Data Rate Comparison during Handoff in GSM with Wireless ATM Networks
Brajesh Mishra, Sudeep Baudha, Amit Kumar Gupta · 2012
Wireless GSM has emerged as an important component of the broadband wireless network infrastructure. While GSM supports for different traffic characteristics and QOS requirements, WATM networks provide wireless extension to the ATM-based B-ISDN networks by adding mobility support functions. The implementation of WATM poses several problems like mobility management, radio access to network etc. This paper presents the literature survey of GSM and its handoff related issues. Handoff is basically related with GSM so that we can understand the required bandwidth and data rate. These parameters are compared with traditional and advance data rate bandwidth. The paper reviews ATM fundamentals and its benefits. It deals with GSM features, requirements, protocol architectures and the global activities AS per the requirement of higher access network user needs high speed that will surly increase with GSM network. The focus is made on the handoff related aspects of WATM and GSM. The handoff management operation, requirements, protocols, proposed solutions and open issues for research.
