NewBie - Quastion

[Ping Lee Quan]

I know this is probably a dumb question but i am new to teh wireless Dev.

I would like to establish teh "hello world" kind of transmision.
Can anyone tell em what are teh different components i need to load on my machin and what services i need to start with. i am reading a book on this stuff but it is VERY dry.

thanks in advance
