Wireless Networks Questions Medium
A wireless network protocol data unit (PDU) refers to the basic unit of data that is transmitted over a wireless network. It encapsulates the information being transmitted, including the payload data and control information necessary for the successful delivery of the data. The PDU format and structure vary depending on the wireless network protocol being used, such as Wi-Fi (802.11), Bluetooth, or cellular networks (GSM, CDMA, LTE). The PDU typically includes headers, trailers, and other control information that enable the wireless devices to communicate and exchange data efficiently and reliably.
