About the choice of wireless AP, it is enough to read this article

With the development of network technology, wireless technology and wireless network are becoming more and more mature, and the application of wireless network is gradually popularized. There are also various wireless network products, such as wireless APs, wireless routers, switches, wireless bridges, and so on..., a variety of different products meet the network needs of different scenarios, but many netizens feel that wireless network products Confused, today we will talk about what role wireless AP plays in connecting the network, what is the difference between wireless AP and wireless routing?

First of all, in terms of functions, wireless routing has NAT address translation (allowing multiple people to share the Internet) and DHCP (automatically assigning IP addresses to terminal devices), and most wireless APs do not have the above two functions, namely: wireless APs are equivalent to wireless switches, Can not be placed at the exit of the network instead of routing, but the wireless AP supports PoE power supply, which reduces the complexity of heavy power construction. At the same time, the wireless AP supports centralized management, which can upgrade, restart, modify the password and SSID of the AP in batches. In projects with a large number of APs, the advantages are more obvious.

The positioning of the two products is also different. The key lies in the number of wireless clients carried. Generally, wireless APs are oriented to the enterprise and unit market. The number of wireless clients that can be carried is 30 or more. Due to the use of higher performance The hardware configuration, whether it is forwarding performance or stability, is stronger than the wireless router. The wireless router of a few hundred yuan is family-oriented. Generally, the number of wireless clients (laptops, mobile phones, pads, etc.) that can be carried by household wireless routers is about 10. When the number of terminals continues to increase, the network speed is slow, and frequent disconnections, etc. Problems will follow one after another, which is why the seemingly inconspicuous wireless AP is more expensive than wireless routing.

Fengrunda RD-W268AP full Gigabit dual network port design, Gigabit WLAN with Gigabit LAN, 2.4GHz and 5GHz concurrent, wireless rate up to 1200Mbps. Equipped with Qualcomm's main control chip, super large 128MB running memory; including 5G priority, weak signal T division, VMM parameter optimization, intelligent flow control and many other black technologies. According to the data of Fengrunda Test Center, RD-W268AP can meet 120 terminal devices to access and run smoothly. ‍

At the same time, in the actual construction of wireless APs and wireless routers, in order to control costs, it is very common to use wireless routers as wireless APs. A large number of wireless routers deployed in the network have hidden hidden dangers for the network in later use. The first is the DHCP conflict. The wireless router has the DHCP function. When the wireless router is cascaded up with the Lan port, the DHCP function of this wireless router will conflict with the DHCP function of the egress router. Problem, because the DHCP function of the wireless router is enabled by default, once the wireless router is initialized, conflicts will occur. When a large number of wireless routers are deployed, it is more difficult to locate the fault location. The second is the network loop. There are no less than 4 Lan ports in the wireless router. When the network cables connected from the wall panels in two different locations are mistakenly inserted into the Lan ports of the wireless router at the same time, a network loop is formed. At this time, the entire network is flooded with a large number of useless data packets looped back, and the network is in danger of being disconnected. Most wireless APs have only one interface, reducing the risk of loops.

Therefore, compared to wireless routing, wireless APs have simple deployment, plug and play; simple functions, reduce the probability of conflicts, loops and other failures; high hardware configuration and strong stability; support PoE power supply, reduce construction difficulty; support AC Centralized management, strong ease of use and other characteristics, more applicable to a wide range of use, equipment and other environmental requirements. ‍
