This paper describes a smart radio network that can facilitate communication of radios operating under congested conditions in the 2.4 GHz unlicensed band. The network detects legacy systems spectrally, temporally, and spatially, and implements a novel avoidance technique to reduce or remove interference with the legacy systems. The system was designed by a team of students from Carnegie Mellon...

This paper presents the design and successful implementation of a local area network bridge based on the link layer AX.25 packet radio protocol and the AppleTalk Personal Network on the Macintosh computer. Opera&d as a duplex communication channel between interconnected networks of computers, the packet radio system provides the transmission of the network layer data packets. A working prototyp...

Cognitive radio (CR) is an emerging technology that enables the flexible development and deployment of highly adaptive radios that are built upon software defined radio technology. These types of networks have applications in dynamic spectrum access, co-existence of different wireless network, interference management, etc. They are touted to drive the next generation of devices, protocol and ap...

Radio wave propagation models are extremely important in radio network planning, design as well as in interference planning. Radio propagation is essential for emerging technologies with appropriate design, deployment and management strategies for any wireless network. It is heavily site specific and can vary significantly depending on terrain, frequency of operation, velocity of mobile termina...

Cloud radio access network (C-RAN) becomes a promising scenario to accommodate high-performance services with ubiquitous user coverage and real-time cloud computing in 5G area. However, the radio network, optical network and processing unit cloud have been decoupled from each other, so that their resources are controlled independently. Traditional architecture cannot implement the resource opti...

Software Definable Radio Networks (SDRN) is proposed to realize a universal platform for various types of wireless services under the multi air interferences coexistence in ubiquitous networks. The SDRN is configured with universal radio base stations, radio on fiber networks, and software definable radio gateway that connects to global IP networks. This paper describes the concept of the SDRN,...

In recent years, the concept of the software radio has been put forward by the international communication society. It is well known that software radio will play an important role in third generation wireless communication systems. But until now there is not an acceptable concept of software radio. How to make software radio be applicable authentically, and how to develop its ascendancy? This ...

The present work aims is to propose a solution for automating updates (MAJ) of the radio parameters ATOLL database from OSS NetAct using Parsing. Indeed, this will be operated by RAN (Radio Access Network) service mobile operators, which ensures planning and optimization network coverage. overall objective study make synchronous physical data sites deployed in field with contains all coverage n...
