Diffuser panel 100 shown in Fig. 2 a is semicylinder (for example, semicircle prism), and having includes first surface 102 and second surface 104 flexure plane, the open and flat back side rear side 110() and layer structure 106.The outer surface of diffuser panel 100 102,104,110 may include such as metal conductive material.Second surface 104 can have ripple 108, and rear side 110 can have wave Line 112.

As described above, antenna 2,24 and diffuser panel 4,18,20,22 typically in a first direction (such as along track 8, 14 direction) on be separated from each other a selected distance (for example, 2 meters or more).The first surface 102 of panel can be constructed And it is located so that the wireless signal lobe 6,16 from antenna 2,24 is generally directed to the second direction transverse to first direction, from And they for example can cross track 8,14 from panel 4,18,20,22 and scatter, such as shown in scattered signal 12.When from antenna 2, when 24 observation, the second outer surface 104 of diffuser panel 4,18,20,22 can be behind first surface 102, but can be still Towards track 8,14.Therefore, it may not be in the transmission range of the wireless signal 6 of first surface 102.It has been found that at this Setting can be improved diffuser panel 4,18,20,22 for antenna 2,24 in corrugated 108 conductive material on second surface 104 Energy is directed across the performance of track 8,14.What is be not wishing to be bound by theory is, it is believed that this ripple 108 can reduce electromagnetism The easiness that signal is propagated on second surface 104.Ripple 108 can be aligned so that when in use, diffuser panel 4,18,20, 22 are erected at beside track, and ripple 108 is aligned transverse to diffuser panel and the detaching direction (such as vertical) of adjacent antenna.

Each of diffuser panel 4,18,20,22 all include such first surface 102, the first surface 102 towards Adjacent antenna covers it by the wireless signal 6,16 that an adjacent antenna 2,24 generates, wireless to scatter Signal 6,16.Level (such as plane) cross section of panel 4,18,20,22 can be convex (for example, they can be towards rail Road 8,12 is bent outwardly), and the vertical section of the first surface 102 of (although being not shown) these panels 4,18,20,22 (vertical profile) can be spill；The surface of second surface 104 is also such.For example, first surface 102 and Two surfaces 104 can be substantially saddle type.

The planar cross section of diffuser panel 100 can be semicircular, and layer structure 106 is set as the back from the semicircle The side in face extends straightly.The curved surface of diffuser panel 100 includes two and is at an angle of adjacent segmental arc: first surface 102 and Two surfaces 104.In Fig. 2 a, Fig. 2 b, Fig. 2 c and Fig. 2 d, the two surfaces 102,104 are disposed as the different arcs of semicylinder Section (such as two exemplary 90 ° of segmental arcs of its curvature).Each of the two surfaces 102,104 can be stretched over panel 100 entire height.In figure 2 c, the vertical section of the flexure plane of panel 100 is flat, still, as described above, this is vertical Section is also possible to spill.Vertical section mentioned herein can be related to any radius of curvature perpendicular to the semicircle and hang down Directly in the profile of its any tangent line (such as the line of the plane perpendicular to semi-circular cross-section, example are line L shown in Fig. 2 b). Semicircular radius of curvature in the plan view of diffuser panel 100 can be such as 0.5 meter to 1 meter.Although should be noted that scattering surface Plate 100 can be semicylinder, but it can also need not be cylinder, such as the semicylinder can be the one of ellipsoid body Half, or simply bend to such as wing profile.

Layer structure 106 may include plate.It can be from the edge of first surface 102 (for example, open and flat rear side 110 connects The position of the flexure plane 102,104 of semicylinder) extend.The layer structure 106 can be aligned with open and flat rear side 110 (for example, it It can be located in identical plane).

First surface 102 can be smooth.Second surface 104 can have ripple 108.As shown in Figure 2 a, these waves Line 108 can cover all second surfaces 104.In this way, directly and vertically aligned vertical section can be.Panel 100 rear side 110 also can have ripple 112.Ripple 112 on the rear side 110 of panel 100 can be set in rear side 110 In the subsequent region of first surface 102, and rear side 110 be located at the subsequent region of second surface 104 can be it is open and flat (such as it is smooth, such as without such ripple 112).Ripple 112 on the rear side 110 of panel 100 is transverse to scattering surface Plate is aligned with the detaching direction (such as vertical) of adjacent antenna.

Ripple 108,112 includes in a succession of conductive material in groove and dome shape, and this running surface can be with Reduce the size (this possibly relies on the direction of electromagnetic field) of RF electromagnetic field propagated on second surface 104, and can also be from Rear side 110(gives off far from track 8,14).Groove and protrusion can have curved or angular shape, such as they can Be sinusoidal pattern, rectangular or sawtooth groove and protrusion.Ripple 108,112 can also irregularly shape, not bright Aobvious structure plan.Ripple 108,112 may include conductive material, such as metal.Ripple 108,112, which can be set, carries theirs On the surface 104,110 of panel 100 (for example, additional corrugated component can be fixedly installed on surface), alternatively, surface 104, it 110 can be in itself undulatory, such as ripple 108,112 can be formed by cutting second surface 104.For example, Ripple 108,112 can be obtained by groove cutting surface.Ripple 108,112 can be spaced apart with determining spacing.Suitable In the case where, which is the distance between adjacent rises or adjacent grooves of ripple 108,112.For example, spacing can be with It is a quarter of the electromagnetic radiation wavelength of antenna transmitting.As shown in Figure 2 a, ripple 108,112 may include along second surface 104 vertical stripes, such as striped can be parallel with the connection between rear side 110 and second surface 104 (as shown in Figure 2 a). Ripple 108,112 can be replaced by a series of sharp shaped material or kick, this is possible.

The use of ripple 108,112 can contribute to avoid forward scattering (that is, in the propagation side with the wave from antenna 2 It is upper in the opposite direction to scatter incident electromagnetic wave.

Ripple 108,112 can scatter incident electromagnetic wave on them, such as the direction relative to ripple 108,112 It is scattered on inclined direction.However, according to their stripe direction, ripple can stop or allow EM for grazing incidence EM wave The propagation of wave.In the example shown in Fig. 2 a, it can permit and propagated on the incoming panel 100 of the plane wave from antenna 2, and It can stop propagating by ripple 108,112 from other waves passed to elsewhere in diffuser panel 100.

When from before panel 100, as shown in Figure 2 d, first surface 102 is arranged in layer structure 106 and second Between surface 104.When in use, Fig. 2 a, Fig. 2 b, diffuser panel 100 is mounted on by track 8,14 shown in Fig. 2 c and Fig. 2 d The front 102,104 on side, the semicylinder can be towards track 8,14, and rear side 110 then can be opposite therewith.Panel can be placed At the side near antenna 2 towards track 8,14 for making first surface 102 be located at panel 100.If having stratiform knot Structure 106, then it can extend from the side near antenna 2 of first surface 102.

In such configuration, layer structure 106 can be by the incoming wireless signal 6,16 thereon from such antenna 2 It is directed on first surface 102.Then, first surface 102 can guide incoming these and other nothings from antenna 2 thereon Line signal 6,16 passes through railroad track, as shown in lobe 12, to provide communication in the train navigated on track 8,14.

Although its horizontal profile (such as its planar cross section) be it is curved, the vertical section of first surface 102 can To be flat or recessed.For example, diffuser panel 100 can have at edge and lower edge on it, than it, about medium position is more Big radius of curvature.Although for example, be on rear side of panel it is open and flat, panel can have narrow waist, for example, " half an hour Time hourglass " shape (for example, the hourglass shape halved along its longitudinal axis).As will be discussed with reference to Fig. 3 b and Fig. 3 c, dissipate Penetrate the first surface 102 of panel 100 vertical section can be it is recessed, flat or convex.

In context discussed above it is understood that the diffuser panel 100 of the application can be used it is a variety of different Shape.

Fig. 3 a includes three views of such diffuser panel 300:

Elevational view,

Planar cross section view shown in A-B line (this is taken from the waist among diffuser panel) in elevational view, and

The vertical cross-section of C-D line in planar cross section view.

It should be noted that the diffuser panel 300 of Fig. 3 a has the shape different from diffuser panel 100 shown in Fig. 2 a.Fig. 3 a Shown in diffuser panel 300 have first surface 302, second surface 304 and rear side 310.The planar cross section of the diffuser panel It is triangle, as shown in planar cross section A-B.However, the vertical section that first surface 302 and second surface 304 have It is recessed.For example, the planar cross section at the top and bottom of panel 300 of diffuser panel 300 can be than it at middle part Neighbouring is also big.

Vertex edge 306 between first surface 302 and second surface 304 is shown as single line, still, the application's It will be understood that this is only schematical in context.Some planar cross sections and/or one for deviateing perfect triangle can be set The vertical cross-section changed a bit, for example, " tip edge " of planar cross section can be truncated or otherwise be bent.

Fig. 3 a illustrates only an example of panel 300.This panel can have various planar cross section shapes.For example, As shown in Figure 3b, planar cross section 320 can be triangle, such as isosceles triangle.The case where planar section is triangle Under, each tip can be arc or flat.Still as shown in Figure 3b, planar cross section can be semicircle 330(also such as Fig. 2 a To shown in 2d).For example, the triangle projective planum cross-sectional shape of panel shown in Fig. 3 a can be replaced by semicircular shape, and And the first surface 302 and second surface 304 of this panel can have the spill vertical section as described in reference Fig. 3 a and/ Or vertical section 350 or vertical section 360 described in Fig. 3 c.

As shown in Figure 3b, using triangle projective planum cross section, it may not be necessary to be isosceles triangle 320, example If it can be right angled triangle 340, wherein first surface 302 is arranged to and track 8,14 one-tenth tilt angles, second surface 304 Perpendicular to track.Also other cross-sectional shapes can be used.

Fig. 3 c shows the exemplary vertical section that can be used for first surface 302 indicated by the section C-D in Fig. 3 a.

For example, first surface 302 may include two straight planes, including first surface 302-1 and second surface 302-2 is set as forming female polygonal panel 350.For example, panel 350 can from its top and bottom it is linear inwardly by The narrow waist among panel is gradually tapered to, so that vertical section can be concavity but angled, such as 350 institute of left hand view in Fig. 3 c Show.This structure can have more than two plane to link together, to form concave structure.The angle of this concave surface, Such as the angle 332 between the top or the vertical line at bottom and first surface 302 of panel 300, it can (should less than five degree Understand, the drawings are not drawn to scale).In a kind of alternative solution, first surface 302 may include single plane 370, can be with level Line is at an angle, so that the vertical section of panel is tapered from narrow bottom to wide top, or from narrow top to width Bottom be tapered.In addition, the vertical section of the first surface 302 of panel 300 can be protrusion, such as the right side in Fig. 3 c Shown in Figure 38 0.

Each of these possible planar cross sections and vertical section can diffuser panels 300 in different forms Mode is applied in combination.For example, panel 300 can have semicircular planform cross section shown in such as Fig. 2 a, and such as Fig. 3 a institute The curved spill vertical cross-section shown.It is understood that in this configuration, therefore first surface 304 can be saddle type. In another embodiment, planar cross section can be semicircular, and vertical section is the polygon of spill.It can provide in this way Structure, wherein the top half of first surface 304 corresponds to the shape of rounding frustum, and the lower half of first surface 304 It point is its mirror image, so that the planar cross section of panel 300 is the waist of part circular but panel 300 than at the top of it or narrow base.

Fig. 4 a shows the method being directed to wireless signal in train.This method includes generating first by using antenna Wireless signal (step 402).Then, this method include made using diffuser panel the first wireless signal deviate railroad track so that Side (the step 404) of the incoming train on railroad track of first wireless signal.

The antenna of this method is antenna 2,24 as shown in Figure 1.The diffuser panel of this method is as shown in Fig. 1 or Fig. 2 a-d Diffuser panel 4,18,20,22,100,.The wireless signal of this method can by the railroad track 8,14 in Fig. 1 lobe 6, 16 show.

The deviation of first wireless signal 6,16 can guide the first wireless signal 6,16 perpendicular to railroad track 8,14, such as scheme Shown in lobe 12 in 1.

Train window can be made of glass, this may cause the acute angle formed between incoming radio signal and glass Very big loss is caused to the power transferred and/or received in place.For example, some type of glass can make with window normal into 88- 90 degree of electromagnetic radiation can hardly pass through window incidence.Therefore, (and make incidence angle close when window is farther from antenna 2 90 degree) when, power loss can be more, and receivable power is less in train 26.Use diffuser panel (such as above-mentioned system Diffuser panel 4 in system, 18,20,22,100,300), and according to the above method, subtracting for this power can be partially compensated for It is few.Foregoing glass can be a kind of glass for only a kind of polarization of electromagnetic radiation being allowed to pass through.

Fig. 4 b shows the method for assembling telecommunication system.This method, which is included in beside a section of railway track track, is arranged diffuser panel (step 406).

The diffuser panel of Fig. 4 b is the diffuser panel 4,18,20,22,100,300 according to Fig. 1 or Fig. 2 a-2d.Railroad track 8,14 and antenna 2,24 can in place, and in order to assemble telecommunication system, diffuser panel 4,18,20,22,100 must be put It sets in place.This assemble method allows to be transformed existing railroad track 8,14 to include new telecommunications as shown in Figure 1 System.

Fig. 5 a is shown in train 26 directly from the received mean power of antenna 2 and to pass through scattering as unit of dBm The example of the received mean power of scattering of panel 4,18.Here exemplary train is with Swiss Federal Railway (SBB) IC2000 Train is model.Reference axis is received mean power, and from train to antenna 2 distance.In this example, antenna 2 passes Defeated power is 25 dBm, there is 25 meters of gap between each diffuser panel, i.e., diffuser panel is positioned at 225 meters away from antenna 2 At 250 meters.The size of first diffuser panel 4 less than the second diffuser panel 18 size so that the second diffuser panel 18 can be with Less covered by the radio pocket of the first diffuser panel 4.Lateral distance between diffuser panel 4,18 and track 8 is 2m. The frequency for the signal that antenna 2 issues is 2600MHz.In the simulated experiment shown in, train window is by Flachglass corporation It makes, compartment type is SBB-IC2000.Relevant readings are carried out on the upper deck in compartment.Note that can be used The antenna and diffuser panel of other configurations.For example, antenna can be placed on away from diffuser panel 500m or farther distance.Two Antenna can be installed as face-to-face.Two back-to-back diffuser panels (or a symmetrical diffuser panel) can be installed.For example, Big diffuser panel can be placed as equidistant with two antennas, and two lesser diffuser panels are individually positioned in the two sides away from antenna 15 meters to 50 meters at, it is as shown in Figure 6 (more will be described in detail below).Such configuration can be used for avoiding apparent Dead zone (shadowing).Fig. 5 a is shown at distance of 50 meters away from antenna 2, it is received from diffuser panel 4,18 The mean power for reflecting electromagnetic radio waves is -120dBm.At 200 meters apart from antenna 2, the mean power is in exponential increase To about -60dBm.At this point, the received mean power of institute is smoothly between -50dBm and -60dBm, until away from 2 meters of antenna Distance be 250 meters.In contrast, it is directly opened from the received mean power of antenna 2 from the -60dBm at 50 meters of apart from antenna 2 Begin, the about -90dBm being exponentially reduced at 250 meters away from antenna 2.This show from 170m or more away from antenna 2 away from From the power that diffuser panel 4,18 is provided to train 26 on this frequency is more.

Figure 5b shows that in train 26 directly from the received mean power of antenna 2 and to pass through scattering as unit of dBm The example of the received mean power of scattering of panel 4,18.Reference axis is received mean power, and by antenna channels and Pass through the distance away from antenna 2 in the solution of diffuser panel.In this example, the power of transmission is 25dBm, and each There are 25 meters of gap, (only there are two scattering surfaces at 225 meters away from antenna 2 and 250 meters of distances between diffuser panel 4,18 Plate).The size of first diffuser panel 4 less than the size of the second diffuser panel 18, allow the second diffuser panel 18 less It is covered by the radio pocket of the first diffuser panel 4.For example, using the diffuser panel of Fig. 2, diffuser panel 4 The radius of semi-circular cross-section is smaller than the radius of diffuser panel 18.Lateral distance between diffuser panel 4,18 and railroad track It is 2 meters.The frequency for the signal that antenna 2 issues is 3500MHz.In this experiment, window on train is manufactured by Flachglass, train vehicle Compartment type is SBB-IC2000.Fig. 5 b is substantially similar to Fig. 5 a, but the example show tranmitting frequency be 3500MHz(and 2600MHz) power v.s. distance curve.

Figure 5b shows that at distance of 50 meters away from antenna 2, be from diffuser panel 4,18 received mean powers- 107dBm.At 200 meters apart from antenna 2, the mean power is in exponential increase to arrive about -62dBm.At this point, institute is received flat Equal power is smoothly between -65dBm and -60dBm, until being 250 meters with a distance from antenna 2.In contrast, directly from day The received mean power of line 2 is exponentially reduced to 250 away from antenna 2 since from the about -50dBm at the 50 of antenna 2 meter About -70dBm at rice.This shows the distance from the 200m or more apart from antenna 2, diffuser panel 4,18 on this frequency to The power that train 26 provides is more compared to the power directly transmitted from antenna 2.

Fig. 5 c is shown in train 26 directly to receive mean power from antenna 2,24 as unit of dBm and pass through scattering The example of the received mean power of scattering of panel 4,18,20,22.Reference axis is received mean power, and passes through antenna Distance away from antenna 2,24 in channel and the solution for passing through diffuser panel.In this example, the power of transmission is 25 dBm, There are 25 meters of gap, (only there are two scattering surfaces at 225 meters and 250 meters away from antenna 2 between each diffuser panel 4,18 Plate).The size of first diffuser panel 4 allows the less quilt of the second diffuser panel 18 less than the size of the second diffuser panel 18 The radio pocket of first diffuser panel 4 covers.Between lateral distance 8,14 between diffuser panel 4,18 and railroad track Lateral distance is 1.5 meters.The frequency for the signal that antenna 2 issues is 3500MHz.In this experiment, window on train by The manufacture of Flachglass company, compartment type are SBB-IC2000.Fig. 5 c is substantially similar to Fig. 5 b, but the example is shown Be power v.s. distance that lateral distance between diffuser panel 4,18 and railroad track 8,14 is 1.5 meters (rather than 2 meters) Curve.

Fig. 5 c is shown at distance of 50 meters away from antenna 2, from diffuser panel 4,18 received mean powers be- 109dBm.At 200 meters apart from antenna 2, the mean power is in exponential increase to arrive about -62dBm.At this point, institute is received flat Equal power is smoothly between -62dBm and -60dBm, until the distance apart from antenna 2 is 250 meters.In contrast, directly from The received mean power of antenna 2 is exponentially reduced to since-the 50dBm apart from 50 meters of of antenna 2 apart from antenna 2 - 71dBm at 250 meters.This shows the distance from the 200m or more apart from antenna 2, and diffuser panel 4,18 is in this frequency nematic The power that vehicle 26 provides is more.Compared with Fig. 5 b, the distance between track 8,14 and diffuser panel 4,18, which reduce, has following effect Fruit: directly from the received mean power of antenna 2 and between diffuser panel 4,18 received mean powers exist bigger difference, And relatively when distance is 200 meters or more, the power that diffuser panel 4,18 is transmitted to train 26 is more.

Although above-mentioned simulated experiment and measurement are carried out under given conditions (for example, having specific compartment, glass Glass type and distance), it should be appreciated that, result is generally also applicable to general railroad track and train system.Therefore, it is Uncompensation distance antenna 2 is more than the power loss at the distance of 100m, and the scattering wireless signal 12 of diffuser panel 4,18 can be helped Help increase received power in train 26.It is worth noting that, glass used in these simulated experiments is by FLACHGLAS It is supplied to passenger train.Such glass can pass through it only to allow a kind of polarization mode of wireless signal, but other The glass of type also can permit a variety of polarization types and pass through.

Fig. 6 shows another example of the telecommunication system for being directed to electromagnetic signal in train.Train can be at it Two tracks 8,14 of upper traveling are located in parallel to one another.The first side of track 8,14 is arranged in two communication antennas 2,3, in addition The other side of track 8,14 is arranged in two communication antennas 24,25.The system further includes first that two tracks 8,14 are arranged in A biggish diffuser panel 32 and two lesser diffuser panels 34,36 on side, and the other side of track 8,14 is set On a biggish diffuser panel 42 and two lesser diffuser panels 44,46.Diffuser panel 3234,36,42,44,46 and day Line 2,24 is located at beside railroad track, and is spaced a distance with railroad track, and the distance is for example between about 0.5 meter and about 10 meters Between, for another example between 1 meter and 5 meters, for another example between 2 meters to 4 meters；Such as between 1 meter to 3 meters, or Between 3 meters to 6 meters.

Larger diffuser panel 32 on first side of track 8,14 is equidistantly disposed between antenna 2,3, and larger scattered It penetrates between the antenna 24,25 that panel 42 is equidistantly disposed on the other side of track.Lesser diffuser panel 34,36,44,46 is set It sets at biggish diffuser panel 32,42 equal distance d, which is arranged in the corresponding of track 8,14 Side.

Diffuser panel 32,34,36,42,44,46 respectively includes conductive surface, which is positioned at least one The incident wireless signal divided draws guide rail 8,14.For example, each of diffuser panel 32,34,36,42,44,46 can be as It is configured with reference to described in Fig. 2 a-2d, Fig. 3 a-3c and Fig. 8 a-8d herein.Diffuser panel can be configured to/ It is positioned so that biggish diffuser panel 32,42 also guides wireless signal into lesser diffuser panel 34,36,44,46, then will Signal guides track 8,14 into.

The distance between the larger smaller diffuser panel 34,36,44,46 corresponding with them of diffuser panel 32,42 d can be 15m is between 50m.This set can be to avoid apparent dead zone.

Referring to Fig. 1 and Fig. 2, it is clear that a series of variations can be provided.Can also provide above system further improvement and Advantage.

For example, the ripple 112 on the rear side 110 of diffuser panel 100 as described herein is that optional or rear side 110 can To be covered partially or completely by ripple 112.Layer structure 106 can be used for ELECTROMAGNETIC RADIATION REFLECTION to the first layer surface 102 On, to increase the amount of radiation guided by diffuser panel 100 towards railroad track 8,14.For example, when diffuser panel 100 is mounted on iron When rail road 8,14 side, layer structure 106 can simultaneously directional antenna 2, and its open and flat surface parallel with railroad track 8,14 Towards track 8,14.Layer structure is optional feature for diffuser panel.

For example, with reference to Fig. 1, antenna 2,24 is located at the opposite side of two section of railway track tracks 8,14.First antenna 2 is located at first segment 8 side of railroad track, the second antenna 24 are located at 14 side of second segment railroad track.

Fig. 1 shows train 26 and is located on first segment railroad track 8, adjacent with one in the first diffuser panel 4.Antenna 2,24 for generating wireless signal 6,16.First antenna 2 positioned at 8 side of first segment railroad track can produce wireless signal 6, from And wireless signal 6 is roughly parallel to the traveling of first segment railroad track 8, until wireless signal 6 reaches diffuser panel 4.Diffuser panel 4 Wireless signal 6 is scattered, so that wireless signal 12 is guided the side of incoming train 26.

The second antenna 24 on 14 side of railroad track generates the second lobe 16 for being shown as wireless signal, but it is straight It connects and guides train 26 into, rather than towards diffuser panel 22.Then, two independent signals can be provided for train 26, in this way may be used To realize MIMO(multiple-input and multiple-output) system.

It is understood that the system of claim 1 may include any in the diffuser panel 100,300 of Fig. 2 and Fig. 3 One.The system of Fig. 1 can produce the transmission result of Fig. 5.In addition, the system that Fig. 1 can be used in the method according to Fig. 4 a, and The system can be assembled according to the method for Fig. 4 b.The system of Fig. 1 can be included in optional feature below.

The antenna 2,24 of Fig. 1 can be the communication antenna for generating wireless signal 6,16.Antenna 2,24 can be dipole Antenna, loop aerial, helical antenna, array antenna or any other type for generating wireless signal antenna.Antenna 2, 24 can be also used for receiving wireless signal.In some cases, this will realize the two-way between antenna 2,24 and another equipment Letter, so that antenna 2,24 is generated by the received wireless signal 6,16 of another equipment, then another equipment generation is connect by antenna 2,24 The signal of receipts.Another equipment can be located on train 26.

It should be noted that diffuser panel 4,18,20,22 need not be arranged in pairs, on the contrary, can provide list in some instances A diffuser panel 4.Diffuser panel 4,18,20,22 can be set on every side of two section of railway track tracks 8,14, but they It can be offset from one another on the direction that track 8,14 extends and on the direction of the extending direction perpendicular to track 8,14, so that Diffuser panel 4,18,20,22 is staggered.

The quantity that 8,14 sections of railroad track is merely illustrative, can provide the track of any other quantity.Track 8, 14 be optional, and system can be used as the offer of the external member including the antenna 2,24 for being mounted on rail side.If there is Track 8,14, then it can be powered or no power.Track 8,14 can be used for underground railway, ground railway or any other type Railway.Track 8,14 may not necessarily be made of physical track, and can be the space that train can advance by it, such as in institute In the case where " magnetic suspension train " of meaning, track includes the channel that train suspends above it.The system can be also used for other Public transportation system, such as electric car or bus.

Fig. 1, which shows diffuser panel 4,18,20,22, to be located on mast 10.Diffuser panel 4,18,20,22 can be with It is freestanding.If diffuser panel 4,18,20,22 is attached to mast 10, mast 10 be can be for providing electric power To provide the stretched wire shape mast (catenary masts) of power for electric train.In addition, antenna 2,24 is again shown as connecting To mast 10, but they be also possible to it is freestanding.Diffuser panel 4,18,20,22 is attached to mast 10, or will be dissipated The setting of panel 4,18,20,22 is penetrated in self-supporting position, system modification shown in FIG. 1 can be made to be applied to existing rail Road 8,14.

Fig. 1 shows the train 26 on track 8,14, it will be appreciated, however, by one skilled in the art that the effect of train be along Track 8,14 is advanced, therefore, not always with the presence of train on two sections of tracks 8,14, and in this case, wireless signal 12 can be guided through railroad track 8,14 instead.
