Description
Technical Field
The invention relates to the technical field of WiFi signal enhancement, in particular to a novel antenna for enhancing a WIFI signal of a router.
Background
Although today's wireless network technology is ubiquitous in our lives, wifi technology is relatively less mature. The first "wireless network" appeared in the 70's of the 20 th century, but wireless WIFI technology has not become powerful enough and inexpensive to walk into thousands of households until the last few decades.
The wireless wifi technology is delicate, and has great limitation due to the limitation of the working principle. All wifi wireless signal networks use wireless radio frequency transmission, just like the radio and wireless television in the past. While wireless wifi uses signals at frequencies between those of natural microwaves and radio stations.
If your wireless router is broadcasting with radio waves, the signal may collide with other types of radio signals. Thus, other forms of radio technology suffer from the same problems as your home wireless network signal attenuation or range reduction: obstacles that affect signal strength, interference from other radios, older low power radios, receiving device technology, etc. issues may cause the network signal to be weak. Radio frequency wireless network standards are established in accordance with the Institute of Electrical and Electronics Engineers (IEEE). Most of the current home routers operate in the 2.4GHz or 5GHz band.
Typically, many wireless devices are installed in a home. That is, there may be many devices in the home that are transmitting interfering signals. If the transmitting frequency of any equipment is the same as that of the wireless router, a signal interference phenomenon occurs; your wireless signal may be being interfered with by other devices, if: 1. even if you are stationary in place, your wireless device shows low signal strength and is good and bad; 2. when connected to WiFi, access to the internet is slow. File transfer rates can also be affected; 3. bluetooth device matching is difficult; 4. the internet is often disconnected. The wireless signal may be weakened by interference with signals of other electrical devices. All of the following devices may interfere with the wireless wifi signal: refrigerator, television, microwave, power cord, remote control, wireless audio device (audio, microphone), display, monitor, wireless camera, bluetooth cell phone, satellite tv receiving pan, etc.
The traditional solution to the interference of the wireless device to the WiFi signal is: other devices that may cause interference are shut down one by one. After each device is shut down, the device is checked for changes in signal strength or signal range to find the most severe device to shut down. Such investigation is time-consuming and laborious, and to the present situation that present intelligent house is popularized, wireless equipment in the house only can increase but not reduce, and the interference condition is more serious, and to some important wireless equipment that send stronger interference signal, blind closing can only go against with advanced intelligent life theory.
