The utility model also provides a kind of radio transmitting device, it is characterized in that: include:
One transmitting-receiving pedestal comprises an antenna, and an end of this transmitting-receiving pedestal is electrically connected to the line end points of public's switched message network user side by one second cable; And
At least one communicator or information device, comprise one with the antenna of this transmitting-receiving pedestal with the radiotelephone frequency antenna of the number of delivering a letter mutually, reach one and be used for transmitting and separating the modulation of the received signal of this communicator of modulation or information device/separate modulation module of this communicator of modulation or information device.
Described radio transmitting device is characterized in that: this at least one communication device comprises telephone and facsimile machine.
Described radio transmitting device is characterized in that: this at least one information device comprises notebook computer, personal digital assistant device and modem.
After having adopted said structure, radio transmitting device of the present utility model, it comprises a transmitting-receiving pedestal and a Portable transceiver.One side of this transmitting-receiving pedestal is connected to the line end points of public's switched message network user side by one second cable, and can with radiotelephone frequency mutually the deliver a letter number of this Portable transceiver to commonly use on the market, therefore can avoid must not having in the directivity of known infrared transmission and the transmission path restriction of barrier.One side of this Portable transceiver provides jack, and for example a telephone line jack of commonly using can link general communication device respectively with it via one first cable.In other words, these communication devices and information device will carry out the remote signaling transmission via this first cable, this Portable transceiver, this transmitting-receiving pedestal, this second cable and this public's switched message network.This Portable transceiver can move to arbitrary position according to user's demand.In addition, because of the employed radiotelephone frequency of the utility model is a public frequency band, do not need prior application also not have specific communications protocol, and its wireless telecommunications module also becomes very cheap because of shiploads of merchandiseization, therefore can overcome the various shortcoming of using blue bud technology.
The function of this Portable transceiver also can be embedded within these communication devices and the information device, need additionally carry this Portable transceiver and this first cable to avoid the user.For the cable in office or family management, the also quantity of cable capable of reducing using and be easier to management.
Below, with embodiment the utility model is done further detailed description in conjunction with the accompanying drawings.
Fig. 1 is a known schematic diagram with most information device to user side line end points of cable connection.
Fig. 2 is the schematic diagram of first preferred embodiment of radio transmitting device of the present utility model.
Fig. 3 is the schematic diagram of second preferred embodiment of radio transmitting device of the present utility model.
Fig. 2 is the schematic diagram of first preferred embodiment of radio transmitting device of the present utility model.In Fig. 2, a transmitting-receiving pedestal 10 contains an antenna 101.One end of this transmitting-receiving pedestal 10 can be connected to the line end points of public's switched message network user side by one second cable 112, and carries out the remote signaling transmission by this public's switched message network.The antenna 101 of this transmitting-receiving pedestal 10 is to receive the signal that is transmitted from a Portable transceiver 12 with the radiotelephone frequency of commonly using on the market, and this transmitting-receiving pedestal 10 is changed this received signal, and carries out the remote signaling transmission via this second cable 112.On the other hand, this transmitting-receiving pedestal 10 is also transmitted by the signal that this second cable 112 receives from far-end, and after changing this received signal, the antenna 101 of this transmitting-receiving pedestal 10 is sent to a Portable transceiver 12 with the radiotelephone frequency of commonly using on the market.This Portable transceiver 12 contains an antenna 121 and at least one jack 122, wherein, this antenna 121 can be received and dispatched radiotelephone frequency mutually the deliver a letter number of antenna 101 to commonly use of pedestal 10 with this, and this jack 122, a telephone line jack of commonly using for example, can with general communication device, as phone 13, facsimile machine 14, or general information device, as notebook computer 15 and personal digital assistant device (PDA) 16 etc., link via first cable 111.In other words, these communication devices and information device will carry out the remote signaling transmission via this first cable 111, this Portable transceiver 12, this transmitting-receiving pedestal 10, this second cable 112 and this public's switched message network.
Because these communication devices and information device only link this Portable transceiver 12 with short-range first cable, the cable that therefore can solve conventional approaches reaches not manageable shortcoming in a jumble.Therefore this Portable transceiver 12 can move to arbitrary position according to user's demand, can solve these communication devices of difficult arrangement in the conventional approaches or the shortcoming of information device seated position.Therefore this transmitting-receiving pedestal 10 and this Portable transceiver 12 are the radiotelephone frequency numbers of delivering a letter mutually to commonly use on the market, can avoid must not having in the directivity of known infrared transmission and the transmission path restriction of barrier.At last, because of the employed radiotelephone frequency of the utility model is a public frequency band, do not need prior application also not have specific communications protocol, and its wireless telecommunications module also becomes very cheap because of shiploads of merchandiseization, therefore can overcome the various shortcoming of using blue bud technology.
Fig. 3 is the schematic diagram of second preferred embodiment of radio transmitting device of the present utility model.The maximum difference of the structure of Fig. 3 and the structure of Fig. 2 is the function of this Portable transceiver 12 is embedded within all communication device and information device.In other words, all communication devices, as facsimile machine 14 and radio telephone 18 etc., and information device, as notebook computer 15, personal digital assistant 16 and modem 17 etc., comprise an antenna 141,181,151,161 and 171 and one wireless signal modulation/separate modulation module (scheming not shown) respectively.This antenna 141,181,151,161 and 171 can with this antenna 101 of receiving and dispatching pedestal 10 with the radiotelephone frequency number of delivering a letter mutually, this modulation/separate received signal that the modulation module is used for transmitting of these communication devices of modulation and information device and separates these communication devices of modulation and information device.For the user, so can exempt the trouble of additionally carrying this Portable transceiver 12 and this first cable 111; And for the cable in office or family management, the quantity of cable capable of reducing using and be easier to manage also.
Shown also among Fig. 3 that this Portable transceiver 12 can be achieved by improveing a radiophone of commonly using 18.The side of this radiophone 18 contains a telephone jack 182, can reach the purpose of signal transmission thus with 111 bindings of one first cable with other communication devices or information device.
