Wi-Fi 7 MLO: Link Switching
Introduction 802.11be aka Wi-Fi 7 is the latest Wi-Fi technology to be in the market. It offers features that can greatly enhance performance, such as 4K QAM , 320 MHz , MLO , and Preamble Puncturing . Among these, MLO can provide improvements in throughput (via link aggregation) or latency (via link switching). In this blog, we will examine link switching in detail. MLO Link Switching MLO is a technology that allows the traditional “STA” and AP to be associated with multiple links. Such devices are called Multi-Link Devices (MLDs). The name Non-AP MLD refers to the client device, and the name AP MLD refers to the AP. The links would be in different channels, typically in different bands (e.g., 2.4 GHz, 5 GHz, or 6 GHz). The mode of operation where both links are active is called MLMR (Multi-Link Multi-Radio). Multi-Link Single Radio (MLSR) is the mode in which only one link is active at a time ( Refer to blog on MLO ). The Multi-Link Client device “decides” on the fly to u...
