•
Port Number
— A 16-bit number used by the TCP and UDP protocols to direct traffic on a
TCP/IP host. Certain port numbers are standard for common applications.
•
PRL
— Preferred Roaming List. A list that your wireless phone or device uses to determine
which networks to connect with when you are roaming (Network operator specific).
•
Protocol
— A standard that enables connection, communication, and data transfer between
computing endpoints.
•
Proxy
— A firewall mechanism that replaces the IP address of a host on the internal (protected)
network with its own IP address for all traffic passing through it.
•
Router
— A device that directs traffic from one network to another.
•
RSRP
– Reference Signal Receive Power. An LTE-specific measure of signal strength, similar to
RSSI, but RSRP measures lower than RSSI due to the method of calculation.
•
RSRQ
– Reference Signal Received Quality. A calculated value from RSRP and RSSI that provides
a measure of signal and interference.
•
RSSI
— Received Signal Strength Indicator. An estimated measure of how well a device can
hear a signal from an access point or router. RSSI value is pulled from the device’s Wi-Fi card
(hence “received” signal strength), so it is not the same as transmit power from an access point
or router.
•
SIM
— Subscriber Identification Module. Found in LTE and GSM network technology, the SIM is
a card containing identification information for the subscriber and their account. The SIM card
can be moved to different devices.
•
SINR
— Signal to Interference plus Noise Ratio.
An LTE-specific measure of signal quality, taking
interference and noise into account. SINR is a positive value, and higher numbers are better.
•
SMTP
— Simple Mail Transfer Protocol. The standard protocol for sending emails across the
Internet.
•
SNMP
— Simple Network Management Protocol. An Internet protocol used to manage and
monitor network devices and their functions.
•
SSID
— Service Set IDentifier. The name assigned to a Wi-Fi network.
•
TCP/IP
— Transmission Control Protocol/Internet Protocol. The set of communications
protocols used for the Internet and other similar networks.
•
TFTP
— Trivial File Transfer Protocol. An Internet software utility for transferring files that is
simpler to use than FTP, but does not provide user authentication and directory visibility
supported by FTP.
•
Telnet
— A user command and underlying TCP/IP protocol that allows a user on one computer
to log into another computer that is part of the same network.
