Experimental investigations by have been done to understand co-channel interference characteristics between the small cells installed in indoor environments. However, there are a lot of complex situations in the arrangement of indoor small cells, so that it seems to be hard to build the general interference modeling through experimental results due to strong dependences on the environmental conditions...
In Heterogeneous network, a number of small cells are distributed in conventional macro-cellular environments, in order to improve the communication speed. The interference between outdoor and indoor cells then becomes to be a significant problem, so that its propagation loss characteristics should be evaluated in outdoor- indoor propagation environments. This paper proposes a mathematical expression...
