Abstract:
Mobile telephony exhibits transmission characteristics and user-interface features distinct from traditional telephony. To study these differences in systems designed for use in commercial airplanes, trains, and automobiles, we used a variety of techniques, including both laboratory and field observations. We found that mobile telephony, viewed from the user's perspective, is quite different from traditional telephone service. In the present paper, we review the assessment techniques that we employed, and consider their strengths and weaknesses for characterizing the performance of mobile tele

Abstract:
In mobile phone supply chains, consumers can choose handsets and telecommunication services as a bundled package or buy handsets and services independently. This article develops a multi-agent simulation model to explore price, subsidy and bundling decisions for competing mobile phone supply chains with network externality, where each chain includes one mobile phone manufacturer and one service operator. There are two bundling strategies: free or bundled. The results indicate that: 1) if the impact of network externality is not too small, then competitive differentiation can be formed when one

Abstract:
This paper investigates the Carrier Current Line Systems (CCLS) technologies of Machine to Machine (M2M) architecture which applied for mobile station coverage working with metro, high speed railway, and subway such as analysis for public transport of an indoor transition system. It is based on the theory and practical engineering principle which provide guidelines and formulas for link budget design to help designers fully control and analyze the single output power of uplink and downlink between Fiber Repeaters (FR) and mobile station as well as base station. Finally, the results of this lea
