The method of estimating the bandwidth of communication channels and routing of Internet packets in the conditions of distance learning is considered. The research of media service platforms Microsoft Teams, Google Zoom and Skype was performed. A feature of the method is a combination of direct and indirect methods of estimating the bandwidth of communication channels. The application of this methodology makes it possible to evaluate existing market solutions for the implementation of distance education. This allows us to conclude on the feasibility of using the above services for distance learning. As a result, such a study helps to assess the congestion of channels and the effectiveness of remote monitoring of remote objects when the time delay in the delivery of information should not exceed a certain value. The results of the experiment showed that in general the considered platforms are very similar in the mode of conversation using only voice traffic. Bitrate in this case ranges from 100-130 Kbit/s. There is a significant difference between the platforms during the video traffic session. The differences between the platforms in the bitrate for this case are more than 90% (in some cases more than 100%). The study showed that the workload of the Internet channel on weekdays increased after ten o'clock in the afternoon. The Microsoft Teams platform provides the best video image quality. There are no differences between the platforms in terms of sound quality. General recommendations for organizing an online TV broadcast are as follows: for voice traffic, you can choose any of the proposed platforms, due to the fact that the difference in their characteristics is insignificant it's better to use Google Zoom to organize video communication; it's best to choose the Microsoft Teams media platform to organize a screen demonstration session. Studies have made it possible to assess the load that occurs during a communication session. The results of the experiment showed that the Google Zoom media platform, with the same quality of communication, creates fewer loads on the main Internet channels. The technical result obtained in this work is the creation of tools for selecting the optimal media platform for remote communication.

The standard of broadband mobile communication LTE can be used to build a mobile communication network in remote populations and provide the population with modern mobile communication services, such as video calls, data transmission, high-speed mobile Internet, Internet TV, etc. In this work, a LTE network has been designed, and the network capacity has been calculated for a certain area. Muynak of the Republic of Karakalpakstan, located in the northwest of the Republic of Uzbekistan, was taken as the territory. The paper presents the characteristics of the selected equipment required for the construction of the mobile network, calculations of network bandwidth, number of potential and active network subscribers, the number of base stations, the average bandwidth of the projected network, the average traffic per subscriber in the busy hour, the radio frequency plan, the geographical location of the base stations, and the LTE network design scheme has been developed. In addition, the characteristics of the number of potential subscribers are described in tabular form, as well as graphs of the number of base stations, the average bandwidth of the designed network, the total traffic of the designed network depending on the number of potential subscribers. The LTE network frequency plan has been developed for the city of Muynak. The designed network will increase the number of subscribers to 12,000 without reducing bandwidth.
