I have a pretty good question which I haven’t found a direct answer to on this board.
Wireless Roaming? Is it possible.
My scenario is as the picture is shown.
First basic Setup:
SSID on all AP is the same. Encription too (WPA2/AES.. If neccesery we could implement RADIUS on MT or Windows2008)
What about frequefencies? What is best → same or differnt freq. on each AP
I have All AP connected over Lan (ETHERNET cable) to our switch and then to RB433 (WAN, HOTSPOT…).
Can I use i.e. TP-Link Wireless Routers in Access Point mode (DHCP off, Lan1 port connected to switch) or should I use MT?
Main problem iz VoIP. Will the connection break on chanching the AP?
If I use MT I can set Wireless signal Cutoff range with “Signal Strength Range”. What would be good range (-80..100?)..This will enable me to fine tune the clients to connect to the nearest AP (strongest signal)…
This scenario will be used indoors but if the results are good I could spreed it on our Outdoor APs..
Any suggestions, different approaches are welcome.
Roaming between APs does work well providing the following:
-All APs use the same SSID and encryption settings
-None of the APs are DHCP servers or perform NAT
-All of the APs just bridge the wireless customer on the WLAN to the Ethernet and all Ethernets are backhauled to a common NAT and common DHCP server.
-again - the WLAN on all APs are bridged together and all clients on the APs are on the same common IP network.
re roaming when using a wireless VoIP device - Yes it works well.
There must be overlapping coverage between your APs. If you are in a phone call using a wireless VoIP device and you leave the coverage area of an AP, there must be another AP (same SSID/network) you can roam to. This will permit you to keep the connection as you switch between APs.
Note - there might be a quick brief pause during a VoIP connection as you roam and change to another AP, but it is pretty quick and will not drop the call.
note - along the lines of what you are asking about - I am considering a project with 3,500 APs in customer homes which could permit a customer with a VoIP sip based phone to drive around town and maintain their VoIP sip phone call. The config would be a secondary SSID on all customer in-home internet accounts - the secondary SSID would not be directly for the customer homes - it would be configured only for my multi-city VoIP sip network. Almost like a cell phone company…
