Learn about seamless Wi-Fi roaming solution in minutes

Case 1, a large house need a Wi-Fi seamless roaming signal coverage solution.

  “I live in a quite large house. It’s on four floors, and it has thick walls; having a reliable Wi-Fi connection everywhere is a struggle.
  At the moment, I’m using several independent routers, each one with its own SSID and connected to the WAN network. This solution works fine as long as I’m standing still in one point, but as soon as I walk away from the router I start getting problems. Indeed my devices stay connected to a router until the connection drops, and only then they connect to the next router, causing a few seconds gap.
  An alternative setup to mine would be using the same SSID, encryption and password for all the routers, so that my devices only see one network. The problem with this setup is essentially the same of the first one: even tho the devices only see one network, there are several different routers; so they tend to stay connected to one router until the connection drops, and then they switch to a better one, still causing a gap.
  I think the best solution would be routers that “talk” to each other and handle the network switching by themselves, generating a single whole network so that it appears that only one router exists, and the devices keep transferring data seamlessly while moving from one point to another.
  I think that’s what the WiFi routers do. eeros talk to each other wirelessly, but I wouldn’t mind wiring my routers together.

  Does such a solution exist for “normal” routers? How should I set them up? Should I just buy some WiFi routers? Or should I just bear with my current setup?”


What is seamless wifi roaming solution? How about WiFi APs configuration?

  Wireless AP Configuration Planning (wireless devices automatically wireless roaming between multiple APs)
  Wireless roaming wireless AP configuration and wireless AP configuration is basically the same, but should pay attention to the following aspects:
  All wireless APs must use the same SSID.
  All wireless APs must use the IP address of the same network segment and be in the same VLAN.
  Wireless APs with overlapping signals can not use the same channel.
  Because multiple AP signal coverage areas overlap each other, the channels occupied by each AP coverage area must comply with certain specifications and the adjacent same channels can not be covered with each other. That is, the wireless APs in the mutual coverage areas can not adopt The same channel, otherwise, will cause AP interference in the signal transmission, thereby reducing the AP’s work efficiency. Of the 11 available channels, only 3 are completely uncovered. They are channel 1, channel 6 and channel 11, respectively. Using these channels as multi-cellular coverage is most appropriate. In addition, the wireless AP used to implement the wireless roaming network must use the same network name (SSID) and use the IP address of the same network segment. Otherwise, the wireless client can not implement the roaming function.
  Wireless roaming network, the client’s configuration and access point network configuration exactly the same. Users in the mobile process, simply can not switch between wireless AP.

Case 2, hotel’s wireless roaming solution

  “Our WiFi will only appear single name, and no matter where you move to, signal will not be broken, your equipment will automatically connect to a “same” WiFi. Such as a hotel WiFi coverage solution.”
  After you enter the WiFi password in the lobby of the hotel, connecting WiFi, no matter where you go, as long as there is a signal from our WiFi device, no need manually re-enter password and connect to a WiFi again, we call this feature is – WiFi seamless roaming.

Pay attention to the technical knowledge while building wireless roaming solution between multiple APs

 When setting up a wireless roaming network, you need to pay attention to the following points:
  1. AP signal coverage areas should overlap each other, otherwise it will lead to wireless network blind area. In other words, the distance between wireless APs should be less than the limited transmission distance of wireless APs. The wireless APs covered by each other must use different or even non-adjacent channels. Otherwise, serious interference will be caused and the AP communication efficiency will be reduced. Channel is the frequency band, IEEE 802.11b / g is working at 2400 ~ 2 483MHz, the United States can be divided into 11 standard channels (channel), the European standard can be divided into 13, the Japanese standard can be divided into 14, a difference of 11MHz between each channel . If channel1 is 2 412MHz, channel2 is 2 423MHz, and so on. In fact, there is absolutely no interference between channels 1, 6 and 11.
  2. The wireless AP must be set to the same SSID. Different SSID means different wireless networks, and can not achieve wireless roaming. Note that the SSID is case sensitive. You must use the same WEP or WPA encryption. All wireless APs and clients must use the same WEP or WPA encryption or they will not be able to establish a connection with each other. WEP and WPA are also case sensitive.
  3. wireless AP and wireless client must be in the same VLAN, the same IP address segment.


Seamless roaming benefits


  Intuitively switches your device to the strongest Wi-Fi network


  Ensures connection when roaming in and outside of y0our home without dropping a Wi-Fi signal.


  Eliminate the need to switch between networks. The router terminals have one network name or SSID.

Easy configuration
