusing on one device, the HP Stream. My Roku only supports 2.4 ghz so I'm not concerned like that. My HP Stream has a flaky Wifi card built in that works "OK" for most things and I have it connected to my Dynex 16" LED TV to play some steam games in the bedroom but the download speed is limited to 20 megs and not as if I had a wired connection. I can forget the broadband power adapters as they are very expensive. So once I arrive in Sacramento this weekend I think I may check out the Best Buy in Citrus Heights to see if they have any good deals in there on open box items if there is any that is. I can live with the 2.4 ghz as the connection is stable and does not drop out. but I would love the 5ghz speed if I'm able to.
