Providing LTE connectivity to rural areas in Africa is a very challenging task that has been addressed with many different solution-models over the years. One model that seems to offer a sustainable business case is based on the Google ‘Loon’ LTE project, which provides many advantages. This solution, however, has a major disadvantage in form of a limited coverage, especially within the homes where the wall attenuation disrupts the signal. This paper provides a solution to this problem in form of deploying a cheap, simple, and passive repeater that enables indoor communication. By simulating the LTE radio-link between a Google ‘Loon’ base station and a user positioned inside a home, it has been found that the passive repeater lowers the wall attenuation considerably and thereby enables indoor communication.
