Device and method for choosing transmission path in wireless network

Abstract

The invention relates to a device for choosing a transmission path in a wireless network, comprising a radio frequency module, a fundamental frequency module and a control module. The radio frequency module is coupled with multiple antennas and is used for processing packets respectively received by the antennas. The fundamental frequency module generates signal strength corresponding to the antennas according to the packets received by each antenna. The control module is coupled with the fundamental frequency module for receiving signal strength and respectively controls the antennas to be either enabled or disabled according to signal strength difference.

Description

Technical field [0001] The invention relates to a wireless network, in particular to a transmission path selection device and method in the wireless network. Background technique [0002] In a wireless network (wireless network) system, having multiple transceiver antennas can bring many benefits, such as increasing reception stability and improving data throughput (TP). Therefore, the multi-input multi-output (MIMO) technology composed of multiple antennas has been widely used in wireless network systems. [0003] Under the multiple input and output mechanism, the signal strength (SS) difference between multiple transmitting and receiving antennas is likely to be too large, such as: [0004] In the first example, in a wireless network, because the signal is transmitted in the air, the signal transmission is easily affected by the wireless channel, such as: multipath (multipath), attenuation (fading), mobility (mobility), etc., may cause The signal strengths received by multiple tr...

AI Technical Summary

Problems solved by technology

[0004] The first example, in a wireless network, since the signal is transmitted in the air, the transmission of the signal is easily affected by the wireless channel, such as: multipath (multipath), fading (fading), mobility, etc., may cause Signal strengths received by multiple transceiver antennas are different from each other

[0005] In the second example, the conditions of the antenna module itself are different. For example, different antennas are used for different receiving paths, resulting in differences in the gain value of the antenna itself.

[0006] When the signal strength between the antennas is different (for example: the difference is too large), not only the benefits brought by multiple antennas cannot be obtained, but also because the signal strength of one antenna is too low, the receiving ability of other antennas will be affected, resulting in Overall data throughput is reduced
