How to understand AP isolation in wireless routing and what are the advantages of AP isolation

Many people who have installed wireless routers know that AP isolation is a routing mode. AP isolation refers to the fact that each connected device cannot communicate with each other after it is turned on, which acts as an isolation to ensure the safety of different users.

basic introduction

AP isolation, English term: AP Isolation is more common in wireless communication, and it is common in router settings. AP isolation is very similar to the VLAN (virtual local area network) of a wired network, which completely isolates all wireless client devices so that the client can only access the fixed network that the AP accesses.

Scope of application

This measure is very suitable for the construction of wireless networks in public places such as large conference rooms, hotels, airports, etc., to keep each connected wireless client isolated from each other and provide more secure access to each other. This measure does not have much practical significance for home users, but enterprise users can use this method to strengthen the security of wireless networks in some special occasions. For example, public events such as meetings attended by customers or personnel from outside units. This method is used to set up Hot Spot in public hotspots such as hotels and airports to keep connected wireless clients isolated and provide safe Internet access.

What is the meaning of AP isolation in wireless routers

To talk about AP isolation, let’s first explain what an AP is. AP is an abbreviation for access point (connection point), which is used to connect wireless clients in a wireless network. The biggest difference is that there is no NAT (Network Address Translation) function. The following editor will introduce the difference between a wireless AP and a wireless router.

In terms of appearance, the wireless AP and wireless router are really like the two brothers. They have the same appearance and both have antennas. In addition to reading the description text, you can only see the true colors of these two devices by logging in to the management interface, but because of the wireless AP In addition to the need for an Ethernet port for configuration, it does not provide many Ethernet ports like home wireless routers. This is the most obvious sign to distinguish between wireless APs and wireless routers. Let’s talk about the two devices separately. Features and differences:

From a functional point of view, wireless routers have one more NAT address translation function than wireless APs working in point-to-multipoint mode, and now common wireless routers on the market generally support WDS technology, which can connect multiple wireless routers. Together, they play a role in covering a larger wireless network range. To put it bluntly, this wireless router has all the functions of APs in point-to-point mode and point-to-multipoint mode, and at the same time can perform address translation (NAT). It is with the NAT function that the internal network address (such as can be converted into a public network address, so that multiple hosts on the internal network can share the INTERNET connection.

Summary: AP isolation is equivalent to VLANs in Ethernet. If an Ethernet switch is configured with multiple VLANs, hosts in different VLANs cannot communicate with each other under normal circumstances. If you want to communicate with each other, Need to rely on the routing table to achieve (the switch is a three-layer switch), well, a bit far away, AP isolation in a nutshell is to isolate different wireless clients, can not perform data exchange, usually used for data security requirements In a higher environment, such as in an enterprise, if a customer visits and wants to go online, AP isolation can be used to ensure data security within the enterprise.

The following editor will introduce you to several advantages of AP isolation.

1. Intelligent management equipment

The dual WAM3.75Gwireless-N broadband wireless router allows you to enjoy the extremely fast Internet life anytime and anywhere under the guarantee of WIFI security, and will never drop the line. The intelligent management is equipped with the latest 3G and Wireless-N technologies, allowing you to enjoy worry-free freely Network connection, whether in outdoor meetings, exhibitions, venues, factories, or homes. Through the USB2.0 interface, this hardware allows your desktop computers and notebooks to enjoy wired or wireless network cable networks. Easily download pictures, high-definition videos, run multimedia software, watch movies or share files with your clients, team members, friends or family.This router can even be used as a printer server, Webcam or FTP server to realize network sharing of hardware

2. Always connect online

Using a wireless router, you can connect a 3G/HSDPAUSBmodem to its built-in USB interface, which allows you to connect to networks exceeding 3.5G/HSDPA, 3.75G/HSUPA, HSPA+, UMTS, GDGE, GPRS, or GSM networks. The download rate is up to 14.4Mbps. JGR-N605 supports EthernetWAN interface and can be used as ADSL/Cable modem. When the wired network connection fails, through the JGR-N605 built-in automatic fault conversion function, you can quickly and smoothly connect to the 3G wireless network, ensuring maximum connection and minimum interference. When the wired network is restored, it can automatically connect again, reducing or minimizing connection costs. This feature is particularly suitable for office environments, where continuous network connectivity is very important.

3. Multifunctional service

The USB interface of the wireless router can be used as a multi-function server to help you build your own network. When you are out, you can use the office printer, monitor your house via Webcam, share files with colleagues or friends, and even You can download FTP or BT files. Wireless routers with a USB interface are relatively rare on the market. Among them, a router VE982W from the Flying Fish Star is a wireless router with a USB interface.

4. Multifunctional Display tool

The unique 3G management center is a multi-functional Display tool that visually displays the signal conditions, allowing users to make the most of their connections. You can monitor the bandwidth using upload speed and download speed. This tool can calculate the total amount of data used per month or the total amount of hours.

5. Gain antenna signal

In the wireless network, the antenna can achieve the purpose of enhancing the wireless signal, which can be understood as an amplifier of the wireless signal. Antennas have different radiating or receiving capabilities for different directions in space, and depending on the directivity, antennas have two types: omnidirectional and directional.
