This paper reviews different wireless enterprise architecture standards to enable public safety voice communication interoperability using two-way radio. Different consoles and other means of third party between receiver and transmitter were used. The paper makes individual brief study to those solutions to compare between then, their optimal working areas and tabulates the results.
the wireless sensor network technology emerged in the late 1990s, since then it has spread across a wide range of potential applications to industry, science, transportation, civil infrastructure, and security. Main research efforts in the wireless sensor network field focused on achieving the desired performance requirements and reducing the energy consumption to the least possible. This survey paper...
Femtocell is a small sized indoor basestation to increase the coverage and capacity. Femtocell is connected through broadband backhual to the IEEE1588 to synchronize and manage the network. Due to limited/poor connectivity femtocell suffers by frequency misallignment and clock differencs. To overcome this problem MS-Assisted Receiver-Receiver Time Synchronization Strategy has been proposed. But this...
Due to the transition to digital TV (DTV); recently, many countries allow TV white spaces to be used by unlicensed devices. TV White Spaces is considered as an important step towards providing broadband access to millions of digital dividend household around the world and enabling a wide range of innovative wireless devices and services. The key challenge of TV white space systems is to have capabilities...
Multi-band antennas are very important in many application systems such as mobile phone jammer. A new shape triple-band microstrip antenna is proposed in this paper. By embedding h-shaped slots placed in the centre of a microstrip patch, the triple-band character can be achieved. Procedures to select the length and location of the h-shaped slots were discussed in detail. The required antenna gain,...
