SDMA is the key for 5G

Spectrum resources are the most precious resources in wireless communication. Due to stratospheric traffic increases, spectrum utilization encounters technical bottlenecks with current wireless technologies. Improving spectrum efficiency has become a problem to be settled urgently.
Upgrading communication technology is like upgrading the highway (communication pipeline), in both cases you seek traffic improvement, that is more vehicles (data) within the unit time. To achieve this, the following
