Wireless Access

what is difference between AP is  Dula Band & AP is dula radio ?

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:

(Old screenshot - but it will explain the basic idea)

Have a lovely night. :smileywink:

So can AP work with some clients on  a  while with other on b/g , while others on  n ...... is this related to dual band ?

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" ?

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.
