FIELD OF INVENTION
[0002] The embodiments of the present disclosure generally relate to systems and methods for fixed wireless access points. More particularly, the present disclosure relates to a system and a method for time-based power sharing for reverse powered Power over Ethernet (PoE) inputs.

BACKGROUND OF THE INVENTION
[0003] The following description of the related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section is used only to enhance the understanding of the reader with respect to the present disclosure, and not as admission of the prior art.
[0004] With the advancement in technology and data requirements, advanced telecommunication equipment(s) are placed in an open terrestrial environment for better connectivity to core network/access points. These telecommunication instruments placed in an open environment require a power supply equipment to operate. Normally, plug points/sockets are unavailable in the open environment. The equipment placed in the open environment may provide connectivity to the customers. Conventional current sharing systems for powering telecommunication instruments require all the connected input ports of a Power over Ethernet (PoE) system to be at equal voltage level for simultaneous current sharing among connected users. As a result, all the ports with active inputs will be under operation and have higher power dissipation leading to higher thermal temperatures. Further, losses are higher with the current sharing system leading to an increase in thermal case temperatures of Integrated Chips (ICs) used in the PoE system. This may further lead to reduced life-time and reliability of the conventional current sharing systems.
[0005] Further, conventional systems bring all the connected input ports to an equal voltage for simultaneously sharing current among the connected users. This may be inefficient and add to a Bills of Material (BoM) cost. Conventional systems lead to higher losses as conversion of input voltage to a fixed output voltage requires use of switching regulators at all input ports, leading to an increase in cost of the overall current sharing system.
[0006] There is, therefore, a need in the art to provide a system and a method that can mitigate the problems associated with the prior arts.

OBJECTS OF THE INVENTION

[0009] It is an object of the present disclosure to provide a system where power is taken from the connected ports and switched between the connected ports using a time-based approach to provide a fair share of power resource among the connected users.

[0015] In an embodiment, in response to a determination that the I2C request is not received, the processor may re-determine the one or more connected ports based on the detection of the minimum voltage across the one or more connected ports.
[0016] In an embodiment, the processor may utilize a capacitor bank for smooth transitioning to a next active priority port among the one or more priority ports and power the remote device during the transition.

[0037] The present disclosure uses a RMDU (Reverse Multi-Dwelling Unit) for routing data packets from a telecommunication instrument to particular ports connected in a customer premises and provide the required power for the telecommunication instruments. A reverse powering mechanism in the RMDU, takes power in from the connected ports to power-up the telecommunication instruments via a Power-over-Ethernet (PoE) system. Time-based power sharing architecture has been implemented which provides time-based power sharing mechanism of power resource distribution among the connected ports.
[0038] The various embodiments throughout the disclosure will be explained in more detail with reference to FIGs. 1-4.
[0039] FIG. 1 illustrates a block diagram representation (100) of a proposed system (124), in accordance with an embodiment of the present disclosure.
[0040] In an embodiment, to connect users in a fixed broadband wireless access solution, an intermediary unit such as a Reverse Multi-Dwelling Unit (RMDU) is used. The RMDU routes data packets from an outdoor telecommunication unit to connected ports connected at the customer premises and provides the power required for the outdoor telecommunication unit to operate.
[0041] As illustrated in FIG. 1, in an embodiment, power is taken from the connected input ports/connected ports (102-A, 102-B…102-N) and switched between the input ports (102-A, 102-B…102-N) using a time-based approach to provide a fair share of power resource among the connected users. The block diagram as shown in FIG. 1 further represents a hardware implementation of time-based power sharing mechanism for power distribution.
[0042] In an example embodiment, as shown in FIG. 1, power may be taken through a standard RJ45 Ethernet cable using Power-over-Ethernet (PoE) technology. A direct current (DC) power is separated from one or more data lines using one or more center-taps of Ethernet magnetics. One or more diode bridges (104-A, 104-B…104-N) may be used to accommodate any modes of PoE power-pair input. The one or more diode bridges (104-A, 104-B…104-N) may be configured to work with any polarity of power input received from the one or more connected ports. A person skilled in the art may appreciate that RMDU may be referred as PoE switch system (124) or a system (124) throughout the disclosure. One or more voltage dividers (106-A, 106-B…106-N) is used with the system (124) for supplying equal voltages across one or more switches (108-A, 108-B…108-N).
[0043] In an embodiment, the system (124) may distinguish a connected port by detecting the voltage at that port. For a fair share of the power between the connected inputs, an auto time sharing logic may be implemented which may be controlled by a micro-controller/processor (202) using the one or more switches (108-A, 108-B…108-N) configured with each of the input ports (102-A, 102-B, 102-N). With the continuous monitoring of connected ports, power may be drawn from all the connected ports using a round-robin approach. At any instant the power may be drawn from any one port, and for the next time instant, power may be drawn from the next connected port.
[0044] In an embodiment, the system (124) may include one or more bulk capacitors/capacitor bank (110) for smooth transition of power during switch-over from one port to the other. A bleeder circuit (112) may be implemented with the one or more bulk capacitors (110) to dissipate the charge stored in the bulk capacitors during any power outage. An output generated through the switching of the connected ports may be fed to a switching converter (114) for a stabilized 54V±1% output. The switching converter (114) may include a Buck Boost DC to DC convertor. The output may be further provided to a Power sourcing Equipment (PSE) output port (116) for the outdoor telecommunication equipment to operate using the PoE technology via a PSE switch (118).
[0045] In an embodiment, the system (124) may determine one or more connected ports among the one or more ports (102-A, 102-B, 102-N) based on detection of a minimum voltage across the one or more connected ports. At least one switch among the one or more switches (108-A, 108-B, 108-N) may be configured with each of the one or more ports (102-A, 102-B, 102-N) to sequentially activate one or more priority ports among the priority list of ports and power a remote device.
[0046] In an embodiment, one or more diode bridges may be configured with each of the one or more ports (102-A, 102-B, 102-N) to receive a power input via the standard RJ45 Ethernet cable using a Power-over-Ethernet (PoE) technology. The system (124) may distribute the power input to the remote device based on the sequential activation of the one or more priority ports. The one or more ports (102-A, 102-B, 102-N) may be connected using Ethernet cables of different lengths connected to the customer premises. Usually upon combining the power inputs from the one or more ports (102-A, 102-B, 102-N) may lead to a maximum power drawn from a connected port which has the highest potential difference among the other ports, i.e. maximum power will be drawn from the port with the least cable length. Consequently, the customer with the least cable length may be encumbered to pay for the entire broadband system operation. Hence, the system (124) may use a time-based power sharing solution which may provide a fair-share of power resources among the connected customer’s input ports.
[0047] In an embodiment, the system (124) may determine a priority list of ports among the one or more connected ports by detecting a predetermined voltage across the one or more connected ports.
[0048] In an embodiment, the system (124) may determine if a predetermined voltage is detected across the priority list of ports. In response to a positive determination, the system (124) may enable a Power Service Equipment (PSE) port among the priority list of ports and power the remote device through the PSE port for the predetermined period. In response to a negative determination, the processor (202) is to simultaneously power the remote device through the one or more connected ports. The system (124) may sequentially activate one or more priority ports among the priority list of ports.
[0049] In an embodiment, the system (124) may determine if an Inter-Integrated Circuit (I2C) request is received from a central processing unit (CPU) upon completion of the activation of the one or more priority ports and in response to a second positive determination process the I2C request. The system (124) may, in response to a second negative determination, re-determine the one or more connected ports based on the detection of the minimum voltage across the one or more connected ports.
[0050] In an embodiment, the system (124) may utilize the capacitor bank (110) for transitioning to a next active port among the one or more of ports and power the remote device during the transition.
[0051] In an embodiment, the system (124) may provide protection against under-voltage lockout, hot-plugging, surge protection, and an output short-circuit protection due to transients, surges, etc.
[0052] For example, in an embodiment, a time based power sharing mechanism used by the system (124) includes switching of active ports at every 30 seconds to provide a fair share of the power resources among the connected inputs over a larger time frame. During boot-up, all the switches at the / ports are kept ON by default by a resistor pull-down configuration for an active-low switch, and the PSE port switch (118) is kept OFF. After 15 seconds of system boot-up, the time based power sharing may be implemented. Further, once the power sharing logic kicks in, the switch at the PSE port (116) is turned ON after 5 seconds. A micro-controller on the power board may also communicate with the base-band or CPU for regular hand-shaking to detect the status of the micro-controller/processor (202) operation and may also be used for any software upgradation over-the-air.
[0053] Although FIG. 1 shows exemplary components of the network architecture (100), in other embodiments, the network architecture (100) may include fewer components, different components, differently arranged components, or additional functional components than depicted in FIG. 1. Additionally, or alternatively, one or more components of the network architecture (100) may perform functions described as being performed by one or more other components of the network architecture (100).
[0054] FIG. 2 illustrates an exemplary representation (200) of a proposed system (124), in accordance with an embodiment of the present disclosure.
[0055] Referring to FIG. 2, the system (124) may include one or more processor(s) (202). The one or more processor(s) (202) may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, logic circuitries, and/or any devices that process data based on operational instructions. Among other capabilities, the one or more processor(s) (202) may be configured to fetch and execute computer-readable instructions stored in a memory (204) of the system (124). The memory (204) may be configured to store one or more computer-readable instructions or routines in a non-transitory computer readable storage medium, which may be fetched and executed to create or share data packets over a network service. The memory (204) may comprise any non-transitory storage device including, for example, volatile memory such as random-access memory (RAM), or non-volatile memory such as erasable programmable read only memory (EPROM), flash memory, and the like.
[0056] In an embodiment, the system (124) may include an interface(s) (206). The interface(s) (206) may comprise a variety of interfaces, for example, interfaces for data input and output devices (I/O), storage devices, and the like. The interface(s) (206) may facilitate communication through the system (124). The interface(s) (206) may also provide a communication pathway for one or more components of the system (124). Examples of such components include, but are not limited to, a database (208).
[0057] In an embodiment, the processor (202) may determine one or more connected ports among one or more ports (102-A, 102-B, 102-N) based on detection of a minimum voltage across the one or more connected ports. The processor (202) record information associated with the one or more connected ports in the database (208). At least one switch among the one or more switches (108-A, 108-B, 108-N) may be configured by the processor (202) with each of the one or more ports (102-A, 102-B, 102-N) to sequentially activate one or more priority ports among the priority list of ports and power a remote device.
[0058] In an embodiment, one or more diode bridges may be configured by the processor (202) with each of the one or more ports (102-A, 102-B, 102-N) to receive a power input via the standard RJ45 Ethernet cable using a PoE technology. The one or more diode bridges (104-A, 104-B…104-N) may be configured to work with any polarity of power input received from the one or more connected ports. The processor (202) may distribute the power input to the remote device based on the sequential activation of the one or more priority ports by the processor (202). The one or more ports (102-A, 102-B, 102-N) may be connected using Ethernet cables of different lengths connected to the customer premises. Usually upon combining the power inputs from the one or more ports (102-A, 102-B, 102-N) may lead to a maximum power drawn from a connected port which has the highest potential difference among the other ports, i.e. maximum power will be drawn from the port with the least cable length. Consequently, the customer with the least cable length may be encumbered to pay for the entire broadband system operation. Hence, the processor (202) may use a time-based power sharing solution which would provide a fair-share of power resources among the connected customer’s input ports.
[0059] In an embodiment, the processor (202) may determine the priority list of ports among the one or more connected ports by detecting a predetermined voltage across the one or more connected ports.
[0060] In an embodiment, the processor (202) may determine if a predetermined voltage is detected across the priority list of ports. In response to a positive determination, the processor (202) may enable a Power Service Equipment (PSE) port among the priority list of ports and power the remote device through the PSE port for the predetermined period. In response to a negative determination, the processor (202) is to simultaneously power the remote device through the one or more connected ports. The system (124) may sequentially activate one or more priority ports among the priority list of ports.
[0061] In an embodiment, the processor (202) may determine if an I2C request is received from a CPU upon completion of the activation of the one or more priority ports and in response to a second positive determination process the I2C request. The processor (202) may, in response to a second negative determination, re-determine the one or more connected ports based on the detection of the minimum voltage across the one or more connected ports.
[0062] In an embodiment, the processor (202) may utilize the capacitor bank (110) for transitioning to a next active port among the one or more priority ports and power the remote device during the transition.
[0063] FIG. 3 illustrates an exemplary flow diagram representation (300) of the proposed system (124), in accordance with an embodiment of the present disclosure.

[0071] At step 314: The system (124) may determine if the voltage across the highest priority active port includes the predetermined voltage.
[0072] At step 316: In response to a negative determination from step 314, the system (124) may turn on the one or more switches (108-A, 108-B, 108-N) to the remote device and request for a change in the active port and go to step 318.
[0073] At step 318: In response to a positive determination from step 314, the system (124) may determine if the change in the active port is requested.
[0074] At step 320: In response to a positive determination from step 318, the system may turn on a next active port among the priority list of ports. The system (124) may turn on a switch among the one or more switches (108-A, 108-B, 108-N) associated with the next active port. The system (124) may generate a delay of 100 milliseconds to turn off the remaining switches among the one or more switches (108-A, 108-B, 108-N) and go to step 322.
