Which antenna 2.4 or 5Ghz for range extender.

read the specifications on your particular model choice. Most are backward compatible.
What make and model are you looking at?

It really depends on which flavor(s) of 802.11 (WiFi) you'll be connecting to. Thee most common are a, b, g, n and ac.

See the table in Wikipedia

Morning,


Working on wifi range extender and wanted confirmation on the frequency range of the antenna. Wanting to buy a 15dbi antenna and I presume most locations are still on the 2.4. Or does it really matter?

Thanks in advance for you input.

2.4 definitely.

if you're planning to use it to lock onto campground / resort wifi, 9 times out of 10 they'll be using 2.4 ghz.

if you're planning to use it to extend a MiFi / Hotspot of your own, 9 times out of 10 they use 2.4 ghz as well.

It is my observation, the fewer bands an antenna supports, the better it will work.

I think 2.5 is the most common but sure as you buy one you will need a 5Gig, Best option is one of each.

Some do both, but it is a jack of all trades, master of none. If you are going for peak gain, you need one of each. All of the campground wifi I have ever been to were 2.4. I prefer 5g, as there is usually no one on it. For example, at my office there are ~10 2.4 access points I can pick up from my desk, but only 2 5g, both are mine. At home I am looking at 15 2.4 access points, 3 are mine (1 is Comcast, one is my adt pulse, one is my outside access point). My access point is the only 5.8 I can pick up from here.

2.4 travels farther, and penetrates walls, trees, etc better. 5.8 is far faster, as you don't have to share the airwaves with anyone usually)

check out L-com . That is their speciality.

your better off with a directional panel antenna then a 15 dbi omni .

2.4 almost no one is using 5.8 for the end devices

dont forget extender needs to be design for frequency, either 2.4 or 5.8 or both if it supports it

Actually its amazing how many devices are 5.8 capable these days. I've moved everything I can up to 5.8. BUT I haven't seen any routers that don't have 2.4GHz whether or not they have 5.8GHz

It is 5g, not 5.8, the 2.4 spans from about 2.402-2.472 ghz, the 5g from 4.92 to 5.825 - with a lot of gaps. Mostly 5g is from 5.18-5.32 ghz & 5.745-5.825 ghz. Some equipment allows 5.5-5.7 ghz.

On my trailer, I put a bullet with a onmi on the roof, and a dual band router inside to repeat the signal.

Semantics...
You're obviously well versed in whats where and most certainly know that that entire band, whatever you want to call it is referred to as 5.8 even though thats the top end
