Monitoring the progress of 5G at the recent 5G Americas analyst summit, where carriers including AT&T, T-Mobile and Sprint engaged industry analyst on many 5G topics, I noted few observations. For context, the industry remains fixated on capacity: how to scale to support 11 GB in 2019 from ~4 GB monthly usage? This is fuelling the drive towards millimeter… Read More »
Guest post by Faris Alfarhan* Conventionally, millimeter wave (mmW) frequency bands have been either largely overlooked or treated solely as real estate for wireless backhaul and personal indoor networks. That is mainly due to higher atmospheric attenuation loss, penetration losses, and increased absorption and scattering in rainy conditions. However, recent measurements indicate good outdoor short range coverage –… Read More »
Free 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… Read More »
The success of personal wireless communications may have been inevitable: communications is an essential tenant of human social structure. Coupled with the proliferation of wireless communication has been a drive to open up new bands of frequency spectrum. The most recent example is the millimeter wave band around 60 GHz which was assigned for unlicensed use and is… Read More »
