Problems solved by technology

[0012] 1. Since there is no frequency planning between the piconets formed by Bluetooth, the frequency utilization rate is low, and the capacity that the network can accept is small
[0013] 2. There is no fixed frequency allocation rule between adjacent piconets, so that adjacent piconets may use the same frequency point, causing adjacent piconets to become sources of interference with each other, and there is a certain frequency gap between adjacent piconets. Conflict and interfere with each other, affecting the ability of the network to communicate

Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0031] The frequency hopping sequence generation method of this realization Bluetooth cellular network of the present invention refers to the frequency planning method of the Global System for Mobile Communications (GSM) group cellular network, first the whole frequency resource space is divided into a plurality of frequency hopping sequence sets, as Each Bluetooth piconet for networking is allocated a frequency hopping sequence set, and adjacent piconets are allocated different frequency hopping sequence sets. Then, in each bluetooth piconet master device, set the same number of frequency hopping sequence generators according to the number of frequency hopping sequences contained in its assigned frequency hopping sequence set. The frequency hoppin...

Abstract

This invention discloses a FH sequence generation method for realizing blue tooth cellular netting which divides the entire frequency resource space into multiple FH sequence sets. Every blue-tooth pico-net generates a FH sequence set in terms of the cellular netting mode by setting multiple FH sequence generators and false address information, adjacent pico-nets generate different FH sequence sets, which enlarges the total volume of the network, promotes its reasonable distribution and reduces interference among adjacent blue tooth pico-nets.

Description

technical field [0001] The invention relates to a method for using frequencies in a bluetooth network, in particular to a method for generating a frequency hopping sequence for realizing bluetooth cellular networking. Background technique [0002] Bluetooth technology is a standard for short-distance device interconnection using radio. With the gradual development of the access network side to wireless, Bluetooth technology has been gradually applied more and more widely. [0003] Bluetooth adopts decentralized or distributed network structure and short packet technology, and the duplex mode adopts time division duplex (TDD). Bluetooth supports both circuit-type data and packet-type data; it supports point-to-point and point-to-multipoint communications, and it works in the 2.4G industrial, scientific and medical (ISM) frequency band. Generally, each country only restricts this frequency band The transmission range and power size, but without approval and permission. [00...
