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 3 key elements: managed devices, agents, and

network-management systems (NMSs). Managed devices are network devices that content

SNMP agents. SNMP agents are programs that reside SNMP capable device's firmware to

provide SNMP configuration service. The NMS typically is a PC based software such as HP

Openview that can view and manage SNMP network device 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.

SSL

Secure Sockets Layer. It is a popular encryption scheme used by many online retail and

banking sites to protect the financial integrity of transactions. When an SSL session begins,

the server sends its public key to the browser. The browser then sends a randomly

generated secret key back to the server in order to have a secret key exchange for that

session. SSL VPN is also known as Web VPN. The HTTPS and SSH management

interface use SSL for data encryption.
