Millimeter-wave frequencies between 6 and 100 GHz provide orders of magnitude larger spectrum than current cellular allocations and allow usage of large numbers of antennas for exploiting beamforming and spatial multiplexing gains. In this article, we describe the main design concepts when integrating mmWave RANs into 5G systems, considering aspects such as spectrum, architecture, and backhauling/fronthauling...
Boundary-Scan is a standard architecture of DFT (Design For Testability), and is widely applied to board test, system debug and IC program. A general design method which adds the boundary-scan architecture into the logic core of circuit is proposed. Taken the IP core of 74290 as an example, the modular design of boundary-scan architecture is described by Verilog language, and verified in the corresponding...
In the traditional structure of B/S, the date interaction between the client and the server is Request-Response mechanism based on the HTTP model Protocol so that the operating efficiency and real-time of B/S monitoring system limited greatly which are basic requirements of modern industrial production and control system. On this issue, a new B/S model industrial control system based on Ajax technology...
Due to the extremely high user density in in-flight entertainment (IFE) systems, the required sum data rate is in the order of several Gbit/s, which can not be provided by existing standard wireless systems. To achieve such high data rates, the 60 GHz frequency band is very well suited due to its specific advantages. In this paper, a design concept for a cellular-based wireless IFE system is presented...
