Method for increasing the number of media playback devices by a communication base station

The present invention relates to the field of media content distribution; in particular, the present invention relates to a method for increasing a media playback device that is served by a communication base station.

The development and wide availability of high-band wireless networks have resulted in a large number of digital data transmitted wirelessly in a high-band manner, and wireless characteristics allow users to conveniently perform digital data transmission. However, for the growing number of users, there are currently difficulties in accommodating/satisfying data transmission expectations, on the grounds that the development of the data transmission infrastructure takes time (both in terms of planning and implementation) and significant financial investment. .

In the typical metropolis of all countries, numerous high-rise buildings inevitably lead to a very concentrated population density. Thus, a highly concentrated population density in metropolitan areas usually represents a large number of data network users in a narrow real estate area. When multiple users use the data network at the same time, the bandwidth sharing method of "shared bandwidth between users" generally leads to some unpleasant user experiences, including, for example, data delay, signal loss, data. Safe holes and so on.

Data networks typically rely on the use of communication base stations as relays for users to access data networks from different physical locations. However, each communication base station is generally capable of servoing a predetermined number of users and thus limits the number of users who can access the data network as desired.

In this regard, it would be desirable to enhance the communication base station to increase the number of users who can access the data network as desired.
