Abstract
The utility model discloses a GSM digital enclave companding system which relates to the field of communication, and comprises a near-end machine, at least a far-end machine, and a GSM base station, wherein the GSM base station is connected with the near-end machine which is provided with a relaying antenna A, the far-end machine is provided with a relaying antenna B and a retransmission antenna. In the utility model, the companding technology is utilized for solving problem that the traditional GSM network solves the communication problem in regions where people are scattered or mountain areas by tower amplification and pulling away, high frequency wave is compressed into low frequency wave, and the diffraction ability of the low frequency wave is utilized for ultra far distance cover.
Description
Technical field
The utility model relates to a kind of communications field, relates in particular to a kind of GSM numeral enclave companding system.
Background technology
The rural area radio mobile communication utilizes the on-air radio channel to come communication, because radio transmission is subjected to the influence of topography and geomorphology atural object bigger, and the quantity of base station and lay the place and be subjected to certain restriction, therefore in mobile communication network, have many wireless coverages blind area or wireless signal interference range, cause the mobile subscriber can not access, call drop or speech quality reduces.
Enclave companding system is one of network and replenishes, and is that companding system in enclave can replace the base station and realize wireless coverage under the outstanding situation of the primary problem that solves and capacity contradiction in covering.
But there is following deficiency in existing enclave companding system: frequency-selecting realizes weak effect; Overlay area speech quality is poor; The system noise sound pitch is difficult to realize that one drags many situations.
Summary of the invention
In order to solve the deficiency that prior art exists, the purpose of this utility model is to provide a kind of GSM numeral enclave companding system, is the system that is applied to have in the GSM network higher noise inhibiting ability.
To achieve these goals, the technical solution adopted in the utility model is such: comprise near-end machine, at least one remote termination, also comprise the GSM base station, described GSM base station links to each other with the near-end machine, and described near-end machine is established relaying antenna A, and described remote termination is established relaying antenna B and retransmitting antenna.
As preferably: described GSM base station links to each other with described near-end machine by wireless channel or coupler.
Compared with prior art, advantage of the present utility model is: utilize companding technology to solve traditional GSM network and put, zoom out with tower and solve mountain area or personnel and live and relatively disperse local communication issue, with high frequency waves boil down to low frequency wave, utilize diffraction, the diffracting power of low frequency wave again, carry out overlength distance and cover.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of GSM numeral enclave companding system comprises near-end machine 3, at least one remote termination 4, also comprises GSM base station 1 that described GSM base station 1 links to each other with near-end machine 3, described near-end machine 3 is established relaying antenna A, and described remote termination 4 is established relaying antenna B and retransmitting antenna.Described GSM base station 1 links to each other with described near-end machine 3 by wireless channel or coupler 2.
