Core Viewpoint - Apple is reportedly considering introducing 5G cellular connectivity for its MacBook series, with potential mass production as early as 2026 [1][5]. Group 1: Historical Context - Apple had previously developed a prototype with 3G connectivity back in 2007, which featured a sleek retractable antenna but was never released [3]. - After the initial prototype, Apple did not pursue cellular-enabled MacBooks for a long time [3]. Group 2: Technological Developments - Recent rumors suggest that Apple's renewed interest in cellular connectivity for MacBooks is largely due to advancements in its second-generation self-developed 5G modem, referred to as the C2 chip, which supports both Sub-6GHz and mmWave 5G networks [5]. - The mmWave technology is noted for its superior peak speeds and performance in densely populated areas compared to Sub-6GHz networks [5]. Group 3: Market Landscape - Other manufacturers have already introduced laptops with 5G connectivity, utilizing early hybrid architecture processors and external 5G modems since around 2020 [7]. - Currently, major companies like Intel, AMD, and Qualcomm rely on external modems for 5G connectivity in laptops, rather than integrating them directly into the main chip [9][10]. Group 4: User Behavior and Market Demand - The limited adoption of laptops with built-in 5G connectivity can be attributed to user behavior, as many users primarily use laptops in fixed locations rather than on the go [16]. - Additionally, laptops with built-in cellular capabilities often come with substantial data packages, which are necessary to make them competitive against mobile hotspots and Wi-Fi [18].
