The Mobile World Congress (MWC) 2025, taking place from March 3 to March 6 in Barcelona, Spain, has attracted global attention, showcasing the latest advancements and product innovations from leading technology companies such as Xiaomi and Viettel. This year’s Congress emphasizes sustainable technological solutions aimed at enhancing connectivity and addressing global challenges.
Among the standout presentations was Xiaomi's introduction of the ambitious Xiaomi Modular Optical System. While currently still in the concept phase, this system aims to revolutionize smartphone photography. It allows users to attach a detachable camera module featuring a large sensor and professional-level zoom lens to the back of the smartphone. This unique design employs a magnetic mechanism similar to Apple's MagSafe technology, ensuring ease of use and fast attachment.
The innovative modular concept utilizes the Light Fusion X Micro Four Thirds sensor, boasting an impressive 100MP resolution paired with a 35mm f/1.4 lens. The design reassures users by allowing for adjustable aperture settings ranging from f/1.4 to f/11, enhancing image quality by enabling more light capture and delivering professional depth of field comparable to DSLR cameras.
A notable feature of the system is the Xiaomi LaserLink technology, which facilitates ultra-fast RAW data transmission within nanoseconds, ensuring images are processed swiftly without latency. This technology not only sets Xiaomi's offering apart from previous detachable camera systems, such as Sony's QX100 and Xiaomi’s own 12S Ultra Concept, but potentially places Xiaomi at the forefront of photographic innovation.
Upon attachment, the camera module seamlessly connects with Xiaomi’s photography application, providing users immediate access to enhanced shooting features, making the user experience smooth and intuitive. Users also benefit from various Leica modes built-in from previous flagship models, capitalizing on Xiaomi's advanced image processing capabilities. The modular camera system operates without any need for installation or setup, allowing for quick detachment and use, which supports the modern mobile lifestyle.
Despite its enticing proposition, the Xiaomi Modular Optical System remains conceptually developed and has no confirmed go-to-market date. Xiaomi is currently gathering user feedback to determine the product's commercial viability. Historically, other companies like Sony and Motorola have attempted modular camera systems with varying degrees of success, but if anyone can make this concept commercially successful, it may just be Xiaomi.
On the other hand, Vietnamese telecommunications giant Viettel marked its presence at MWC 2025, showcasing 22 innovative products spanning across 5G infrastructure, digital platforms, and application development. This year, Viettel is the sole representative from Vietnam and has themed its presentation around technological creativity for sustainable development.
The company's offerings include scalable solutions aimed at enhancing connectivity, managing data effectively, and providing advanced applications for businesses and users. Viettel's product lines are categorized under three main groups: network infrastructure, digital platforms, and digital applications, all crafted to streamline operations and improve user experiences.
