The global bandwidth shortage in the wireless communication sector has motivated the study and exploration of wireless access technology known as massive Multiple-Input Multiple-Output (MIMO). Massive MIMO technology is about bringing together antennas, radios, and spectrum to enable higher capacity and speed for the super-fast 5G networks.
Massive MIMO (Multiple Input Multiple Output), short for mMIMO, is the core component of the fast-developing 5G network. It can be boiled down to one sentence: a wireless communication technology, where base stations are equipped with plenty of antenna elements and allows the transmitting and receiving of more than one data signal simultaneously.
Massive MIMO is an extension of MIMO technology, which involves using hundreds and even thousands of antennas attached to a base station to improve spectral efficiency and throughput. mMIMO multiplies the capacity of a wireless connection. It can be applied to systems with 128-1024 antennas compared to standard MIMO networks.
The mMIMO provide with these main benefits:
1. Utilizing 3D beamforming technology, and increasing capability of obtaining signal of the base station
Massive MIMO featured with hundreds or even more elements, with each steering ultra-narrow, millimeter-wave "pencil-beams" toward a receiving antenna.
2. Improving throughput and coverage
It enables more users in a given frequency band. Massive MIMO system is more sensitive to devices in high frequency bands to improve coverage. Increasing the distance and radius of cell by using of digital beamforming and coherent stumming of signals on the antenna array.
3. Strengthening the resistance to interference and intentional jamming
These thin beams minimize interference and enhance data rates.
Massive MIMO is able to serve multiple users and devices with stable and high-performed network services, enhancing the capability of network and improving the customer experience. Simultaneously, the technology in a condensed building can maintain fast data rates and consistent performance, which makes it the advanced network to address the needs of the 5G era.
To no small degree, the mastery of massive MIMO will be central to achieving the leaps in spectral efficiency that next-generation 5G wireless needs to deliver.
