Embodiment

Many portable electric appts can both carry out radio communication.In recent years, the quantity can carrying out the equipment of radio communication sharply increases, and such equipment is used more and more widely.Radio communication equipment can carry out radio communication and receive radio communication in one or more frequency band.If particular device is not configured/is fabricated to use another frequency band, then this equipment possibly cannot use in this special frequency band.4G communication equipment becomes more and more general, and they require that multiple LTE time slot (frequency band) carries out receiving and transmitting.4G equipment may require to access nearly 14 different time slots (frequency band) can use all over the world, and the time slot allowed in different location and frequency band different.

After communication equipment has been manufactured to and operates in different frequency bands, one or more frequency band may be made available.If it is not originally manufactured to and uses these new available band, then communication equipment possibly cannot use them.Such as, its operational " newly " frequency band can be made to comprise idle television band, Landsat band, blank frequency band or cognitive radio strategy frequency band.If particular communication devices move to from a position different frequency bands can another position, such as when equipment be transferred to another country and the operator of this country use different from former country frequency band, then " newly " frequency band can supply this equipment use.Such as, may be such situation when using dummy frequencies to carry out radio communication, wherein different frequency bands be put into use according to the position of communication equipment and which blank frequency band and have become available.

Local statues may forbid special frequency band to be used for communication, and therefore may there is restriction for special frequency band for the public of radio communication.Such as, in particular locality, one or more frequency band may be retained for emergency services communications (police, ambulance, fire service), or used by other service/industry of such as railway, oil exploitation and traffic system and so on.These frequency bands of using by special services/industry may not be allowed to be used by general public.

And, may expect that available communication devices is able to easily be changed to use together with special frequency band (such as, police radio communication band), even if this communication equipment is not designed/is fabricated to use like this originally.Such as, by this way, police officer may use the mobile phone of police radio frequency band to come together to use with those police radio frequency bands by not originally being configured to.

In addition, when some when urgent or distance sensor, may be desirably in the communication equipment using in lower band (such as 700MHz or 400MHz) and use for high frequency band (such as 2.4GHz Wi-Fi, 2.4GHz bluetooth, 2.4GHz Zigbee and 1.8GHz GSM), this can allow communication distance to extend to some extent.

It can be favourable for can making can carry out operation in other frequency band one or more now for the communication equipment carrying out operating in one or more special frequency band.In addition, it can be favourable for can preventing equipment from one or more specific " forbidding " frequency band, carrying out communication.

Can when carry out without the need to the RF parts to this equipment, hardware and/or software obviously material alterations or amendment change communication equipment the frequency band that can operate with it can be favourable.In addition, if the change of this operational frequency bands for equipment can easily reverse, can be favourable.Such as, existing or " tradition (legacy) " equipment is carried out changing so that in a new condition (that is, using the frequency band of to expect that with this equipment those frequency bands of using are different at first) carries out operating and do not carry out change to the hardware of this equipment or software can be favourable.

Following one or more examples can be considered to provide the solution for problem described above.

Fig. 1 a shows network 100, and it comprises portable radio communication equipment 102 and two far-ends 106,110.In this example, equipment 102 does not have radio shielding annex.Equipment 102 can communicate with the first far-end 106 in the first frequency band 108, and communicates with the second far-end 110 in the second frequency band 112.This first frequency band can be such as this second frequency band of GSM 800 frequency band can be such as then Wi-Fi 2.4GHz frequency band.

Fig. 1 b shows different networks 150, and it comprises the identical portable communication device 102 be within radio shielding annex (such as, lid) 152, and three far-ends 106,110,160.Identical with Fig. 1, equipment 102 can communicate with the first far-end 106 in the first frequency band 108.

With network 100 unlike, in the network 150 of Fig. 1 b, equipment 102 is prohibited from using the second frequency band 112 and communicates with far-end 110.Second frequency band 112 such as can be retained for local police, or it may be the blank frequency band for other user retains.Under any circumstance, equipment 102 should not use the second frequency band 112 to carry out external telecommunication, operates even if equipment 102 is configured to use second frequency band 112.

In addition, with network 100 unlike, in the network 150 of Fig. 1 b, there is the 3rd available far-end 106, the 3rd frequency band 162 can be used to communicate with it.But equipment 102 is not configured to be used alone the 3rd frequency band 162.

Therefore, the equipment 102 in Fig. 1 b is equipped with radio shielding annex 152, and it is illustrated schematically in the exterior circumferential of equipment 102.Radio shielding annex 152 for portable radio communication equipment 102 be configured to stem from portable radio communication equipment 102, radio communication on the radio bands of this portable radio communication equipment shields, described radio bands is forbidden second frequency band 112 in this case.

As specifically discussed subsequently, radio shielding annex 152 comprises inwardly wireless radio coupler, outwards wireless wireless aerial and radio frequency transducer.The parts 154 of annex 152 are shown schematically as and illustrate frequency band conversion and radio communication shielding.

Therefore, even if equipment 102 cannot receive radio communication from the 3rd far-end 160 because the 3rd frequency band 152 itself not being configured to use the 3rd far-end 160 carries out operating separately and transmit radio communication to the 3rd far-end 160, but radio shielding annex 152 can allow equipment 102 effectively to show as can receive radio communication from the 3rd far-end 160 just as it and transmit radio communication to the 3rd far-end 160 the same.Annex 152 also serves as and prevents radio communication on forbidden second frequency band 112 by the radio shielding of teletransmission.

Due to radio frequency transducer and the inwardly wireless radio coupler of annex 152, this annex 152 can carry out radio communication with Portable Radio Communication 102 by the second radio bands 112 in this locality with portable radio communication equipment 102 conductively-closed.Therefore, the radio communication from the 3rd far-end 160 can be changed by annex 152 between the 3rd received frequency band 162 and the second radio bands 112 of equipment 102 conductively-closed, and in this locality, they is sent to equipment.By this way, equipment 102 frequency band 162 distally 160 received communications that its (when not having radio shielding annex 152) can be used to receive separately.

Due to this radio frequency transducer and outwards wireless wireless aerial, this annex 152 can allow equipment 102 to use the 3rd radio bands 162 and the 3rd far-end 160 to carry out remote radio communication.Therefore, radio communication can be changed by annex 152 between second radio bands 112 and the 3rd frequency band 162 of conductively-closed, and they are sent to annex 152 from equipment 102 this locality, and make annex 152 that the 3rd radio bands 162 can be used to transmit radio communication to the 3rd far-end 160.By this way, the frequency band that equipment 102 can use its (when not having radio shielding annex 152) cannot be used for separately carrying out transmitting distally 160 transmits communication.

This radio shielding annex can also to stem from or can stem from portable radio communication equipment 102, radio communication on the frequency band 112 of conductively-closed shields/forbids, prevents the transmission carrying out being prohibited/shielding on the second frequency band 112 thus.

This radio shielding annex can be used as shielding bubble (shield bubble) around portable radio communication equipment effectively.Stem from portable radio communication equipment, radio communication on the radio bands of this portable radio communication equipment, by this annex utilize by shielding the bubble that creates shield (radio bands of this equipment can be considered to this bubble the screening frequencies forbidden).But even if its conductively-closed, this equipment still can use the radio bands of this equipment send and receive radio communication by using radio frequency conversion.This is because, via the radio frequency conversion (this conversion is performed by the transducer of radio shielding annex) to device frequency, inwardly wireless radio coupler allows to arrive this equipment from aerial that receive, not on this device frequency radio communication by " bubble ".Advantageously, near field communication can be used.Same use radio frequency transducer, outwards wireless wireless aerial allow from this equipment, radio communication on the device frequency of conductively-closed arrived in the air by " bubble ", but now this conversion is from the device frequency of conductively-closed to different frequency.This outwards wireless wireless aerial advantageously allows wireless far-field communication.

Usually, the radio coupler that this is inwardly wireless should be placed by the inner side towards this radio shielding annex, and it can be inwardly coupled with the suitable antenna of the equipment used with this annex.The radio coupler that this is inwardly wireless not necessarily needs the inside being placed in radio shielding annex.This relates to the communication of inwardly going to equipment from this annex to intercoupler.

From outwards wireless wireless aerial transmission not should shield by this radio shielding annex, and therefore can be placed in non-masking position to outside antenna, such as, towards the outside of this radio shielding annex.Similarly, will appreciate that, this outwards wireless wireless aerial not necessarily needs the outside being placed in this radio shielding annex.This relates to outside antenna the equipment of leaving and outwards goes to aerial communication from this annex.

This can be formed by superficial layer or track (track) to intercoupler and/or to outside antenna, but in order to the Long-Time Service of optimum, they are by within the layer that is structured in APPENDIX MATERIALSThe best or sublayer, to make this coupler/antenna minimize because material corrosion and/or user dispose the hydraulic performance decline caused.

This radio shielding annex can online (namely real-time) carry out changing and changing from different frequency bands to different frequency bands.In addition, to be allowed to and equipment self is configured to use its frequency band carrying out operating still can be used, to be such as used for the first frequency band 108 carrying out with the first far-end 106 communicating.

In addition, due to radio shielding annex 152 by the wireless coupling to equipment converted band prevent forbidden transmission, so substantially do not need self to change equipment 102 or change.If the user of equipment 102 does not wish the transmission changed any frequency band or prevent on special frequency band, then can simply this radio shielding annex be removed from equipment 102, or can be closed simply (such as, when using minimum shielding cladding material and use signal suppressing to prevent the transmission in conductively-closed frequency band).

And be envisioned that, different radio screening accessory 152 can be suitable at different conditions (such as, at diverse location) and use.Therefore, the ability of frequency that easily conversion equipment 102 can use can be achieved for the radio shielding annex 152 of this equipment by changing according to specified conditions simply.Use different radio screening accessory 152 can be a kind of option for different frequency conversion/shielding requirements, wherein compared with can performing the single radio screening accessory of all conversion/shieldings, each radio shielding annex 152 can relatively easily and/or more at an easy rate carry out manufacturing (although also can provide the radio shielding annex that can perform all conversion/shieldings).Example as described herein allows the flexibility of the difference/whole frequency inverted/shielding option required according to user.

Fig. 2 schematically illustrates the radio shielding annex 200 of example, it is designed to cover on the existing lid of communication equipment, comprises flexible coating 202, hardware circuit 204 (it such as can comprise component software, processor and/or memory), the battery 206 being connected to hardware circuit, inwardly wireless radio coupler 210 and outwards wireless wireless aerial 212.Flexible coating 202 allows user to be dragged on their device by annex 200 easily to carry out attachment cooperation.Coating 202 can comprise non-flexible position, such as metallic shield assembly and/or battery 206.In some instances, annex 200 comprises all parts of coating 202, hardware 204 and battery 206 can be flexible.

In other example, radio shielding annex 200 can be the paster of the outer cover body being configured to be attached to portable radio communication equipment, or can be the replacement outer cover body of portable radio communication equipment.

In the figure 2 example, radio shielding annex 200 comprises battery 206, and it is configured to provide electric power to power to one or more in transceiver, transducer and shielding to radio shielding annex 200.In other example, this radio shielding annex can be configured to be undertaken powering to provide electric power to radio shielding annex by the internal electric source of portable radio communication equipment (instead of the battery of annex self or the battery together with annex self) and power to one or more in transceiver, transducer and shielding.Annex comprises battery and makes not use/require the battery/power source of equipment to carry out power supply to annex can be favourable.

In other cases, annex carries out power supply by the battery/power source of equipment can be favourable; Such as, when not having special battery/power source (but the suitable wire/wireless coupling that may have to device battery/power supply), the manufacture of annex can be more easy and cheap.

Fig. 3 a-3b illustrates the radio shielding annex lid 302 above communication equipment 304 from front (Fig. 3 a) and side (in Fig. 3 b).

The exemplary position of the inside and outside radio transceiver of this annex is illustrated in the top area 306 of radio shielding annex 302, left side and right side area 308,310, and bottom section 312.Such transceiver should be located thus be obtained and be received from aerial good radiated communications, allows to carry out good radiated communications transmission to equipment, and concrete absorptivity (SAR) is minimized.

Fig. 4 a-4b illustrates the radio shielding annex lid 402 above communication equipment 404 from front (Fig. 4 a) and side (in Fig. 4 b), there is illustrated five antenna/transceiver of radio shielding annex 402.

In fig .4, top area 406 shows top (front) antenna 416, and left side and right side area 408,410 respectively illustrate left side and right side antenna 418,420, and bottom section 412 then shows bottom antenna 422.See from the end view Fig. 4 b, back side antenna 430 and top face antenna 416 are illustrated among the top area 406 of radio shielding annex 402.

In some instances, inside radio frequency coupler and the outside radio frequency antenna same radio frequency transceiver that can share some or all to operate in the radio bands and the second different radio bands of conductively-closed.That is.This inside radio frequency coupler and outside radio frequency antenna can be same parts, or this inside radio frequency coupler and outside radio frequency antenna share certain or some parts.In some instances, inside radio frequency coupler and outside radio frequency antenna can be identical transceivers.Go out as shown in figure 4 a-4b, more than one antenna/transceiver 416,418,420,422,430 can be had in radio shielding annex 402.

Radio shielding annex as described herein can be configured to the radio bands of the conductively-closed in identical radio communication classification and the second different radio bands operates.Such as, this equipment can self be configured at blank frequency band f ₁, f ₂and f ₃operate, but under specific circumstances, may can use blank frequency band f ₄and blank frequency band f ₁then may be prohibited for equipment.In this example, all four frequency band f ₁, f ₂, f ₃and f ₄it is all dummy frequencies.In other example, can access and/or forbid different classes of communication band.

Fig. 5 a and 5b to schematically illustrate in the cap portion/masked segment that may be present in radio shielding annex of the present disclosure and can be used as the different layers of radiation shield/absorber.
