Introduction to the application of the Wireless Distributed System in relay Mode

In wireless networks, especially in large wireless networks, the choice of mode is very important. Many networks will choose the unlimited intermediary mode. In this mode, we often use it with a wireless distributed system. So what is a wireless distributed system? Let's take a look at this article.

The wireless relay mode can achieve signal relay and amplification, thus extending the coverage of the wireless network. The central AP supports up to four remote wireless relay AP access modes. The wireless relay mode of the Wireless Distributed System (WDS) provides a new wireless networking mode. It is applicable to scenarios with open spaces that are not easy to lay ethernet cables, such as large open office areas, warehouses, and docks.

What is WDS?

To put it simply, the wireless relay mode of the Wireless Distributed System (WDS) enables the Wireless AP to communicate and relay between wireless APS on WDS ), this does not affect the Wireless AP coverage function.

The wireless distribution system (WDS) creates a link between two AP devices through a radio interface. This link can relay the traffic from an AP that does not have an Ethernet connection to another AP with an Ethernet connection. WDS allows you to configure up to four point-to-point links between access points.

Note that not all APs support WDS, which can be viewed clearly during the purchase. It also describes the transmit power and antenna gain parameters when purchasing products. The unit of AP transmitting power is dbm, and the unit of antenna gain is dbi. The higher the two values, the stronger the signal penetrating power of wireless devices. The transmit power of a Common AP is below 20 dBm, and the gain of the antenna is between 2 and 2 ~ Within the 3dbi range, according to experience, the 2dbi gain antenna signal can penetrate two walls. There is also a shared network. The entire WDS is equivalent to a large network. The more users, the lower the bandwidth each user receives. It is best to buy a uniform brand of wireless devices, select the bandwidth device based on the actual situation.

Application Advantages of Wireless Distributed System (WDS)

The wireless hybrid mode of the Wireless Distributed System (WDS) Supports Wireless Access Points (APS) in point-to-point, point-to-point, and relay application modes, working in both modes. That is, the Bridge Mode + AP mode.

The innovative wireless distributed system (WDS) in the wireless LAN has changed the original single and simple wireless application model. For example, when you select a wireless WDS solution for large hotspot areas and enterprise users, you can connect to each AP through various optional wireless application methods, this greatly improves the flexibility and convenience of the entire network structure. It is particularly worth mentioning that wireless network users can purchase at least wireless devices to achieve more functions.

WDS function settings

For each AP to be included in the wireless distribution system, follow these steps.

1. Click Configure configuration)> Interfaces interface ).

2. Check that the AutoChannelSelect automatic channel is selected.) disabled ).

Write down the MACAddressMAC address of the radio device to be included in the wireless distribution system ).

Scroll down to the WirelessDistributionSystem wireless distribution system) title.

3. Click Edit to update the WDS table.

4. In the WirelessDistributionSetup wireless distribution settings) dialog box, enter the MAC address of the PartnerMACAddress partner.

5. Set the Status of the device to Enable ).

6. Click OK to restart the AP.

So far, WDS settings are complete.

Precautions for WDS

Each wireless distribution system (WDS) link is mapped to a logical WDS port on the AP. The behavior of the WDS port is similar to the Ethernet port, rather than the standard wireless interface: On the BSS port, the access point is learned through pass and frame, while on the WDS or Ethernet port, access Points are learned only through frames. Note the following when setting WDS:

The WDS link shares the communication bandwidth with the client. Therefore, although the maximum data rate of the Access Point Unit is still 11 Gb/s/Second, the client throughput will decrease when the WDS link is active.

If no partner MAC address is configured in the WDS table, the WDS port is disabled.

Each WDS port on a single AP should have a unique partner MAC address. Do not enter the same MAC address in the WDS port list of the AP.

Each access point of a WDS member must have the same channel settings to communicate with each other.

Each access point of a WDS member must have the same WEP encryption settings. WDS does not use 802.1x. Therefore, to encrypt the WDS link, you must configure WEP encryption for each access point only in WEP encryption or hybrid mode ), each access point must have the same encryption key 1.

If the network does not support spanning trees, be careful not to form a network loop between APs. For example, creating a WDS link between two access points connected to the same Ethernet will form a network loop if the Spanning Tree is disabled ).

You must disable automatic channel selection to create WDS.

If the AP connects to the network only through the WDS link, you need to set a static IP address to manage the AP through the Web interface.
