The true transmission distance of wireless router

The concept of wireless router transmission distance is relatively vague, although in the wireless router's product specifications are generally marked with wireless router wireless network signal effective transmission distance of 100-300 meters, of which the different transmit power of the wireless router transmission distance has a certain gap. So many friends mistakenly believe that as long as the wireless router in this effective range can receive signals, leading to the fact that is not the case.

In fact, we may have overlooked a problem, because the router products in the wireless signal transmission distance is in the ideal situation can be achieved distance, the so-called ideal state is to a router as the center, four weeks without any obstacles, and no interference can reach the maximum distance. But this is not the case, because the effective distance of the wireless router depends on the wireless transmission power of your router and network card and the number of important obstacles. According to the wireless router how to set the password wireless router security settings depth Analysis IEEE802.11 Standard, the general wireless router can cover the maximum distance is usually 100 meters-300 meters, but the scope of coverage should be mainly depending on the environment is open or not, in the case of equipment without external antenna, About 300 m in the field of vision, or in a partially open space, or in an area with an isolated object, the transmission is about 35~50 meters. If the use of external antennas (do link), the transmission distance can reach 30~50 kilometer or even farther, depending on the antenna itself gain. Therefore, it needs to be applied according to the needs of the users. So after testing we found that many times wireless router wireless signal distance transmission generally around 20-30 meters, the reason is because of buildings, objects, and signal interference makes effective distance to small speed instability, and these reasons there are many voltage instability and electromagnetic interference and other factors. Of course, there are transmission stability and distance far, are generally high-end routers. You choose the router according to your distance and the building.

Small compilation Summary: For wireless router wireless signal transmission distance we must according to the actual situation to judge, if in the relatively open place, generally no line from the signal can reach about 50 meters, or even farther, but if there are multiple obstacles in the middle, and the gap, transmission distance is only to a 10来 meters distance, Signal attenuation and obstacles have a great relationship, there are steel reinforced cement block distance is very serious generally only 20 meters, if the metal house in a shorter, so users should be based on their actual choice, for users who do not recommend wired network, or serial wireless router to achieve results.
