Appendix-frequently asked questions:
1 、 Wireless signal under the influence of factors?
1) Family spaces are crowded, there is not enough space open, where walls are
the most important obstacles in the room. As wireless local area network using a
wireless microwave frequency band. Microwave is the greatest feature of a
near-straight lines, diffraction from a very weak, so embedded in the barrier behind
wireless receiving equipment will receive very weak signal, or did not receive the
signal.
2) Physical obstructions, blocking not only microwave wireless signal, it also
absorbed electromagnetic energy, generate a weak flow discharge and, therefore,
wireless signals obstructions in the largest metal object in a family environment
is within the mesh reinforcement of floor slab, almost does not penetrate may signal
in this direction. To be able to penetrate, the signal is very weak.
3) IEEE 802.11b/g standard working frequency is 2.4GHz , and the industry on many
devices but also happens to work in the bands such as: microwave ovens, Bluetooth
devices, no rope telephone, refrigerator, etc. If the near strong magnetic fields
exist, then the wireless network will be affected.
4) If there are multiple wireless devices in a wireless environment could also
have a channel conflict, wireless signal crosstalk problem.
5) From the wireless devices and cable lines 100 meters in the radio transmission
towers, electric welding machine, strong signal interference sources such as trams
or high-voltage power transformers, or may cause interference to radio signals or
equipment.
6) Signal is outdoor propagation effects of weather conditions on wireless
signals are large, or if it is in a thunderstorm days when weather cloudy comparison
of signal attenuation, and signal transmission distance is farther in the sunny days.
2 、 How to improve the signal quality?
1) For wireless AP Select a best place of location. This placement locations are
as follows:
a , Position should be higher, for down radiation in high places, reducing
obstacles obstruct to minimize signal gaps;
b , location, location choice should make the signal as little as possible through
the wall, preferably in the rooms of the wireless client and wireless AP Visual
between.
