Wireless Networks Questions Medium
The wireless network protocol stack refers to the set of protocols and standards that are used to enable communication and data transfer in a wireless network. It is a layered architecture that consists of multiple protocols, each responsible for a specific aspect of wireless communication.
The protocol stack typically includes the following layers:
1. Physical Layer: This layer deals with the transmission and reception of wireless signals. It defines the hardware and radio frequency specifications for wireless communication.
2. Data Link Layer: This layer is responsible for establishing a reliable connection between devices in the network. It handles tasks such as error detection and correction, flow control, and medium access control.
3. Network Layer: The network layer is responsible for addressing and routing data packets across the wireless network. It determines the best path for data transmission and ensures efficient delivery.
4. Transport Layer: This layer provides end-to-end communication between devices. It ensures reliable and error-free data transfer by segmenting and reassembling data packets, as well as handling congestion control and flow control.
5. Application Layer: The application layer is where user applications and services interact with the wireless network. It includes protocols such as HTTP, FTP, SMTP, and DNS, which enable various applications to communicate over the wireless network.
Each layer in the wireless network protocol stack performs specific functions and relies on the layer below it for support. Together, these protocols enable seamless wireless communication, allowing devices to connect, exchange data, and access network services in a wireless network environment.
