How does a wireless bridge solve the problem of hidden terminals? 5

The problem of hidden terminals in wireless bridges has always plagued the normality of the connection between the bridge and the client. It is difficult to make each piece of equipment work properly in terms of distribution. The Ansin TDM series products developed by Shenzhen Anxin Network System **** solve this problem.

It has a unique round-robin access to wireless access points, supports a maximum bandwidth of 150Mbps, supports N-head antenna output, and a unique TDM allocation algorithm to completely solve the wireless problem"Hidden endpoints" enrich security encryption and operations management functions.

Hide the terminal"(Hidden Stations): In the field of communication, base station A sends information to base station B, and base station C does not detect A and also sends information to B, so A and C send signals to B at the same time, causing signal conflicts, and eventually causing the signals sent to B to be lost. "Hide the terminal"It mostly occurs in large units (typically in outdoor environments), which results in a loss of efficiency and requires an error recovery mechanism.

This is especially important when it comes to transferring large volumes of documents"Hide the terminal"The occurrence of the phenomenon.

The RTS CTS protocol is the Request to Send Allow Send protocol, which is equivalent to a handshake protocol and is mainly used to solve the problem of hidden terminals. Hidden Stations means that base station A sends information to base station B, and base station C sends signals to B without detecting A, so A and C send signals to B at the same time, causing signal conflicts, and eventually causing the signals sent to B to be lost. Hidden terminals tend to occur in large units (typically in outdoor environments), which results in a loss of efficiency and requires an error recovery mechanism.

When it is necessary to transfer large files, it is especially necessary to prevent the occurrence of hidden terminals. The following solutions are provided. In the parameter configuration, if the RTS CTS protocol is used, set the maximum number of bytes to be transmitted--- once the data to be transmitted is greater than the upper limit.

In the field of communication, base station A sends information to base station B, and base station C does not detect A and also sends information to B, so A and C send signals to B at the same time, causing signal conflicts, and eventually causing the signals sent to B to be lost.

A communicates with B, and C is within the broadcast range of B, but C can't detect A, so A is a hidden terminal for C, C thinks he can communicate with B, but in fact he can't expose the terminal is similar, A communicates with B, C communicates with D, C is in the range of B and D, when B wants to send a message to A, it finds that CD communication occupies the channel, so a delay occurs, C is the exposed node of B, in fact, B can send a message to A. ReferenceIf you are good at English, you can take a look at this solution.

I don't know, are you talking about the broadcast and non-broadcast of the SSID?

Whether the two signal pins of RTS CTS are connected or not depends entirely on each other.

1) If the other party clearly stipulates that RTS CTS is required, there are two connection methods. The first is to < the RTS on your side - the CTS of the other side; The CTS on your side < – the RTS of the other side. Or in the second way:

Connect the other party's RTS to the other party's CTS.

2) If the other party doesn't need RTS CTS, then don't worry about it.

According to the RS232C protocol, RTS and CTS are a pair of transmission control signals. This signal is optional and not required when in use.

Terminal connection is the simplest and easiest way to connect. As long as you have an account on any host on the Internet, you can remotely log in to the computer through dial-up and PC telnet software, and use the Internet resources and service tools provided by the host. Terminal connectivity requires the user to:

A PC, a modem or a modem card, a common line, a number for the other party to dial, ordinary communication software, etc. In addition, you must apply for an account on an Internet host.
