Term Definition
Region Code A parameter that offers multiple fixed selections, each of which
automatically implements frequency band range restrictions for the
selected region. Units shipped to regions other than the United States
must be configured with the corresponding Region Code to comply
with local regulatory requirements.
RF Radio frequency. How many times each second a cycle in the antenna
occurs, from positive to negative and back to positive amplitude.
RJ-12 Standard cable that is typically used for telephone line or modem
connection.
RJ-45 Standard cable that is typically used for Ethernet connection. This cable
may be wired as straight-through or as crossover. Later modules auto-
sense whether the cable is straight-through or crossover.
Router Network element that uses the logical (IP) address of another to pass
data to only the intended recipient. Compare to Switch and Bridge.
RSSI Radio Signal Strength Indicator. A relative measure of the strength of a
received signal. An acceptable link displays an RSSI value of greater
than 700.
Self-interference Interference with a module from another module in the same network.
SFP Small Form-factor Pluggable
Simple Network
Management Protocol Standard that is used for communications between a program (agent)
in the network and a network management station (monitor). Defined in
RFC 1157. See http
://www.faqs.org/rfcs/rfc1157.html.
SM Customer premises equipment (CPE) device that extends network or
Internet services by communication with an Access Point Module or an
Access Point cluster.
SNMP See Simple Network Management Protocol, defined in RFC 1157.
SNMPv3 SNMP version 3
SNMP Trap Capture of information that informs the network monitor through
Simple Network Management Protocol of a monitored occurrence in the
module.
Spatial Frequency Spatial Frequency is associated with an LUID or SM registered with an
AP and it is visible on both AP and SM GUIs. It is grouped into bins
where each bin includes 32 consecutive spatial frequency values.
