This paper offers a description of a new transactional model designed for a m-commerce 4G architecture, and the economic benefit that it can bring to an organization. For the design, it has been used a Hub and Spoke transport model for the material flow, a Queuing model for the bank company transactions flow, and a LDPC/MIMO channel for the transmission environment. With the new system, the SNR...

T aim of this paper is to present a model structure that analyzes the hub-spoke network design issue within a competitive framework. Under deregulation, airlines have developed hub-and-spoke networks, enabling them to increase frequency by aggregating demand and to prevent entry into the marketplace by reducing airfares. While liberalization in the United States and Europe was undertaken to inc...

This note explores the extent to which airlines operating large hub-and-spoke networks secure a competitive advantage. More speci®cally, this paper explores the intricate relationship which arises among productive eciencies and pro®tability when the size of the hub-and-spoke network expands. To this end, Brueckner and Spiller (1991, International Journal of Industrial Organization 9, 323±342) ...
