A simple solution that works quickly when the Wi-Fi radio wave does not reach

If the radio wave does not reach, the speed of Wi-Fi cannot be used.To fly the radio waves far away ...

The radio waves of the Wi-Fi router are weakened as they are separated, further attenuated by obstacles such as walls.If the radio wave does not reach, the speed of Wi-Fi cannot be used.The relay machine is the easiest solution to fly radio waves far away.As the name implies, the relay machine brides the radio waves from the Wi-Fi router and deliver it to the slave unit.The attraction is ease of introduction.The router SSID and encryption key are copied to the relay machine, and the slave unit is connected to the stronger radio wave, so you do not need to change the existing network environment.Most relay machines can be set automatically and there is no need to match the manufacturer.[Visual explanation] Immediate action solution when Wi-Fi does not reach

■ The location of the relay machine is also important

When using a relay machine, consider the most effective installation location.Since the relay machine only sends the received data as it is, it is essential that the connection with the router is stable.If you attenge here, no matter how good the broadcast machine and the slave unit have good radio waves, the lost data cannot be restored.By the way, there are some products that Wi-Fi router itself operates as a relay machine.

■ Pay attention to the "mesh" of the radio waves

The weak point is that the relay machine cannot handle reception and transmission at the same time in the same frequency band. When reception and transmission are executed with each other, the transmission speed is substantially half. Therefore, there is a function that can perform reception and transmission simultaneously in each of the 5GHz band and 2.4GHz band. Although the name is different for each manufacturer, it is called "dual band simultaneous connection". Recent relay machines are increasingly compatible with "mesh networks". This is a technology that extends radio waves like a net eye, and compatible products can act on some of the Wi-Fi routers, improving the communication speed and expanding the communication range. However, the price is higher than the normal relay machine, and it is difficult to prepare in the same series of the same manufacturer. However, recently, products that have adopted a standard called "Easy Mesh", which exceeds the barriers of manufacturers, have begun to appear.
