Yamaha Wireless LAN's new flagship model "WLX413" seen from four Kodawari

Faster: Supports Wi-Fi 6 Tri-Band and 10GBASE-T

Now, regarding the WLX413, Yamaha has inherited the approach that emphasized access points. there is

The concept is "faster, more, wider, more convenient". Let's look at these four in turn.

The first is faster. The WLX413 is the first Yamaha access point to support Wi-Fi 6 (IEEE 802.11ax). Moreover, unlike the WLX402 (previous high-end model), which supported Wi-Fi 5 (IEEE 801.11ac) dual-band, it supports two 5GHz bands and a tri-band 2.4GHz band. The throughput of the entire device is a total of 5.9 Gbps (theoretical value).

Wi-Fi 6 tri-band support greatly exceeds gigabit throughput performance for wireless LANs, so wired LAN interfaces can also use 10GBASE-T or 2.5GBASE-T/ It supports high-speed Ethernet such as 5GBASE-T.

Currently, many Wi-Fi 6 access points on the market are equipped with 2.5GBASE-T and 5GBASE-T interfaces, and many models do not support 10GBASE-T. It would be an exaggeration to say that there is not much difference, but there is not much difference in what should be done.That is why we adopted 10GBASE-T, partly because it is our flagship,” said Shinkawa.

Also, some network switches support 10GBASE-T and 1000BASE-T, but not 2.5GBASE-T or 5GBASE-T. Then, we made it compatible with 10GBASE-T,” says Shinkawa.

In addition, the WLX413 also emphasizes short frame (short packet) performance. This is because the use of teleconferencing is expanding as corporate work styles change significantly due to the corona crisis, but from the perspective of ensuring real-time performance, teleconferencing uses short frames for communication. However, the processing of short frames is a heavy burden on the network equipment responsible for relaying data, and smooth processing is required for comfortable remote conferences.

Therefore, Yamaha has improved the short frame performance of the WLX413 compared to conventional products. In order to demonstrate this, the company actually measured and compared the short frame transfer processing performance of WLX413 and WLX402 (previous generation high-end model) and published it as a technical document. According to it, the performance of WLX413 is about three times that of WLX402 in short frame transfer performance.

In addition, the WLX413 supports Fast DFS and WDS (described later), as with the tri-band compatible midrange model "WLX313".

Fast DFS is a function that prevents communication from being cut off by DFS (Dynamic Frequency Selection). The 5GHz band (excluding W52) shares the band with weather radar and aviation radar, and Wi-Fi is supposed to give up the channel when those radio waves are detected. When these radar waves are detected, it will switch to a non-interfering channel, but communication will be cut for at least 60 seconds to check it.

To prevent this, when the function is enabled, it constantly scans for channels in one of the two 5 GHz bands to find out which channels do not interfere with radar waves. When a radar wave is detected, the other band channel used for normal wireless LAN communication is quickly switched to another channel that does not interfere with the radar wave, thereby reducing the impact on communication. there is

However, when Fast DFS is enabled, stable communication becomes possible, but one band in the 5 GHz band cannot be used for wireless LAN communication, so that point is a trade-off.
