Nowadays, the demand for wireless mobile services
is copious, and will continue increasing in the near future.
Mobile cellular operators are therefore looking at the unlicensed
spectrum as an economical supplement to augment the capacity
of their soon-to-be overloaded networks. The same unlicensed
bands are luring internet service providers, venue owners, and
authorities into autonomously setting up and managing their
high-performance private networks. In light of this exciting
future, ensuring coexistence between multiple unlicensed technologies
becomes a pivotal issue. So far this issue has been merely
addressed via inefficient sharing schemes based on intermittent
transmission. In this article, we present the fundamentals and
the main challenges behind massive MIMO unlicensed, a brandnew
approach for technology coexistence in the unlicensed bands,
which is envisioned to boost spectrum reuse for a plethora of use
cases.
