Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims priority to European Patent Application No. 14172444.3, filed Jun. 13, 2014, the entire content of which is incorporated herein by reference in its entirety. 
       FIELD 
       [0002]    The present invention relates to a method for the installation of an outdoor unit (O.D.U), the installation being made with a single electronic device able to help the installer and to give appropriate information during different steps of the installation. The present invention also relates to the electronic device used during the installation. The invention also relates advantageously to reporting on the installation to a third party. 
         [0003]    By “O.D.U”, it should be understood all the elements that constitute what is commonly called a “satellite antenna”; these elements include a satellite dish (also called “antenna”), a Low Noise Converter—LNB, in some examples a transmitter- and various mechanical elements involved in pointing the satellite dish and the LNB. 
         [0004]    The O.D.U cooperates with an indoor unit (I.D.U), which is either a satellite TV receiver or a modem, placed inside a house. The receiver allows the reception of television signals and displays them on a screen. Most of the time, the O.D.U and the I.D.U. are linked by a physical wire. This physical wire allows the transmission of signals emitted by a satellite and received by the O.D.U from the O.D.U to the I.D.U., and in some systems, this physical wire allows also the transmission of signals from the I.D.U. to the O.D.U and to the satellite. 
       BACKGROUND 
       [0005]    Proper installation of a satellite dish remains a difficult operation for users. They often prefer to hire a professional installer. If a user wants to install his own O.D.U, the user often has to climb a ladder to fix the O.D.U in a suitable location of his/her dwelling. Smartphone Apps or Tools are available to help to choose a correct installation position and even roughly direct the dish to receive the satellite signals. For example, the smartphone indicates the elevation angle and azimuth direction to apply to the dish. Once the dish has been directed according to the smartphone&#39;s indications, the user has then to enter his home to check whether the signals are correctly received and transmitted to the I.D.U. 
         [0006]    In most cases, the user has to make a number of return journeys to refine the positioning of the dish until the dish is in the correct position and supplies good signal quality. These operations make the installation of the O.D.U long and laborious. The use of acoustic signals which are provided in some cases at the O.D.U are so far not sufficiently accurate and sometimes not able to identify the correct satellite. This often results in the user returning between the O.D.U and the I.D.U. Satellite level meters inserted in the physical cable between the IDU and the ODU have the same disadvantages as the acoustic signal described above. 
         [0007]    In addition, different operators clearly prefer the installation of O.D.U being performed by professional installer, so that the installation can be validated. If a malfunction occurs after proper installation of the antenna (such a malfunction can occur for different reasons, for example a fast growing vegetation which obscures the satellite signal from and the dish). If that installation has not been done by a professional installer, a remote technical assistance will lack information to help the user solve the problems on his own O.D.U. 
       SUMMARY 
       [0008]    As aspect of the invention aims to remedy all or some of the disadvantages of the above identified background. An embodiment of the invention essentially makes the installation of O.D.U easy for all users, no returns between the O.D.U and the I.D.U. being necessary.

       DETAILED DESCRIPTION 
       [0046]    The figures and the following description illustrate specific exemplary embodiments of the invention. It will thus be appreciated that those skilled in the art will be able to devise various arrangements that, although not explicitly described or shown herein, embody the principles of the invention and are included within the scope of the invention. Furthermore, any examples described herein are intended to aid in understanding the principles of the invention, and are to be construed as being without limitation to such specifically recited examples and conditions. As a result, the invention is not limited to the specific embodiments or examples described below, but by the claims and their equivalents. 
         [0047]    Referring to  FIG. 1 , it is depicted a schematic representation of different elements involved in the method according to the invention, and the exchanges between these elements. 
         [0048]    On this picture, an O.D.U  101  has to be installed on a house  102 , typically on the wall of the house  102 . The O.D.U  101  is linked to an I.D.U.  103  located inside the house and connected to a TV set  120  or a Personal Computer. The link between the O.D.U  101  and the I.D.U.  103  is a wire  104  that allows an exchange of information between these two units. In the case of a “Tooway” system, the exchange of information is bidirectional. 
         [0049]    A user  105  wants to install the antenna on his dwelling. The user is equipped with an electronic device  106  which can be for example a smartphone, or a tablet, or any other electronic device comprising a screen and small enough to be easily brought up a ladder for example. Thus, in the embodiment, the electronic device  106  is a handlet that is easily transportable. A specific application APP is memorized in the electronic device  106  in order to achieve the described example of the invention. The electronic device  106  includes several physical or hardware components. For example, the electronic device  106  includes a physical processor, a screen and a memory (broadly termed “machine readable medium”). The memory includes specific machine executable instructions for carrying out the application APP, and in particular for carrying out one or more steps of the method according to the invention and also various feature(s) of the application APP. The physical processor is arranged to be in communication with the memory to execute the machine executable instructions. As a non-limiting example, the physical processor is configured to execute specific machine executable instructions for carrying out various checks (as described hereinafter), for determining the pointing information (including the various comparison and mathematical operations to determine the pointing information), for displaying or causing to display the various information (as described hereinafter, e.g. data, messages, graphs, . . . ), for transmitting or causing to transmit various data (as described hereinafter, e.g. data, commands, . . . ) and for processing various data (collected for example by its receiver/antenna and the GPS module). 
         [0050]    On the described example, the application proceeds with preliminary check operations: a first check consists in making sure that a wireless (wi-fi, blue tooth, or other . . . ) connection exists between the electronic device  106  and the I.D.U.  103 , especially with the modem or receiver of the I.D.U.  103 . If no connection is detected, an appropriate message  201  ( FIG. 2 ) is displayed on the screen of the electronic device  106 . A second check consists in making sure that a GPS module  107  of the electronic device  106  is working and can receive useful GPS information. If the GPS module  107  of the electronic device  106  is not working, an error message  301  (FIG.  3 ) is displayed on the screen of the electronic device  106 . In accordance with an embodiment of the invention, the first and second checks can be conducted by the processor of the electronic device  106  in accordance with specific machine executable instructions. 
         [0051]    Once the preliminary checks achieved, the user  105  gets through the GPS module  107  of the electronic device  106  a pointing information. The pointing information is determined by the electronic device  106  based on geographical position information obtained by the GPS module  107 . In an embodiment of the invention, machine executable instructions are executed by the processor of the electronic device  106  to determine the pointing information. The pointing information is displayed on the screen of the electronic device  106  ( FIG. 4 ). The pointing information determined by the processor gives a value for an elevation  401  and a value for an azimuth  402  to apply to the antenna of the O.D.U  101 . To help the user  105  to correctly orientate the antenna, a graphical indication  403  is displayed on the screen of the electronic device  106 , the graphical indication  403  showing the antenna to be installed in the correct position. In some embodiments, as shown on  FIG. 4 , two different kinds of antenna are represented, the user having the possibility to determine which represented antenna corresponds to the antenna he has to install. Simultaneously, an information  404  dealing with the appropriate spot to use for a certain transmitting VSAT system is also displayed on the screen of the electronic device  106 . 
         [0052]    In some embodiments, thanks to the specific application of the electronic device  106 , the electronic device will configure the I.D.U.  103  in a correct installation mode. The following steps will occur:
       ascertaining on which spot the electronic device  106  should program the I.D.U.  103 ; this information  404  is given by the electronic device  106 ;   sending a command from the electronic device  106  to the I.D.U.  103  in order to activate an installation mode on the I.D.U.  103 ,   sending a command from the electronic device  106  to the I.D.U.  103  in order to indicate to the modem or receiver which spot or coverage to choose, the spot defining the polarization and the frequency to look for during the installation of the O.D.U  101 .       
 
         [0056]    When the user  105  starts to move the antenna, the user then instantaneously receives on the electronic device  106  a signal quality information SQI. On  FIG. 5 , this signal quality information is a signal quality giving a current SNR value  501  which is displayed on the screen of the electronic device  106 . In other embodiments, the signal quality information SQI is not a signal to noise ratio, but a value which can correspond for example to CBER, VBER, MER, C/N, Power, dBm and dBu. The reception signal quality information SQI is transmitted by the I.D.U.  103  to the electronic device  106  by a wireless link  108 ; beneficially, the wireless link is established between the electronic device  106  and a wireless device  109  plugged onto the I.D.U.  103 . The user  105  moves the antenna accordingly, pointing the O.D.U  101  according to the received signal quality information SQL 
         [0057]    Beneficially, the electronic device  106  stores an optimum value  502  of the signal quality during the O.D.U  101  pointing. Thus, if the user  105  keeps on moving the antenna after having reached the optimum value  502 , the user knows that he/sher can get again this optimum  502  value by moving back the antenna. 
         [0058]    Beneficially, the reception signal quality information SQI is restored by the electronic device  106  as a sound signal whose frequency, pulse and/or intensity varies with the reception signal quality information. 
         [0059]    In an embodiment, when the user thinks that he/she has completed the installation of the O.D.U  101 , the user proceeds, through the electronic device  106 , to a validation step. To this end, some data is sent from the electronic device  106  using the specific application to a remote data center  110 . 
         [0060]    More specifically, the following data can be transmitted from the electronic device to the remote data center:
       the current value of the signal quality once the O.D.U  101  is no longer moved by the user  105 ;       
 
         [0062]    some pictures PIC of the installation taken by a camera  111  of the electronic device  106 ; these pictures will notably allow the remote data center  110  to determine the reasons of a possible future failure;
       the GPS location of the installation location.       
 
         [0064]    The specific application APP can use a message, for example an e-mail to send through a cellular network this data to a remote data center  110 . The data, and especially the current value of the signal quality will be compared to a predetermined threshold value, the O.D.U  101  installation being validated only if the threshold value is reached. In another embodiment, this comparison is computed in the electronic device  106  itself. 
         [0065]    In some embodiments, the I.D.U.  103  use is disabled until the O.D.U  101  installation is validated. The message is secured and has a unique semantic integrity which is associated with the particular installation. 
         [0066]    A message  601  of unsuccessful installation ( FIG. 6-A ), or if necessary a failure message  602  ( FIG. 6-B ) is then sent from the remote data center  110  to the electronic device  106 . 
         [0067]    It will be appreciated by one skilled in the art that the disclosed arrangements and methods described herein represent a solution to the technological problem currently faced by installers of a satellite dish.

         [0069]    Execution of the sequences of machine instructions contained in a memory causes the processor or processing unit to perform at least some of the process steps or function(s) of the procedures described herein. One or more physical processors or physical processing units in a multi-processing arrangement may also be employed to execute the sequences of instructions contained in the memory or machine/computer readable medium. In alternative embodiments, hard-wired circuitry may be used in place of or in combination with software instructions. 
         [0070]    The term “computer readable medium” or “machine readable medium” or “machine storage medium” or “memory” as used herein refers to any medium that participates in providing instructions to a processor or processing unit for execution.
