A critical challenge facing 4G LTE fixed wireless operators is how to cost-effectively increase site capacity. Although there are many options available, including Massive MIMO, sectorization is one of the most cost effective, expedient and practical means of doubling site capacity.
Most LTE base station sites are deployed with the traditional 3-sector configuration. Not all of these sites require the significant added capacity offered by Massive MIMO solutions nor can they afford the higher prices and added weight that come with Massive MIMO.
