RSSI
Receiver Sensitivity Index. RSSI is a value to show the Receiver Sensitivity of the remote
wireless device. In general, remote APs with stronger signal will display higher RSSI
values. For RSSI value, the smaller the absolute value is, the stronger the signal. For
example, “-50db” has stronger signal than “-80dB”. For outdoor connection, signal
stronger than -60dB is considered as a good connection.


RTS

Request To Send. A packet sent when a computer has data to transmit. The computer will
wait for a CTS (Clear To Send) message before sending data.

RTS Threshold

RTS (Request to Send). The RTS/CTS(clear to send) packet will be send before a frame
if the packet frame is larger than this value. Lower this value can improve the
performance if there are many clients in your network. You can try 1500, 1000 or 500
when there are many clients in your AP’s network.


SNMP
Simple Network Management Protocol. A set of protocols for managing complex networks.
The SNMP network contains three key elements: managed devices, agents, and
network-management system (NMS). Managed devices are network devices that contain
SNMP agents. SNMP agents are programs that reside SNMP capable device’s firmware to
provide SNMP configuration service. The NMS typically is PC-based software that can
monitor and control managed devices remotely.


SSH

Developed by SSH Communications Security Ltd., Secure Shell is a program to log into
another computer over a network, to execute commands in a remote machine, and to move
files from one machine to another. It provides strong authentication and secure
communications over insecure channels. It is a replacement for rlogin, rsh, rcp, and rdist.
