WIFUND -7 – Frames

Welcome to the world of frames.
So what the hell is a frame, especially a wireless frame.
Give me a try, a frame is located at layer 2 of the OSI model. Do not muddle it up with a packet, packets are located at layer 3! The data link layer (2) is responsible for a reliable transportation of data between two devices.

In wireless networks, frames are so important because they give us information about what wireless networks are nearby, they’re control when it’s save to send data – because it’s a shared medium.
Carrier Sense Multiple Access with Collision Avoidance or CSMA/CA is the technique which controls the sharing of the wireless space.

There are several frame types:
Management: Beacons, Probes, Authentication and Association
Control: RTS, CTS, ACK
Data: the data – payload
