As illustrated, F is the base station facility; T is the signal receiving and emitting antenna of the base station; A is the connecting end of the signal receiving and emitting system duplexer of the base station and the signal receiving and emitting antenna of the base station; CA>, CB1>, CB2>, and CBN> are isolating capacitances; LT> and LD> are transmission leads; 1, 2 and N are mobile phones; B1, B2, and BN are the outer connecting antenna ends of the mobile phones; T1>, T2> and TN> are the original signal receiving and emitting antennas of the mobile phones. The utility model is characterized in that the phone users with different phone numbers can be combined together using the same phone wire; then the mounting of the wire phone can greatly save materials and labors; and the cost is cheaper. Furthermore, compared with the mobile phone, the utility model has the advantages of more convenient mounting, uneasy wire tapping, uneasy stealing call, no electromagnetic radiation pollution, reliable and stable signal, and more conveniently fixed point transmission.
Description
Technical field the utility model belongs to communication technical field.
Two kinds of wired landline telephone of telephonic communication system that background technology is generally used at present and mobile phones.Wired landline telephone, the lead transmission manner is adopted in the transmission of phone information, and have call-information and stablize, the characteristics that communication effect is good, but every phone all will have special line to be connected with the telephone exchange station, and the setting of phone is comparatively loaded down with trivial details, and cost is higher; And, just can intercept the call scenarios on this telephone wire as long as on telephone wire and connect telephone set, confidentiality is relatively poor, also easily by free call on sb. else's expense through illegal means.Mobile phone, the mode of wireless radio transmission is adopted in the transmission of phone information, has mobility, characteristics easy to use, but exist radio-wave radiation that the end user is produced harmful effect, can cause interference to some sensitive electronic equipments; Signal is coated with the dead angle, reliability and speech quality that influence is used.
Summary of the invention the utility model is in order to provide a kind of, and novel telephone system is compared with mobile phone, and electromagnetic-radiation-free pollutes, and signal is reliable and stable, and the fixed point transmission is more convenient, compares with existing wired landline telephone that cost is more cheap, performance is more superior.
The utility model is to be made of cell mobile communication systems, it is characterized in that base station equipment and each mobile phone user's signal contact, adopts the lead transmission.Concrete measure is that base station transceiver communication system duplexer and base station transceiver antenna connection terminal (A) are with isolation capacitance (C
A) connect the isolation capacitance other end and transfer wire (L
T) connect the other end of transfer wire and isolation capacitance (C
B1) connect the external antenna end (B of the isolation capacitance other end and mobile phone (1)

D) connect, and cancel each mobile phone (1,2 ... N) former Antenna Transmit-Receive (T
1, T
2... T
N).
The digital cable phone is developed by cell mobile communication systems and forms, the place different with cell mobile communication systems only is base station equipment and each mobile phone user's signal contact, adopted the lead transmission, radio signal, propagated by propagating to change in lead at free space originally, in addition, other characteristics and operation principles and cell mobile communication systems are identical.The telephone subscriber of different telephone numbers can be attempted by on the same telephone wire and use in the digital cable telephone system, and system adopts multiple access technique to determine the targeted customer.
The utility model is compared with mobile phone, and electromagnetic-radiation-free pollutes, and signal is reliable and stable, and the fixed point transmission is more convenient.The utility model makes the installation of telephone can save wide variety of materials and artificial because the telephone subscriber of different telephone numbers can be attempted by on the same telephone wire to be used; Because production technology and development of electronic technology, the electronic product price constantly descends, and communication equipment is more and more cheap, and artificial and material will be the principal element that influences the telephone installation cost, therefore, to compare price advantage obvious for digital cable phone and present telephone; And install more conveniently, difficult quilt is eavesdropped, and is difficult for by free call on sb. else's expense through illegal means.
