For example, in the case of NURO, depending on the rental equipment, the wired LAN may be 1000BASE-T with a maximum of 1 Gbps, and the wireless may be Wi-Fi 5 (IEEE 802.11ac) with a maximum of 1300 Mbps.In this case, you can make effective use of speed in terms of "even if someone is communicating to the fullest," but you cannot "fully utilize up to 2 Gbps with one PC."However, NURO Hikari also rents Sony's built-in Wi-Fi router ONU that supports wired LAN (2.5GBASE-T) of up to 2.5 Gbps and Wi-Fi 6 (IEEE 802.11ax) that can communicate at up to 4800 Mbps according to the standard. Prepared as.And as of February 2022, there is also an option plan that will definitely be rented.The option plan is "NURO Smart Life," which allows you to utilize smart home appliances such as smart locks.And Sony's built-in Wi-Fi router ONU to be rented is "NSD-G1000T".This ONU also functions as a hub for IoT home appliances such as smart locks, smart home appliance remote controls, and communication cameras prepared by NURO. In addition to Wi-Fi 6, it is equipped with one 2.5GBASE-T port and three 1000BASE-T ports. ..NURO Hikari has the potential to use up the line speed of "maximum downlink 2 Gbps / maximum uplink 1 Gbps" with one handset (although it depends on the environment and congestion, of course).■ Pay attention to Sony ONU that can be used in "NURO Smart Life" ■ Basic functions are firmly installed, 5GHz band supports 160MHz ■ "Wi-Fi 6 + 2.5GBASE-T" makes the Internet fast!■ Utilizing 2.5GbE, which is faster and cheaper, of course, in the LAN ■ Enhanced home security!Further benefits of "NURO Smart Life" ■ Wi-Fi setting with QR code and family return notification function!"NURO Hikari" App ■ Check it out if you want to make the most of NURO Hikari's "downstream maximum 2Gbps"!The rental equipment provided is ONU (optical network unit) with a built-in Wi-Fi router function. The network is 1000BASE-T with a maximum of 1 Gbps for wired LAN, and Wi-Fi with a maximum of 1300 Mbps. The spec is Fi 5 (IEEE 802.11ac).Basically, it is a service that provides "smart life" as mentioned above, but by subscribing to this option, the provided ONU will be changed to Sony's "NSD-G1000T".In addition to providing the core functions of "smart life," this ONU has been enhanced with network functions such as 2.5GBASE-T.By the way, this "NURO Smart Life" was an option that could be selected only when the line was introduced, but now it is possible to make an option contract even after the introduction.In other words, by subscribing to NURO Smart Life and exchanging ONU for NSD-G1000T, the practical limiter of NURO Hikari will be canceled, and a connection method that uses up 2 Gbps with one unit will be provided.You can log in to the setting screen according to the attached guide, but basically, it has all the functions that a general Wi-Fi router has.In addition to the DHCP server and port mapping, it is also equipped with a firewall function that responds to attacks such as band steering that automatically divides the 2.4 GHz band and 5 GHz band of Wi-Fi, and DoS.In addition, the band of 5GHz band can be selected from 20MHz / 40MHz / 80MHz / 160MHz, and it was set to 80MHz by default.If you have a Wi-Fi 6 compatible handset that can communicate at a maximum of 2402 Mbps, such as a notebook PC, you should change it to 160 MHz.However, it is necessary to set the Wi-Fi connection ID and password separately.You need to either reset the Wi-Fi settings of the handset according to the connection guide attached to the ONU, or change the Wi-Fi router function settings to the same SSID and password as before.The "HG8045Q", which is a 1000BASE-T connection, records a maximum of 950Mbps.In addition to that, the value of around 800 Mbps has come out, and it can be seen that the communication speed close to the limit of 1 Gbps can be secured.Then, when I tried it with "NSD-G1000T" connected by 2.5GBASE-T, Google and FAST.com recorded about 2Gbps.It was confirmed that the 2 Gbps, which is the limit speed of the line, can be fully utilized.Some of them, such as Radish Network Speed ​​Testing, do not exceed 1 Gbps, but these probably have a measurement limit of 1 Gbps on the website side.Also, the reason why it exceeded 2000 Mbps even though it was a 2 Gbps line is probably due to the measurement error and the numbers such as 1 Gbps = 1024 Mbps.When measuring over the Internet, speed reduction may occur due to factors other than ONU and line.Therefore, I was worried whether the speed would be 1 Gbps or higher in the actual measurement, but in reality, I was able to confirm the speed close to the limit of 2 Gbps.Not only the performance of ONU, but also the goodness of the NURO Hikari line itself was confirmed.With the "HG8045Q," which has a maximum of 866 Mbps on Wi-Fi 5, it was about 350 to 580 Mbps.The communication speed of the Wi-Fi connection is usually a few percent below the standard limit, which is a reasonable number.The "NSD-G1000T" will connect with Wi-Fi 6 at a maximum of 2402 Mbps.In addition to recording 1.2 Gbps on FAST.com, we were able to confirm a speed of over 1 Gbps on Google.Both tests confirmed almost twice the speed, clearly showing the benefits of Wi-Fi 6 speedup.Also, when I measured it with a smartphone that supports up to 2402 Mbps with Wi-Fi 6, I was able to confirm a value exceeding 1 Gbps on FAST.com.Although the speed varied from trial to trial, if the Wi-Fi environment and Internet line conditions are favorable, even Wi-Fi can actually exceed 1 Gbps.Even with Wi-Fi, speeds exceeding 1 Gbps can be achieved, and if there is a device that supports Wi-Fi 6, it can be said that the ONU side also has a great advantage in making it compatible with Wi-Fi 6.There is a way to add a Wi-Fi 6 compatible router (access point) without replacing the ONU, but in this case, the wired port of the old ONU will be up to 1 Gbps, which can be a bottleneck.If you want the best Wi-Fi environment, it can be said that the introduction value of "NSD-G1000T" is worth it.I also tested it in the LAN to see the performance of the NSD-G1000T as a Wi-Fi router.First, I compared the speed of HG8045Q and Wi-Fi.The slave PC supports a bandwidth of 160MHz, and the maximum link speed is 2402Mbps.The communication partner is a PC connected by wire with 2.5GBASE-T (in "HG8045Q", it is connected with 1000BASE-T).In addition to short-distance communication in the same room, in the 3LDK condominium that is the author's house, this unit is placed in the room on the aisle side, the PC is placed at the end of the room on the veranda side, and the three wooden doors in between are closed. I communicated with.* The unit is Mbps.iPerf3 is executed 10 times with the parameter "-i1 -t10 -P10" and the average value is posted.However, looking closely at the verification data, the HG8045Q had a timing when the communication speed became 0 intermittently, but the NSD-G1000T was able to communicate almost constantly.It seems that there is not much difference in the range of radio waves, but the NSD-G1000T seems to be better in terms of communication stability.As another test in the LAN, I connected the 2.5GBASE-T compatible Buffalo NAS "LinkStation LS710D0201" directly to the old and new ONUs and checked the read / write speed from a notebook PC connected via Wi-Fi.With the combination of Wi-Fi 5 and 1000BASE-T, it was about 57MB / s for sequential read and about 87.3MB / s for sequential write, while with NSD-G1000T connected with Wi-Fi 6 and 2.5GBASE-T, The former was about 72.6MB / s and the latter was about 106.8MB / s, improving by about 20% each.If you want to connect a PC with a 2.5GBASE-T wired LAN in addition to the NAS in this environment, it is recommended to connect a 2.5GBASE-T compatible switching hub to the NSD-G1000T and connect the PC or NA to it. is.If you are using the NSD-G1000T and have multiple 2.5GBASE-T compatible devices, you should consider introducing it.Some 2.5GBASE-T compatible switching hubs sell for less than 10,000 yen, and the NAS tested this time can also be purchased for around 17,000 yen.First is support for IoT devices.For example, the smart lock "Qrio Lock" that allows you to easily unlock the house key with a smartphone or remote control key usually requires a core device called "Qrio Hub", but the NSD-G1000T has a built-in Qrio Hub function. ing.There is no need to prepare equipment separately, and you can save money (9,680 yen for the "Qrio Hub" alone).The NSD-G1000T also supports control of indoor communication cameras and smart home appliance remote controls.The "NURO Hikari" app, which is provided free of charge to NURO Hikari members, is also quite convenient.In addition to being able to easily check usage charges and access My Page on a smartphone, it also has a function that allows you to connect to ONU's Wi-Fi simply by scanning the QR code affixed to the ONU.The improvement of communication speed by supporting 2.5GBASE-T is also wonderful.Even if the maximum downlink speed is 2 Gbps, NURO Hikari is a best-effort service, so I thought it would be enough if it was close to 1 Gbps ... but in reality, I could literally confirm the communication speed of 2 Gbps. rice field.I realized that I hadn't used up my line speed so far, and I felt it was a waste.To benefit from the increased speed, communication devices must also support the latest standards such as 2.5GBASE-T and Wi-Fi 6.Recently, 2.5GBASE-T related devices have become cheaper, and the number of PCs and smartphones that support Wi-Fi 6 is increasing.It can be said that it is a good time from an environmental point of view to take the communication standard to the next step.You can choose Sony ONU, and the communication speed will increase substantially, and you can use IoT devices and receive SECOM services.If you are using a course with a maximum downlink speed of 2 Gbps for NURO Hikari, or if you would like to introduce it in the future, don't forget to check NURO Smart Life.Copyright © 2018 Impress Corporation.
