What is WDP?

- It is a network layer protocol for delivering datagrams over a wireless IP network.

- Wireless Datagram Protocol (WDP) works at the transport layer of WAP.

- WDP processes datagrams from upper layers to formats required by different physical datapaths like GSM SMS or CDMA Packet Data.

- WDP is adapted to the bearers available in the device so upper layers don't need to care about the physical level.

- It provides a common interface to the upper layer of the protocol stack.

Features of WDP:

- It provides a network and bearer independent interface to higher layers.

- It provides segmentation and re-assembly.
