INNOVATIVE TECHNOLOGIES TO EXPAND THE RANGE OF BLUETOOTH

Abstract

The article reveals innovative technologies to expand the range of Bluetooth. A review of the specifics of the formation of the signal coverage spectrum. The mechanism of operation of the Bluetooth network is structured, which allows to transfer information between its universities through the physical layer, while the network universities relay messages and work dynamically to transport information over the network. It is emphasized that to set up a network, each device must broadcast a list of available devices within its range and update its own table of available devices according to this list. It is emphasized that intermediate devices dynamically choose the path through which the message is sent, depending on the traffic and availability of devices, this procedure works in the case of large-scale data transmission networks based on Bluetooth, where repeaters are required. with retransmission in order to expand the latter throughout the network. It is noted that given the instability and variability of the structure of each set of messages, Bluetooth technology uses some parameters and procedures to control and regulate the reliability and efficiency of data transmission, which include: procedure for transmitting messages over the network; procedure for receiving and simultaneously transmitting messages via Bluetooth; the procedure for publishing messages; accidental delay procedure. The architecture of the proposed technology to expand the range of Bluetooth, which is based on the involvement of intermediate devices between sender and receiver. The routing algorithm operating within the proposed network is a distance vector routing algorithm. It is emphasized that the determination of the level of the received signal when sending a message is based on the received level of filtering, and the median filtering is formed as a method of nonlinear data filtering. It is noted that in order to improve the quality of determining the existing level of the spectrum range, the constant and the index of losses along the way should be optimized to obtain values of parameters that correspond to environmental influences.
