Wireless broadcasting

I by chance captured the traffic flowing from my wireless interface and I was surprised to see that traffic of all the users on the wireless router was hitting my wireless, or the wireless router was broadcasting the data. It was something new for me, we always use wireless ‘routers’ so I was of the view that it would also behave like a router and not like a hub , which broadcasts all the traffic to all the hosts in the network.

Anyway a few quick search on Google revealed that , this is a well known fact about wireless routers, that they do broadcast wireless traffic.
I was only worried about it as it has lot of security considerations, passwords for applications like FTP and telnet are not sent in encrypted form , so anyone on the same wireless network can easily snoop on any passwords entered through the wireless.
