[ILUG-BOM] [OT] What are sms gateways?

[ronit khan]

I would like to know what are sms gateways.
How do people at Indian Idol process incoming sms's.
Is any special hardware required ? 
What is a Gsm modem ?
If I ask Airtel or Orange to provide me a gateway,
will they give me some special hardware or a sim card
?
I need all this info for my project.
I will be using gnokii for this.
I will be developing this application on Linux.
Thank you for your help. :)
