CISCO AP with 2.4GHz antenna now having throughput problem

Question

Hi all expert,
Current i'm having problem with my AP running with WLC. For example, 1 AP in a room with 30 users, they are having throughput/slow connection problem.
Just want to know, if we dun add another AP but instead add-in 5GHz antenna, will it improve the conectivity or it will be the same ?? If there is other solution that incur lower cost will be helpful as well..
Regards,
DericT

i'll need to test it out 1st .. definitely its older model AP with only FE .. Hopefully with 5Ghz antenna will solve the problem.
Mmmmmm ... Not it won't.    You just might make it alot worst.
Think about it before throwing good money:  2.4Ghz is low speed but long range (check!).  You have 30 clients all going to ONE AP over a FastEthernet connection (check!).  Next, due to the overwhelming amount of client traffic resposes slow down (check!).  Next you want to put all the clients into 5.0 Ghz radio but still on a FastEthernet link, which is HIGH speed but short range.
Still doesn't make sense?
Try this:  Think of the situation as driving along a narrow, pot-holed riddled dirt road with your, say, VW Golf.  Your intention is to run this strech at high speed while carrying the entire football team behind you.  Your solution is to remove the VW Golf engine and stick the engine of a Caterpillar D10T under the hood/bonnet.  (How the heck you'll be able to fit the monster in is a marvel of technology by itself!)
