Annotation:
With the increase in the number of electronic devices, their tasks became more
complex, and the range of services provided increased. Many radio tools must work
together to provide one or more services. Accordingly, interference in the radiation radio
receiver interferes with the correct reception of the signal, affects the circuit of the radio
receiver, and also violates the signals during transmission of radio waves. The article
discusses the causes and causes of problems arising from electromagnetic interference
in most communication facilities, industry and industry of the republic
Keywords: electromagnetic conditions, electronic devices, industrial radio
interference, high- frequency devices, ferrites, permalods, shielding.

Introduction.
In recent days in the country, including in Samarkand region, a lot of work is carried
out to improve the quality of mobile communications and mobile Internet. Certain work
is being carried out to improve coverage of all generations of mobile communications
(2G, 3G, 4G), from densely populated urban areas to remote regions, in order to provide
quality communication services to the population. As in any industry, this industry has
its own problems and challenges, which are difficult to solve
Main part.
Due to the high demand for mobile communications of the population, especially
our entrepreneurs, the production facilities of most entrepreneurs work in the basement
or the first floors of multi-storey modern houses, i.e. in rooms with bars on the outside
windows, preventing the penetration of mobile signals. That is why the installation of
repeaters that amplify cellular signals, imported by most of our entrepreneurs, not
having a certificate of compliance (often made in China), creates interference to the
antennas of mobile operators, leading to a deterioration of mobile and mobile Internet
quality
Such faulty repeater devices interfere with the connection of other mobile devices
by generating negative emissions on all mobile phone channels without amplifying the
signal of the required working channel
“MobiUz” Limited has received several complaints about this. Based on the
complaints received, a joint investigation was conducted to determine the operability
of the repeater devices. As a result, warnings were issued to owners of repeaters that
negatively affected the quality of mobile communications.

Despite the warnings, some of our entrepreneurs say: "I bought and installed this
device with my own money, I'm not going to turn it off, if I have to turn it off, bring
another device instead
Picture-1. Repeated devices that emit radiation that has an adverse effect on the
practice.
In order to positively address the issue and improve the quality of mobile
communications, mobile Internet, together with the Samarkand regional office of the
State Inspectorate for Information and Telecommunication Control, raids were carried
out to suppress the work of relay devices that negatively affect the quality of
communication.In this connection, we would like to appeal to our people!

Pictures 2. Incorrect retransmission system in the antenna installed
With the smart home system, you can control all types of lighting in on/off or
dimming mode, choosing the interface that is most convenient for you (a simple button
or a remote interface, such as a smartphone or remote control). You can specify which
lights or groups of lights should be turned on or off, as well as at what time of day the
lights should be turned on. You can also set different "scenes" (the first light at 100%
brightness, the second at 50% and the third at 20%) or lighting profiles (light at 70% for
an hour, then at 40% for 25 minutes, then at 15% for 5 minutes...). You can also use
another feature for the same purpose, since your home wireless network knows your
location, since your smartphone is always with you. So when you approach the house,
the light in the hallway will turn on automatically, without you having to turn it on from
your phone.
