Non-Line-of-Sight (NLOS) operation refers to a mode of communication or sensing where the direct line of sight between the transmitter and receiver is obstructed or not available. In NLOS scenarios, the signals or waves may experience reflections, diffractions, or scatterings as they interact with obstacles such as buildings, terrain features, or other objects. NLOS operations … Read more
In telecommunications, the term “Base Switching Subsystem” is not a standard term or widely recognized phrase. However, based on the context, it appears to be a combination of terms related to mobile communication networks. It’s possible that there might be a slight misunderstanding or a combination of terms. In the context of mobile networks like … Read more
A DAS (Distributed Antenna System) is a communication system that enhances wireless network coverage and capacity by distributing antennas throughout a specific area. DAS is designed to improve the quality of wireless communication in locations where a traditional macrocellular network might face challenges, such as large buildings, stadiums, airports, or other densely populated areas.
