The proliferation of different wireless technologies has led to fragmentation of interfaces and APIs that are used to control and manage air interfaces and wireless links. The emergence of new networking and application concepts that support increasingly heterogeneous access methods, especially when combined with future cognitive radio technologies, significantly increase the already high complexity of development projects and software architectures. Dissimilar wireless interfaces also complicate the development of middleware components for higher layers of the protocol stack. In this article we present a new generic interface and API architecture that has been developed and prototyped in several different wireless platforms to address these problems. We introduce the basic framework of the architecture, and explain how generic and open interfaces can significantly lower development and deployment costs. The developed interface architecture can be seen as a lower level middleware, or as an enabling technology to implement different technology transparent network middlewares. We also briefly comment about prototyping and standardization status of technology. [ABSTRACT FROM PUBLISHER]

Wireless communication technology is constantly advancing with the primary objective being to improve the quality of service for the end user. Cognitive radio is a technology capable of advancing wireless communications to the next generation of intelligent devices. Integrating cognition into wireless applications such as dynamic spectrum access, radio resource management, wireless distributed computing, and even traditional protocol stacks has already been shown to provide benefits related to the communications quality of service. The majority of cognitive radio related research has been limited to theoretical frameworks and simulations or in a few cases, demonstrating prototype DSA devices on a small scale. In order to continue advancing in this area, larger-scale experiments that are reproducible and able to be moved beyond theoretical simulations are required. Virginia Tech has built a testbed for software-defined and cognitive radio related research for the purpose of rapid next-generation communication system prototyping using a medium scale size network of flexible wireless nodes. In this article we present the details of the development, design decision rationale, and deployment of this testbed in hopes that it will be both used by the research community, and duplicated and improved in order to further the development of the many different facets of cognitive radio research.

Gate arrays -- Usage, Radio equipment -- Evaluation, and Radio receivers -- Evaluation
The transition of field programmable gate arrays (FPGAs) from application-specific integrated circuit prototyping to embedded products is analyzed. This shift can be attributed to the advantages of the evolving FPGA technology, such as unique combination of size and power efficiency as well as field programmability. Based on software-defined receiver evidence, FPGAs are predicted to play a significant role in pragmatic paths toward the commercialization of software radio technology.

Mobile communication systems -- Europe
The Research for Advanced Communications in Europe program's second phase focuses on system integration and new services and applications prototyping. The international program consists of 92 autonomous projects. ATDMA, CODIT, MONET and SAINT are the more system-oriented projects, while MAVT, GIRAFE, and TSUNAMI focus on element or subsystem issues. Mobile Broadband System considers the more futuristic systems, covering user requirements, access, networking and integration with fixed ATM networks and terminals.

Telecommunications Information Networking Architecture (TINA) is a set of concepts for future telecommunications software development, and PLAtform for TINA Prototyping (PLATyPus) is an implementation of TINA carried out by Telstra of Australia. The PLATyPus project has chosen ANSAware as the Distributed Processing Environment (DPE) and has developed a number of tools for highly abstract prototype software development, and for managing the objects and blocks in the DPE. These tools have been used to implement a Universal Personal Telecommunication Service as an illustration.

Communications software -- Evaluation
Improvement of communications software technology is essential to provide dependable, quality and customer-oriented applications that are quick and economical. A 'visual' approach, involving the use of graphics, icons, symbols and color has been adopted by telecommunications software programmers. Rapid prototyping techniques allow the use of specific models of complex telecommunications software. Object-oriented techniques are also being used as they help create economical, versatile and easily maintainable systems. Workstations provide a favorable environment for the development of communications software.

Motorola Inc., extended its integrated hardware and software embedded computing solutions with the announcement of its first Application-Enabling Platform built on the Advanced Telecom Computing Architecture. The new AXP Basic Integrated Platform is designed to speed time to market and lower both manufacturing and life cycle costs for telecom equipment manufacturers. The new platform enables them to simplify and accelerate many of the tasks associated with building and deploying their next-generation products. By eliminating the integration tasks required with the building-block approach to development, equipment manufacturers can focus on the core competencies that set them apart from the competition. The AXP Basic Integrated Platform is a pre-integrated and validated solution with an operating environment.
