SSID and WMM-AC
Service Set Identifier (SSID)
The Service Set Identifier (SSID) is an identifier that specifies a particular
802.11 wireless LAN. The SSID can be up to 32 characters long.
Wi-Fi Multimedia Admission Control (WMM-AC)
WMM-Admission Control allows the AP to prevent the wireless medium from
being oversubscribed. When WMM-AC is used and if a phone in an active call
roams to an AP that does not have sufficient capacity available, the AP will
deny the handset’s request for bandwidth and the handset will find another
AP with adequate bandwidth to ensure good call quality.
The detailed steps can be found in step
12 in Network Parameter Procedure .
Regulatory Domain and Radio Settings
Regulatory Domain
In order to conform to frequency settings regulated by different countries, you
must identify a domain and select either the 2.4 GHz or 5 GHz band. If you
select the 5 GHz band, you must also select the sub-band(s) used by the APs in
your facility.
Select the regulatory domain according to your country of operation. If you are
in North America, only regulatory domain 1 ispermitted although other
regulatory domains may be available. Not all regulatory domains may be
available on your SpectraLink 8400 Series Handsets.
You must set the regulatory domain before the handsets can be used. There is no
default setting for this option and the handsets will not associate with an AP until
this option is set.
Setting the correct regulatory domain ensures that the phone complies with local
regulatory requirements for your location.
If you are in North America, only regulatory domain 1 is permitted. If any other
domain is selected, the error message ‘Invalid Regulatory Domain’ appears once
the handset is restarted and the handset will not associate with an AP. If this should
occur, check the label on the handset for the FCC certificate to verify that the
handset is for North America only, change the regulatory domain to 1 and update
the handset’s configuration.
