Mikrotik How To

The new 5GHz super high power wireless card for long range links and powerful access points. This is the professional choice for reaching the last mile. 800mW transmit power will give you the ability to reach even further than before.

The card features built-in LED indicators for wireless mode, connection status (connected, searching, disabled), TX and RX activity and wireless signal strength - just looking at the card will help with installation and alignment. The card comes with a preinstalled industrial grade heatsink, one MMCX connector and nine LED indicator lights.

Due to local regulations, currently we can sell R5SHPn only to countries outside European Union.

Wireless retransmission is when the card sends out a frame and you don't receive back the acknowledgment (ACK), you send out the frame once more till you get back the acknowledgment. Wireless retransmits can increase the latency and also lower the throughput of the wireless link.

To check if the wireless connection has wireless retransmissions you need to compare two fields in the wireless registration table: frames and hw-frames. If the hw-frames value is bigger than frames value then it means that the wireless link is making retransmissions. If the difference is not so big, it can be ignored, but if the hw-frames count it two, three or four times or even bigger than the frames count then you need to troubleshoot this wireless connection.

We tested a pair of RB600A devices, each populated with the new R52n card, that were each connected to a pair of antennas. Running a bandwidth test from a RouterBOARD 1000 on each end, we achieved up to 30000pps and 194.3Mbps throughput. The applications are limitless. With new laptops supporting 802.11n by default, you can increase your local network capacity four times of the previously possible speeds.

To Prevent Self Interference With 3 Mini PCI in One Board, there is Adaptive Noise Immunity (ANI). There are 2 choises of ANI, ap-and-client-mode dan client-mode.

Use ap-and-client-mode if the RB mode is ap-bridge
Use client-mode if the RB mode is (mikrotik only)

To Activate ANI tool is:

DBii-F20 wireless minipci card work at 2,4GHz, output power 500 mWatt have Rx sensivity until -97 dbm. Include pigtail MMCX to N-Female.
