Emphasis is placed on the technical lineage of air interfaces—progressing from FDMA and analog FM to TDMA, CDMA, OFDMA, and massive MIMO—and situates these innovations within the broader contexts of spectrum allocation, propagation fundamentals, and regulatory policy frameworks across ASEAN, APAC, Europe, and ANZ. Topological perspectives are integrated, encompassing macro, micro, PICO, FEMTO, LPWAN, ad hoc, and satellite constellation architectures. The study details the progression of core network technologies, from circuit-switched Mobile Switching Centers (MSCs) to 5G Service-Based Architectures (SBA) and the advent of AI-native cores. Security and authentication mechanisms receive special focus, tracing the shift from legacy analog protocols to modern SIM-based authentication, mutual AKA, eSIM provisioning, SUCI identifier protection, and quantum-safe, forward-looking approaches. Comparative case studies of deployments in Singapore, Malaysia, Japan, and Europe illuminate how local geography, regulation, and socio-economic conditions have shaped divergent paths of technology adoption. Special systems—including TETRA for mission-critical voice, LoRaWAN for IoT, satellite backhaul (LEO/MEO/GEO), WiMAX, Wi-Fi, Bluetooth, ZigBee, and UWB—are examined for their technical and operational trade-offs. An addendum develops the Smart Nation case study, highlighting Singapore’s PSA Tuas Mega Port, autonomous vehicles, and urban IoT ecosystems as precursors for advanced research into smart infrastructures. The thesis also addresses the integration of Artificial Intelligence and Data Science,

Ultimately, the work argues that the progression of mobile and wireless systems is not merely a pursuit of speed, but a convergence of communication, computation, and control, underpinning the Fourth Industrial Revolution. Concluding with a forward-looking perspective, the thesis discusses developments in 5G-Advanced and 6G research, including sub-THz spectrum, reconfigurable intelligent surfaces (RIS), integrated sensing and communication (ISAC), and post-quantum security, positioning this work as both a technical record and a strategic roadmap for future scholarly and industrial exploration.

From the humble beginnings of analog cellular telephony in the 1980s (1G) to today’s highly sophisticated 5G networks and the research frontier of 6G, mobile and wireless technologies have fundamentally reshaped the global economy, connectivity paradigms, and the nature of human interaction. This thesis presents a comprehensive engineering-oriented overview of mobile and wireless radio systems, emphasizing their technical evolution, underlying architectures, and deployment topologies , while integrating perspectives from data science, artificial intelligence (AI), and machine learning (ML). The study addresses both historical context and forward-looking perspectives , incorporating systems such as Wi-Fi, WiMAX, LoRaWAN, TETRA ATEX radios, ST GRID devices, and non-terrestrial networks including satellite constellations such as Beidou, Gouwang, Qianfan, Starlink, and Inmarsat. It also provides a comparative regional analysis focusing on ASEAN (Association of Southeast Asian Nations) and ANZ (Australia and New Zealand) markets, where diverse geographic, demographic, and regulatory conditions have shaped unique deployment trajectories. The relevance of this topic is manifold. From an engineering standpoint , the radio technologies that underpin mobile networks illustrate the interplay between spectrum allocation, modulation techniques, hardware capabilities, and topological design. From a data science and AI perspective , modern networks have become too complex to manage solely through human intervention; they rely increasingly on autonomous optimization, predictive analytics, and AI-native architectures . From a socio- economic angle , mobile and wireless networks have become essential infrastructures— particularly evident during the COVID-19 pandemic when connectivity underpinned remote work, education, and healthcare.

The earliest way of communicating was using MORSE CODE through low band frequencies across the Atlantic thanks to WW2 where early German Enigma machine cause heavy casualties to the allied forces. The evolution of mobile communication networks from the 1980s to the present has been marked by a sequence of “generational leaps” defined by standardization bodies such as the International Telecommunication Union (ITU) and the 3rd Generation Partnership Project (3GPP) . Each generation (1G, 2G, 3G, 4G, and 5G) introduced new radio access technologies, modulation schemes, network architectures, and service paradigms , with 6G already emerging as a research frontier. These generational shifts were not merely technological; they were shaped by regulation, spectrum availability, socio-economic factors, and hardware capabilities . The following sections trace this timeline in detail, highlighting technical characteristics, socio-economic impacts, and the role of AI and data science in shaping or analyzing each phase.

It is not consumable like fuel, but it is scarce and subject to strict allocation, regulation, and reuse strategies. Unlike other resources, spectrum cannot be manufactured; it must be efficiently shared and reused using frequency planning, modulation efficiency, and multi-access schemes. The management of spectrum has been overseen globally by the International Telecommunication Union (ITU) , while national regulators such as ACMA (Australian Communications and Media Authority) , IMDA (Singapore) , NBTC (Thailand) , and others in the ASEAN region enforce localized frameworks. Spectrum licensing, auctions, and refarming are key mechanisms through which governments allocate frequencies to operators. 5.2 The Importance of the 900 MHz Band The 900 MHz band has historically played a central role in mobile communications: 1G: Many early analog systems operated at 900 MHz. 2G GSM: 900 MHz was the global anchor band, offering balance between coverage and capacity. 3G UMTS: Some refarming allowed deployment of 3G in 900 MHz. 4G LTE: Operators in ASEAN/ANZ reused 900 MHz for LTE coverage in rural areas. 5G NR: While primarily sub-6 GHz and mmWave, some early deployments use refarmed 900 MHz for coverage-layer NR.

Generates government revenue but may increase operator costs → higher end- user tariffs. 5.6.2 Administrative Assignment Seen in some ASEAN countries with less mature regulatory markets. Spectrum directly assigned to incumbents. 5.6.3 Unlicensed Spectrum ISM bands (2.4 GHz, 5 GHz, 6 GHz) widely used for Wi-Fi and LoRaWAN. ASEAN has mixed adoption of 6 GHz Wi-Fi 6E. ANZ allows wider unlicensed use due to advanced regulatory frameworks. 5.6.4 Shared Spectrum Models CBRS (Citizens Broadband Radio Service) -style models in the US inspire ASEAN/ANZ regulators. Potential use of shared spectrum for private 5G/IoT deployments.

ANZ Example: Telstra and Optus shut down 2G by 2016–2017, refarming spectrum to LTE. Refarming balances backward compatibility with forward innovation. 5.7.1 ASEAN Spectrum Landscape ASEAN nations are diverse in spectrum usage: Singapore (IMDA): Aggressive 5G rollout in 3.5 GHz and mmWave. 900 MHz used for LTE fallback. Malaysia (MCMC): Single Wholesale Network for 5G (controversial). Thailand (NBTC): Multi-band 5G auctions (700 MHz, 2600 MHz, 26 GHz). Indonesia: Large geography, limited 3.5 GHz spectrum availability → reliance on 1800/2100 MHz refarming. Philippines: New entrant Dito Telecommunity licensed in 700 MHz for coverage. Challenges: Fragmented policies across countries. High auction fees vs. affordability pressures. Legacy 2G networks still operational in some regions.
Page 35
© AZRIN.INFO 2025 UNIVERSITA’ DEGLI GUGLIELMO MARCONI Page 36 of 114 5.7.2 ANZ Spectrum Landscape Australia and New Zealand benefit from more coordinated spectrum planning . Australia (ACMA): o 700 MHz (“digital dividend”) allocated for LTE and 5G. o 3.6 GHz allocated to 5G. o mmWave auctions (26 GHz) completed in 2021. New Zealand (MBIE): o 600 MHz, 700 MHz for rural LTE/5G. o 3.5 GHz as the primary 5G band. Unique features: Large landmass → heavy reliance on low-band spectrum for rural coverage. Early adoption of satellite augmentation (Starlink, Inmarsat) to fill coverage gaps. 5.8 Sub-THz and mmWave Challenges While mmWave (24–40 GHz) offers extreme bandwidth, coverage limitations are significant: Propagation Loss: Free-space path loss increases 6 dB per frequency doubling. Penetration Loss: High absorption through walls, foliage, even rain. Deployment Cost: Requires dense small-cell infrastructure. ASEAN context: Dense cities like Singapore may benefit. Rural ASEAN less suitable. ANZ context: Limited mmWave beyond urban hotspots due to geography. Sub-THz for 6G introduces further challenges: atmospheric absorption, hardware cost, regulatory uncertainties.

Dynamic Spectrum Sharing (DSS): Used to allow LTE and 5G coexistence in same band. Satellite-Terrestrial Convergence: New ITU allocations for non-terrestrial networks (NTN) under 5G NR. AI for Spectrum Management: Cognitive radio and ML-driven spectrum sensing proposed for 6G. 5.10 Summary Spectrum regulation has been both an enabler and bottleneck of mobile technology evolution. The 900 MHz band exemplifies the continuity of spectrum reuse, while higher bands (3.5 GHz, mmWave) reflect the demand for capacity. ASEAN’s fragmented policies contrast with ANZ’s coordinated planning, yet both regions demonstrate innovation in refarming, auctions, and satellite integration. AI and Data Science will increasingly be used for dynamic spectrum allocation, interference detection, and demand prediction , making spectrum management not only a regulatory challenge but also a computational one.

While 1G networks offered virtually no protection against eavesdropping and fraud , today’s 5G networks provide end-to-end encryption, mutual authentication, and subscriber privacy mechanisms. However, each generation introduced new attack surfaces : cloning in 1G, weak ciphers in 2G, signaling storms in 3G, IMS vulnerabilities in 4G, and virtualized network security risks in 5G. Looking ahead, AI/ML-enhanced security frameworks are expected to underpin 6G. 10.2 1G: Insecure Beginnings Analog FM voice: No encryption, easily intercepted by scanners. Authentication: None; phone cloning rampant (copying ESN/IMSI). Vulnerabilities: o Fraudulent calls billed to victims. o Eavesdropping in sensitive scenarios (e.g., law enforcement). 10.3 2G: Basic Digital Security Authentication and Encryption SIM-based authentication: Introduced secret key (Ki) stored in SIM and AuC. A3/A8 algorithms: Generate session key (Kc). Ciphering: A5/1, A5/2 stream ciphers. Weaknesses A5/1 eventually cracked with rainbow tables.

Across ASEAN and ANZ, the comparative analysis demonstrated that technology adoption reflects regional socio-economic and geographic realities : ASEAN megacities → dense LTE/5G rollouts, smart city integration. ANZ rural/remote regions → satellite and hybrid systems critical for inclusion. 17.2 Key Findings 17.2.1 Generational Progression 1G: Introduced cellular concept, but no security. 2G: Digitalization, SMS culture, basic security. 3G: Mobile broadband foundation, yet uneven global adoption. 4G LTE: All-IP, high capacity, foundation for the gig economy. 5G NR: AI-ready, ultra-low latency, slicing, satellite integration. 17.2.2 Specialized Systems LoRaWAN: Ideal for long-range IoT, but limited throughput. TETRA ATEX / ST GRID: Mission-critical, ruggedized comms for safety industries. Satellite Systems: Complement terrestrial, crucial for rural ANZ and disaster- stricken ASEAN.
