MediaTek, one of the first adopters of Wi-Fi 7 technology, now has the industry's most comprehensive Wi-Fi 7 portfolio with today's introduction of the company's new Filogic 860 and Filogic 360 solutions. Together, these second-generation additions aim to further expand MediaTek's platform of cutting-edge products that utilize the latest technology advancements in connectivity while achieving peak performance and always-on reliability.

Filogic 860 combines a Wi-Fi 7 dual-band access point with a new advanced network processor solution and is ideal for enterprise access points, service provider Ethernet gateways and mesh nodes, as well as retail and IoT router applications. Filogic 360 is a stand-alone client solution that integrates Wi-Fi 7 2x2 and dual Bluetooth 5.4 radios in a single chip, and is designed to deliver next-generation Wi-Fi 7 connectivity to edge devices, streaming devices and a vast array of other consumer electronics.




"MediaTek stands out with the most comprehensive connectivity portfolio on the market, and we're continuing this legacy with our two new advanced Wi-Fi 7 solutions designed for mainstream applications," said Alan Hsu, corporate vice president and general manager of the Intelligent Connectivity Business at MediaTek. "Filogic 860 and Filogic 360 offers the same technology as our premium solutions with exceptional reliability in busy network environments, ultra-fast speeds with reduced latency and enhanced range."

For the enterprise and retail markets, Filogic 860 provides a complete platform for a dual-band Wi-Fi 7 access point, router and mesh node solution. Building upon the success of its first-generation design, Filogic 860 is equipped with a triple-core Arm Cortex-A73 CPU that supports powerful hardware acceleration for advanced tunneling and security features to meet enterprise, service provider requirements.

The Filogic 860 platform includes with the following features:
  • Industry leading 6 nm low power Wi-Fi design
  • Single-MAC MLO support
  • Supports 4096-QAM and MRU
  • Supports dual-band Wi-Fi 7 with industry-highest dual-band MLO speed, 7.2 Gbps
  • Dual-band, dual concurrent capabilities with 4T4R for 2.4 GHz up to BW40 and 5T5R 4SS for 5 GHz up to BW160
  • Support for an additional receive antenna for zero-wait DFS
  • Filogic Xtra range support, boosting receiving distance using an extra antenna

The Filogic 360 is a stand-alone, single chip Wi-Fi 7 2x2 and dual Bluetooth 5.4 solution designed to deliver best-in-class connectivity for high-performance clients such as smartphones, PCs, laptops, set-top boxes, OTT streaming, and many other devices.

Key features of the Filogic 360 include:
  • Triple-band selectable Wi-Fi 7 2x2 with up to 2.9 Gbps speed
  • Supports 4096-QAM and MRU
  • 160 MHz channel bandwidth support
  • Filogic Xtra range support, boosting communication distance by unique Hybrid MLO solution
  • Support for dual Bluetooth 5.4 cores for gaming and other applications
  • BLE audio with integrated DSP for LC3 codec support
  • MediaTek advanced Wi-Fi and Bluetooth coexistence technology ensures both technologies can operate on the 2.4 GHz band seamlessly, without interference

The MediaTek Filogic 860 and Filogic 360 solutions have begun sampling to customers and mass production is anticipated for mid-2024.

I see the channel Bandwidth has not been increased vs Wifi 6. It will be interesting to see how this format performs vs Wifi 6.

In what sense? You get 320 MHz wide channels and the QAM has gone from 1024 to 4096, so clearly the bandwidth has increased.
The 2.4 GHz band is pretty limited already, so not much that can be done to improve performance there.

Small speed but not guaranteed. Perfect.
At least it's the top sync speed people can expect on their devices, due to most devices only being 2x2.

I wonder how these are doing compared to qualcomm/broadcom, etc.?

Qualcomm has Fastconnect-7800, Max advertised speed is 5.8 Gbps (double 4k QAM/320Mhz ?). But it also supports 320Mhz, which these mediatek's don't.
Mediatek says it's 7.2 Gbps, but it also says 5T5R 4SS (5 Transmitting antennas, 5 Receiving antennas, 4 Spatial Streams) which is I guess is 4 streams of 4k QAM/160Mhz, but isn't it basically trash? Don't you want the max bandwidth with as few antennas as possible, for which you want 320Mhz?
And how are they getting 7.2 Gbps with only 4 Spatial Streams? 4 steams of 4k/160 should add up to 5.8 gbps (1441*4), 4k/40 of 2.4Ghz is only 360mpbs, it needs 1 more stream of 4k/160 for numbers to add up. Some gimmick tech again to utilize the extra antennas somehow? Oh, maybe 4 streams of 2.4Ghz too? It does add up to 1441mpbs.

Can someone explain how it works please? I've read up on Wifi7, but it still unclear.

Keep in mind that this is MTK's mainstream platform. The flagship is the Filogic 880.

As for your other question, MLO allows you to combine the bandwidth of the different frequency band into a single, faster data stream. Not sure how well it'll work in real world usage, nor sure why it's needed.
