Glossary
Term
Definition
3GPP LTE
LTE protocol per “3rd Generation Partnership Project” a mobile telephon
e standards org.
5G-NR
The 5G radio system
5G NSA
Non-Stand-Alone flavor of 3GPP 5G-NR
... requiring concurrent 4G capability to function (currently typical)
5G SA
Stand-Alone flavor of 3GPP 5G-NR
... able to work without 4G capability (eventually, future)
5G TF
Verizon 5G Task Force (aka pre-5G)
ADC
Analog-Digital Converter (in electric circuitry)
Az, AZ, Azimuth
The “left
-to-
right” angle direction relative to
nearby gNB location
BW
Bandwidth
Commissioning
(Echo 5G) Installation and initial setup, which tunes the system to optimal functionality
CPE,
Customer
Premises Equip.
Typically: End-user obtained transceiver that distributes FWA broadband internet to devices
within the home via WLAN (Wi-Fi). Effectively replaces cable/DSL internet
dB, decibel
A relative unit of
power, used to express change in value as in “inc
rease of 3
dB”
--
presented on a logarithmic scale
dBm
A unit of level, indicating a power ratio expressed in decibels (dB) with reference to one
milliwatt (mW)
DL, Downlink
Data/information transmitted in the direction from gNB to CPE/UE
KPI
Key performance indicators: set of useful parameters that (in this case) CPE would report to
Echo 5G, and Echo 5G would display it for user
EIRP
Equivalent Isotropic Radiated Power, a measure of Transmit power
El, EL, Elevation
The
“up
-to-
down” angle direction rel
ative to distant gNodeB location
EN-DC
E-UTRA NR dual connectivity (a flavor of NR NSA deployment)
EVM
Error Vector Magnitude, a measure of quality of received signal
FWA
Fixed Wireless Access.
Gigabit speed
A term of user-perceived throughput, as in Gbits/second
gNodeB, gNB
5G NR base station
HBF
Pivotal Commware’s Holographic Beam Forming technology that enables Gigabit speeds
beyond the reach of cable and DSL
IDU
Indoor unit. The wireless power unit mounted on the interior side of the window.
Low-E glass
Low-Emissivity windowpanes, on which the coating that reflects sunlight also inhibits RF
signals from passing into a building
LTE
Long-term Evolution, generally referring to technology path toward 4G speeds
LTE Cat M1
A flavor of IoT (internet of things) technology under 3GPP LTE umbrella
