Currently, the most popular Wireless LAN (WLAN) operating frequency is 2.4 GHz, which belongs to the category of microwave communication. The transmission feature is linear and visible, that is, visual communication and con
.
Many users may have this question: is there any radiation in the wireless network? The answer is yes, but you can rest assured that the average output power of a wireless LAN device is less than mW. Let's make a comparison: when we call or send text messages via a mobile phone, the output power range is 600 mW, and the handheld walkie talkie may reach 5 W. Wireless LAN devices have much lower output power
Wireless technology is becoming increasingly mature, and wireless LAN has become a frequently used network device. Here we will summarize some common network faults.
When purchasing a wireless LAN, users must pay special attention to the following features to decide their own products, including: scope of coverage, transmission rate, extent affected by Multipath, degree of data integration provided, interoperability with wired infrastructure, interoperability with other wireless infrastructure,
Faults are also emerging during the use or maintenance of wireless networks. Here we will introduce you to several detailed fault instances. The following articles will explain in detail.
The operating frequency of a wireless LAN (WLAN) is generally 2.4 GHz and belongs to the category of microwave communication. The transmission feature is linear and visible, that is, visual communication and contact methods. This shows that rain, fog, walls and other obstacles can affect the transmission qualit
