3G Wireless Communications for Mobile Robotic Tele-Ultrasonography Systems
ABSTRACT
Mobile healthcare (m-health) is a newparadigm that brings together the evolution ofemerging wireless communications and networktechnologies with the concept of ‘connectedhealthcare’ anytime and anywhere. In this article,we present the performance analysis of anend-to-end mObile Tele-Echography using anultra-Light rObot (OTELO), over the third-generation(3G) mobile communications network.The experimental setup of the OTELO systemover a 3G con ....etc

RESOURCE ALLOCATION IN OFDMA WIRELESS COMMUNICATIONS SYSTEMS SUPPORTING MULTIMEDIA SERVICES- NETWORKING

We design a resource allocation algorithm for down-link of orthogonal frequency division multiple access (OFDMA) systems supporting real-time (RT) and best-effort (BE) services simultaneously over a time-varying wireless channel. The proposed algorithm aims at maximizing system throughput while satisfying quality of service (QoS) requirements of the RT and BE services. We take two kinds of QoS requirements into account. One is the require ....etc

The communication needs of Earth observation satellites is steadily increasing. Within a few
years, the data rate of such satellites will exceed 1 Gbps, the angular resolution of sensors will be
less than 1 μrad, and the memory size of onboard data recorders will be beyond 1 Tbytes.
Compared to radio frequency links, optical communications in space offer various advantages
such as smaller and lighter equipment, higher data rates, limited risk of interference with other
communications systems, and the effective use of freque ....etc

We offer you the best underwater inspection systems. The devices are green environmental protection product due to it will cause no radiation. And it is mainly used for underwater monitor, underwater reconnaissance, hydropower station, industry observation, ground water and exploration. Due to the setting of the underwater camera, it can also be used to examine the underwater holes, underwater operation and fishing ect. So you can enjoy underwater fun at any time.

Underwater wireless communications can enable
many scientific, environmental, commercial,
safety, and military applications. Wireless signal
transmission is also crucial to remotely control
instruments in ocean observatories and to enable
coordination of swarms of autonomous underwater
vehicles and robots, which will play the role
of mobile nodes in future ocean observation networks
by virtue of their flexibility and reconfigurability.
To make underwater applications
viable, efficient communication protocols among
underwater devices, ....etc

Abstract:
Laser communication links in space are attractive alternatives to present-day microwave links. This tutorial
describes the basic concept and the functions of an optical terminal on board a spacecraft. It points out the differences
between free-space optical links on one hand and glass fiber systems and microwave directional links on the other
hand. The requirements on data transmitters and receivers as well as on optical antennas and pointing, acquisition and
tracking mechanisms are discussed. Typical application scenari ....etc
