Description

A kind of multilink low latitude wideband Communication apparatus based on 3G/LTE

Technical field

The utility model relates to a kind of multilink low latitude wideband Communication apparatus based on 3G/LTE.

Background technology

At present, existing product does not have similar airborne communication products, and immediate terrestrial techniques adopts GSM short message or GPRS communication mode, and it mainly exists following problem:

1. existing product does not have similar airborne communication products, only the product of face product or employing GPRS;

2. existing product limited bandwidth, main employing GPRS communication mode, traffic rate is very low;

3. existing network coverage rate is lower, flies possibly cannot receive mobile base station number in some areas and cause GPRS normally to work, and after adopting 3G/LTE, the guarantee section communication pattern of the communication energy maximum magnitude of multiple system is working properly;

4. the product of existing GPRS is due to self system reason, the ability of anti-Doppler effect is too late with 3G/LTE system far away, particularly in high-speed mobile situation, the communication performance of GPRS will decline a lot, and adopts the product of this technology performance on the aircraft of high-speed mobile to be obviously better than original technology.

Utility model content

The utility model object is that the defect existed for prior art provides a kind of multilink low latitude wideband Communication apparatus based on 3G/LTE.

The utility model for achieving the above object, adopt following technical scheme: a kind of multilink low latitude wideband Communication apparatus based on 3G/LTE, comprise main control computer module, its input is connected with interface module and ethernet module respectively, its output is connected with connector respectively by 3G module and LTE module, and the output of described connector is connected with multimode antenna; Also comprise the power module for each module for power supply.

The beneficial effects of the utility model: major advantage is as follows:

1,3G/LTE communication first is introduced the communications field, airborne low latitude;

2, for low latitude communication access provides more communication pattern and available link selection mode;

3, better communication bandwidth, by multilink converged communication, provides more communication links, bandwidth is increased greatly;

4, by the integration to existing mobile communication resources, lower installation cost and use cost is provided;

5, better wireless network covers, and plurality of communication schemes can ensure to have wider wireless coverage ability;

6, high-speed mobile characteristic is better, and in the communication system of 3G and LTE, be greatly improved all than before to the mobility of terminal equipment and ability, during high-speed mobile, property retention ability is stronger, and abnormal mobile aspect has natural advantage.

Accompanying drawing explanation

Fig. 1 is schematic diagram of the function of the present utility model.

Embodiment

Shown in Fig. 1, relate to a kind of multilink low latitude wideband Communication apparatus based on 3G/LTE, comprise for carrying out control treatment to other module of device interior, network data forwards, and the main control computer module of protocol conversion, its input is connected with interface module and ethernet module respectively, its output is connected with connector respectively by 3G module and LTE module, and the output of described connector is connected with multimode antenna; Also comprise the power module for each module for power supply.

Wherein, above-mentioned 3G module and LTE module are used for the process of public wireless mobile communication transceiver; Above-mentioned multimode antenna is responsible for the transmitting-receiving of multimodal radiofrequency signal; Connector is responsible for communication module (i.e. 3G module and LTE module) and is connected with the effective of multimode antenna, for realizing the multiplexing of aerial signal.Ethernet module is responsible for wireless data to be converted to Ethernet data, and provides the communication interface etc. of internal network; Interface module is responsible for equipment I/O and equipment debugging, software upgrading etc.; Power module is responsible for airborne power supply to be converted to internal electric source, and the power supply for other modules inputs.

During design, adopt 3G communication system (WCDMA, CDMA2000, TD-SCDMA) communication module, the communication technology of multilink is formed together with LTE communication module (TD-LTE, FDD-LTE), the modem development of integrated above-mentioned standard is airborne communication control, and adopt money band antenna, for building the broadband Ground-to-air Communication Link under low-latitude flying scene, multiple link can work simultaneously, also can work independently, for the broadband connections application under the scene of low latitude.

In addition, the correlation module related in this equipment is hardware system module or is the functional module that prior art Computer Software program or agreement combine with hardware, computer software programs involved by this functional module or agreement itself be the technology of well known to a person skilled in the art, or the adaptability revision being only used to adapt to new hardware system and doing, the adaptation of this computer software programs or agreement does not need those skilled in the art to pay creative work, they neither the improvements of native system, but a kind of known usual modular system, native system be improved to interaction relationship between each module or annexation, be and the structure of the entirety of system improved, to solve native system relevant art problem to be solved.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
