In an example, antenna 20 and 28 can be coupled to respectively on BTS-A16 and the BTS-B24 via link 32.Link 32 can be the link of any kind, for example comprises communication on microwave link, radio frequency (RF) cable link, the power transmission line, optical fiber, wireless optical link, coaxial cable, twisted-pair cable etc.
At link 32 may be in some embodiments of optical link (wireless or optical fiber), and each antenna 20,28 all may comprise the antenna terminal that can play a part antenna 20 and optical link coupling, will discuss in more detail below.Equally, in these embodiments, BTS-A16 and BTS-B24 may comprise BTS-A16 and BTS-B24 are coupled to base station terminal on the optical link 32.Link 32 can be used as the full duplex coupling between the terminal network element of link separately.
With reference to Fig. 2 a and 2b, illustrate schematic block diagram there according to an example of the antenna terminal of some aspects of the present invention and base station terminal circuit.As previously discussed, when link 32 is optical link, antenna 20 (see figure 1)s can comprise antenna terminal, be referred to as microwave remote unit (MRU) 100 (in Fig. 2 a illustrated) in this article, and BTS-A16 can comprise base station terminal, is referred to as microwave donor unit (MDU) 200 (in Fig. 2 b illustrated) in this article.Each electron optics circuit that can be included in relevant network element RF signal that produce or that receive and between the optical signalling of transmission on the link 32, change back and forth of MRU100 and MDU200.May submit to according to antenna 20 and BTS-A16 although it will be appreciated that following discussion about MRU100 and MDU200, this discussion can be similarly and is applied to antenna 28 and BTS-B24 interchangeably.
With reference to Fig. 2 a, MRU100 can be used as the transducer between RF signal and the optical signalling, transmits the signal (see figure 1) between user terminal 102 and the BTS-A16 on the optical signalling link 32.MRU100 can comprise the central processing unit (CPU) 106 that comprehensive control can be provided the operating parameter (for example, the supply power voltage of components and parts or gain setting) of components and parts within MRU100.MRU100 can also comprise can be made RF antenna element 104 can receive from the RF signal of user terminal 102 and the RF signal is transferred to the duplexer 108 of user terminal 102.RF antenna element 104 can receive the uplink signal of user terminal 102 emissions and uplink signal is transferred to duplexer 108.Uplink signal can be sent to band pass filter (BPF) 110 from duplexer 108, the latter operates and refuses the signal of other frequency according to some embodiment in the bandwidth that is used for transmitting uplink signal (for example, 824-849 megahertz) that the operating protocol according to shared network 10 defines.The uplink signal through filtering from BPF110 is exaggerated by the low noise amplifier (LNA) 112 and second amplifier 114 that overall gain (for example, about 70 decibels) is provided for system.
According to illustrational example, second amplifier 114 can be transferred to optical launcher 116 to uplink signal as modulation signal.According to some embodiments, optical launcher 116 can comprise solid-state laser diode.As an alternative, optical launcher 116 can be other suitable electromagnetic wave transmitter of the technical known any emission ripple that can modulate and detect.Modulation can be that analog or digital modulation or their combination as technical known any kind realizes.In some embodiments, modulation can apply as technical known one or more subcarriers that are to use.Optical launcher 116 can be used power supply (PS) 118 power supplies, so that invariable substantially from the average power output of reflector.In another example, in attenuator 120 can be included in, so that further control the power of supplying with optical launcher 116 and the output of therefore controlling optical launcher 116.
In an example, optical launcher 116 can produce the coherent radiation of wavelength in about 850-1550 nanometer (nm) scope in the power bracket of about 1-500 milliwatt (mW), what its power level and wavelength easily perhaps in office as an alternative.Radiation is collimated into parallel in fact light beam by transmission collimating optics device 122.For example, if optical launcher 116 comprises laser diode, optics 122 can comprise with technical known being used for and collimates the one or more lens that the method for the light beam of dispersing usually that radiates from laser diode realizes and/or the combination of other optical element (for example optical fiber).According to an example, collimated light beam can have the divergence in about 0.5-2.5mrad scope.Collimated light beam is the MDU200 that is transferred at BTS-A16 as free space up link optics signal 123 on link 32.In this example, the power that sends of optical launcher 116 is preferably less than shining the power level that causes illeffects when the person is gone up.According to other embodiment or aspect, link 32 can comprise optical fiber, and optics 122 comprises the optics that is coupled with optical fiber.In this example, higher transmitting power is possible.
With reference to Fig. 2 b, the up link optics signal 123 of transmission can be received by MDU200 at BTS-A16 on link 32.BTS-A16 is coupled to also the MDU200 as the transducer between RF radiation and the optical radiation.MDU200 can comprise the CPU202 that comprehensive control can be provided the operating parameter of components and parts within MDU200.According to some embodiments, CPU106 and/or CPU202 can also be as the technical known supervisory signals that produces, so that monitor and/or the components and parts of control link 32.
Up link optics signal is to be received by the reception collimating optics device among the MDU200 204.Optics 204 focuses on the radiation of receiving on the optical-electrical converter 206 that radiation is converted to (RF) signal of telecommunication in MDU200.Transducer 206 can also be provided for the initial preamplifier state of RF signal.In illustrational example, the RF signal of the preposition amplification of process by isolating BPF208 filtering, amplifies by main amplifier 210 earlier then.Amplifier 210 offers BTS-A16 to output signal on circuit 212.Output signal can be sent to first network 12 through BTS-A16.
With reference to Fig. 2 b, BTS-A16 also is supplied to user terminal 102 to down link signal via link 32 again.According to some embodiments, down link signal can be in the frequency band of 869-894 megahertz, though can use available any other suitable frequency band in the communication protocol that realizes in shared network 10.Down link RF signal can be transferred to the variable attenuator 216 of adjusting the RF signal level on circuit 214, so that suitable modulation depth is offered optical launcher 218.Optical launcher 218 can be similar to optical launcher 116 among the MRU100 in fact aspect operation and realization, provide with the electromagnetic wave of one of previously described method about optical launcher 116 modulation to export.Therefore, in some embodiments, optical launcher 218 is to power with power supply 220, so that invariable substantially from the power output of reflector, and in alternate embodiment, attenuator 222 may be to provide for the power output of further controlling from optical launcher 218.
Usually be similar to transmission collimating optics device 224 collimations of the optics 122 among the MRU from the radiation of optical launcher 218.In an example, optics 224 can as previously discussed be to rely on optical launcher 218 to realize at the light beam in the about 0.5-2.5mrad scope in order to produce divergence.
Radiation from optical launcher 218 is via link 32 transmission that may be wireless optical link and/or optical fiber, as previously discussed as down link optical signalling 226.Down link optical signalling 226 is received by the reception collimating optics device among the MRU100 124 (sees Fig. 2 a).Optics 124 focuses on the radiation of receiving on the optical-electrical converter 126 among the MRU100, and the latter converts radiation to the signal of telecommunication, thereby restores the signal of telecommunication that BTS-A16 provides.According to some embodiments, optical-electrical converter 126 may be similar to optical-electrical converter 206 in fact aspect operation and the realization, and may provide preamplifier state for the signal of telecommunication of receiving.
In illustrational example, the signal of telecommunication of the preposition amplification of process that is resumed is transferred to power amplifier (PA) 130 after filter 128 filtering.In other example, filter 128 may not exist, and the preposition amplifying signal of the process that is resumed can directly be transferred to PA130.PA130 is fit to power level is brought up to the last output level that is fit to be transferred to user terminal 102.Be transferred to duplexer 108 from PA130 through amplifying signal, be transmitted into user terminal 102 from RF antenna element 104 then.
Therefore, use MRU100 and MDU200, BTS-A16 can go up and user terminal transmits the RF signal back and forth at wireless optical link (for example, link 32).

According to another embodiment, antenna 20 and 34 each can comprise the MRU100 that combines and the MDU200 of alms giver's remote unit (SDRU) that is referred to as symmetry.Remote antenna 34 can become can be transferred to via wireless optical link 36 one or more optical signallings of the antenna 20 that is positioned on the tower 22 to the RF conversion of signals of receiving from one or more user terminals.In an example, antenna 20 can use SDRU that the optical signalling of receiving is converted to the RF signal of telecommunication, and (in this example, can be non-optical link to the signal of telecommunication via link 32, for example, microwave link, coaxial cable, twisted-pair cable etc.) be sent to BTS-A16.As an alternative, antenna 20 can comprise optical delivery mouth circuit (optical pass through circuitry) and can be sent to BTS-A16 to the optical signalling of receiving from remote antenna 34 via link 32 (in this example, can be the optical link that discussed the front).
It will be appreciated that optical transceiver (for example, SDRU or MRU) can be provided like this, for example, be packaged together or the ground that coexists with antenna on the tower 22, as the example described above.Yet any components and parts of antenna 20 can be separated from antenna package 20 and provide as the separate unit that is not the part of antenna 20.For example, with reference to Fig. 2 a, RF antenna element 104 can be separated with MRU100 (SDRU that maybe can comprise MRU100 and MDU200), and can use the connected mode of coaxial cable, radio frequency (RF) link, optical fiber or any technical known other type to be connected on the MRU (or SDRU).In another example, optical antenna key element 122 can be separated, and is positioned at the place away from the remainder of circuit.Optics 122 can use any suitable connected mode to be connected on the remainder of MRU or SDRU equally.This for any remote antenna 34 that belongs to operator B and 38 and antenna 28 be real equally.
Similarly, operator B can be placed on remote antenna 38 on the tower 22 that belongs to operator A, and can remote antenna 38 be coupled on second network 14 with any way that the front is described with regard to remote antenna 34.Therefore, discuss with regard to remote antenna 34 as the front, each can comprise MRU or SDRU remote antenna 38 and/or antenna 28, remote antenna 38 can comprise MRU, and antenna 28 can comprise the optical delivery mouth that connects optical link 32, perhaps antenna 38 can comprise MRU, and BTS-B can be included in the MDU that forms optical link 39 between antenna 38 and the BTS-B24.In addition, it will be appreciated that system also can be in order to offer user terminal to the signal that comes automatic network and to work, promptly, in a similar fashion, remote antenna 34,38 can receiving optical signal, for example, via link 36, and can convert optical signalling to RF signal that user terminal is broadcasted.
