Characteristics of two alternative frequency channel assignment methods for TDMA wireless access systems

The author studies the characteristics of two leading candidates for the radio channel assignment method in personal communications services (PCS) systems: the quasi-static autonomous frequency assignment (QSAFA) method and the dynamic channel allocation (DCA) method. The author first describes channel planning, the QSAFA method, and the DCA method. The author then discusses the characteristics of these two methods in terms of link setup and automatic link transfer, synchronization requirement, implementation complexity for multiple service providers, spectrum efficiency and signal quality, and other relevant issues.<
