Watch the video tutorial about setting up a W-AIR Multicell Network (registration is required):

...

• A maximum number of 3 cascaded Ethernet switches are supported between the primary device and secondary devices
• Only switches, which fulfil the requirements regarding Ethernet synchronization according to IEEE1588, are recommended and officially supported
• All base stations must be connected to a dedicated DECT VLAN
• The DECT VLAN must be configured to the highest priority in all the switches that are connected to the DECT infrastructure
• The backbone network load should not exceed 50 percent of the total link capacity
• The Ethernet switch must be able to use DSCP as QoS parameter

• The network must support multicast datagrams from

  IEEE1588

  Warning
  Please note

...

• that Wildix switches are EOL!  Make sure to select the switches that follow the specifications described above.

  
  

Connecting 3 Repeaters in a chain:

...

• Building Penetration: when a signal strikes on a building it is diffracted or absorbed; therefore the signal can be reduced. The amount of absorption depends on the building and its environment, the amount of solid structure
• Interference Sources: other signals can create interferences and weaken the signals of the receiving antennas. These interferences can come from the same network or from the outside. For choosing the optimal position of the Base station and Repeaters, these potential interference sources should be considered before installing a Wildix W-AIR system

• Radio/ Cell Range: a suggested distance between two base stations depends on the physical path between them. If the path loss is lessened, e.g. by minimizing the amount of walls/ obstacles on the path, then the signals of the base stations cover more distance. In a typical office building a suggested distance between two base stations is 30-40

  Warning
  Do not place base stations close to GSM Media gateways (DaySaver or W01GSM).

  
  

Capacity planning

The maximum quantity of calls is indicated in the list below:

Bad network topology: (there are more than three switches connected in a cascade)

...

• A maximum number of 3 cascaded Ethernet switches are supported between the primary device and secondary devices
• Only switches that correspond to Ethernet synchronization requirements according to IEEE1588, are supported. It is recommended to use Wildix Switches
• All base stations must be connected to a dedicated DECT VLAN. DECT VLAN must be configured to the highest priority in all the switches that are connected to the DECT infrastructure
• The backbone network load should not exceed 50 percent of the total link capacity
• The Ethernet switch must be able to use DSCP as QoS parameter
• The network must support multicast datagrams from IEEE1588

You can assign W-AIR handset to a user via the handset itself or via WMS (starting from WMS 5.04.20220309.1).

Assigning via the handset

...

1. Go to WMS -> Devices -> W-AIR devices
   
   
   

   
   

2. Choose the handset and click Assign to user
   
   

   
   

   
   

3. Enter user extension and click Save

• Fix parts connected to Aruba HP switch will have expected jitter < 300ns
• Fix parts connected via 3 layer switch will have expected jitter < 500ns
• Fix parts connected via 7 layers switch will have expected jitter < 2000ns 

Diagnostics Logging 

...

Radio Coverage

When checking the Radio Coverage on the web interface of the Base station -> menu Multi Cell, pay attention that the coverage values of every connected base in DECT sync source column are infinite by design.
