mmWave: Battle of the Bands
Every year the number of wireless enabled devices and the amount of data consumed continues to grow at an exponential rate (53% CAGR.) As these devices create and consume growing amounts of data, the wireless communications infrastructure that connects these devices must evolve to support the demand. Increasing the spectral efficiency of 4G-based network is not enough to deliver the step function in data rate necessary for the three high level 5G use cases as defined by 3GPP, shown in Figure 1, with the goal of providing ubiquitous, instantaneous mobile broadband data. Recognizing this, researchers have been looking to higher frequencies as a potential solution. Positive results from early channel sounding work is refocusing the world’s wireless standardization bodies on how next generation 5G wireless systems might incorporate and benefit from these new frequencies and wider bandwidths.
