A new report by Mobile Experts predicts an industry shift away from the 3GPP roadmap, which calls for evolution to 8x8 MIMO (Multiple Input-Multiple Output) technology.
“Field testing has shown limited benefit from the simple addition of more antennas and early implementation of Multi-User MIMO” said Joe Madden, Principal Analyst at Mobile Experts. “Instead of blindly following the 3GPP evolution path, mobile operators are looking for different, creative ways to boost throughput and capacity. Interference cancellation and Cooperative Multipoint (CoMP), as well as advanced MU-MIMO will be important technologies during the next few years.”
“Mobile Experts is the only analyst firm that focuses on the radio chain for both infrastructure and device markets," Maden said. "In the case of MIMO, it is critical to examine concerns of suppliers of a huge variety of equipment, ranging from base stations and femtocells to smartphones, tablets, and PC modems. In particular, the concerns of device suppliers regarding size, battery life, and cost are crucial in the technology choices for the 2014-2016 timeframe.”
