Predictions for
wireless and mobile Internet access suggest an exponential traffic increase, particularly
in in-building environments. Non-traditional actors such as facility owners
have a growing interest in deploying and operating their own indoor networks to
fulfill the capacity demand. Such local operators will need spectrum sharing
with neighboring networks because they are not likely to have their own
dedicated spectrum. Management of internetwork interference then becomes a key
issue for high capacity provision. Tight operator-wise cooperation provides superior
performance, but at the expense of high infrastructure cost and
business-related impairments. Limited coordination, on the other hand, causes
harmful interference between operators, which in turn will require even denser
networks.
In this article, a
techno-economic analysis framework for investigating and comparing indoor
operator strategies is proposed.
A traditional network
cost model by introducing new inter-operator cost factors is refined. A numerical
example to demonstrate how the proposed framework can help us to compare
different operator strategies is then presented.
