5.3.5 Possible communications disturbances
Possible communication disturbances include the following:
Noise can be caused by electronic devices and radio transmitters.
Path-loss occurs as the strength of the received signal steadily decreases in
proportion to the distance from the transmitter.
Shadowing is a form of environmental attenuation of radio signals caused by
hills, buildings, trees or even vehicles. This can be a particular problem inside
buildings, especially if the walls are thick and reinforced.
buildings, especially if the walls are thick and reinforced.
Multi-path fading is a sudden decrease or increase in the signal strength.
This is the result of interference caused when direct and reflected signals
reach the antenna simultaneously. Surfaces such as buildings, streets,
vehicles, etc., can reflect signals.
reach the antenna simultaneously. Surfaces such as buildings, streets,
vehicles, etc., can reflect signals.
Hand-over occurs as you move from one cell to another in the GSM network.
Your mobile application call is transferred from one cell to the next. Hand-over
can briefly interfere with communication and may cause a delay, or at worst, a
disruption.
