Cluster operation mode
Description
The cluster operation mode allows to manage devices in a cluster simultaneously, that sufficiently improves operation efficiency while deploying, configuring or exploiting a wireless network.
...
WOP-2ac announces its affiliation to a cluster through a special protocol. The device sends broadcast UDP packets to LAN with data on affiliation to a particular cluster. Thus, all the access points included to a cluster exchange data among them, identify a master of the cluster and its configuration. The master carries out an inventory of the devices in the cluster and always controls the quantity of the access points in the cluster and their addresses.
Installation
It is sufficient that only one access point be configured when deploying a network. For providing data exchange among devices in a cluster, you should install a DHCP server for network addresses distribution.
...
After installing the first access point, you do not need to configure the rest, it is sufficient to connect them physically to the network. The devices will obtain network addresses, define the master of the «default» cluster and will be automatically configured according to the master configuration.
Cluster configuration

To view the statistics, select necessary value and click «Go» in the «Display» section. The following parameters might be viewed:
- AP Location – access point’s location. The value is obtained from location description on the «Basic Settings» tab;
- User MAC – MAC address of client’s wireless device;
- Idle – average time that the device has been in stand-by mode (when the device does not receive or transmit data);
- Rate – transmit data rate between an access point and a particular client, in Mbps;
- Signal – a level of signal received from an access point;
- Rх Total – total number of packets received by a client within current session;
- Transmit Total – total number of packets transmitted by a client within current session;
- Error Rate – total number of packets dropped by an access point within current session;
To view correspondence of access points in a cluster and wireless networks detected by these devices, switch to the «Wireless Neighborhood» tab. There is a table, on the «Wireless Neighborhood» tab, that shows which wireless networks are detected by each access point and what signal level each access point accept.
According to this table, spectral analysis of the whole network might be carried out and there is an opportunity to estimate interference influence to each access point. It will help you to estimate better location of access points among coverage area and to define locations with exceeding level of noise. The top string of the table contains data on each radio interface of access points included in a particular cluster. The left column contains data on wireless networks which are defined by the devices in the cluster. A value of signal level of each access point is displayed in the top-right cell of the table.
...

The table «Proposed Channel Assignments» contains data on available channel values, which the radio interface will switch to if optimal channel selection has been launched:
- IP Address – IP address of the access point in the cluster;
- Radio – MAC address of a radio interface of the access point in the cluster;
- Proposed Channel – a channel number to which the radio interface will switch when optimal channel selection is launched.
Firmware update
The operation in the cluster mode allows to perform automatic firmware update for all the access points in the cluster without using external systems or controllers.
Firmware update might be performed:
