Malaysia has made considerable progress in its 5G network rollout, with Digital Nasional Berhad (DNB) successfully completing 7,114 5G sites across the country, covering 81.7% of populated areas.
However, expansion into other areas, including rural regions, has begun and will continue periodically. “In Kuala Lumpur, 5G coverage in populated areas is at 97.7%, Putrajaya at 97.3%, Selangor at 96.1%, Johor at 83.1%, Melaka at 88.6%, Negeri Sembilan at 77.5%, Penang at 91.1%, and Perak at 79.8%,” she said during Question Time.
The path forward for Malaysia's 5G deployment hinges on critical policy decisions. These include determining whether to maintain a government golden share in DNB, conducting open tenders for remaining coverage areas and indoor solutions, and exploring financing models for rural deployment.
Digital Nasional chief executive officer, Augustus Ralph Marshall, said that the country's first 5G base station installation at Bukit Tunku has been powered on which aims to deliver 500 5G-enabled sites in Kuala Lumpur, Cyberjaya and Putrajaya upon rollout.
5G base stations operate by using multiple input and multiple output (MIMO) antennas to send and receive more data simultaneously compared to previous generations of mobile networks. They are designed to handle the increased data traffic and provide higher speeds by operating in higher frequency bands, such as the millimeter-wave spectrum.
5th generation wireless systems, or 5G, may use existing 4G or newly specified 5G Frequency Bands to operate. Technologies include: Millimeter wave bands (26, 28, 38, and 60 GHz) are 5G Massive MIMO, "Low-band 5G" and "Mid-band 5G" use frequencies from 600 MHz to 6 GHz, especially 3.5-4.2 GHz.
5G New Radio (NR) base stations, also known as gNBs, are classified into different types based on their deployment scenarios, frequency ranges, and technical requirements. Here's a detailed technical explanation of the various 5G NR base station types: 1. Classification by Frequency Range
In 5G systems, service providers are planning to use bandwidth of 500MHz to up to 1-2 GHz. Sub-6 GHz spectrum is the candidate for the early deployment of 5G networks globally. It will use unused spectrum below the 6GHz range; it can support higher bandwidth than LTE frequency bands.
5G networks divide coverage areas into smaller zones called cells, enabling devices to connect to local base stations via radio. Each station connects to the broader telephone network and the Internet through high-speed optical fiber or wireless backhaul.
In 5G, base stations are known as gNB, where the “g” stands for next Generation. The Mobile Core is a bundle of functionality (conventionally packaged as one or more devices) that serves several purposes. Provides Internet (IP) connectivity for both data and voice services. Ensures this connectivity fulfills the promised QoS requirements.
5G Base Stations: Compared to 4G base stations, 5G brings higher data throughput and power density, significantly increasing heat generation. Therefore, the performance requirements for thermal materials are much higher. ● Small/Micro Base Stations: These base stations are compact, with limited space, making thermal design more challenging.
Major suppliers of 5G radio and core systems included Altiostar, Cisco Systems, Datang Telecom/Fiberhome, Ericsson, Huawei, Nokia, Qualcomm, Samsung, and ZTE. Huawei was estimated to hold about 70 percent of global 5G base stations by 2023.
