Broadcasting Commercial Data on Mobile Peer-to-Peer Networks

In our visions of the future, end users rely on their mobile terminals to access a wealth of information, a sizable portion of which will be commercial. But providing the necessary bandwidth for this informa tion at a reasonable cost will be a challenge. However, the emergence of mobile terminals capable of communicating both with infrastructure networks like GPRS and UMTS and with each other in a peer-to-peer fashion opens up new possibilities for content distribution: the peer-to-peer networks, assisted with the infrastructure network, can be made to function as a broadcast channel for commercial data. In this paper we introduce the concept of using the mobile peer-to-peer networks for distributing commercial broadcast content, taking a news service as an example. In particular, we look at the economic possibilities and legal risks of implementing these services.
