Description

The invention relates to a transceiver arrangement for a passenger cabin having head sides, side walls, rows of seats and a passage. The transceiver arrangement has first transceivers and second transceivers, which are designed for wireless data transmission with one another. The first transceivers have a coverage area. The combined transceivers (transceivers, of English transmit, receive) are arranged such that the second transceivers are detected by more than one coverage area of the first transceivers, the second transceivers being contained in seats arranged in rows of seats. Moreover, the invention relates to a communication device for such a passenger cabin, a passenger cabin and an aircraft, which are provided with such a transceiver.

In recent years, new passenger amenities have been added to enhance comfort in passenger cabins. This ranges from several selectable radio programs from the armrest to Internet access via a screen integrated in the seat. It is also known to offer a board library from which passengers can select music, videos and games.

The provision of this media data often requires a high data bandwidth for transmission. Currently, the data connections are realized, for example, by a star-shaped wiring, in which a network cable is routed to each seat from a central distributor. It is also known to build a stepped wiring with manifolds that supply only a few seats. In this case, it is necessary to equip the supply line to the manifolds with high data rates, so that the service quality does not suffer. With poor quality of service could result in a noticeable jerking or dropouts in the sound and image for the passengers.

The star-shaped wiring has the disadvantage, in particular in aircraft, that the laid cables give the passenger cabin a considerably increased weight.

Furthermore, it should be noted that in particular a star-shaped network topology has a large space requirement, since the star-shaped cables converge at the central distributors and a cable duct of appropriate size must be provided.

To reduce the number and length of cables needed, the DE 695 34 117 T2 a multi-level distribution system. Audio and video signals to be distributed to display devices in individual aircraft seats are routed via a bus to area management units which copy the signals from the bus and forward them to seat units, for example, each providing several seats with the audio and video signals. Particular attention is paid to the fact that the signals, when removed from the bus, are attenuated to different extents depending on the distance from the entry point. Accordingly, the gain of different amplifier units is adjusted to achieve improved signal quality.

Against this background, it is desirable to replace the cable connections in passenger cabins by wireless data transmission. The presently widespread wireless networks, however, have the disadvantage that the data rate in a network segment is limited and, for example, insufficient for the transmission of multiple video streams. The wireless transmission systems, which have sufficient bandwidth, all use higher, sometimes much higher, frequencies than the conventional wireless networks.

The US 2004/0098745 A1 therefore proposes to divide an aircraft cabin into smaller network segments, in each of which the full bandwidth of a network segment is available. In addition, the network segments that are provided by different access points, overlap in their spatial extent, so that in case of failure of an access point whose functions are taken over by neighboring access points.

Particularly in the case of aircraft, the frequency bands which can be used in the passenger cabin are very heavily regulated. At the very high frequencies that can be used, further effects are noticeable, which can influence the network topology. On the one hand, the signal attenuation is very high at such high frequencies. Furthermore, reflection on the walls of the passenger cabin results in multi-path effects. Electromagnetic radiation also behaves quasi-optically in these frequency ranges, so that persons and objects located between transmitter and receiver can cause a significant shadowing of the connection signal and thus a loss of data bandwidth up to complete interruption.

The invention is based on the task of increasing the quality of service of the wireless data transmission in such a high-bandwidth wireless network.

To solve this problem is proposed according to claim 1 that is arranged in a row of seats in only a second transceiver, seats of a row of seats, which have no second transceiver, are connected by means of a wired connection to the second transceiver of these rows of seats.

The fact that only a second transceiver is provided in each row of seats, the maintenance is reduced. Furthermore, a simple signal routing to the other seats of each row can be realized easily.

This means that the second transceivers have more than one communication partner through which they can handle a data transfer. Thus, if a transmission path, for example, by people walking around, covered, so the data transmission by means of the second transmission path can still be performed. This reduces the number of cases in which the data transmission stops and thus losses in service quality can be accepted.

In a further embodiment, the passage may be a passage and the rows of seats extend between the passage and the side walls. At one aisle seat of each of the rows of seats, one of the second transceivers is arranged.

Advantageously, the second transceiver are arranged in a head part of the aisle seat. At this point, the second transceivers have the greatest visibility because they are located directly on the usually obstacle-free head and ceiling space. The probability of successfully contacting one of the first transceivers is highest at this elevated point.

In an advantageous embodiment, a first transceiver is arranged on each of the head sides of the passenger cabin. Usually the pages are called head pages connected by a passage. They are at the same time the two furthest apart sides of the passenger cabin. By arranging the first transceivers at the greatest distance from each other, the largest possible area is supplied with data. This arrangement is therefore particularly favorable in terms of supply efficiency.

Advantageously, the coverage areas of the transceivers are aligned at the top of each side to the opposite side of the head. This ensures that the area between the header pages receives a particularly good network coverage and thus service quality. In particular, with sufficient coverage of the two service areas, it is possible for them to overlap, whereby redundancy of the data transmission paths is achieved.

Furthermore, at least one first transceiver can advantageously be arranged in the area of the ceiling, the supply area of which is aligned with the first transceiver arranged on the top sides. This is particularly favorable in the case where the coverage areas of the first transceivers arranged at the head ends are not sufficient to supply the entire passenger cabin with wireless data transmission. The additional first transceivers on the ceiling also make it possible to increase the signal quality and increase the redundancy of the data transmission by means of a further transmission path.

The first transceivers on the head sides and the first transceivers on the ceiling may be arranged in a line, with the coverage area of the first transceiver arranged on the ceiling being aligned with the respective next first transceiver. As a result, a chain of first transceivers is formed, which provide each other by their supply areas each other for the intervening second transceiver redundant data transmission. The arrangement in a line causes a particularly simple construction.

In a further embodiment, the first transceivers arranged on the head sides can be arranged on a first side of the passage. The ceiling mounted first transceivers may then be disposed on a second side of the passageway. This arrangement of the first transceivers causes the transmission path between the second transceivers arranged in the geared seats and the first transceivers respectively on the side on which the first transceivers are arranged, can not be interrupted by persons who are in the passage. This reduces the number of network breaks and improves service quality.

Particularly in the case of very long passenger cabins, it may be advantageous to arrange the first transceivers alternately from one head side to the other along the passage in each case on the first and the second side of the passage. Thus, it is ensured that in the area of the single first transceiver at least a part of the rows of seats is not affected by influences from the passage. If there are no disturbing influences from the passage, a redundancy of the data transmission paths is still ensured.

Advantageously, the coverage area of the first transceivers arranged on the top sides is located on the first transceivers closest to them and on the coverage area the first transceiver arranged on the ceiling is aligned with the first transceiver closest to it along the passage. This results in a particularly good network coverage.

Advantageously, the coverage areas of the first transceivers may be oriented so that a boundary of the coverage areas is substantially parallel to the side of the passageway at which the first transceivers are located. In this way, the first transceivers each cover the page on which they are arranged. Furthermore, by tilting the service area on the opposite side to a larger area of the opposite side is covered by the respective first transceiver. This in turn increases the redundancy and thus the quality of service.

Furthermore, it can be provided that the first transceivers are arranged in pairs opposite each other on both sides of the passage. This already ensures a redundant supply of the aisle seats on both sides of the passage. If the ranges of the first transceivers are large enough, a quadruple or even higher redundancy can be achieved on individual seats. This ensures even greater service quality.

The first transceivers can furthermore be arranged in the region of the side walls. This is particularly advantageous when data lines are difficult to install on or in the ceiling. An arrangement in the region of the side walls in this case allows a simplified construction of the transceiver arrangement.

The coverage areas of the first transceivers may advantageously be aligned with the opposite side wall. As a result, the area between the side walls, ie the space in the passenger cabin, is supplied with a wireless network.

In each row of seats, another second transceiver can be arranged in the seat arranged next to the aisle seat. This allows a network connection even if the second transceiver arranged in the aisle seat is covered by a human body part or an object, for example a jacket placed over it. In this case, the other second transceiver can take over the data transmission and supply the remaining seats of the row of seats with network access. If a particularly high quality of service is desired, a second transceiver can also be arranged in each seat.

Advantageously, the data transmission through the transceiver channels are provided with different frequency. Since the data transmission rate is shared on one and the same channel among all in the coverage area of the transceivers operated with this channel, the use of different channels can further increase the data transmission rate and reduce the interfering interference of the different transceivers.

In a particularly advantageous embodiment, transceivers whose coverage areas overlap use different channels. This avoids in particular that the wireless network components interfere with each other. It also reduces the number of erroneously transmitted data and thus the number of repeat requests, thereby increasing the usable data bandwidth and, in turn, improving service quality.

The transceiver arrangement explained above is particularly suitable for constructing a wireless system in a flying cab. Therefore, an aspect of the invention also relates to an arrangement of a wireless communication system in a means of transport, in particular in an aircraft and more particularly in a passenger cabin. Another aspect of the invention relates to an aircraft provided with such a communication system, in particular an aircraft.

• - hohe Signaldämpfung in der Luft
• - Multi-Weg-Effekte
• - Abschattung durch Personen und Gegenstände
• - „Quality of Service“ der Verbindung.

When constructing an arrangement of a communication system for an aircraft cabin or similar passenger cabins in means of transport, there is the problem that a very high data rate and wireless communication link can only be realized in certain frequency ranges due to the required bandwidth and the regulated frequency bands in a passenger cabin. At correspondingly high frequencies, however, the following effects play an essential role for operation in an aircraft passenger cabin:

• - high signal attenuation in the air
• - Multi-way effects
• - Shading by persons and objects
• - "Quality of Service" of the connection.

One aspect of the invention is directed to finding an optimum between these parameters for the meaningful operation of such a system.

For this purpose, in a particularly preferred embodiment of the transceiver arrangement and / or a communication system constructed therewith, the above enumerated parameters are considered together. A particularly preferred embodiment provides an arrangement of first Transceivers (so-called access points, access points) at the cabin ceiling and the second transceiver (especially so-called "seat points", seat points) in the passenger seats. In the embodiment of the transceiver arrangements according to the invention and / or the communication system thus constructed and / or the passenger cabin provided therewith, not every seat, but only every row of seats receives a transceiver. Within the row of seats, the individual seats are connected with cables. Other connections between the seats and the transceivers in the respective rows of seats are conceivable. It is particularly preferred that each seat transceiver can be reached by two ceiling transceivers. Such redundancy increases the "quality of service", in particular the communication stability. In alternative or additional embodiments, to further increase redundancy, each row of seats may be equipped with two rather than just one transceiver. Preferably, however, seat transceiver is in turn reachable by at least two overhead transceivers. In such a case one would have a quadruple redundancy for each seat.

Due to the selected installation points and emission characteristics of the transceiver, in addition to a high data rate, a high quality of service is additionally achieved for a WLAN system that can be set up with the arrangement according to the invention. Furthermore, not every passenger seat must be equipped with a transceiver, it is enough, for example, one transceiver per row of seats. This leads to a minimization of the number of required transceivers. If greater redundancy is considered beneficial, another transceiver can be installed per row of seats.

1 shows a passenger cabin 10 , an aircraft 11 namely an aircraft in particular. The passenger cabin 10 has headers 12a . 12b as well as side walls 14a . 14b on. Between the head pages 12a . 12b runs a passage 16 ,

Between the passage 16 and the side walls 14a . 14b rows of seats each extend 18 , which seats three passengers 20 Offer. The seats of the rows of seats 18 provide the passengers 20 Access to media such as radio and television programs, games or the Internet. These are in the rows of seats 18 for example, provided in the armrests connections for headphones and in the back or armrest screens. In addition, unillustrated input means such as buttons, touch screens, finger pads, etc. may be provided to input data. To transmit the data necessary for displaying these media to players integrated in the seats and, conversely, to transmit data from the passengers for controlling the media or for sending over the Internet, are at the head pages 12a . 12b first transceiver 22a arranged. The first transceivers 22a each have a substantially conical supply area 24a on.

To the network coverage in the passenger cabin 10 To improve further is on or in a ceiling 42 the passenger cabin 10 an additional first transceiver 22b who has a supply area 24b has arranged. By overlapping the coverage areas 24a . 24b arise double cover areas 26 by more than a first transceiver 22a . 22b are recorded.

On the rows of seats 18 is each at a directly on the passage 16 arranged aisle seat 28 a second transceiver 30 arranged. The arrangement of the second transceiver 30 in the hallway seats 28 it follows from that in this Position an arrangement of the largest number of second transceivers 30 in double coverage areas 26 is reached.

The data transfer from and to the rows of seats 18 takes place wirelessly between the first transceivers 22a . 22b and the second transceivers 30 , From the second transceivers 30 becomes the first transceiver 22a . 22b For example, transmit what media the passenger 20 selected for display. From the first transceivers 22a . 22b will then send the desired data to the second transceiver 30 transfer.

The seats of the rows of seats 18 are interconnected by a signal distribution network 32 connected with each other. The second transceiver 30 every row of seats 18 feeds into this signal distribution network 32 those of the first transceivers 22a . 22b received data. Furthermore, via the signal distribution network 32 For example, inputs from the passengers to the second transceiver 30 forwarded this data to the first transceiver 22a . 22b transmits wirelessly.

In this embodiment, the first transceivers 22a . 22b in the middle above the passage 16 arranged. In 2 are the first transceivers 22a . 22b on the sides of the head 12a . 12b are arranged, opposite the center of the passage 16 to a first page 34 offset. Furthermore, their coverage areas 24a towards a second page 36 aligned, so that a limit 38a the service areas 24a substantially parallel to the gangway ends of the rows of seats 18 on the first page 34 runs.

The first transceiver 22b is on the second page 36 on the ceiling 42 the passenger cabin 10 arranged. Also the supply area 24b of the first transceiver 22b is aligned so that a limit 38b of the supply area 24b substantially parallel to the gangway ends of the rows of seats 18 on the second page 36 runs.

The first transceivers 22a . 22b are each aligned so that their supply areas 24a . 24b cover the passage and the opposite side. By this arrangement, the double-coverage areas become 26 increased. Furthermore, multiple coverage areas form 40 out.

In the 3 shown transceiver arrangement makes it possible to achieve such multiple covers more frequently. On both sides of the passage 16 are at the top of the head 12a . 12b first transceiver 22a attached, each one the second transceiver 30 on their respective page. At the ceiling of the passenger cabin 10 are in addition again on both sides 34 . 36 of the passage 16 first transceiver 22b arranged, in turn, with their supply areas 24b mainly the gangway ends of the rows of seats 18 on your side 34 . 36 provide network access. This arrangement results locally on the aisle seats 28 limited double coverage areas 26 ,

4 shows an example of a radiation characteristic of the first transceiver 22b who is at the ceiling 42 the passenger cabin 10 is attached. The supply area 24b of the first transceiver 22b extends in this model over several rows of seats 18 , The model used here does not cover the area directly below itself. However, it is possible to have additional antennas in the first transceiver 22b also to cover this area.

The second transceiver 30 is in a headboard 44 of the aisle seat 28 arranged. From this position he has a clear view of the first transceiver 22b , The second transceiver 30 has a narrower coverage area 46 that when assembling the second transceiver 30 on the first transceiver 22b can be aligned.

Also the directional characteristic of the first transceiver 22a . 22b can, as in 5 shown to be adjusted. This is exemplary of a first transceiver 22b shown the first transceiver 22a However, they have similar possibilities. Is the first transceiver 22b in the middle of the passage 16 arranged, he must have a relatively wide coverage area 48a which has the passage seats 28 on both sides 34 . 36 of the passage 16 covers. Are the first transceivers 22b on the other hand, each arranged above the corridor seats, so the supply area 48b significantly narrower. Depending on the desired double or multiple coverage, there are also other asymmetric coverage areas, for example the coverage area 48c , conceivable.

To further increase the reliability can, as in 6 shown in each row of seats 18 another transceiver 30 be provided. Thus, additional redundancy is not limited to double or multiple coverage areas 26 . 40 but also by additional acceptance points within the coverage areas 24a . 24b guaranteed.

Is a mounting on the ceiling 42 the passenger cabin 10 or at the head ends 12a . 12b hard to realize, then it can be easier, as in 7 shown the first transceiver 22a . 22b in the side walls 14a . 14b to install. Also an installation over the rows of seats 18 is possible. An exemplary orientation of the service areas 24a . 24b in this case is in 8th shown.

Of course it is also possible, as in 9 shown to combine several of these approaches. In addition, it can also be favorable in poor conditions, in each seat a second transceiver 30 provided.

For wireless communication in passenger cabins 10 deployable radio systems usually have several different operating frequencies, called channels. For example, 13 channels are defined for the widespread WLAN standard 802.11b. Such a division into several channels is also carried out in all newly developed radio standards.

A first product for high data rate data transmission is a 60 GHz system from Si-Beam. As channel measurements have shown for different arrangements of this system, various effects play an essential role in the operation of an aircraft passenger cabin. For example, the high signal attenuation at high frequencies, the multi-path effects from reflections on objects and walls are responsible for a deterioration in the achievable quality of service of a wireless network realized therewith.

To reduce these disturbances are in adjacent service areas 24a . 24b different channels used for wireless data transmission. Especially in double and multiple coverage areas 26 . 40 This can significantly reduce interference.

Exemplary channel partitions for a system with four frequency channels are in the 10 and 11 shown. In 10 is a plurality of first transceivers 22b provided, each above the passage 16 on the ceiling 42 the passenger cabin 10 are attached. Depending on the direction in which the first transceiver 22b radiate different channels, indicated by the numbers 1, 2, 3 and 4.

11 shows a similar low-interference distribution of channels for first transceiver 22b , each in the area of the sides of the passage 16 on the ceiling 42 are arranged.

Taking into account the high signal attenuation in the air, the multi-way effects as well as the shading by persons and objects can be optimized arrangements of the first transceiver 22a . 22b as well as the second transceiver 30 be determined in the passenger seats. As a special feature of the transceiver does not receive every seat, but only every row of seats 18 a second transceiver 30 , Within the row of seats, the individual seats are connected to cables or other WLAN systems. Every second transceiver 30 is possibly of two first transceivers 22a . 22b reachable. This redundancy increases the quality of service. To further increase the redundancy, each row of seats 18 with two instead of just a second transceiver 30 be equipped. Again, if possible every second transceiver 30 again from two first transceivers 22a . 22b reachable. In this case, there would be a quadruple redundancy for each seat.

Through the selected installation points and radiation characteristics of the transceivers 22a . 22b In addition to a high data rate, a high service quality for the WLAN system is additionally achieved. Furthermore, not every passenger seat needs a second transceiver 30 be equipped, but only each row of seats 18 , This leads to a minimization of the number of required transceivers 30 , To further increase the quality of service can be another second transceiver 30 per row of seats 18 to be built in.

The seats in the rows of seats 18 can also be split up differently. For example, an asymmetrical arrangement with 2 seats on the first page 34 and three seats on the second page 36 conceivable. Likewise, with a large number of seats per row of seats 18 additional passes 16 be provided.
