Evolution and Standardization of the Smart Antenna System for Software Defined Radio Seungheon Hyeon, June Kim, and Seungwon Choi, Hanyang University ABSTRACT Transitioning proprietary or legacy softwaredefined radio networks to open architectures,while often complicated, is increasingly critical to improve the interoperability and compatibilityamong SDR networks and the subsystems within those networks as well. With this in mind, two consortia, the SDR Forum and the Object Man-agement Group, have teamed to define an open Smart Antenna specification. This specification defines a model (including an API) that simpli- fies the integration of an SA subsystem into a traditional SDR network. The specification is called the “Platform Independent Model (PIM) and Platform Specific Model (PSM) for the Smart Antenna” or “SA API specification.” This article introduces the SA API, which provides a standard model and standard service of the SA system operating in SDR networks. INTRODUCTION Since the early 1980s, the wireless industry has rapidly grown through the development of multiple standards and technologies. Each wireless standard has evolved with its specialized service such as voice, video streaming, wireless Internet access, or email service. This rapid expansion compels customers (developers and end users) to use multiple devices for their various needs and reduces the life cycle of the devices. Customers prefer to use a single device for multiple services. On behalf of end-user requirements, manufacturers need to find a development technology that supports flexibility, portability, reusability, interoperability, and cost efficiency of their manufactured goods. The wireless industry (including the commercial, manufacturing, and defense domains) faces change in development due to changes in capabilities demands, standards, and tools supporting those standards. Software defined radio (SDR) enables a common radio platform to support multiple standards and services by
