FIELD

Various embodiments of the disclosure relate to signal retransmission and amplification for mobile and static receivers. More specifically, various embodiments of the disclosure relate to an electronic apparatus and method for retransmission of signals using aerial vehicles.

BACKGROUND

Advancements in the field of wireless communication have led to development of various technologies that allow transmission or reception of data through over-the-air (OTA) signals. For example, devices can receive data through Wi-Fi signals, Bluetooth® signals, radio signals, signals from terrestrial broadcast stations, signals from telecom base stations, satellite signals, and the like. Unlike wired communication, wireless communication requires the device to be present within a coverage area of a remote transmitter. In some cases, signals reception can be bad if the devices are in a difficult terrain or in a very remote location where there are very few transmitters. Additionally, certain signals, especially ones transmitted by a terrestrial transmitter, suffer from terrestrial interference or loss due to various obstacles, such as trees, hillsides, buildings, mountain ridges, and the like. Based on the wavelength and the size of obstacles, some signals suffer from diffraction. Lower frequencies may diffract around large obstacles, such as hills. Similarly, signals for cellular communication may be dominated by ground-plane effects as they travel over the rooftops of the urban environment. Such signals can then diffract over roof edges into the street, where they may suffer from multipath propagation, absorption, and other effects.

SUMMARY

An electronic apparatus and method for retransmission of signals using aerial vehicles is provided substantially as shown in, and/or described in connection with, at least one of the figures, as set forth more completely in the claims.

DETAILED DESCRIPTION

The following described implementation may be found in the disclosed electronic apparatus and method of retransmission of signals using aerial vehicles. Exemplary aspects of the disclosure provide an electronic apparatus, which may provide a method of retransmission of signals using unmanned aerial vehicles. The electronic apparatus (which may be mounted on, for example, an unmanned aerial vehicle (UAV) such as a drone or a balloon tethered in air (below stratosphere)) may be configured to retransmit signals (such as a radio frequency (RF) signal or an optical signal) from one or more remote transmitters to one or more receivers disposed inside an electronic device, for example, a smartphone, a wearable device, a vehicle, an internet of things (IOT) device, and the like.

At any time-instant, the electronic apparatus may receive a first signal (for example, a cellular signal that carries cellular communication data, a satellite signal that carries geolocation data or media content, a radio frequency signal that carries the media content broadcasted by a terrestrial broadcast station, a Wi-Fi signal, or a Bluetooth® signal) from a remote transmitter based on a location that is within a signal coverage area associated with the remote transmitter. By way of example, and not limitation, the remote transmitter may be one of a base station of a cellular network, a satellite's transponder, a terrestrial broadcast station, a Wi-Fi router, a Wi-Fi repeater, a repeater for a cellular network, a Bluetooth® transmitter, or an optical transmitter that uses an optical signal for a point-to-point communication. Thereafter, the electronic apparatus may be configured to process the received first signal to obtain a second signal and may transmit, using one or more antennas, a beam of the second signal to the electronic device. The second signal may correspond to a wireless communication standard that may be same as or different from a wireless communication standard associated with the first signal. For example, both the first signal and the second may correspond to ATSC standard. With the retransmission of the first signal, the disclosed electronic apparatus may be able to provide satisfactory reception of signals (from remote transmitters), while avoid common issues related to terrestrial and/or atmospheric conditions that impact reception of signals over larger distances or over difficult terrains, such as hillsides, trees, buildings, or mountain ridges. In comparison to conventional solutions, the disclosure provides a way to provide cost effective and reliable wireless communication or reception between remote transmitter(s) and static/moving receivers on the ground.

In an embodiment, the charging circuitry122may be configured to receive a directed beam of optical energy from an optical power transmitter that may be included in the battery charger. In another embodiment, the charging circuitry122may be configured to receive electric power directly via cables from the battery charger coupled to a charging station.

In operation, the electronic apparatus102may receive a trigger input, for example, to turn-on the electronic apparatus102or to activate a mode. Based on the input, the electronic apparatus102may control a movement of the first UAV104. In case the first UAV104is a balloon, the trigger input may inflate and/or release the balloon to a location (i.e., a static aerial location) within a signal coverage area of the remote transmitter106(below stratosphere). The trigger input may be directly received via an interface integrated into the electronic apparatus102and/or via the electronic device108. For example, the electronic apparatus102may be configured to receive the trigger input, via an I/O device (shown inFIG.2) or a network interface (also shown inFIG.2) of the electronic apparatus102.

In accordance with an embodiment, the electronic apparatus102may be configured to control a movement of the first UAV104to a location within the signal coverage area of the remote transmitter106. The remote transmitter106may be, for example, a base station of a cellular network, a satellite's transponder, a terrestrial broadcast station, a TV transmitter (e.g., an ATSC or (Digital Video Broadcast) DVB transmitter), a Wi-Fi router, a Wi-Fi repeater, a repeater for a cellular network, a Bluetooth® transmitter, an optical transmitter that uses an optical signal for a point-to-point communication, and the like.

At the location, the electronic apparatus102may be configured to scan and detect a first signal from the remote transmitter106. The remote transmitter106may or may not always be present in a direct LOS of the electronic device108(i.e., that includes receiver(s)). The location of the electronic apparatus102may be maintained such that the electronic device108on the ground is in a line-of-sight (LOS) of the electronic apparatus102(mounted on the first UAV104). The control of the movement of the first UAV104is described, for example, inFIGS.3A,3B, and3C.

The first signal may be an RF signal, or an optical signal transmitted by the remote transmitter106. By way of example, and not limitation, the first signal may include a cellular signal that carries cellular communication data, a satellite signal that carries geolocation data, media content, or internet data, a radio frequency signal (e.g., a Digital Television (DTV) or Advanced Television Systems Committee (ATSC) signal) that carries the media content broadcasted by a terrestrial broadcast station, a Wi-Fi signal, or a Bluetooth® signal. The receiver circuitry114of the electronic apparatus102may receive the first signal from the remote transmitter106, based on the location. The first signal may correspond to a first wireless communication standard and may be associated with a type of service provider, such as a satellite data provider, a cable TV service provider, a cellular service provider, an internet service provider, or any short/long-range, point-to-point, or point-to-multipoint communication service provider. The reception of the first signal is described, for example, inFIG.3C.

After the reception, the signal processor116may be configured to process the first signal to obtain a second signal. The second signal may correspond to a second wireless communication standard, which may be same as or different from the first wireless communication standard associated with the first signal. By way of example, and not limitation, the second signal may be a cellular signal that carries cellular communication data, a radio frequency signal that carries the media content broadcasted by a terrestrial or satellite broadcast station, a Wi-Fi signal, or a Bluetooth® signal. While content of both the first signal and the second signal may remain same, the second signal may be processed for noise removal, amplification, and/or conversion to a form that may be suitable for a communication standard different from the one associated with the first signal. For example, if the first signal is a first ATSC signal that is received from the remote transmitter106(e.g., a terrestrial broadcast station), then the second signal may be a second ATSC signal or a Wi-Fi signal that carries the content of the ATSC signal received from the remote transmitter106. As another example, if the first signal is a cellular signal (e.g., as per 4thGeneration LTE standard), then the second signal may be a Wi-Fi signal that carries the content of the cellular signal. The signal processing is described, for example, inFIG.3C.

The transmission circuitry118of the electronic apparatus102may control the one or more antennas120disposed on the first UAV104to transmit a beam of the second signal to the electronic device108that includes one or more receivers. In accordance with an embodiment, the first wireless communication standard may correspond to a first frequency band and the second wireless communication standard may correspond to a second frequency band that may be different from the first frequency band. In such a case, the second signal may be transmitted in the second frequency band that may be different from the first frequency band in which the first signal is received from the remote transmitter106. The control of the one or more antennas120is described, for example, inFIG.3C.

In an exemplary scenario, the electronic device108used by the user124may face a weak signal coverage as the user124may be present in an environment that is either remote or includes a difficult terrain, such as hills, mountain ridges, or other terrestrial obstacles. In such a scenario, a user input may be provided to, for example, turn-on the electronic apparatus102or to activate a mode. Based on the user input, the electronic apparatus102may control the movement (i.e., a flight) of the first UAV104to a location within the signal coverage area of the remote transmitter106. At the location, the electronic apparatus102(while disposed on the first UAV104) may receive the first signal (e.g., a weak signal with a low SNR) from the remote transmitter106and may transmit the second signal (after processing the first signal to obtain the second signal) to the electronic device108that includes one or more receivers. The electronic apparatus102may transmit a directed beam of the second signal to one or more receivers included in the electronic device108. Thus, the first UAV104and the electronic apparatus102may together operate to provide an effective and optimal signal reception for the electronic device108(for example, a mobile phone, a tablet, and the like) on the ground.

The location of the first UAV104may allow the electronic apparatus102to receive the first signal from the first remote transmitter304, without much interference or loss from obstructions (such as hills, trees, or buildings).

FIG.3Cis a diagram that illustrates an exemplary scenario for retransmission of signals using aerial vehicles, in accordance with an embodiment of the disclosure.FIG.3Cis described in conjunction with elements fromFIGS.1,2,3A and3B. With reference toFIG.3C, there is shown an exemplary scenario300C. The exemplary scenario300C includes the vehicle302in the moving state on a hilly terrain. There is further shown the first remote transmitter304and the second remote transmitter306, each of which may be configured to have a functionality that is similar to the remote transmitter106, as illustrated and described inFIG.1. There is further shown a dash curve that indicates a boundary of the signal coverage area associated with the first remote transmitter304.

At any time-instant, the vehicle302may exit a geographical region that falls within the signal coverage area of the first remote transmitter304. The vehicle302may enter a geographical region that may fall within a signal coverage area of the second remote transmitter306, as shown inFIG.3C. However, there may be obstructions that may affect a stable, reliable, and direct communication (or just reception) between the electronic device108(mounted on the vehicle302) and the second remote transmitter306. The controller112may be configured to control a movement of the first UAV104to a location within the signal coverage area associated with the second remote transmitter306.

The receiver circuitry114may be configured to receive a first signal from the second remote transmitter306based on the location. The first signal may correspond a first wireless communication standard and may be received as one of an RF signal or an optical signal (i.e., as per free-space laser communication). By way of example, and not limitation, the first signal may include a cellular signal that carries cellular communication data, a satellite signal that carries geolocation data or media content, a radio frequency signal that carries the media content broadcasted by a terrestrial broadcast station, a Wi-Fi signal, or a Bluetooth® signal. In accordance with an embodiment, the first signal may be an ATSC signal or a DVB signal.

Upon the reception of the first signal from the second remote transmitter306, the signal processor116may be configured to process the received first signal to obtain a second signal. By way of example, and not limitation, the signal processor116may be configured to filter the first signal to remove noise and amplify the filtered signal. In case the received first signal is an optical signal, the signal processor116may receive an electrical signal based on conversion of the optical signal. As the first signal may be weak, the signal processor116may be required to increase the power of the received first signal while ensuring that the power gain improves the signal to noise ratio (SNR) of the received first signal.

In accordance with an embodiment, the signal processor116and/or other RF components may be configured to convert the first signal to the second signal such that the second signal corresponds to a wireless communication standard same as or different from the wireless communication standard associated with the first signal. By way of example, and not limitation, the second signal may include a cellular signal that carries cellular communication data, a satellite signal that carries geolocation data or media content, a radio frequency signal that carries the media content broadcasted by a terrestrial broadcast station, a Wi-Fi signal, or a Bluetooth® signal. In accordance with an embodiment, the second signal may be same as the first signals, i.e., an ATSC signal or a DVB signal. In such a case, the electronic apparatus102may operate as an ATSC-to-ATSC re-transmitter.

In some scenarios, the second signal may correspond to a wireless communication standard that may be different from the wireless communication standard associated with the first signal. As an example, the first signal may correspond to a cellular signal that carries cellular communication data and the second signal may correspond to a Wi-Fi signal that carries the same cellular communication data. As another example, the first signal may correspond to a cellular signal (i.e., first signal) that carries cellular communication data and the second signal may correspond to an RF signal other than the cellular signal. The RF signal may be same as the one used by a terrestrial broadcast station for DTV signals (such as ATSC signals). As another example, the first signal may correspond to an RF signal that carries media content (e.g., content over ATSC signals) broadcasted by a terrestrial broadcast station and the second signal may correspond to a Wi-Fi signal that carries the same media content. As another example, the first signal may correspond to a satellite signal that carries geolocation or internet data, and the second signal may correspond to a Wi-Fi signal that carries the same geolocation or the internet data. As another example, the first signal may correspond to a satellite signal that carries geolocation data and the second signal may correspond to an RF signal (other than a cellular signal). The RF signal may be same as the one used by a terrestrial broadcast station for DTV signals (such as ATSC signals).

In some scenarios, the second signal may correspond to a wireless communication standard that may be same as the wireless communication standard associated with the first signal. As an example, both the first and second signals may correspond to RF signals that carry the media content broadcasted by a terrestrial broadcast station (e.g., for ATSC 1.0/3.0 transmission). In such a case, the electronic apparatus102may operate as a broadcast repeater or a signal re-transmitter disposed on the first UAV104.

After the signal processing, the transmission circuitry118may be configured to control the one or more antennas120disposed on the first UAV104to transmit a beam of the second signal to the electronic device108that includes one or more receivers. In accordance with an embodiment, the one or more antennas120may be a directional antenna that may be configured to receive the first signal from the second remote transmitter306and may transmit a directed beam of the second signal to one or more receivers of the electronic device108disposed on the vehicle302. The directed beam may be transmitted to minimize a dispersal of the signal in free space.

In an embodiment, the electronic apparatus102may receive the first signal (such as a cellular signal or a satellite signal) from the remote transmitter106and may transmit signals (received from the one or more receivers on the ground) back to a remote receiver (that may be placed with or separate from the remote transmitter106).

In accordance with an embodiment, the second signal may be transmitted in a second frequency band that may be different from a first frequency band in which the first signal is received. In such a case, the first wireless communication standard may correspond to the first frequency band and the second wireless communication standard may correspond to the second frequency band. As an example, if the first signal in the first frequency band is one of a satellite signal, a DTV signal, a Wi-Fi signal, a Bluetooth® signal, or an optical signal (over free space), then the second signal in the second frequency band may be an RF signal that uses whitespace signal frequencies (e.g., 50 MHz and 700 MHz).

In accordance with an embodiment, the controller112may be configured to receive speed information associated with the vehicle302from a data communication system associated with the vehicle302. The data communication system may include suitable logic, circuitry, interfaces, and/or code that may enable the vehicle302to communicate with the electronic apparatus102(and the first UAV104), via the wireless communication network110. The data communication system may implement known technologies to support wired and/or wireless communication. The data communication system may include, but is not limited to, an antenna, a frequency modulation (FM) transceiver, a radio frequency (RF) transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a coder-decoder (CODEC) chipset, a subscriber identity module (SIM) card, and/or a local buffer.

Therefore, further description of the data communication system is omitted from the disclosure for the sake of brevity.

The vehicle302may include an in-vehicle network (not shown) to facilitate communication between internal components of the vehicle302. A person of ordinary skilled in the art will understand that the vehicle302may also include other suitable components or systems, in addition to the components or systems illustrated herein to describe and explain the function and operation of the present disclosure.

Such sensors which may be configured to acquire the speed information.

Based on the speed information, the controller112may be configured to determine an expected position of the first UAV104with respect to that of the vehicle302at a time-instant. The expected position of the first UAV104may correspond to an optimal position that allows the first UAV104to have the vehicle302in a direct LOS and to directly transmit to the electronic device108mounted on the vehicle302. Thereafter, the controller112may be further configured to determine a current position of the first UAV104. The current position of the first UAV104may include a ground position, a docked position, or any other position within the signal coverage area at the time instant. It may be determined whether there is a difference between the current position of the first UAV104and the expected position of the first UAV104at the time instant. In case the difference is above a threshold, the controller112may be configured to control the movement of the first UAV104until the difference between the current position of the first UAV104and the expected position is a minimum. This may enable the first UAV104to continuously track the movement of the vehicle302.

In accordance with an embodiment, the controller112may be configured to determine an expected relative speed of the first UAV104with respect to the vehicle302at a time-instant. The expected relative speed of the first UAV104may correspond to an optimum speed of the first UAV104with respect to a current speed of the vehicle302. The expected relative speed of the first UAV104may be determined such that the first UAV104may remain within a signal coverage area of the first remote transmitter304while having the vehicle302(or the electronic device108) in a direct LOS for signal transmission/reception. Thereafter, the controller112may be configured to determine a current relative speed of the first UAV104. It may be determined whether there is a difference between the current relative speed of the first UAV104and the expected relative speed of the first UAV104at a time instant. In case the difference is above or below a threshold, the controller112may be configured to control the movement of the first UAV104until the difference between the current relative speed of the first UAV104and the expected relative speed is a minimum. This may enable the first UAV104to continuously track the movement (and follow a path) of the vehicle302.

In an embodiment, the controller112may be configured to determine an expected speed with which the vehicle302is required to move with respect to that of the first UAV104. The expected speed of the vehicle302may correspond to an optimum speed that the vehicle302must have to remain in a direct LOS of the first UAV104. Thereafter, the controller112may be further configured to determine a current speed of the vehicle302. It may be further determined whether there is a difference between the current speed of the vehicle302and the expected speed of the vehicle302at the time instant. In case the difference is above or below a threshold, the transmission circuitry118may be configured to transmit a message that may include a call to change a speed of the vehicle302to match the expected speed. By way of example, and not limitation, the message may include a text, a sound, or a graphic item that may prompt the user124to change the speed of the vehicle302. The message may be displayed on a display device (for example, the display device212) associated with the electronic device108or the vehicle302.
