How does RTS Threshold work in the CPE?
RTS/CTS adjustment may be required to minimize collisions among hidden nodes. This value determines the packet size at which the CPE issues the request to send (RTS) before sending a packet. The default value of RWB-MCPE works most of the time, however a low RTS setting may improve the throughput when many client devices are associating with an AP or when the clients are far from each other and can only detect the AP and not each other. This setting should be adjusted before trying to change the fragmentation threshold.
