METHOD OF WIRELESS COMMUNICATION BETWEEN SUBSCRIBERS AND BASIC STATIONS Russian patent published in 2018 - IPC H04W4/00 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to wireless communication. Method of wireless communication between subscribers 5 and base stations 1–4 is that subscribers 5 are divided into groups, each of which has subgroups, comprising each of at least one subscriber 5. Base stations 1–4 are divided into groups, with all base stations 1–4 of all groups having the same number of receiver channels of narrowband modulation (UNB), and all base stations 1–4 of each group have data transfer channels with the same time and frequency characteristics. Through all base stations 1–4 periodically send messages to all subscribers, including the corresponding numbers of groups of subscribers 5. All subscribers 5 receive messages, decode them, and if the group number of the corresponding subscriber 5 matches the group number in the received message, all subscribers 5 of this group send reply messages to base stations 1–4 using narrowband modulation UNB, moreover, sending of reply messages is carried out sequentially from all the subgroups of subscribers 5 of this group, while the subscribers of 5 subgroup send reply messages at different frequencies. Base stations 1–4 receive reply messages on all 5 frequencies corresponding to subscribers, decode them and form a database of response messages, which is used to generate subsequent messages, including the corresponding numbers of subscribers groups. Cyclic repeat periodic sending of specified subsequent messages and repeat the reception of reply messages.

EFFECT: technical result of the invention is to increase the network bandwidth, eliminate conflicts between transmitted data packets within the network, increase the coverage area of remote reading of sensors.
