Description

METHOD AND SYSTEM OF ENABLING BACKHAUL DAISY CHAINING IN INTEGRATED MACRO NODE FIELD OF THE DISCLOSURE The present disclosure relates generally to the field of wireless communication systems. More particularly, the present disclosure relates to methods and systems for enabling cost effective backhaul daisy chaining support in at least one integrated macro node, wherein an integrated macro node is a 5th generation integrated macro next-generation Node B. BACKGROUND 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. Wireless communication technology has rapidly evolved over the past few decades, with each generation bringing significant improvements and advancements. The first generation of wireless communication technology was based on analog technology and offered only voice services. However, with the advent of the second-generation (2G) technology, digital communication and data services became possible, and text messaging was introduced. Third Generation (3G) technology marked the introduction of high-speed internet access, mobile video calling, and location-based services. The fourth-generation (4G) technology revolutionized wireless communication with faster data speeds, better network coverage, and improved security. Currently, the fifth-generation (5G) technology is being deployed, promising even faster data speeds, low latency, and the ability to connect multiple devices simultaneously. With each generation, wireless communication technology has become more advanced, sophisticated, and capable of delivering more services to its users. In 5G network, an integrated macro node is a 5G new radio (NR) Integrated Macro gNB (also referred herein as IMG). The IMG is a 200W high power gNB (Next-Generation Node B), which operates in macro class (typically SOW or 47dBm per antenna port) with 4 Transmitting 4 Receiving (4T4R) configuration. The IMG complements macro-level wide-area solutions requiring good coverage and limited capacity but still have extremely low latency and is particularly beneficial in rural and Sub-Urban areas. The 5G NR gNB (i.e., IMG) brings together an application layer, media access control layer (MAC layer) and baseband layer based on Baseband Processor chipset, radio frequency (RF) transceiver based on application-specific integrated circuit (ASIC) transceiver and RF front end module (RF-FEM) which includes RF High power amplifiers, Low noise amplifiers (LNA), RF switch and cavity filter— for instance all in a convection cooled passive enclosure and weighing < 18 kg. The IMG is more power efficient and cost-efficient deployment solution for low dense clutters, which is becoming the major criteria in 5G product design. Also, in 5G network, 5G base-stations (BS) are called 5G Base-station Distributed Units (gNB-DUs). Further, in 5G network, macro 5G BSs are overlaid by small cells (gNB-DUs). Moreover, generally in 5G networks to cover complete 360-degree radio frequency (RF) coverage footprint three cells/sectors/integrated macro nodes (IMGs) namely alpha, beta and gamma are installed on one telecom site / cell site, which requires individual backhaul port at a cell site switch and optical fibre cable routing at top of a tower at the telecom site. This requirement adds up to infrastructure cost for the network operator. Thus, there exists an imperative need in the art to reduce the infrastructure cost for the network operator by providing an efficient 5th generation integrated macro next-generation Node B (i.e., may be referred here as IMG), which the present disclosure aims to address. OBJECTS OF THE DISCLOSURE Some of the objects of the present disclosure, which at least one embodiment disclosed herein satisfies are listed herein below. It is an object of the present disclosure to provide a system and a method to cater the capacity of a complete site using one 10G backhaul connection on one of the three sectors of the telecom site thus resulting into efficient fibre capacity utilization of the network. It is another object of the present disclosure to provide a solution that includes a daisy chain support in Integrated Macro gNB (IMG) on 10G SFP28 interface by using cost effective 10G retimer instead of costly 10G optical PHY, wherein the 10G SFP28 is a small form-factor pluggable (SFP+) transceiver module that offers a higher bandwidth to support high-speed connectivity. It is yet another object of the present disclosure to provide capital expenditure (CAPEX) improvement per telecom site in the network by eliminating the need of an additional cell site router and additional optical fibre cable routing for
