华硕AC86U与H3C BX54

ASUS AC86U, in 802.11ac products (Wi-Fi 5), 5G is very strong, no objection, right?

Currently inside Wi-Fi 6 products, Qualcomm’s strongest wireless chip is QCN9074, which is installed inside the H3C BX54, and the Asus AC86U is comparable in price. This is a comparison of 5G signal performance only, and in 802.11ac (Wi-Fi 5) mode. 5G of the BX54 should be set to 802.11 a n ac, without ax.

H3C 设置01

Both channel settings 44, bandwidth using 80MHz, AC86U updated to the latest firmware: 3.0.0.4.386_41634, region setting: USA.

Second, the hardware parameters (installed professional)

First, let you understand the two wireless routers 5G chip configuration: (the following material are their own disassembly pictures, BCM4366E is to tear through the AC88U in, SKY857433-11 is the Tengda MW6 disassembly)

QCN9074

The 5G chip of H3C BX54 is QCN9074 and the FEM chip model is SKY85747-11.

The 5G chip of ASUS AC86U is BCM4366E, and the FEM chip model is SKY85743-11.

The package size of both FEM chips is 24-pin, 3 x 5 mm, which is also the largest size at present, with the advantage that it can be stuffed into a larger PA die.

The two are compared under 802.11ac, 80MHz, 256-QAM, so just look at the corresponding amplification power parameters of this one.

SKY85747-11: MCS8/9, VHT20-VHT80, -35 dB DEVM +23 dBm

SKY85743-11: +24 dBm, -35 dB DEVM, MCS9

Both LNA receive gain is 16 dB

It seems that in Wi-Fi 5 mode, the ASUS AC68U amplifier is stronger than the H3C BX54.

Three, in Wi-Fi 5 wireless signal strength test comparison

The two wireless routers were placed in the “WIFI” position in the figure below, and the computer with AX200 wireless card was placed in four different positions in the figure below to record the wireless signal such as the rate, and the recording time for each position was three minutes. The two routers are individually placed in the same location for testing, not placed together at the same time to test to avoid mutual interference with the signal.

Although not to 2.4G speed measurement, but the signal is still measured together, 2.4G channel are 9, 802.11n mode.

The test results are as follows.

A点

The BS54’s 2.4G signal is stronger than the AC86U’s in the point A position separated by a wall; the 5G signal I think is stronger in the AC86U, which can be compared from the wave crest.

B点

In the location of the B point separated by two walls, so messy ah! 5G signal matters both landing more, 2.4G is still BX54 strong some; BX54 2.4G strong some.

In the straight line distance of 11 meters away from the location of point C, 2.4G is still BX54 strong; 5G signal strength difference is also not obvious, BX54 strong so a little.华硕AC86U与H3C BX54

Finally, when I came to the first floor of the D point location, the 2.4G signal strength is still better than the BX54 performance, and then the 5G signal is a little stronger than the AC86U.

Fourth, the 5G speed comparison in Wi-Fi 5 mode

Next is the 5G speed test, the test receiving terminals are Xiaomi 10, Apple SE2, Huawei Mate20, AX200, these terminals in close proximity to the two wireless routers 5G rate is 866Mbps (router are Wi-Fi 5 mode).

As with the previous wireless signal strength test locations, each location was measured 6 times in a row, and the final average was taken for comparison.

Each device is connected schematically as follows.

1、Speed comparison with AX200

All the results are shown in the following table.

AX200 01

The 5G speed measurement average is shown below.

AX200 02

In addition to the downstairs D point location of the uplink speed AC86U a little faster, the other are BX54 to be faster.

2, using Xiaomi 10 cell phone speed measurement comparison

All the results are as follows.

The 5G speed averages are as follows.华硕AC86U与H3C BX54

How can the BX54’s speed measurement exceed 750Mbps at the close location of point A? But the AC86U also supports 1024-QAM, and I see the client connection rate in the background of the BX54, it shows 866Mbps.

So here the Xiaomi 10 test results nullified, can not be used as wifi5 mode speed measurement comparison. Because it is not fair!

3, with Apple SE2 phone speed test comparison

All the results are as follows table.

华硕AC86U与H3C BX54

The average speed of 5G is as follows.

The Apple SE2 does not have the speed irregularities of the Xiaomi 10.

BX54’s downlink speed performance is better, but the uplink speed is AC86U fast.

4, using Huawei Mate20 phone speed measurement comparison

(The phone is supporting 160 bandwidth, but the BX54 is set up with a fixed 80MHz bandwidth)

All the results are listed below.

华硕AC86U与H3C BX54

The 5G averages are compared as follows.

华硕AC86U与H3C BX54

The 5G downlink speed BX54 is not all the way flat either, being overtaken by AC86U at the C point position.

From the speed measurement results of these previous receiving terminals, there is no phenomenon of one side completely crushing the other. If we have to draw a conclusion, it can only be that the downlink rate of BX54 is higher than AC86U, and the uplink speed is higher than AC86U.

Asus AC86U antenna height is inherently favorable, if the BX54 is padded to the top of the AC86U antenna horizontal position, the result may be the BX54 all win, but who would be so bored to pad a wireless router to use ah. It doesn’t make sense!

Finally, test the BX54 in Wi-Fi 6 mode with Xiaomi 11 to measure the speed and how much improvement there is compared to AC86U. Because the BX54 only has a gigabit port, the bottleneck is limited to 1Gbps in close proximity, so close proximity does not respond to the maximum speed. Let’s see if it will win all.

V. 5G speed comparison in Wi-Fi 6 mode

Xiaomi 11 supports 160MHz and 4096-QAM, which is a very good match for BX54. (Same with Xiaomi AX6000 and Xiaomi AX9000)

This is an unfair test comparison, I hope it will not cause misunderstanding, so then the following chart I will use a different color than the previous, as a reminder.

All 5G speed measurement results are as follows table.

华硕AC86U与H3C BX54

The 5G averages are compared as follows.华硕AC86U与H3C BX54

Thanks to the 160Hz bandwidth and 4096-QAM, the Xiaomi 11’s 5G speed is substantially thrown off the AC86U with only 80MHz bandwidth. as the distance increases, such as at points C and D, the BX54’s uplink speed doesn’t take much advantage.

At the point C location, the BX54 allows the Xiaomi 11 to reach speeds of over 800 MHz as well, which is pretty good.

VI. Summary

BX54 that even in Wi-Fi 5 mode can reach the 5G performance of AC86U, and in most cases, the 5G downlink speed is a little higher than AC86U, the downside is that the BX54’s uplink speed is not outstanding enough. The result is also in line with my expectations, after all, AC86U is not weak in the first place.

Some people say 160MHz bandwidth is not practical, far more attenuation, then see the above Xiaomi 11 actual test, long-distance under the misconduct is obvious QAM, each level of QAM caused by the rate difference of 20%, QAM pole number and EVM, far away, EVM high, QAM can only be adjusted downward, but will not affect the 160MHz.

Currently using wifi5 routing, it is necessary to switch to wifi6? It depends on your pursuit of speed and how many megabytes of broadband you are using, if it is about 100 megabytes, near and far will not show the difference in speed.
