Relaying access points and related business models for low cost mobile systems.

Abstract

In this paper we consider provisioning of high bit rate mobile services without the need of complex user terminals or deployment of a full coverage network with a very large number of traditional cellular base stations (access points) Existing broadband, Wireless Local Area Network (WLAN) and cellular solutions are combined with novel technologies such as ad-hoc network and Multiple-Input-Multiple-Output (MIMO) antenna systems in order to obtain high capacity links, highly flexible solutions and support for mobilityt. In the proposed solution we introduce an intermediate access point, or relay, that connects the end-user terminals to either a wireless or fixed network. Thus, a direct high bit rate connection between base stations and user terminals is not required, which would be beneficial both technically and cost wise. The proposed solution enables flexible rollout strategies and small-scale deployment for both traditional mobile operators and local access providers. The new type of equipment can also be owned and deployed by local actors like facility owners, hotels and private persons that imply possibilities for more flexible business models.
