Is wireless network having common interface to all network pcs?

Question

Hello friends,

As i am developing packets capture for wireless network i want to know that , Is wireless network having common interface to all network pcs?

Currently i am connected with LAN having network adapter "Intel(R) PRO/100 VE network connection".

when i bind socket to this interface i get only packets which come across "Local interface",unable to get packets from remote interface.

So i thought "Wireless Network Adapter" sharing with all network pcs and all packets come across "Single Network Adapter",so that i capture all packets within network premises.

Please suggest, am i on right way? or if having another solution.

Thanks in advanced
