Report illustrates the details of 5G mm-wave radios
Principal Analyst Joe Madden explained, “While many things about 5G are not known, industry leaders have reached broad consensus on a few architectural decisions. We’ve been able to identify the key decisions in spectrum allocation, base station deployment, and Massive MIMO array designs which will dramatically impact the basic technology for 5G. Our analysis illustrates the conditions where CMOS might be acceptable, and other conditions where SiGe, GaN, InP, or GaAs will be necessary.”
“It’s not too early for semiconductor vendors and base station OEMs to start investing in 5G. The basic construction of a radio will be radically different than 2G/3G/4G when we deploy infrastructure above 24 GHz. We’ve collected dozens of examples of hardware using wafer-scale assembly of radios to achieve Massive MIMO arrays in a compact size. We’ve met with everyone from military radar experts to commercial WiGig vendors, and we’ve identified the middle ground where each technology will play a role.”
This report looks into radio techniques that are likely to be employed. Five scenarios are considered with various spectrum allocation approaches, power levels, and array types to illustrate the design choices facing OEMs.
