E-Lins MIMO dual sim 4g router

MIMO technology is to improve communication quality by using multiple transmitting antennas and receiving antennas at the transmitting end and the receiving end respectively, so that signals are transmitted and received by multiple antennas at the transmitting end and receiving end.

MIMO technology key points:

What is MIMO?

In fact, multiple antennas simultaneously send and receive signals, doubling the amount of information transmission in the same frequency domain and time domain without changing the spectrum resources and antenna transmitting power. It can improve the transmission rate and reduce the bit error rate.

Process Description:

After space - time coding, the data is divided into N data substreams. The content of the N data substreams can be different. The data substreams are transmitted from N antennas, which are transmitted at the same time and occupy the same transmission channel without increasing the bandwidth. Then, it is received by M receiving antennas through space transmission, and then decoded in space to restore the signal.

MIMO advantages?

Improve transmission rate and reduce bit error rate.

MIMO faults:

With the increase of the number of antennas used, the complexity of MIMO technology is greatly increased, which limits the number of antennas used, and can not give full play to the advantages of MIMO technology. At present, only 4 antennas can be realized at the transmitting end and 2 antennas at the receiving end.

How to reduce the algorithm complexity and implementation complexity of MIMO technology on the basis of ensuring certain system performance has become a great challenge faced by the industry.
