Abstract : Wireless communication is the fastest growing segment of communication today. Short range wireless devices conformant with 802.15.4 or blue tooth technologies are slowly advancing to replace wired devices but still many technical challenges like robustness, reliability and speed in general need be addressed to face the challenges of the future. This paper evaluates the prohibitive issues of short range wireless technology for their rapid and efficient deployment in the real time applications. A case study of switch over from wired to wireless environment for a real time implementation for Indian Railways is presented. The work presents threshold LQI based connectivity confidence matrix which reduces the problems of formation of asymmetric link and shows improvement in reliability of the communication. The case study also highlights the necessity of application independent communication model paving a way to cost saving.
