Wi-Fi
This replaced WEP
WPA (Wi-Fi protected Access)
What regulatory body creates the rules surrounding CLI and OTA frequency allocation
the FCC
Attenuation
Difference in energy between two points (IE Distance)
Most common gauges of coax cable found in house wiring
RG-6, RG-59
RF
Radio Frequency
Unique physical address that each network connected device has
MAC (Media Access Control) Address
CLI
Cumulative Leakage Index
Insertion Loss
Flat loss that occurs when a passive device is installed in-line
components of coaxial cable
Center Conductor, Dielectric, bonded aluminum tape, braid, jacket (in some places)
MER
Modulation Error Ratio
Eero and Orbi are examples of what modern wireless network topology?
Mesh Network
benefit of dipole antenna for triangulation
directional, and picks up signal that is perpendicular or right angle to antenna elements
Typical loss through a 4 way splitter
7db
Minimum bend radius for rg-6
5"
Embedded Multimedia Terminal Adapter
Frequency bands used by Wi-Fi 6?
2.4 GHz, 5 GHz, 6 GHz
Aeronautical navigation and communication, amateur radio, public service, Cellular
Rule of thumb for rg-6 loss
6db/100' @ 750mhz
2db/100' @ 54mhz
impedance
75 ohm
MoCA
Multimedia over Coaxial Alliance
MU-MIMO
Multi-User, Multiple Input Multiple Output.
(Using multiple antennas to create multiple connections to a device at once, reducing the amount of time a device has to wait to send/receive data)
a leak must be logged if
greater than 20 microvolts per meter measured 10 ft from cable
Formula for estimating loss over distance
Footage X cable loss per foot (from manufacturer's chart)
Aerial Trespass
When an aerial cable drop crosses property that does not belong to the subscriber, like a neighboring property.
QAM
