WiFi 7 MLO
Wi-Fi 7 Multi-Link Operation (MLO) is a state-of-the-art technology that enables Wi-Fi communication to its fullest. MLO WiFi 7 transforms device communication and data exchange by allowing numerous simultaneous linkages between a single station (STA) and an Data Access. With a single AP, devices can create numerous parallel connections by utilising various frequency bands, channels, or spatial streams. By combining the bandwidth of these several channels, this cutting-edge technology produces throughput and reliability never before seen.
The advantages of MLO WiFi 7 are extensive and palpable. Increased network performance, lower latency, and higher data transfer rates are all available to users. Essential apps like virtual reality, 4K video streaming, and online gaming are substantially improved, offering a smooth and engaging experience. Moreover, complex network features like load balancing, link aggregation, and fault tolerance are made possible by MLO WiFi 7. This implies that in the event of a connection failure, the remaining links will be able to function, guaranteeing little downtime and continuous connectivity.
MLO architecture is commonly classified as either multiple-MAC MLO or single-MAC MLO. The purpose of this whitepaper is to discuss why MediaTek favours single-MAC MLO over multiple-MAC MLO in order to maximise throughput, minimise latency, and guarantee the best possible user experience.
MediaTek desire faster speeds, lower latency, and seamless connectivity, so wireless networks change. Wi-Fi 7’s Multi-Link Operation should improve it. This essay explores how MLO WiFi 7 can change Multi-Link Operation wireless experience by going deep into the technology.
Traditional wireless bottlenecks
Current Wi-Fi protocols like Wi-Fi 5 and 6 use one band, commonly 2.4 GHz or 5 GHz. These standards have limits even though they provide faster speeds than their predecessors. Performance bottlenecks can be caused by increased network congestion, interference from nearby networks, and restrictions on specific bands. AI Applications that need lots of bandwidth and minimal latency suffer:
Virtual Reality (VR) and Augmented Reality (AR)
Low latency in real-time data transport is essential for VR and AR immersion. Traditional Wi-Fi may not be able to meet these demands, leaving users dizzy.
Cloud gaming
To ensure fluid gameplay, streaming high-resolution games need a large amount of bandwidth and low latency. Lag and buffering break the immersion and ruin the experience.
4K/8K Video Streaming
Conventional Wi-Fi may not be able to keep up with the higher resolutions offered by streaming services, which might cause buffering and jerky viewing.
Emerging Technologies
Applications such as the Metaverse of the future will need stable, low-latency Wi-Fi to work effectively.
How MLO Transforms Wi-Fi 7
In MLO WiFi 7 is the game-changer. It enables simultaneous connections and data transmission between devices over a variety of bands and channels. Compare a single-lane road to a multi-lane motorway. This multi-lane environment is created by MLO WiFi 7, which also greatly improves overall data throughput and decreases congestion. This is how it operates:
Multi-Link Connections
Access points (APs) on different bands can be connected to simultaneously by MLO-enabled devices, also known as Multi-Link Devices (MLDs). An MLD might, for instance, be connected to the 2.4 GHz band for simple functions and the 5 GHz band for high-bandwidth operations such as streaming videos. This makes it possible to use the resources that are available and balance loads effectively.
MLO provides two operating modes
Non-STR (NSTR) and Simultaneous Transmission and Receive (STR). Independent data transmission and reception over several links at the same time is possible because to STR. This reduces latency and increases throughput, which is especially useful for real-time applications like cloud gaming and virtual reality.
Improved Reliability and Link Switching
By providing several channels for data transfer, MLO creates a stronger connection. The data can easily transition to another band in the event of interference, guaranteeing continuous communication. This is essential to keeping a steady and dependable connection for important applications.
What is MLO in WiFi 7
The acronym for Multi-Link Operation is MLO. The ability for devices to simultaneously connect to various Wi-Fi bands and channels is a crucial feature of Wi-Fi 7. There are two ways in which this can greatly enhance your Wi-Fi experience:
Enhanced Speed: MLO can efficiently increase your overall data transfer rate by utilising numerous connections at once. Consider utilising two lanes of traffic rather than just one to download a file!
Decreased Lag: MLO also aids in the control of Wi-Fi network congestion. MLO can move data traffic to a less popular band when one band fills up, which improves performance, particularly for lag-sensitive apps like online gaming and video conferencing.
Advantages of WiFi 7 MLO
MLO is perfect for a range of applications because it offers notable benefits over conventional MLO WiFi 7. These benefits include:
Unprecedented Speeds
Compared to earlier Wi-Fi standards, MLO WiFi 7 can achieve much greater data transfer rates by pooling bandwidth from many bands. This results in more responsive network performance overall, faster downloads, and seamless streaming.
Ultra-Low Latency
MLO reduces latency by enabling simultaneous data transmission and reception across several channels. This is especially helpful for real-time applications like virtual reality, cloud gaming, and video conferencing, where even little delays can have negative effects.
Enhanced Network Efficiency
MLO distributes data intelligently among available links to optimise network traffic. This makes the network less congested and guarantees effective use of its resources, improving the overall experience for all linked devices.
Enhanced Reliability
MLO provides a more reliable connection by providing numerous paths for data delivery. Data may easily transition to another frequency in the event of interference, reducing disruptions and guaranteeing reliable communication.
Future-Proofing Technology
MLO opens the door for the upcoming wave of bandwidth-demanding apps, such as AR/VR experiences and the Metaverse. It is a vital enabler for upcoming technological developments due to its low latency and capacity to manage large data needs.
MLO: Obstacles and Things to Think About
Even if MLO is a huge advancement, there are still certain issues that must be resolved:
Hardware Compatibility
MLO requires MLDs and MLO-enabled APs to be compatible devices on both ends. Since MLO WiFi 7 is a new standard, it will take some time for MLO-compatible devices to become widely used.
Network Complexity
Complex network management software is needed to maintain numerous connections and guarantee a smooth handoff between bands. For residential users, this could provide difficulties and require knowledge for the best setting.
