Receiver Sensitivity
Receiver sensitivity means how sensitive is the radio for receiving signal. In general; the
slower the transmission speed, the more sensitive the radio is. The unit for Receiver
Sensitivity is in dB; the lower the absolute value is, the higher the signal strength. For
example, -50dB is higher than -80dB.
RJ-45
Standard connectors for Twisted Pair copper cable used in Ethernet networks. Although
they look similar to standard RJ-11 telephone connectors, RJ-45 connectors can have up to
eight wires, whereas telephone connectors have only four.
Router
An IP sharing router is a device that allows multiple PCs to share one single broadband
connection using NAT technology. A wireless router is a device that combines the
functions of wireless Access Point and the IP sharing router.
SIGNAL STRENGTH
Receiver Sensitivity Index. SIGNAL STRENGTH is a value to show the Receiver
Sensitivity of the remote wireless device. In general, remote APs with stronger signal will
display higher SIGNAL STRENGTH values. For SIGNAL STRENGTH 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.
