Millimeter Wave MIMO Systems for 5G Access Networks

By | October 14, 2014

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… Read More »

SON Load Balancing and the Success of Disruptive Ideas

By | August 19, 2013

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… Read More »
