Why need Roaming?

SEAMLESS WI-FI ROAMING • Problem

» Hotel guests want to be connected anytime and anywhere while they are in hotel, even when they are on the move

• Solution » Fast roaming between separate APs across the

hotel property allows for seamless connectivity

Purpose & Benefit • Wi-Fi users who move between the APs are able to maintain the network connection

without any human intervention » no need to manually disconnect the association to one AP and re-associate to another AP » no need to change their own IP address » no need re-authenticate under the authentication controller (ex. 4ipnet’s controller)


Roaming


PLM VLAN Roaming • It is commonly used in hospitality venues to manage

the internet service for their guest rooms and public areas

• Each Port Location Mapping entry can be configured to provide auth. required service at the location corresponding to the entry’s VLAN Tag


Layer 2 & Layer 3 Roaming • Layer 2 Roaming

» Same SSID » Same Subnet » Same Security Level » Different Channel (Optional)

• Layer 3 Roaming » Same SSID » Different Subnet


Test for Layer 2 Roaming • You may do a simple test

1. Scan for their SSID and connect 2. Go to each AP’s web UI (eg. AP-1 and AP-2) and see

which one being connected. 3. Power off the AP being connected (eg. AP-1) and you

will see you on the other AP’s current user list immediately (eg. AP-2).


Power Off

WISPr


Local/ On-Demand Account Roaming Out • Local/ On-Demand Database of WHG711 acts like an external RADIUS server for remote gateway

to service “Roaming Out” users. (AP is not enabled as 802.1X Authenticator)


Cross Gateway Roaming


• The device’s IP address does not change after the roam. • The only thing is that service zones of multiple gateways

should not be of the same subnet. Please use 172.21.1.x/24 as WHG2's default SZ, for example.

4ipnet Cross Gateway Roaming – [Configurations for controller#1 - Master mode]

1. Click Main Menu -> System -> Service Zone; Enable SZ1 (ex: 192.168.1.x/24) 2. Create a test local account (ex: user1@local) 3. Go to Main Menu > Network > Client Mobility > Cross Gateway Roaming; set controller#1 to Master Mode, enter the WAN IP address of controller#2 & the Key string, check the Active checkbox, and click Apply. [Configurations for controller#2 - Slave mode] 1. Click Main Menu -> System -> Service Zone; Enable SZ1 to be with different IP subnet from SZ1 of controller#1 (ex: 172.21.1.x/24) 2. Go to Main Menu > Network > Client Mobility > Cross Gateway Roaming; set controller#2 to Slave Mode, enter the WAN IP address of controller#1 & the Key string, and click Apply. 3. Click on the "Node List" to verify the active Roaming Gateways. [Tests of client computer] 1. Client associates to AP1 on the LAN side of controller#1 2. Log in with user1@local 3. Go to controller#1 Main Menu > Status > Online Users to check if the client is online 4. Force the client to roam to AP2 on the LAN side of controller#2; check IP address of the client - it keeps original IP address 5. Go to controller#1 Main Menu > Status > Online Users to check if the client is still online; 6. The client's Internet traffic will be sent through the GRE tunnel back to the controller#1 and then routed to the Internet through the WAN connection of the controller#1 at the Master site. Note: the service zone mapping is 1-to-1 (SZ1 to SZ1, SZ2 to SZ2, SZ3 to SZ3, etc) on both sides of master and slave controllers, and the subnet must be separate.
