Re: Dual Radio & Dual Band

Dual band means it will work on both the 2.4Ghz and 5 Ghz bands but not neccessarily at the same time.  A dual radio means that there are two radios in the access point so one can operate at 2.4Ghz and the other at 5Ghz.

Hi,

Just want to add some small bit of info: :smileyhappy:

One of the main benefits of using Aruba Access point with Dual Radio&Dual Band is the Band Steering feature:

Some access points have a single radio (AP93) that can be tuned to either a or bg

Some access points have two radios (AP105), and one can be tuned to a and one can be tuned to b/g

Thx ,

so AP like 93 can work on  either b/g  or a 

1-why is  "a"  separated from  "b/g"  ?

2-what about  "n" ?

3-is it better to work on  "a" or  "b/g" ?

Re: Dual Radio & Dual Band

you might want to do some general googling on wireless networks / radios / bands and such. there is lots of information out there.

 

quick answers

1) because a radio "works" on one or the other, a in 5ghz and b/g in 2.4ghz

2) n can work on the a 5ghz or b/g 2.4ghz, it brings some tricks for higher throughput

3) one could say a as it is less used, has more usable channels, and can do better channel bonding; but not all devices support it and the signal reaches less far, so with most things, it depends.
