Site research should also identify “interference” in the environment, such as building construction and others
equipment.
For example, wooden frame buildings allow signals to pass more freely than
reinforced concrete. This restriction
explains
why the signal sometimes falls quickly when the user changes rooms, even if the
user stays close to the body
the
point of attainment itself. Other durable components, such as steel fire doors
and elevator shafts, can also block reception.
Table
1 gives examples of the effects of building a building on the Internet. These
figures are classified by
2.4
Ghz. Loss generally doubles by 5Ghz. For example, if the user brings a tablet
from the room and access point
and
sitting in the hallway, the signal would fall by 20 dB. If the user climbs the
stairs and stands directly on that access
sure,
the reinforced ceiling between the device and the access point can cause a drop
of 25 dB. Charts are also important for
coverage
estimates in building areas where the tester can reach.
