To increase the network capacity demands cellular operators have to add sites, use technology with a high efficiency spectrum, and increase spectrum allocation. The limited frequency spectrum becomes an obstacle for operators in increasing the availability of system capacity, which in turn can reduce the quality of mobile broadband services. Indonesian cellular operators are expected to have a spectrum deficit of around 400 - 450 MHz in 2020. One way to overcome spectrum deficits is consolidation between cellular operators. It is therefore very interesting to conduct a consolidation research of Indonesian operators and evaluate and analyze their impact on reducing spectrum deficits and competition. In this research the consolidation design was carried out with the following provisions: a maximum of two operators, migration of spectrum two of the consolidated operators that were not contiguous was carried out to a minimum, the consolidated spectrum of results is a contiguous frequency, and no spectrum divestment. The consolidation scenario of Indonesian cellular operators is simulated on operators namely Tsel, XL, Isat, and H3I operating at frequencies of 900, 1800 and 2100 MHz in six regional mobile broadband services namely Sumatra, Java, Bali Nusa Tenggara, Kalimantan, Sulawesi and Maluku Papua. There are three consolidation scenarios. Scenario I consolidation consisted of H3I+Isat consolidation, XL+Tsel, scenario II consolidation consisted of H3I+XL consolidation and Isat+Tsel consolidation, and scenario III consolidation consisted of H3I+Tsel and Isat+XL consolidation. First evaluated consolidation which gives the least spectrum deficit. Then the consolidation scenario is evaluated using company operational and financial data to decide which operator consolidation provides efficiency and fair competition. It can be shown from the results that the best technically consolidated operators may not necessarily provide good financial results.
