The disclosed technology provides a system and method for allocating frequency bands to a mobile device or user equipment (UE) based on priorities assigned to the different frequency bands. When no priority is assigned to the frequency bands, when a special or reserved priority is assigned, or when equal priority is assigned, the frequency band allocation to the UE is based on a default frequency allocation algorithm (e.g., based on a relative bandwidth of the different frequency bands).
