NTT DOCOMO’s antenna system to deliver wider base station coverage

21 Feb 2014

NTT DOCOMO, Japan’s leading cellco in terms of subscribers, has announced a successful field trial of an active antenna system for mobile networks, which could potentially increase the coverage range of base stations by 1.7-fold. According to a company press release, the new antenna integrates multiple antenna elements, each equipped with a small transceiver, which enables installation in confined spaces, and assures continued coverage if one or more of the transceivers fails. Further, the active antenna system’s compatibility with multiple input, multiple output (MIMO) transmission technology could help increase efficiency when deploying LTE-Advanced (LTE-A) and 5G technologies.
