Trends in Wireless Network Densification

Small Cells - Network DensificationOne of the main trends in radio access network (RAN) is the bifurcation of systems that enable network densification. Today, mobile network operators have more options than ever before for the means of providing service to their subscribers. Alongside the evolution of wireless standards to provide higher spectral efficiency, vendors have unleashed a wide variety of radio access nodes. While the macro cell remains the workhorse, small cells, distributed antenna systems (DAS), distributed radio systems (DRS) and Cloud RAN (CRAN) are systems that will see increasingly wider deployment in the future. Given this, what are some of the trends that we see in this space? Read more of this post

Free Space Optics: An Overview of Market and Technology

Free space opticsFree space optical (FSO) technology in commercial applications has been around for a couple of decades now. During this time, significant developments happened to improve the utility and reduce cost. Today’s systems pack more capacity in smaller volume and at lower price while measures to improve reliability are integrated into the solutions to increase the robustness of the link. ¬†Yet, the commercial applications of FSO remain in niche segments without a major breakthrough into mainstream markets such as mobile backhaul. In this article, I like to review the basic elements of the FSO market to shed some light on this segment of backhaul that has lived in the shadow of RF technologies. Read more of this post
