In 2024, Wi-Fi 7 technology will be integrated into gadgets, boasting unique features and significant improvements over its predecessors. Notably, Wi-Fi 7 operates without needing the 6GHz spectrum bands, ensuring superior performance through various other spectrum bands. This development has sparked debates among telecom and broadband companies regarding allocating the 6GHz spectrum band.
In response to these discussions, Qualcomm, a leading semiconductor and software company, has advocated adopting Wi-Fi 7 technology over Wi-Fi 6E. Wi-Fi 7 functions seamlessly on alternative spectrum bands, eliminating the requirement for 6GHz bands. Qualcomm emphasizes that Wi-Fi 7 delivers not only superior speeds and faster data transfers but also reduces latency speeds by 60% compared to Wi-Fi 6E.
Rahul Patel, Qualcomm’s Senior Vice President and General Manager for Connectivity, Broadband, and Networking, has discouraged the adoption of Wi-Fi 6E in India, citing the unallocated 6GHz spectrum band as a significant reason. Patel suggests that transitioning directly to Wi-Fi 7 would be a strategic move for future planning. Wi-Fi 7 boasts unique features that make it independent of the 6GHz band. This technology supports carriage aggregation, allowing it to utilize a mix of different spectrum frequencies, ensuring uninterrupted internet connectivity. Qualcomm envisions more than 350 products shipping with Wi-Fi 7 capabilities by the first half of 2024.
Furthermore, Wi-Fi 7, also known as IEEE 802.11be Extremely High Throughput, promises significant advancements over previous standards. It introduces wider channels, expanding up to 320 MHz in the 6GHz spectrum, doubling the throughput compared to Wi-Fi 6E. This expansion in channel size results in a theoretical maximum transfer rate of 30 Gbps per access point, making it approximately four times faster than Wi-Fi 6. Lower latency and reduced lag are achieved through technologies like coordinated beamforming and parameterized spatial reuse. Additionally, Wi-Fi 7 incorporates Multi-Link Operation (MLO), enabling the simultaneous use of multiple sets of frequencies, boosting data transfer speeds, and reducing latency.
Automated Frequency Coordination (AFC) ensures efficient spectrum utilization, increasing signal strength and connection reliability. Another feature, 4K Quadrature Amplitude Modulation (4K QAM), enables higher data transmission within the same signal, enhancing overall efficiency and performance.
As Wi-Fi 7 technology becomes widely available in gadgets, users can expect a more stable, faster, and more efficient internet experience, supporting various applications, including augmented reality, virtual reality, gaming, and high-quality video streaming. The transition to Wi-Fi 7 represents a significant leap forward in wireless connectivity, enhancing the capabilities of smart home devices and supporting the growing demands of modern digital experiences.
