5、Purposes (TP) to test the BRAN HIPERLAN type 2; Data Link Control (DLC) layer; Part 1: Basic data transport functions. The objective of the present document is to provide a basis for conformance tests for BRAN HIPERLAN type 2 equipment giving a high probability of air interface inter-operability bet
