Wireless LAN network

Hi,

I would like to setup a wireless network lab (want to have setup for
ieee802.11a/b/g standards support)

Where I plan to have a station -- PC having linux (kernel 2.6.18 or
above).

Here I intend to use wireless card (Broadcom's) : "BCM4311 AirForceâ„¢
54g® 802.11a/b/g PCI Express® Transceiver"

On the Access Point I intend to have a PC (Linux/Windows) connected to
a Cisco's "Aironet 1200 Series".

Want to have a clarification here that what is this single band
(Aironet 1200 Series) and first generation dual band (Aironet 1200AG
Series) difference. Will both of them work with the Broadcom device
mentioned above ?

tia,

Regards,
Udayan
