【Abstract】Neutral host SCPs represent a key element of the 5G vision of ultra-dense mobile networks. However, current business models mostly focus on multi-year agreements for large venues, such as stadiums and hotel chains. These business agreements are regulated through binding SLAs, which tend to be too cumbersome and costly for smaller-scale SCPs. As a result, the neutral host model does not scale up to its full potential. In this article, we propose a framework to enable the participation of small- to medium-sized players in the cellular market as providers offering network resources to MNOs. To this purpose, we review the current and emerging spectrum and technology opportunities that SCPs can use for neutral host deployments. We also propose the use of blockchain-enabled smart contracts as a simple and cost-efficient alternative to traditional SLAs for small-scale SCPs. To demonstrate this, we describe a proof of concept implementation of an Ethereum-based smart contract platform for best effort service between an SCP and an MNO. Our simulations on potential smart contract-based deployments in city center Dublin show that the received signal strength in the considered area will increase by an average of 10 percent.
