This document contains an internal assessment test for an Electronics and Communication Engineering course on wireless networks. The test has three parts: Part A contains 10 short answer questions about topics like SIP, MANET characteristics, Adhoc vs. cellular networks, IPv6 features, routing, UMTS, UTRAS, UTRA operation modes, uplink operations, and 3G SGSN vs. GGSN. Part B has 5 longer answer questions requiring explanation of IPv6 and SIP, MANET discovery and processes, UMTS channel structure, UMTS protocols, and an UMTS overview. Part C consists of 1 question requiring a detailed response with diagram about MANET routing, UMTS core architecture, or 3G
