a/b/g/n on Same AP

I have the following questions :

1-  What is difference between  "dual band "  &  "dual radio "  ? 

2 - Can  AP-93   have some users connected using  802.11b while others connected using   802.11g ?

2 - Can  AP-105  have some users connected using  802.11b while others connected using   802.11g ?

1) Dual-band means the radio is capable of operating in either the 2.4 or 5 GHz space (only one can be active). Dual-radio means the AP has two radios and can operate in both bands at the same time.

 

2 / 3) Yes, but remember that older devices will "slow down" newer devices because they take up more airtime for everyone.

Thx 

For 2/3 ,   only will slow down Others  , or  all users will be forced to use the same  .11 Technology ( slowest one )  ?

Since 802.11b transmissions eat up more airtime, all devices may experience slower speeds when b devices are active.

802.11b devices take much longer than an 802.11g device to send the same amount of data. So while the b device is trying to send or receive that chunk, the g device has to wait.
