What is OFDMA (Orthogonal Frequency Division Multiple Access)? OFDMA is a multi-user version of the OFDM digital-modulation technology. In Wi-Fi 6 (802.11ax), OFDMA is one of the critical feature to improve network performance. Both OFDM and OFDMA split transmitted data into several small pack...
How does OFDMA work? One way to understand OFDMA is to use delivery trucks as an analogy. With Wi-Fi 5, each "truck" could carry only a single user's cargo. But with Wi-Fi 6 and OFDMA, the truck can be loaded with multiple users' cargo loads. Also, its drop-off schedule can be...
Orthogonal Frequency Division Multiple Access (OFDMA) is a new technology introduced into Wi-Fi 6. It greatly improves the spectrum utilization and WLAN performance.

上行和下行的技术选址不一样,主要是终端和基站相比能力有限,特别是功率受限。 还有一个优点是SC-FDMA可以灵活支持Distribute FDMA 和Localized FDMA,灵活性接近OFDMA。 当然:虽然SC-FDMA的PAPR远低于OFDMA,但是sc-fdma的频谱效率也低于OFDMA。反馈 收藏

Many think that by stipulating a new modulation method called Scalable OFDMA (SOFDMA), 802.16-2005 will SOFDMA will improve upon OFDM256 for NLOS applications by: SOFDMA and OFDMA256 are not compatible so most equipment will have to be replaced. WiMAX--future comms? More results ► Acronyms...
How do I choose? WiFi 6 vs WiFi 6E vs WiFi 7? Wi-Fi 7 (IEEE 802.11be) is a generational leap in wireless connectivity that boasts a data rate of up to 46 Gbps, 100x Lower Latency and 5x Network Capacity. Learn more about your WiFi speed!
