The owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all rights whatsoever. All rights to such intellectual property are fully reserved by the owner. TECHNICAL FIELD [002] The present disclosure relates to wireless cellular communications, and specifically to a system and a method for providing a 5G New Radio (NR) Pico Small Cell (PSC). BACKGROUND [003] The following description of 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 be used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of prior art. [004] In prevalent times wireless coverage and capacity inside a building has substantial importance. As per analytics people spend 80-90% of their time indoors, while 70% of cellular calls and 80% of data connections originate from the indoors, such as in an office, a residence, a mall, a hotel, a hospital, and a school, etc. Many indoor locations are very complicated in structure, and it is very difficult to penetrate a macro cell tower coverage from an outdoor location to an indoor location. A dedicated indoor solution i.e. a Distributed Antenna System (DAS) is recommended for large venues. The DAS is an array of antennas strategically placed throughout an indoor facility that distributes a coverage area of the large venues into smaller sections using a network of interconnected antennas. A Quality of Service (QoS) based indoor coverage is more significant since most mobile data consumption takes place indoors. However, meeting coverage and capacity requirements comes at a high cost and has serious performance issues. [005] There is therefore a need in the art to provide a Pico Small Cell (PSC) that provides a good network coverage and fulfils capacity requirements at an effective cost. OBJECTS OF THE PRESENT DISCLOSURE [006] It is an object of the present disclosure to provide a 4 Transmitter 4 Receiver (4T4R) Fifth Generation (5G) New Radio (NR) Pico Small Cell (PSC).

[009] It is an object of the present disclosure to provide the 4T4R 5G NR PSC that has a low power consumption and is thermally handled properly by an Ingress Protection (IP) 65 mechanical housing with heat pipes. [0010] It is an object of the present disclosure to provide the 4T4R 5G NR PSC that supports a zero touch, a plug-and-play integration process, and a selforganizing network (SON) features.

The 4T4R 5G NR PSC includes an Integrated Baseband and Transceiver Board (IBTB) with a clock section including a plurality of system synchronizers configured based on at least one of a Global Positioning System (GPS), a Precision Time Protocol (PTP) and a holdover. The 4T4R 5G NR PSC includes a Radio-Frequency Front End Board (RFEB) configured to connect with the IBTB to provide a pre-defined output.
