In addition, frequency duplex communications equipment can also be included in the sound volume regulating system, set with data extraction
Standby connection, ambient signal is carried for transmitting wirelessly the pocket from data extraction device.
FDD refers to that the transmission of up-link and downlink is carried out over different frequencies respectively.
In mode of frequency division duplexing, the transmission of up-link and downlink is carried out over different frequencies respectively.F1 and
F2 is respectively carrying out the transmission frequency and receives frequency of a certain mobile station of business transmission.
In first and second generation cellular system, it is substantially using FDD technologies to realize duplex transmission.Particularly
In generation cellular system, what it is due to transmission is continuous baseband signal, it is necessary to the up-downgoing of duplex is provided with different frequencies
Link channel.When transmission continuous information uses FDD technologies in first generation cellular system, transmitting-receiving two-end must all have generation different
The frequency synthesizer of carrier frequency, there must also be the duplex filtering for preventing transmission signal from leaking into receiver in receiving terminal
Device.In addition, for the ease of the making of duplexer, certain frequency interval will be had by receiving and dispatching between carrier frequency.In the second generation
In the systems such as GSM, IS-136 and IS-95, FDD technologies are also used.In such systems, because information is entered with slotted mode
Row transmission, transmitting-receiving can be carried out in different time slots, and the transmission signal of mobile station or base station will not produce to this receiver
Interference.So although with FDD technologies, it is not required that expensive duplexer filter.
The characteristics of fdd mode is the system on two symmetrical frequency channels of separation (up-downgoing frequency interval 190MHz)
Received and transmitted, channel is received and transmit to separate with protection frequency range.
Using technologies such as packet switch, the bottleneck of two generations development can be broken through, realizes high-speed data service, and frequency spectrum profit can be improved
With rate, increase power system capacity.But FDD must use paired frequency, i.e., third generation business is provided in every 2x5MHz bandwidth.
Which can make full use of the frequency spectrum of up-downgoing when supporting symmetrical service, but in asymmetrical packet switch (internet) work
When making, the availability of frequency spectrum then substantially reduce (due to low ascending load, cause the availability of frequency spectrum to reduce about 40%), at this point,
Tdd mode has the incomparable advantages of FDD.
