SUMMARY
In the presented dissertation two types of computer networks
- technologies
of wire networks and technologies of wireless networks were studied, and the
following results were obtained:
1. The main characteristics of more modern technologies
- technologies of
wireless networks, which appeared as an alternative
to the technology of wire
networks, used since the middle of the twelfth century.
2. It is known that the construction of computer networks is based on a defined
topology. The study studied the optimality of the technology in relation to the
topology
of the bus, ring, star, tree and mixed (Mesh) network used in the
construction of computer networks.
3. On the basis of the classification of computer
networks in terms of the
volume of construction studied the effectiveness of these technologies, their
impact
on different areas of our lives, the general trends of development and prospects for
the future.
4. Then the effectiveness of LAN networks, technical requirements for their
installation and configuration of LAN and WLAN networks using wireless
technologies was studied in detail.
5. Planned and designed
a wireless local area network, protecting the
confidentiality of the configuration and
parameters of the WLAN network,
depending on the environment in which they are installed, locations and applications
of encryption WEP, WPA, W2A, WPA, 80, WPA, 80
and problem solving with
wireless networking technologies.
6. Besides, the main perspectives of the AD HOC network and MIMO
technologies have
been studied, as well as the factors limiting it.
