Abstract:
The purpose of this paper is to present a vision for future mobile and wireless networks. The
vision, which we call
Networks without Borders
(NwoB), is based on a market-place of virtual network
operators which construct networks from a pool of shared resources (e.g. basestations, spectrum, core
network components, cloud resources, processing capabilities etc.). The resources will be sourced from
traditional industry players as well as crowdsourced from individuals. The paper describes this approach
from a value-chain perspective. The proposed value-chain is substantially different from the value-chain
models that are currently used to illustrate mobile and wireless networks. The economic imperatives
and innovation drivers for this approach are discussed. Early work showing the promise of this vision
is presented. This work focuses on diverse examples which advocate the removal of traditional and
historical restrictions on spectrum and infrastructure and move towards more dynamic use of shared
resources. In the first example we look at how frequency-division-duplexing (FDD) and time-division-
duplexing (TDD) restrictions on spectrum usage can be relaxed; we remove the borders between TDD
and FDD. In the second example we look at the aggregation and pooling of corporate infrastructure
which uses exclusive spectrum and removes the borders between different mobile operators. Finally
we look at the aggregation of user-deployed or crowdsourced infrastructure that opportunistically uses
spectrum and removes the borders between independently deployed hotspots. These are starting points
and the full realization of the vision will involve more dynamic access to spectrum and more extensive
sharing of infrastructure. Hence, the final part of the paper describes the resulting research challenges
