One of the solutions to realize Wireless-ATM integration is to use the TCPng/IPng. which is promising in the future global networks. Com- pared with the traditional TCP. TCPng will need to be developed describing the new header fields and formats. It would contain support for broad- band wireless networks as well as ATM networks. In this paper, the author proposes some solutions and aspects for the Wireless-ATM implementa-tion.
