131 connection uplink amplifirers 141, the downstream filtering that the downlink low-noise amplifier 120 of downlink radio-frequency signal unit passes through series connection
Device 130 connects downlink amplifirer 140, is provided between uplink combiner 180 and downlink combiner 181 and receives different operating frequency
Communication unit, communication unit includes gsm communication module, DCS communication modules, WCDMA communication modules, and the inside of controller is set
It is equipped with the monitor 160 of observation repeater working condition, 160 Connection Service device cloud platform of monitor.
Power supply 170 is mounted on inside upstream radio-frequency signal unit and downlink radio-frequency signal unit.Controller passes through modulation
Demodulator connects power detector.Upstream filter 131 and downstream filter 130 are respectively connected with frequency mixer, and frequency mixer is in series with
PA amplifiers.The working frequency range of gsm communication module is 890-960MHz, and the working frequency range of DCS communication modules is 1710-
The working frequency range of 1880MHz, WCDMA communication module is 1920-2170MHz.Controller is internally provided with isolation detection list
Member.
Working band：It should be consistent with the working band of GSM and CDMA.
Specified (maximum) output power, specified (maximum) gain (and gain-adjusted scope, range of AGC) and
Incoming level.This is one group of inter-related index, should be considered.
Usual peak power output in the case of no more than threshold limit value as defined in radio administration of the Ministry of Information Industry,
Several grades should be divided into select for user, downlink mainly considers to cover, and uplink ensures that base station satisfaction receives.Therefore, downlink is general
More than uplink.
In order to ensure stable output power and to avoid output nonlinear, the automatic growth control (AGC) with ≮ 10dB is seen
Come be it is necessary,
Bandwidth, passband fluctuation and Out-of-band rejection：This is the index of one group of correlate, especially bandwidth and with interior ripple
It is dynamic.In general, bandwidth refers to-three dB bandwidth, and passband fluctuation refers to the uneven degree in band.If it is required that passband fluctuation compares 3dB
Small, then-three dB bandwidth must be wider than distributing to its bandwidth, in this way, other channel certainly will be occupied.Therefore, passband fluctuation is most
Can only be 3dBp-p greatly.
Intermodulation and spurious emissions：Harmonic wave, intermodulation and it is spuious be all undesirable garbage signal, can propose it is the same will
It asks.To GSM repeaters, it is suitable by 300 609 requirement of YD/T 883-1999 and ETS, to CDMA repeaters, only presses
YD/T 1047-2000 are required.
Waveform quality：After cdma base station has the requirement to waveform quality (Rho), repeater to transmit CDMA signals, to this
Index may deteriorate, and should provide the deterioration amount of a permission.
After propagation delay time signal is by repeater, it is possible to create propagation delay time.The propagation delay time of broad band repeater is smaller,
Generally in 1 μ s or so；Frequency selecting repeater and frequency-shift repeater propagation delay time are bigger, may respectively reach 5 μ s and 10 μ s.
Noise coefficient：This is the characterization of repeater sensitivity, and the utility model is 4~6dB.
Voltage standing wave ratio proposes that the requirement of voltage standing wave ratio is needed for that can ensure that effective power is transmitted.According to power
The amount and real standard reflected, the utility model accomplish that it is feasible to be less than 1.4~1.5.
Operation and maintenance management：For Operation and Maintenance and management, making some signal designations, (such as output power indicates, power supply shape
State instruction etc.), power switch is set, and gain-adjusted button is necessary.As for need to need not propose remote monitoring or webmaster etc
Requirement, should depend on the circumstances.Can alternatively, having also need not be excessively complicated, complicated because repeater is not base station after all
Cost necessarily increases.
Safety requirements：There should be the requirements such as earthing or grounding means, pressure-resistant and insulation.
Since the indoor repeater in indoor repeater is simple type, therefore it is required that should be lower than outdoor version, especially output work
Rate, gain, noise coefficient, propagation delay time and voltage standing wave ratio etc..
In short, there are many technical parameters in repeater, as described above.But for a repeater, mainly there is working frequency
Scope, peak power output, gain ranging etc..
The utility model by tri- Communication System Designs of GSM, DCS, WCDMA on the circuit board (PCB) of a repeater,
It solves the problems, such as to occupy compared with multiple resource because installing excessive single system repeater.It is connected to the corresponding communication module of working frequency
In, thus fundamentally reduce the mutual crosstalk between different communication systems.Therefore, although the utility model by GSM, DCS,
These three communication systems of WCDMA are combined, but gsm communication module, DCS communication modules and WCDMA communication modules can be same
When handle the wireless communication signals of different frequency range, and interfere with each other very small.
Equipment working frequency can freely be configured by client.Believe for wireless forwarding, Bi-directional amplifier base station uplink and downlink link
Number, expanding mobile communication coverage.Device Host is divided into 4 relatively independent passages, and each passage supports that 1~3 carrier wave is adjustable,
And with passage turn-off function, independent shut-off can be carried out to each passage.Passage frequency-selecting uses digital frequency-selecting technology, can be effective
Base station carrier signal needed for amplification filters out other irrelevant signals, avoids area interference, improves speech quality and expands covering.Branch
Multifrequency extension is held, master-salve station shares remote monitoring system and realizes remote monitoring.
The utility model is effective to be：It is simple in structure, it supports the communication service of plurality of communication systems, is conducive to fast assembling
Network, covering is more flexible, and a base station is substantially circular covering, and multiple repeaters can be organized into a variety of mulching methods,
Handle the wireless communication signals of different frequency range simultaneously, and interfere with each other very small, practical performance is excellent, novel in design, be it is a kind of very
Good innovation scheme, there is market promotion prospect very much.
The present utility model is not limited to the above embodiments, and the above embodiments and description only describe this realities
With new principle, the utility model also has various change and changes on the premise of not departing from the spirit and scope of the utility model
Into these various changes and improvements fall within the scope of the claimed invention.The utility model requires protection scope is by institute
Attached claims and its equivalent define.
