L

LOS and NLOS
Line-of-sight propagation refers to electro-magnetic radiation
including light emissions moving in a straight line. The rays or
waves are diffracted, refracted, reflected, or absorbed by
atmosphere and obstructions with material and usually cannot
move above the horizon or behind obstacles.
NLOS is Non Line-of-sight.
Load
A device that consumes electrical power.
Lux
The lux (symbol: lx) is the SI unit of illuminance and luminous
emittance. It is used in photometry as a measure of the apparent
intensity of light hitting or passing through a surface.
M
Means…
MHz
Megahertz is the same as 1,000,000 Hz
mW
Milliwatt - The milliwatt (symbol: mW) is equal to one
thousandth (10
–3
) of a watt.
MPEG
Moving Pictures Experts Group.
Modulation
To change the output of a transmitter in amplitude, phase or
frequency in accordance with the information to be transmitted.
Data is superimposed on a carrier current or wave by means of a
procedure called modulation. Signal modulation can be done in
one of two ways: analogue and digital. In recent years, digital
modulation has been getting more usual, while analogue
modulation methods have been used less. There continues to be
plenty of analogue signals around, but, and they will probably not
become totally extinct.
Multicast
Multicasting is sending data from a sender to multiple receivers
where each receiver signals that they want to receive the data.
N
Means…
nm
A nanometre (American spelling: nanometer; symbol nm) is a
unit of length in the metric system, equal to one billionth of a
metre (i.e., 10
-9
m or one millionth of a millimetre).
