How can I improve my signal quality? Whole-house WiFi has the solution
2024-07-29
A full signal and a fast or slow internet speed are not exactly related.
If you compare the signal to a highway, then the network speed is equivalent to the speed of traffic flow, and the network noise can be seen as the scene of a car accident. The more car accidents there are, the slower the traffic flow will be, and even a highway with ten lanes can't carry too many car accidents.
Therefore, the speed of the network in addition to the signal strength, but also associated with the signal quality, the less network noise, the better the signal quality, the faster the speed of the network naturally.
Nowadays, most families are equipped with wireless Wi-Fi, and more and more electronic devices on the market are beginning to support Wi-Fi access. In addition to traditional cell phones, televisions, cameras, and now consumers commonly used water purifiers, rice cookers, desk lamps, etc., all support Wi-Fi links. If there is no stable signal, it is easy to lead to frequent device dropouts, unstable network speed and other problems. So, how can you ensure that all devices have stable access to WiFi?
Whole house Wi-Fi (AP+AC) solution can solve this problem perfectly. In general, all the rooms signal about -75dBm just to solve the problem of having a network, although there is a signal but the transmission rate is low. Whole-house Wi-Fi, on the other hand, can make all rooms have high-quality signal, high “signal-to-noise ratio”.
So, how to improve the signal power?
As we all know, two-way communication between cell phone and wireless AP (or wireless router), there are two powers on the AP, one is the receiving power, one sending power, if you just simply improve the AP side of the sending power, will not be able to meet the requirements of two-way communication. Cell phone power at a certain level, the power of the signal passing through the wall and reaching the AP will not be significantly increased. Whole-house Wi-Fi uses an AP that can cover all rooms, there is no blockage between the wireless terminal and the AP, the signal is not attenuated by obstacles, and the effective signal power will be relatively high. With wireless terminals and APs identified, high power means that higher negotiated rates can be matched. From the perspective of signal quality, the signal and rate can also be improved by reducing the noise power. Due to limited wireless spectrum resources, the source of wireless noise is still mainly wireless co-channel and neighboring frequency interference.
In a whole-house Wi-Fi solution, in addition to the LNA (Low Noise Amplifier) technology used on the wireless AP, the wireless controller in the whole-house Wi-Fi can make a big difference.
If there is no wireless controller at home, it means that all the wireless routers installed are individually configured, and there is no connection between the routers to coordinate their work, and it is easy to have signal interference, which comes from internal signal interference on the one hand, and signal interference from the next door neighbor on the other. The wireless controller, which can play a centralized management role, its centralized management, not only to achieve the wireless signal name of the downlink function, but also adjust the channel of all APs, so that all APs work in coordination to avoid the wireless same frequency and neighboring frequency interference.
In addition, the AP also has the function of automatic power adjustment, so that all APs cover their respective areas, avoiding excessive signal overlap between them (excessive signal overlap may lead to cell phone connection to the physical distance of the AP, affecting the user experience). In addition, when a wireless AP is damaged, the surrounding APs can increase their transmit power to supplement the blind spots. It can be seen that the whole-house Wi-Fi (AP+AC) model will bring a better user experience.
