Recommended Posts

What is the distance found under Wireless Advance Settings is for? When do we change it's value?

The "Distance" setting that can be found in the Wireless Advance Setting refers to the ACK. You can change the setting when the Wireless Bridge is more than a kilometer a part from each other.

In data networking and telecommunications, an acknowledgement (or acknowledgment or ACK) is a signal passed between communicatingprocesses or computers to signify acknowledgement, or receipt of response, as part of a communications protocols. For instance, ACK packets are used in the Transmission Control Protocol (TCP) to acknowledge the receipt of SYN packets when establishing a connection, data packets while a connection is being used, and FIN packets when terminating a connection.

Distance -Specify the distance between Access Points and clients. Longer distances may drop high-speed connections .

It takes into account the propagation delay time for the signal to get to the other side of the link.  Even at the speed of light which the signal is traveling at, those few microseconds will cause issues if not accounted for.  Because they need to talk back and forth, this communication must be in sync with one another.  The setting actually matters.  I did a link 4 miles and when I changed the setting from 1km to 7km I saw a huge improvement is throughput.

We'll take note of that Daniel. A good reminder to get a better throughput specially for long range point-to-point communication.

Here are some information about the acknowledgement and ACK timeout with different distance and ieee802.11 series for reference.
