But there are some notable differences between wireless network radios and other radios: They send signals at a frequency of 2.4GHz or 5GHz. This frequency is much higher than the frequency used for mobile phones, walkie-talkies and televisions. The higher the frequency, the more data the signal will carry. They use 802.11 network standards, spe

In the 90, experts from many companies worked together through the International Federation of IEEE, to develop new industry standards for the mutual connectivity of new wireless products. The Wi-Fi Alliance was born from this partnership and has a worldwide development test lab that detects whether products meet availability and safety standards.

Four recommendations :
1. Upgrade your router device to a dual-band router that can support both 2.4GHz and 5GHz frequencies. It should be noted, however, that the 5GHz frequency signal has less wall-piercing capability than 2.4GHz, and that many older devices do not support this WiFi frequency.
2. Check the WiFi channel usage in the area through the Channel Viewer, then choose the mo

5. Router Location
The location of the wireless router has a great effect on the signal strength. For example, if you put a router on a concrete wall, its signal strength will be greatly compromised. If possib

Many people must have such confusion: everyone is familiar with the 2G/3G/4G communication standard, 5 G what, how to go with the WiFi pull on the relationship. The previous article explains that traditional WiFi is susceptible to interference and there are two reasons:

Non-WLAN standard devices are also using the 2.4G ISM band

2.4Ghz or 5Ghz
We can hardly find that many wireless routers are in the 5G band. So what is the wall-crossing Effect of vrouters with 5g frequencies? In fact, 2g is better at penetration than 5g. The advantage of 5g is that the transmission distance is far from 2G and more information can be transmitted. If the space is large, we recommend that you purchase dual-band routers (both 2.4G and 5g ).
