Infrastructure sharing encompasses almost all the ways in which the operators could share the mobile network. This includes issues on land or property sharing, right of way, secondary spectrum sharing and many others. Regulators in general encourage passive infrastructure sharing. Sharing can speed up network deployment, enhance competition and save the operators from huge investment. Issues of public opposition against construction of new sites with wireless communication masts, or fear of exposure to electromagnetic fields around antennas also influence the regulatory decision making process.
In TRAI’s recommendations on Infrastructure sharing, they have discussed three main components: passive infrastructure sharing; active infrastructure sharing; and financial and economic measures for infrastructure sharing. TRAI’s recommendations recognized an “urgent need” for passive infrastructure sharing. TRAI recommended permitting the sharing of a broad array of active infrastructure, though not spectrum; it also recommended limits on the types of permissible backhaul sharing. TRAI also set out a variety of recommendations related to creating incentives for sharing in urban and rural areas.

BEREC report on Infrastructure and spectrum sharing - this document is a report on infrastructure and spectrum sharing in mobile / wireless networks. The report analyzes the situation in Europe, based on the answers from 16 RSPG/BEREC members to a questionnaire circulated in 2010 amongst NRAs and administrations.
Critical factors for the expansion of broadband in developing countries: The case of Peru - the purpose of this paper is to understand and identify the critical success factors for the development of broadband services in a developing country context, using the case of Peru. Through a MACTOR analysis the authors found that the objectives of sharing infrastructure, the further deployment of infrastructure and the development of competition in the market for broadband services are the main success factors.
