Large-capacity video services and file transfers have become the fastest growing services under the popularization of tablets and smartphones, which in turn has brought about the consumption of huge network resources. Cheap and fast Wi-Fi has become the most important The way of carrying data traffic.
As the main Wi-Fi technology that most users and enterprises rely on, 802.11n will gradually show a "powerless" situation when dealing with high-bandwidth services such as video and games under the impact of real big data.
In the innovation of wireless transmission technology, the fifth-generation Wi-Fi (802.11ac) greatly surpasses 802.11n in coverage, speed, energy consumption, etc. With higher throughput and data transmission rate, as well as single link And multi-site enhanced support is turning HD video synchronous transmission into reality on smart terminals.
As chip maker Marvell released the industry ’s first 802.11ac 4 & TImes; 4 system-on-chip (SoC), the data throughput of enterprise and retail access points (APs) and the stability of wireless video transmission have once again moved to a new level .
How to understand 802.11ac 4 & TImes; 4? According to technical experts, compared to the previous 802.11n standard, 802.11ac can already provide up to 3 times the Wi-Fi throughput and more than 2 times the power efficiency when handling high-speed loads. The new 802.11ac 4 & TImes; 4 solution improves the performance and coverage of wireless networks and greatly improves the data throughput performance of enterprise and retail access points, service provider gateways, hotspots, video bridges, and set-top boxes.
When the new technology was released, Marvell executives also said that in addition to changing the network status of enterprise-level network infrastructure and carrier-grade video applications, 802.11ac 4 & TImes; 4 will also significantly increase the network capacity of Wi-Fi devices that access cloud infrastructure, Performance and reliability further promote the popularity of 'always-on' devices, which means that content service providers will be able to provide live content to online consumers through screens of all sizes and 'smart appliances'.
In the evolution and commercialization of WLAN technology, chips play the most critical role in the entire industry chain. Since Broadcom first released the fifth-generation Wi-Fi or 802.11ac technology, mainstream chip manufacturers including MediaTek, Qualcomm Atheros, Marvell and others have successively launched related products, which has greatly shortened the 5G Wi-Fi product market cycle.
Although 802.11ac has not yet substantially entered into a wide range of application fields, but after the previous 2 × 2 802.11ac chip technology has been launched, it seems that the trend of technology-driven network performance to further improve is still accelerating. The latest 802.11ac 4 × 4 chip mentioned above will not only enable carrier-grade multi-stream HD video based on Wi-Fi networks, but also hope to provide users with high-quality, low-latency through gateways and set-top boxes introduced by service providers. Timeless, distortion-free video content.
