ESSID: The ESSID is a unique ID given to the Access Point. Wireless
clients associating to the Access Point must have the same ESSID. The
ESSID can have up to 32 characters.
Channel: You may select any of the available channels as an operational
channel for your Access Point.
RTS Threshold: RTS Threshold is a mechanism implemented to prevent
the “Hidden Node” problem. “Hidden Node” is a situation occurred when two
stations are within range of the same Access Point, but are not within range
of each other. Therefore, they are hidden nodes to each other. When a
hidden station starts data transmission with the Access Point, it might not
notice that the other station is already using the wireless media. When
these two stations send data at the same time, they might collide when
arriving simultaneously at the Access Point. The collision will most certainly
result in a loss of messages for both stations. Thus, the RTS Threshold
mechanism will provide the solution to prevent data collisions. When the
RTS is activated, the station and its Access Point will use a Request to
Send/Clear to send protocol (RTS/CTS). The station will send an RTS to the
Access Point, informing that it is going to transmit the data. Upon receipt,
the Access Point will respond with a CTS message to all station within its
