An investigation into the downlink Web traffic capacity of W-CDMA land mobile satellite communication systems for Geostationary (GEO) and Medium Earth Orbit (MEO) constellations is presented. It is shown that the effect of power control errors on the Web traffic capacity severely degrades the performance of mobile satellite systems. It is also shown that the use of the proposed macrodiversity system is to mitigate the effect of power control errors, and consequently increases the Web traffic capacity of multi-beam GEO and MEO mobile satellite systems 相似文献

Private land mobile communications have experienced significant demand for increased capacity and for new services, but congestion within the currently allocated 450 and 800 MHz bands has severely limited the capability of present generation systems to meet this demand. This paper proposes a narrowband integrated voice/data mobile radio system which triples current voice traffic capacity and simultaneously provides capacity for mobile data communications such as mobile data terminals, automatic vehicle location, and mobile facsimile by utilizing the silence gaps inherent in speech. The system is designed to fit within the narrowband 25 kHz channels in the 450 and 800 MHz frequency bands, and thus the system can replace existing private land mobile radio systems with minimum impact. The centerpiece of the system design is an evolutionary multiplexing and access control technique known as Packetized Data, Voice Dedicated (PDVD) Burst Switching which allows transmission of data within the silence gaps inherent in speech. Simulation results for various voice and data traffic loads show the flexibility and efficiency of the proposed narrowband integrated voice/data mobile radio system 相似文献

Sensors carried by moving objects in the cities can be used in various applications such as environmental monitoring, traffic
control and recreational purposes. A mobile sensor network can be formed by sensors carried by people or buses. In this paper,
we will present a mobile sensor network programming system (MSNPS) that can program or reprogram such mobile sensor networks.
The programming process is usually initiated by a user from the Internet. MSNPS uses a gateway protocol to bridge the Internet
and sensor network, so that control and data messages can be exchanged between these two networks. MSNPS sends the program
data to the targeted sensor platforms using a tree structure formed by control messages. We developed a prototype implementation,
and analyzed MSNPS system performance. We also simulated the system in a mobile sensor network. 相似文献
