Millimeter Wave MIMO Systems for 5G Access Networks

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 »

Is the Personal Cell Technology for Real?

The media is abuzz with the news of the pCell wireless technology – after all, it’s not too often that someone comes out and claims to have a technology that will change the world! For now, too little has been revealed on this technology, which is understandable for a startup.  The aura of mystery is necessary to fuel… Read More »

SON Load Balancing and the Success of Disruptive Ideas

Thirteen years ago we were working at Metawave to address the capacity challenge operators were facing (sounds familiar?). Our solution was an adaptive system that automatically adjust the antenna beamwidth to change the coverage area of a given sector according to the traffic load. By changing the antenna patterns, and consequently the coverage footprint, it is possible to… Read More »
