Network hardware devices organized in a Wireless mesh network (WMN) in which the network hardware devices cooperate in distribution of content files to client consumption devices without Internet connectivity are described. One mesh network device includes a housing with a first sector defined by a first recessed region between a first reflective wall, a second reflective wall, and a third reflective wall, and a second sector defined by a second recessed region between a fourth reflective wall, a fifth reflective wall, and a sixth reflective wall. A first antenna, such as a phased array dipole antenna, is disposed inside the first recessed region. A first radio, which is coupled to the first antenna, causes the first antenna to radiate electromagnetic energy in a first frequency range and the first, the second, and the third reflective walls collectively reflect the electromagnetic energy, radiated by the first antenna, in a first direction away from the housing.
