The paper presents the concept of local and metropolitan wireless mesh networks operating in millimeter-wave band. These self-organizing networks may be used as the high-throughput backbones for emerging 5G communication systems, as well as standalone networks providing extensive QoS, mobility, reliability and ultra-high throughputs for the connected users. The paper observes the current state and the prospects of the development of the millimeter-wave mesh networks. The paper outlines the network logical structure including MAC level design, routing and resource allocation. The problem of delay-optimal scheduling within Spatial TDMA is formulated, and a simple fast algorithm for scheduling is proposed. The experimental results provided prove the algorithm allows to utilize the network resources at very high rates while building scheduling sufficient for delay-critical applications.
