A tiered service management resource providing management of wireless channels in a network environment receives notification of wireless bandwidth such as multiple wireless channels allocated by a spectrum access system (a.k.a., SAS). The spectrum access system allocates the wireless channels for use by a wireless base station in the network environment. Prior to re-allocating the wireless bandwidth (such as a selected wireless channel) to customer premises equipment, the tiered service management resource further receives a communication indicating a wireless spectrum scan performed at a location from which customer premises equipment in the network environment is (being) installed to wirelessly communicate with the wireless base station. Based on an identified fixed wireless service tier (or level) assigned to the customer premises equipment and supplemental information such as the wireless spectrum scan, the tiered service management resource allocates a selected wireless channel from SAS-assigned bandwidth for use by the customer premises equipment.
