Description

A kind of GSM fixed wireless communication device

Technical field

The utility model relates to wireless communications application technical field, especially a kind of GSM fixed wireless communication device.

Background technology

GSM fixed wireless access equipment is that wireline telephone terminal is accessed GSM network by one, thus completes the equipment of voice communication, and it sets up a bridge between ordinary telephone set and GSM network; Existing Wireless Telecom Equipment, maintenance cost is higher, and business provides inconvenience, and then the life affecting people uses.

Prior art is difficult to the productive life needs meeting people, in order to solve above-mentioned Problems existing, the utility model proposes a kind of GSM fixed wireless communication device.

For realizing this technical purpose, the technical solution adopted in the utility model is: a kind of GSM fixed wireless communication device, comprises plain old telephone IC Card Telephone coin telephone module, GFRA equipment, GSM network; Described plain old telephone IC Card Telephone coin telephone module is arranged on GFRA equipment side, and described GFRA equipment is connected with GSM network controlled in wireless; Described GFRA equipment comprises rechargeable battery, telephone control module, governor circuit and radio receiving transmitting module; Described telephone control module and radio receiving transmitting module all with governor circuit control connection.

As further technical scheme of the present utility model: described telephone control module, governor circuit are all connected with rechargeable battery with radio receiving transmitting module.

As preferred version of the present utility model: described governor circuit adopts STC89C54 type single chip machine controlling circuit.

As further technical scheme of the present utility model: described telephone control module comprises subscribers feeder SLIC interface circuit, DTMF detects and signal tone produces circuit.

Compared with prior art, the utility model has following beneficial effect: this GSM fixed wireless communication device:

One, economical, operation maintenance expense is significantly less than wired system, and cost and range-independence, this is in rural area and outlying district its advantage especially aobvious;

Two, business can be provided rapidly, according to statistics, GFRA can come into operation at one month, wired access network then needs the time of 6 ~ 18 months, and in addition, wired access network also exists occupation of land, densely populated areas, city wiring difficulty and is vulnerable to the defects such as natural calamity destruction;

Three, capacity is large, and adopt MPS process, the technology such as frequency reuse, can extend one's service capacity;

Four, flexibility and changeability, without the need to predicting telephone traffic, can change at any time as required, and dilatation is convenient;

Five, adopt STC89C54 type single-chip microcomputer, have the beneficial effect of low-power consumption, high speed reliability service, overall structure is simple, practical, is easy to promote the use of overall structure simple, novel in design, practical, is easy to promote the use of.

In Reference numeral: plain old telephone IC Card Telephone coin telephone module 1; GFRA equipment 2; GSM network 3; Rechargeable battery 21; Telephone control module 22; Governor circuit 23; Radio receiving transmitting module 24.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Figure of description 1, in the utility model embodiment, a kind of GSM fixed wireless communication device, comprises plain old telephone IC Card Telephone coin telephone module 1, GFRA equipment 2, GSM network 3; Described plain old telephone IC Card Telephone coin telephone module 1 is arranged on GFRA equipment 2 side, and described GFRA equipment 2 is connected with GSM network 3 controlled in wireless; Described GFRA equipment 2 comprises rechargeable battery 21, telephone control module 22, governor circuit 23 and radio receiving transmitting module 24; Described telephone control module 22 and radio receiving transmitting module 24 all with governor circuit 23 control connection.

As further technical scheme of the present utility model: described telephone control module 22, governor circuit 23 are all connected with rechargeable battery 21 with radio receiving transmitting module 24.

As preferred version of the present utility model: described governor circuit 22 adopts STC89C54 type single chip machine controlling circuit.

As further technical scheme of the present utility model: described telephone control module 22 comprises subscribers feeder SLIC interface circuit, DTMF detects and signal tone produces circuit.

Action principle of the present utility model is:

1., after governor circuit receives the bell signal RING from radio receiving transmitting module, circuit and SuC is produced to home terminal telephone power ringing by signal tone;

2. governor circuit is between generation first sound ring back tone and rising tone ring back tone, sends incoming call display;

3. home terminal telephone machine user off-hook, both sides start call;

4. the process that terminates of double-talk is with outgoing process above.

The utility model is when designing: GSM network is accessed by antenna in GFRA equipment one end, and the other end connects common telephone terminal by telephone wire, as ordinary telephone set, IC Card Telephone machine, coin-box telephone set etc.GFRA equipment is equivalent between ordinary telephone set and GSM network, set up a bridge block.

To those skilled in the art, but the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
