Product Descript ion The BreezeNET B300 device comprises an Outdoor Unit and an Indoor Unit to be used with anexternal antenna providing two N-type ports or integrated antenna to build a high-capacity MIMOpoint-to-point link over long distances. Implemented in a robust all-weather metal enclosure,BreezeNET B300 equipment can be used to create a point-to-point wireless links with capacity upto 250 Mbps at distances reaching 60 km and more (depending on country regulation).

NoteNumber

Description

1 Set distance from the CLI is not reflected in the WEB interface.

2 20 MHz bandwidth is not displayed in the CLI at command rf rf5.0

3 In sys log: invalid bit rate 300000, set bit rate to 130000 appears although the bit rateis correctly set and supported.

4 Air upgrade does not work via CLI configuration only.

5 In setups with one unit set to be DHCP server and the other set to be DHCP relay, theDHCP client is unable to receive IP from DHCP server through the DHCP relay.

6 Wrong values for TX power can be entered without any warning (e. g. 0, -0.5, 0.7).

7 Reported TX power in WEB interface or CLI may differ from the set power.

8 When the power is set to the maximum level (63mW/18dBm), ATPC disabled the unitreports 15 dBm instead of 18 dBm.

9 At the default settings, the channel BW is 20 MHz; when changing it to 40 MHz, themaximum bit rate is not change accordingly to the maximum value for the new BW.

NoteNumber

Description

10 The measured distance may differ from the real distance of the outdoor site.

11 After a factory reset is performed using the ERP console, the rf5.0 interface no longerappears in the web interface and also in the CLI. The unit needs to be restarted.

12 The unit accepts the command for activating the third antenna (-align 1,2).

13 Duplicate queue rules can be entered without any warning (e.g. The second rule hasthe same parameters as the first one).

Miscellaneous

In the upper channels (tests performed at the highest frequency on each bandwidthin 5.8 GHz) there are large power variations during transmitting due to a knownhardware issue caused by AGC self-oscillations due to declining VSWR in uppermostchannels (beyond the allowed in EN 302 502).

In 5 MHz bandwidth, the interferer dramatically damages the BreezeNET B300 linkquality when it transmits in the frequency shifted in both sides with 4 times thebandwidth length.

When the link quality is bad enough for the unit to transmit with the current bitrate,and if this bitrate is manually set or it iss the minimum bitrate for the workingbandwidth, then the throughput varies from the current value to 0 in a continuouslooping.

H05 hardware does not have the Real Time Clock (RTC) chip with integrated battery. Therefore, the modified date will not be kept after unit restart. SNTP protocol can beused to synchronize the date and time with an external NTP server only (sntp -server=IP_ADDR start).

Displayed noise floor cannot be considered as an accurately measured value.

In auto bit rate mode, the unit can work with a bit rate lower than the minimum set bitrate.

Managing one unit through the serial console and accessing the other unit throughthe link via telnet from the console menu of the first unit, and changing an RFparameter to the second unit which causes link loss, returning to the console menucan take up to one minute.
