Remote Laboratory

By definition, a remote laboratory is the use of telecommunication to remotely conduct laboratory experiments with real measuring devices and real objects of investigation. Remote laboratory allows users to send control commands which can be pre-processed in order to prevent damage to real expensive equipment, to execute experiments in a real laboratory, and then collect …

5G in Malaysia: Progress and Challenges (Part II)

In previous article, the technical challenge/obstacle concerning the coexistence with incumbent services was mentioned. The 3.5GHz band (C-band) identified for 5G network is currently utilized by Malaysia East Asia Satellite (MEASAT) for their operational satellites, of which installation and testing of equipment for a satellite control station is set on Langkawi Island. MEASAT-3, MEASAT-3a, and …

Designing Matched Bandstop Filter for Very High Frequency (VHF) Band

A high-performance filter is always desired for wireless communication systems and applications. However, its performance is limited by the technology used to realize the filter due to the inevitable losses inherited from each technology. For instance, microstrip filters experience higher loss compared to coaxial or waveguide types which have higher inherent quality factor (Q-factor) up …

The Challenge of Using SCPI Commands

In my previous article, I introduced SCPI commands and their applications. The original idea of SCPI is to specify a common syntax, command structure, and data formats to be used by all test and measurement instruments. It does so by introducing many subsystem keywords for interfacing such as SYSTem and CONFigure. These intermediatory keywords helps the developers …

How Does RF Filters Look Like? Part II

In the last article we discuss and show the practical implementation of RF filter in mobile phone application. It demonstrated how filter technologies emerged from SAW to BAW following the evolution of mobile generation and the ever increasing demand for device miniaturization. Similar to the network infrastructure which works as the brain of the mobile …
