Draft 11ac compatible Next Generation High Speed ​​Wireless LAN Router "Aterm WG 1800 HP" has measured how much speed actually comes out

It is a next-generation wireless LAN standard capable of super high-speed communicationIEEE802.11acWireless LAN router corresponding to "Aterm WG 1800 HP"is. Since the wireless LAN router currently being used slightly dissatisfied with the communication range and range within which the speed & radio can reach, we actually purchased it to see how we can improve this new standard called 11ac I tried using it variously.

This is the Aterm WG 1800 HP and the slave unit for receiving 11ac's wireless LAN "Aterm WL 900 U".


Opened Aterm WG 1800 HP immediately.


This is the main body and the main body support.


When you attach support, it looks like this.


It is also possible to make it vertical.


There are six status indicator lamps on the main unit, ECO button, and easy start button are attached.


On the side of the main unit are a switch for switching the main unit to the main unit or the slave unit, in order from left to right, one AC adapter port, one WAN port, four LAN ports and one USB 2.0 port.


Since the back side has considerable heat, I measured the surface temperature and it was 46.4 degrees even though I did not communicate. Apparently, it seems that the parts where heat is generated are concentrated on this back part, so it seems that it is designed so that heat does not stay by direct contact with the top of the desk etc. floating here when laying it sideways. So, you need to be careful about the installation location.


Next, remove AtermWL 900U from the box.


This handset is like this.


Taking the lid has a USB plug.


It is like this when inserted in a personal computer. It is saved if the lid is attached to the part of the but it is impossible, so management is essential so as not to lose the lid.


◆ Measurement test procedure

The data rate measured this time via wireless LAN. Since this is not a broadband connection, it should be able to ascertain high-speed transfer performance of 11ac without being influenced by the speed of the internet line. So LAN cable is not inserted in Aterm WG 1800 HP.


In order to see how fast 11ac can communicate at high speed, we also measure how much transmission speed comes out with communication standards other than 11ac.

Since there was no way to limit the communication to ac only on the router side, I called the support and confirmed it that I could do it by changing the handset side in the following procedure. First, click "Hardware and Sound" from Windows 7 "Control Panel".


Click "Device Manager" ... ....


Right-click "NEC AtermWL 900U" in "Network adapter" and click "Properties".


You can use 11ac using the 5GHz band by clicking "Advanced settings" from the menu of the property and selecting "IEEE 802.11a / n / ac" from the value of "Wireless Mode". Answer from support that if you can communicate this setting will probably use ac. Although it is impossible at this moment to strictly use only ac, in theory it seems that if you are using the speed, you are using ac.


Compared to 11ac is the 2.4 GHz band11 g and 11 bWith a maximum transmission speed of 54 Mbps and 11 Mbps, respectively.


Software to measure in the pastI measured the speed of the LAN cableWhen used "LAN Speed ​​Test v3.4.0". This software can eliminate the influence of the cache function owned by the system of Windows itself, so real transfer without any difference in transmission speed due to caching that occurs when transferring by simple file read / write It can measure the speed. I confirmed that it is possible to measure not only the wired LAN but also the speed of the wireless LAN without problems.


As a measurement rule, insert AtermWL 900U into the USB 3.0 port of two PCs, stop all the radio functions of the main body, and let the personal computer read and write data via Aterm WG 1800 HP. Measure the speed seven times, and record the results of Writing (Upload) and Reading (Download), matching the two communication standards to 11 a / n / ac. Next, the transmission speed was measured in the same way according to the communication standard 11b / g. Also, in order to verify the range of Aterm WG 1800 HP radio waves, Aterm WG 1800 HP was set up on the 3rd floor of the building, and the 1st, 2nd, 3rd, 4th floors of the same building, the 2nd floor of the adjacent building and Move the 3 rd floor and 2 PCs and measure the transmission speed at each place. It stops all resident software such as antivirus software which affect speed, so that communication and filtering other than measurement are not applied at all. Furthermore, in order to suppress extreme errors and averaging, the maximum value and the minimum value for each measurement are excluded, and the average value for each point is calculated with the remaining value.

In short, the following conditions are set.

4 th floor: How far will it reach in the upward direction on the floor just above the soundproofing material?
3rd Floor: Assuming places where you can see in the same room on the same floor, ordinary apartment or your own room
2nd Floor: How far will it reach down the floor directly under the steel frame?
1st Floor: How much more will you reach with the most severe conditions even one more step over the steel frame, down to 2 floors?
3rd floor of the adjacent building: How far can you penetrate the concrete wall in the sideways direction?
2nd floor of the adjacent building: How far can you penetrate the concrete wall in the diagonally downward direction?

The measurement result is like this. On the same floor, it is still considerably faster, but it is still pretty severe through the steel frame. Also, we found that weak in the vertical direction, but considerably strong in the horizontal direction.

◆ Upload: 2.4 GHz (b / g) → 5 GHz (a / n / ac)
1st floor: unmeasurable (no connection at all) → unmeasurable (can not connect at all)
2nd floor: 2.79 Mbps → 1.04 Mbps
3rd Floor: 8.76 Mbps → 70.09 Mbps
4th Floor: 8.39 Mbps → 17.11 Mbps
Second floor of separate building: 9.61 Mbps → 42.33 Mbps
Floor 3F: 9.22 Mbps → 33.30 Mbps

◆ Download: 2.4 GHz (b / g) → 5 GHz (a / n / ac)
1st floor: unmeasurable (no connection at all) → unmeasurable (can not connect at all)
2nd floor: 2.40 Mbps → 0.63 Mbps
3rd Floor: 8.67 Mbps → 77.04 Mbps
4th Floor: 5.68 Mbps → 33.76 Mbps
Separate building 2F: 9.49 Mbps → 49.60 Mbps
Floor 3F: 9.34 Mbps → 29.26 Mbps

In order to make the above figures easy to understand, it becomes as follows as a graph.

In conclusion, as a matter of course, it is commonplace to say that it is natural, but the value of "1300 Mbps" in the package of Aterm WG 1800 HP used as the parent machine or "Draft 11ac compatible with 867 Mbps" written in the description of AtermWL 900 U used as a slave Is only the theoretical maximum, even if it is on the same floor where you can not see it, such speed will not come out as actual measurement results. Although it can not be confirmed in a strict sense whether it really can communicate with ac, the speed surely increases up. It seems to be worth replacing when the wireless LAN router at hand only supports g degree.


According to price.com, the parent machine at the time of article writing "Aterm WG 1800 HP"The lowest price is 14,996 yen, the slave unit"Aterm WL 900 U"Is the lowest price of 7772 yen. Also, we will purchase another company's ac compatible wireless LAN router and will be tested, so please do not hesitate to contact us.
