We propose and study the feasibility of wireless quantum key distribution (QKD) in indoor environments. Such systems are essential providing access to developing communications networks. find a practical regime operation, where, presence external light sources loss, secret keys can be exchanged. Our findings identify trade-off between acceptable amount background receiver field view, where latter affects ease QKD system. In particular, we show that, using proper setting, provide mobility for users without imposing stringent conditions on beam steering.
