When wireless relay module and MiFi module are integrated in same circuit board; Because each electronic circuit module of wireless relay module and MiFi module all adopts close electronic devices and components to realize; And the required operating voltage of electronic devices and components work be usually several frequently seen voltage (as+12V ,+5V ,+3.3V ,+1.8V etc.); The required operating voltage type height of the two each electronic circuit module work overlaps; Therefore for reducing the realization cost of power module; Reduce the area of shared circuit board; Can adopt 1 power module (follow-up can being called " the total module of power supply ") to replace first power module and second source module, but the voltage type of the total module output of power supply must comprise the type sum of first power module and second source module output voltage, and the peak power output of the total module of suggestion power supply is not less than the peak power output sum of first power module and second source module.Such as first power module exportable+12V ,+3.3V ,+1.8V, peak power output are 10W; The second source module is exportable+12V ,+5V ,+1.8V, peak power output are 30W; Then the total module of power supply must be exportable+12V ,+5V ,+3.3V ,+1.8V, peak power output is 40W.
Because retransmitting antenna is with the deployed position that inserts antenna and towards consistent (all aiming at the terminal use) in the practical application; Therefore for reducing number of antennas, reduce equipment cost, improving device integration, can consider to retransmit communication module and WLAN AP module through mixer (it is different to retransmit the used WLAN standard frequency range of the used mobile standard frequency range of communication module work and the work of WLAN AP module usually) shared one group of antenna (all frequency ranges of frequency range covering retransmitting antenna and access antenna); In like manner, because donor antenna and passback antenna be all towards donor base station, so alms giver's communication module and terminal communication module also can be passed through the shared one group of antenna of mixer.Whether the mode of common antenna and retransmitting antenna and the number of antennas that inserts antenna (or donor antenna and passback antenna) identical has relation, specifically:
When retransmitting antenna was identical with the number that inserts antenna (or donor antenna and passback antenna): (number of antenna can equate with the number of retransmitting antenna or access antenna in first antenna sets for shared first antenna sets to retransmit communication module and WLAN AP module; Be that retransmitting antenna is all shared with the antenna that inserts antenna; Certainly; Also can have only the part antenna to adopt antenna duplexer in the antenna of retransmitting antenna and access antenna; Other antennas still adopt stand-alone antenna), equate to be example with number of antenna in first antenna sets with the number of retransmitting antenna or access antenna, need to introduce the mixer that equates with the number of antenna of first antenna sets; The public port of each mixer links to each other with 1 antenna in first antenna sets, and other 2 ports of each mixer link to each other with a transceiver channel retransmitting communication module and WLAN AP module respectively; In like manner; Alms giver's communication module and terminal communication module are for shared second antenna sets (equating to be example with the number of donor antenna or passback antenna with number of antenna in second antenna sets); Need to introduce the mixer that equates with the number of antenna of second antenna sets; The public port of each mixer links to each other with 1 antenna in second antenna sets, and other 2 ports of each mixer link to each other with a transceiver channel of alms giver's communication module and terminal communication module respectively.
Retransmitting antenna and the number that inserts antenna (or donor antenna and passback antenna) be not simultaneously: when retransmitting shared first antenna sets of communication module and WLAN AP module, can introduce the mixer common sparing antenna of less number of antennas in retransmitting antenna and the access antenna; Be 2, insert number of antennas to be 3 such as the retransmitting antenna number; And retransmitting antenna and access antenna frequency range are not simultaneously; Then can introduce 2 mixers; Retransmit communication module and WLAN AP module through 2 shared 2 antennas of mixer (these 2 antenna frequency ranges must be supported retransmitting antenna frequency range and all frequency ranges that insert antenna), the 3rd antenna only need support that inserting the antenna frequency range gets final product.In like manner, during shared second antenna sets of alms giver's communication module and terminal communication module, can introduce the mixer common sparing antenna of less number of antennas in donor antenna and the passback antenna.
Power module is shared; And the dual-mode device of retransmitting communication module and shared first antenna sets of WLAN AP module, alms giver's communication module and shared second antenna sets of terminal communication module can be as shown in Figure 5; This dual-mode device comprises first antenna sets 16 of retransmitting communication module 11, alms giver's communication module 12, WLAN access node WLAN AP module 13, terminal communication module 14, power module 15, communicating with the terminal; Second antenna sets 17 and the mixer 20 that communicate with the base station, wherein:
And when repeating transmission communication module 11 is identical with WLAN AP module 13 working frequency range, can adopt same frequency combiner with the mixer that WLAN AP module 13 links to each other with repeating transmission communication module 11; Retransmit communication module 11 and WLAN AP module 13 working frequency range not simultaneously, this mixer can adopt the alien frequencies mixer.
Equally, when alms giver's communication module 12 was identical with terminal communication module 14 working frequency range, the mixer that links to each other with terminal communication module 14 with alms giver's communication module 12 can adopt same frequency combiner; Alms giver's communication module 12 and terminal communication module 14 working frequency range not simultaneously, this mixer can adopt the alien frequencies mixer.
The inventor further analyzes the back and finds; If alms giver's communication module and terminal communication module and identical mobile standard base station communication, used working frequency range is identical or be separated by when not far, the part of alms giver's communication module and terminal communication module even all circuit maybe be shared then.The shared degree of alms giver's communication module and terminal communication modular circuit is relevant with the wireless relay type of module; Below to two kinds of typical wireless relay modules (each a kind of analog type and numeric type); Further propose the dual-mode device of following 2 kinds of common source modules, antenna and partial circuits, introduce respectively below.
The wireless relay module is an analog type, promptly the wireless relay module only analog domain radiofrequency signal is carried out filtering, amplification in addition on down-converted, the radiofrequency signal forwarding after will handling then.Because the terminal communication module not only comprises the analog domain processing and also comprises the numeric field processing; This moment the alms giver communication module with the terminal communication module can consider the common analog territory circuit (working frequency range be more or less the same and circuit function similar; Can be shared a cover Realization of Analog Circuit), the terminal communication module also needs independently numeric field circuit.At this moment; To dual-mode device as shown in Figure 5; Said terminal communication module 14 may further include terminal communication analog circuit submodule 141 and terminal communication digital circuit submodule 142; Terminal communication analog circuit submodule 141 is shared through passback analog module 18 with alms giver's communication module 12, and passback analog module 18 is connected with second antenna sets 17, and terminal communication digital circuit submodule 142 is connected with WLAN AP module 13, passback analog module 18 respectively.The dual-mode terminal structure of this moment can be as shown in Figure 6.
Wherein, Passback analog module 18 is being retransmitted between the communication module 11/ terminal communication digital circuit submodule 142 and second antenna sets 17; During downlink communication; Passback analog module 18 receives the radiofrequency signal that moves the standard base station from second antenna sets 17, and to filtering and processing and amplifying that radiofrequency signal is simulated, the signal after will handling is then given respectively and retransmitted communication module 11 and terminal communication digital circuit submodule 142; During uplink communication; Passback analog module 18 is from retransmitting the upward signal that communication module 11 and terminal communication digital circuit submodule 142 receive after handling; And to filtering and processing and amplifying that signal is simulated, the radiofrequency signal after will handling is then given second antenna sets 17; Transceiver channel number in the passback analog module 18 and alms giver's communication module 12 and more the equating of terminal communication analog circuit submodule 141 transceiver channel numbers; Less the equating of transceiver channel number in shared transceiver channel number and alms giver's communication module 12 and the terminal communication analog circuit submodule 141, and shared transceiver channel working frequency range must be contained all working frequency range of alms giver's communication module 12 and terminal communication analog circuit submodule 141; Have 2 transceiver channels and adopt the 1800MHz frequency range such as alms giver's communication module 12; Terminal communication analog circuit submodule 141 has 4 transceiver channels and adopts the 2.6GHz frequency range; The transceiver channel number that then returns analog module 18 is 4; Shared transceiver channel number is 2, and the frequency range of 2 shared transceiver channels must support 1800MHz frequency range and 2.6GHz frequency range, and 2 not shared transceiver channels only need support that the 2.6G frequency range gets final product;
Terminal communication digital circuit submodule 142 is between WLAN AP module 13 and passback analog module 18; During downlink communication; The analog signal that terminal communication digital circuit submodule 142 receives after handling from passback analog module 18; And analog signal carried out down-conversion, analog-to-digital conversion, and digital processing such as demodulation, decoding, the signal after will handling is then given WLAN AP module 13; During uplink communication; The upward signal that terminal communication digital circuit submodule 142 receives after handling from WLAN AP module 13; And to signal encode, digital processing such as modulation, and processing such as digital-to-analogue conversion, up-conversion, the radiofrequency signal after will handling is then given and is returned analog module 18;
First antenna sets 16 is positioned at mobile standard/WLAN standard terminal and retransmits between the communication module 11/WLANAP module 13; To retransmit the radiofrequency signal that communication module 11/WLAN AP module 13 handles well during downlink communication and be converted into electromagnetic wave, and send to and move standard terminal and WLAN standard terminal; To move the electromagnetic wave signal of launching in standard terminal and WLAN standard terminal during uplink communication is converted into radiofrequency signal and gives and retransmit communication module 11/WLAN AP module 13 and handle; The number of antennas of first antenna sets 16 can be more than 1, and such as being support MIMO technology, first antenna sets 16 can have many antennas.The number of antenna of first antenna sets 16 is for retransmitting communication module 11 and the higher value of WLAN AP module 13 with the required number of antennas of terminal communication; Retransmit communication module 11 and be the smaller value of repeating transmission communication module 11 with the required number of antennas of WLAN AP module 13 work with WLAN AP module 13 shared number of antennas; And the working frequency range that the two shared every antenna is supported covers the used frequency range of WLAN AP module 13 and the terminal communication of WLAN standard and retransmits communication module 11 and the used frequency range of mobile standard terminal communication, and every not shared antenna only need support self frequency range to get final product; Need 3 antennas and adopt the 2.4G frequency range such as WLAN AP module 13; Retransmitting communication module 11 needs 2 antennas and adopts the 900MHz frequency range; Then the number of antenna of first antenna sets 16 is 3; Shared number of antenna is 2, and 2 shared antenna frequency ranges must support 2.4G frequency range and 900MHz frequency range, and that not shared root antenna only need support that the 2.4G frequency range gets final product;
Second antenna sets 17 will return the radiofrequency signal that analog module 18 handles well and be converted into electromagnetic wave between mobile standard base station and passback analog module 18 during uplink communication, send to mobile standard base station (donor base station); To move electromagnetic wave signal that standard base station (donor base station) antenna launches during downlink communication is converted into radiofrequency signal and gives passback analog module 18 and handle; The number of antennas of second antenna sets 17 can be more than 1, and such as being support MIMO technology, second antenna sets 17 can have many antennas.The number of antenna of second antenna sets 17 equates with the transceiver channel number of passback in the analog module 18, and each the root antenna in second antenna sets 17 all with return analog module 18 in transceiver channel corresponding one by one; The every antenna that links to each other with shared transceiver channel, its working frequency range must cover alms giver's communication module 12 frequency range and the terminal communication analog circuit submodule 141 and mobile standard base station communication used frequency range used with mobile standard base station communication; The every antenna that links to each other with common transmit-receive passage not, its working frequency range only need support self frequency range to get final product;
Retransmit the required number of antennas of communication module 11/WLAN AP module 13 work when identical; Retransmit communication module 11/WLAN AP module 13 for shared first antenna sets 16 (being all example mutually with the required number of antennas of repeating transmission communication module 11 work) with number of antennas in first antenna sets 16; Need to introduce the mixer 20 that equates with the number of antenna of first antenna sets 16; The public port of each mixer 20 links to each other with 1 antenna in first antenna sets 16, and other 2 ports of each mixer 20 link to each other with a transceiver channel retransmitting communication module 11 and WLAN AP module 13 respectively;
