Specications
The Mesh network can easily be established using BR-400AN. As 2.4GHz/5GHz wireless communication bands are supported, the wireless devices can easily be joined to the Mesh network after they are connected to BR-400AN via a wired LAN.

2-1. What is Mesh Network?

In the Mesh network, several Mesh-network compatible devices (hereinafter, "Mesh devices") are
connected each other to congure a network without using Access Point.
in a wider area as the range of radio wave can be expanded by relay.
Also, Mesh devices communicate each other regularly to select a best route for relay. For example, if a
device (BR-400AN(3)) has malfunctioned when the route (1) is used, the rest of devices will continue
communication by rebuilding the route (2).

: All bands can be used to avoid interference.
Notes on using 5GHz band
Use of 5.2GHz band (W52) and 5.3GHz band (W53) outdoors is prohibited by the radio law. When BR-400AN is used outdoors, use W56 channels only and do not use W52/W53 channels.

BR-400AN User's Manual
DFS
BR-400AN supports DFS (Dynamic Frequency Selection) of the IEEE 802.11h wireless standard. When radar signals are detected, the channel will automatically be switched to avoid interference with radar systems (e.g. weather radar, etc).
One alternative channel can individually be set for W53/W56 channels beforehand, which will be used when radar signals are detected and the channel needs to be switched. When alternative channels are not specified or radar signals are detected even for that channel, the channel is randomly is changed.
- If Use DFS Band is ON, the DFS channels can be used (it is set to OFF by default).
TIP
- When BR-400AN is started with a DFS channel, it checks if there are radar signals on that channel. During
such a period, BR-400AN is unable to communicate.
- If radar signals are detected during or after BR-400AN is powered on, the channel needs to be changed in
order to avoid wireless interference. Therefore, if DFS channels are selected, the channel could be changed
automatically.
- The radar signals are monitored for a certain amount of time (*) after it is detected, while wireless
communication is disabled on BR-400AN then. Once radar signals are detected, the channel will not be
available for 30 mins. (* This time period diers depending on the country.)
- If radar signals are detected when they are monitored, the channel is switched to CH36. If radar signals are
not detected by MP/MAP, a scan is handled on CH36. When connectable MP/MAP are found, the channel is
switched to CH36. When it is not found, the same channel is used. This operation is processed only when
the channel is W53.
- When the channel is switched after radar signals are detected, the destination channel is notied to the
adjacent MP/MAP. MP/MAP switches the channel when it receives the notication.

2-8. Notes on Security

Because a wireless LAN uses electromagnetic signals instead of a network cable to establish communication with network devices, it has the advantage of allowing devices to connect to the network easily. However, a disadvantage of this is that within a certain range, the electromagnetic signals can pass through barriers such as walls, and if security countermeasures are not implemented in some way, problems such as the following may occur.
- Communication is intercepted by a third party
- Unauthorized access to the network
- Leakage of personal information (ID and Card information)
- Spoong and the falsication of intercepted data
- System crashes and data corruption
Nowadays, wireless LAN cards or access points are equipped with security measures that address such security problems, so that you can enable security-related settings for wireless LAN products in order to reduce the likelihood of problems occurring. We recommend that you make yourself fully acquainted with the possible implications of what might happen if you use a wireless product without enabling security features, and that you configure security-related settings and use wireless products at your own responsibility.

2-9. Restrictions

BR-400AN has the following restrictions.

Restrictions on DFS Channels

- If radar signals are detected again during the radar monitoring period that occurs as a result that radar signals are found when BR-400AN is started or operating (*), BR-400AN may not be able to join the network of adjacent MP/MAP.
- For some wireless environments, even if the destination channel is notified to the adjacent MP/MAP, the channel switch may not perform as the notication is not received correctly.
- If BR-400AN is restarted after it detected radar signals and switched the channel, BR­400AN starts with the pre-congured channel NOT with the channel it switched. If the channel is different from the adjacent MP/MAP, BR-400AN will not be able to join the same network.
(* This time period diers depending on the country.)

Product Installation and Radio Distance

BR-400AN radiates radio waves. Make sure that the top surface of BR-400AN (the surface with Silex logo and LEDs) face a target device. As a wireless communication distance is set to approximately 20m by defaults, place the target device within that range. The height of installation position must be about 2m from the ground.
TIP
Note
- An actual wireless communication distance may vary depending on wireless signal status on your
environment.
- By changing the transmission power setting on BR-400AN, the wireless communication distance can be
expanded / shortened. For details, refer to 5-1. Conguration Items on BR-400AN's Web Page - Option
