Abstract

The invention provides an intelligent antenna device and a method for switching radiation patterns thereof. According to the method for switching the radiation patterns thereof, the intelligent antenna device is provided with a plurality of horizontal polarized antennas and a plurality of vertical polarized antennas; a training pattern is provided; in the training pattern, more than one horizontal polarized antenna and/or more than one vertical polarized antenna is connected so as to respectively generate different radiation patterns; a plurality of training packets are sent to each connected node through different radiation patterns; according to packet error rate (PER) of the training packet and received signal strength indicator (RSSI), the radiation pattern most suitable for communication is determined, so as to provide the best connecting efficiency and quality.

Description

technical field [0001] The present invention relates to a kind of antenna and its radiation field type switching method, in particular to a kind of switchable selection of different radiation field types, and sending out training packets with various radiation field types, and according to packet error rate (PER) and signal strength (RSSI) to determine the antenna related technology of the best radiation pattern. Background technique [0002] It is generally believed that directional antennas have the advantage of power concentration, but due to their directivity, there are many transmission dead spots, which directly affect their coverage. Omni-directional antennas have fewer transmission dead spots and large coverage, but their power is relatively low. As can be seen from the above, directional antennas and omnidirectional antennas each have their advantages and disadvantages. And China Taiwan Patent No. I384686 "System and Method for a Wireless Link to a Remote Receiver"...
