Description
DAS Training , Distributed Antenna System (DAS ) training course covers the concepts behind network of spatially separated antenna nodes connected to a common source via transport medium that provides wireless service within a geographic area or structure. TONEX's DAS Training Course is a comprehensive technical course that covers the fundamental concepts, recent advances and open issues of the DAS.
DAS training course explored with various key challenges in diverse scenarios, including architecture, capacity, connectivity, scalability, medium access control, scheduling, security, dynamic channel assignment and cross-layer optimization.
The primary focus of this course is the introduction of concepts, effective protocols, system integration, performance analysis techniques, simulations and experiments, and more importantly, future research directions in the DAS.
