This work exposes and tackles the problem of providing wireless service to a mixed population of indoor and outdoor users using an outdoor cell-free massive MIMO (CF-mMIMO) network. Since cell-free networks are typically designed to provide near-uniform quality-of-service to all users, it is shown here that such strategy, when applied blindly to indoor and outdoor users, causes the network performance to dramatically degrade. A framework is then introduced that treats indoor and outdoor users separately in such a way that they both see their performance very significantly enhanced. In particular, user connectivity, power and pilot allocation are conducted for each user class senarately while preserving scalability.
