There is WLNA on the mobile phone, but we usually think it is Wi-Fi. Can the two be equated?
To answer this question, we must first understand the definitions of Wi-Fi and WLNA.
(1) wireless network
Wi-Fi(WirelessFidelity) technology is a wireless network communication technology brands based on IEEE802. 1 1+0 series standards. It is the trademark of Wi-Fi alliance manufacturers, as the brand certification of products. At present, WLAN includes the following protocol standards: WAP, IEEE 802.1/a, IEEE 802.1/b, IEEE 802.1/g, IEEE 802./kloc-0.
(2)WLNA
WLNA is the full name of WLAN, which means WLAN. At present, wifi contains protocols such as IEEE802. 1 1a and IEEE 802.11b.
So in fact, WLNA contains wifi.
Tip: writing "wifi" is not recognized by the Wi-Fi alliance.
WLAN belongs to the category of WIFI, which is a network standard of WLAN. Wireless local area network is a kind of network called wireless local area network. WLAN is also a higher-level network term for WIFi.
Wireless local area network (WLAN) is a powerful Internet. A plurality of hotspots can be arranged through a local area network. For example, China Mobile EDU Campus Wireless Network is a wireless local area network, WLAN.
WiFi is a short-range wireless communication technology, which is limited by distance. It is a technical means in wireless local area network. WiFi mainly adopts 802. 1 1 b protocol. Generally, 2.4G UHF and 5G SHF ISM radio frequency bands are adopted. Wifi adopts a new technology "wireless compatibility authentication" in WALN protocol.
WLAN can be simply regarded as the function of mobile phone, which is equivalent to the wireless network card of computer. It uses radio frequency (RF) technology to transmit data and realize communication and resource sharing network system.
In addition, the coverage of WLAN is wider than that of WIFI. Usually, some railway stations, schools and squares use WLAN. After all, WiFi coverage of the Grand Plaza requires a lot of routers or wall-penetrating equipment, which is not worth the candle.
The characteristic of WiFi is that the transmission speed is fast enough to be compatible with various devices.
Some humble opinions for your reference.
Engaged in internet development for many years, welcome everyone to harass.
Our life has been deeply compressed by the wireless network. Now, if the mobile phone is not connected to the wireless network after going out, the traffic package in the mobile phone card is insufficient, and many small partners will feel isolated. Because now, whether you are reading news or sending and receiving messages, you need a network, and compared with traffic, wireless networks are obviously more casual to use. But on the network side, many friends will find that when they first start using smart phones, everyone will call the wireless network WLAN. Now, we are more accustomed to calling it WiFi. So, what's the difference between WiFi and WLAN displayed on mobile phones?
For this problem, many netizens said that they paid little attention to it, because they thought that no matter what their names were, the two networks were the same and could be used normally, so long as they did not affect their use, there was no need to worry about the difference. But what I want to tell you is that the difference between the two is very obvious, which is very useful when choosing a mobile phone!
