5G mmWave wireless backhaul, or as some refer to it, wireless transport, is a means for connecting Sub-6 gNBs or LTE eNBs to your existing core network system in a wireless manner. Compared to traditional, fiber-based solutions, there is no need for cable infrastructure, which allows for cost-efficient and fast deployment.
5G mmWave Backhaul is a perfect way to drastically increase the capabilities of existing LTE/5G Sub-6 Ghz infrastructure, expanding it or facilitating greenfield deployments.
