MIMO technology on industrial 4g router
MIMO(multiple-input multiply-output) technology refers to the use of
Multiple transmitting antennas and receiving antennas at the transmitter
and receiver respectively, so that signals can be transmitted and
received through Multiple antennas at the transmitter and receiver,
thereby improving the communication quality. It can make full use of
space resources, achieve multiple multiple reception through multiple
antennas, without increasing spectrum resources and antenna transmission
power, can multiply the system channel capacity, showing obvious
advantages, is regarded as the next generation of mobile communication
core technology.
The so-called MIMO, literally, refers to the abbreviation of Multiple Input Multiple Output (Multiple in, Multiple out). It refers to the synchronous transmission and reception of wireless network signals through Multiple antennas, so the data transmission rate can be increased.
The correct interpretation, however, is that the network data is transmitted synchronously through multiple antennas after multiple cuts, and that the wireless signals travel different reflection or penetration paths during transmission to avoid interference, so the time to the receiving end is inconsistent. In order to avoid data inconsistencies that could not be recombined, the receiver would have multiple antennas at the same time, and then recombine the separated data using DSP recalculation, depending on the time difference, and transmit the correct and fast data stream.
Due to the transfer of data transmitted through segmentation, not only a single data flow is reduced, but higher transmission distance, and increase the scope of the antenna, so MIMO technology can not only increase both wireless spectrum data transmission speed, and no extra occupy spectrum, more importantly, also can increase the signal receiving distance. Therefore, many wireless network devices that emphasize data transmission speed and transmission distance begin to put aside the compatibility requirements of existing wi-fi alliance and adopt MIMO technology to launch wireless network products with high transmission rate.
MIMO technologies can be broadly divided into two categories: transmit/receive diversity and spatial multiplexing. Traditional multi – antennas are used to increase diversity and overcome channel fading. Signals with the same information are sent through different paths, and multiple independent fading copies of data symbols can be obtained at the receiver, so as to obtain higher reception reliability. For example, in a slow Rayleigh fading channel, one transmitting antenna and n receiving antennas are used to send signals through n different paths. If the fading between antennas is independent, the maximum diversity gain can be obtained, and the average error probability can be reduced to, and the average error probability of the single antenna fading channel is. For the transmission diversity technique, the gain of multiple paths is also used to improve the reliability of the system. In a system with m transmitting antennas and n receiving antennas, if the path gain between antenna pairs is Rayleigh fading with independent uniform distribution, the maximum diversity gain can be obtained is mn. Smart antenna technology also sends the same data through different transmitting antennas, forming an omniform beam to some users, so as to effectively improve antenna gain and reduce interference between users.
