Abstract

Various embodiments are disclosed relating to traffic prioritization techniques for wireless networks. In an example embodiment, different priorities may be applied to uplink traffic and downlink traffic at one or more nodes or mesh points in a wireless network, such as within a wireless meshed network, for at least some traffic. In another example embodiment, a first set of QoS parameters may be used for uplink traffic while a second set of QoS parameters may be used for downlink traffic for one or more nodes within a wireless network, for at least some traffic. According to another example embodiment, local or intra-cell traffic may be prioritized differently than inter-cell traffic for a mesh point within a wireless meshed network, for at least some traffic. For example, local or intra-cell traffic may be prioritized over inter-cell traffic for a mesh point within a wireless meshed network.

Claims
