How Non-Line-of-Sight Backhaul Really Works

September 12, 2012 7:19 am | by Frank Rayal, Vice President of Product Management at BliNQ Networks | Blogs | Comments

Ever wondered how non-line-of-sight (NLOS) backhaul really works? And how NLOS backhaul is different from Line-of-Sight (LOS) backhaul? I will explain the difference here and highlight some key issues that make a very big difference in the performance of NLOS systems. A fundamental practice in designing wireless systems is to understand the characteristics of the propagation channel and to design a system that takes advantage of such characteristics while mitigating for different impairments.
