NanoStation M2
Select the Channel Spectrum Width
(Access Points) according to the SSID setting. Access Point operating in WDS mode should have the same SSID as the WDS Peer in order
to establish the connection automatically while Auto option is enabled. This configuration is also known as the repeater mode. AP WDS
Auto option cannot be selected if any type of WPA or WPA2 security is used as WPA requires different roles on AP configuration
(authenticator or supplicant).
Note: Access Point operating in WDS mode and all the WDS Peers must operate on the same frequency channel, use the same channel
spectrum width and the same security settings.
SSID: Service Set Identifier used to identify your 802.11 wireless LAN should be specified
while operating in Access Point or Access Point WDS mode. All the client devices within the
range will receive broadcast messages from the access point advertising this SSID.
While operating in Station or Station WDS mode, you should specify the SSID of the
Access Point the AirOS v5.3 device is associated to. There can be several Access Points with an identical SSID. If the SSID is set to "Any"
the station will connect to any available AP.
The list of the available Access Points can be retrieved using the Select button (not
applicable to Access Point mode). This control activates Site Survey tool that is used for the
AP selection. Site Survey will search for the available wireless networks in the range on all
the supported channels and will allow you to select one for association. In case the selected
network uses encryption, you’ll need to set security parameters in Wireless Security section.
Select the Access Point from the list and click Select button for association.
Click Scan button to refresh the list of available wireless networks. Site Survey channel scan list can be modified using the Channel Scan
List control.
Hide SSID control will disable advertising the SSID of the access point in broadcast
messages to wireless stations. Unselected control will make SSID visible during network
scans on the wireless stations. Control is available while operating in Access Point mode only.
Lock to AP MAC: This allows the station to always maintain connection to a particular AP
with a specific MAC (applicable to Station and Station WDS mode only). This is useful as sometimes there can be few identically named
SSID's (AP's) with different MAC addresses. With AP lock on, the station will lock to MAC address and not roam between several Access
Points with the same ESSID.
Country Code: Different countries will have different power levels and possible frequency selections. To ensure device operation follows
regulatory compliance rules, please make sure to select your correct country where the device will be used. The channel list,
output power limits, IEEE 802.11 and Channel Spectrum Width modes will be tuned according to the regulations of the selected country.
Additionally, please consult the compliance guide (http://www.ubnt.com/wiki/RF_Compliance) for further explanation of international
compliance requirements.
IEEE 802.11 Mode: This is the radio standard used for operation of your AirOS powered
device. 802.11b, 802.11a and 802.11g are old 2.4GHz mode, while the 802.11n (2.4GHz
and/or 5GHz) is newer standards based on faster Orthogonal Frequency Division
Multiplexing (OFDM) modulation. For more information, please consult 802.11 compliance
guide (http://www.ubnt.com/wiki/RF_Compliance) .
M900 Series devices supported IEEE 802.11 mode:
A/N mixed – connect to an 802.11a or 802.11n network (selected by default). This mode offers better compatibility.
M2 Series devices supported IEEE 802.11 mode:
B/G/N mixed – connect to an 802.11b, 802.11g or 802.11n network (selected by default). This mode offers better compatibility.
M3 Series devices supported IEEE 802.11 mode:
A/N mixed – connect to an 802.11a or 802.11n network (selected by default). This mode offers better compatibility.
M365 Series devices supported IEEE 802.11 mode:
A/N mixed – connect to an 802.11a or 802.11n network (selected by default). This mode offers better compatibility.
M5 Series devices supported IEEE 802.11 mode:
A/N mixed – connect to an 802.11a or 802.11n network (selected by default). This mode offers better compatibility.
Channel Width: This is the spectral width of the radio channel. Supported wireless channel
spectrum widths:
5MHz – is the channel spectrum with the width of 5 MHz (known as Quarter-Rate
mode).
10MHz – is the channel spectrum with the width of 10 MHz (known as Half-Rate mode).
20MHz – is the standard channel spectrum width (selected by default).
40MHz – is the channel spectrum with the width of 40 MHz.
Auto 20MHz/40MHz – only available in Station (or Station WDS) mode. It offers better compatibility.
Reducing the spectral width provides 2 benefits and 1 drawback.
Benefit 1: It will increase the amount of non-overlapping channels. This can allow networks to scale better.
Benefit 2: It will increase the PSD (power spectral Density) of the channel and enable the link distance to be increased.
