China has opened up its telecommunication equipments market for nearly two decades and many equipment manufacturers generate most of the revenues form this market. With China’s imminent entry of the World Trade Organization (WTO), the foreign investors are eager to occupy the Chinese telecommunications services market, which is currently closed to foreign investments. To find a niche in this ma...

Overview and Motivation Rapid development of the telecommunication industry progressively introduces new and enhanced functionalities into existing software systems thus increasing the system size and complexity. The software systems of telecommunication equipment become very large software systems where high reliability requirements are even harder to reach. The most common project type for de...

Antiseismic property of telecommunication equipment is very important for the grasp of the damage and the restoration after earthquake. Telecommunication business operators are regulating seismic standard for their equipments. These standards are organized to simulate the real seismic situations and usually define the minimum value of first natural frequency of the equipments or the allowable m...

Hospitals rely on pagers and ordinary telephones to reach staff members in emergency situations. New telecommunication technologies such as General Packet Radio Service (GPRS), the third generation mobile phone system Universal Mobile Telecommunications System (UMTS), and Wireless Local Area Network (WLAN) might be able to replace hospital pagers if they are electromagnetically compatible with ...

In fields such as mobile communications, video, and finance, the Precision Time Protocol (PTP) is an effective method for achieving highly accurate time synchronization. However, PTP profiles differ depending on field in which used, synchronization not possible between different profiles. Therefore, when telecommunication carriers distribute to each field, networks are required profile, resulti...

The tool OpenSESAME offers an easy-to-use modeling framework which enables realistic availability and reliability analysis of faulttolerant systems. Our symbolic engine, which is based on an extension of binary decision diagrams (BDDs), is capable of analyzing Markov reward models consisting of more than 10 system states. In this paper, we introduce a tool chain where OpenSESAME is employed for...

The first stage in the construction of an effective subsystem for monitoring technical state communication devices and navigation equipment is to analyze development modern information telecommunication systems public networks. analysis will make it possible find solutions problem improving safety. study aims develop a method device distributed based on self-contained vessel or unmanned aerial ...

In this work, we consider a method of searching of the direction of a wireless network development (the places of new access points or base stations etc.) optimized with criteria of coverage of important territories and minimum cost of equipment and additional needed infrastructure which does not need the execution of special field testings and determination of the exact geometry of elements of...
