What processor is Huawei b311b-853?

I just got this Huawei mobile router model B311B-853. The packaging date should be that it has just been launched. The product network access license and CMIIT ID are still XXXX, and the factory date is August 2020. The color is white, the product name is TD-LTE wireless data terminal, and the packaging is packaged in a white environmentally friendly carton. The BOM list includes: router, AC/DC power adapter, bracket, manual, and three-guarantee certificate.

The bottom of the product has a slot for inserting a Nano-SIM card and a thermal hole. This is more compatible than the Mirco-SIM of the previous Huawei 4G Router 2. After all, Nano-SIM has become the mainstream SIM specification of existing operators. And NanoSIM can be converted to MicroSIM or standard SIM size at will through the card holder.

According to the instructions provided by the manufacturer, this router supports the TD-LTE standard of China Mobile/China Unicom/Telecom, and can access the Internet wherever there is a signal.

Specific communication standard: Cat 4

Applicable network: 4G

4G transmission rate:

FDD LTE: DL 150 Mbps, UL 50 Mbps

TDD LTE: DL 110 Mbps, UL 10 Mbps

Next is the back of the fuselage, from left to right are the Reset holes, the inner positive and outer negative 12V DC The socket, four RJ45 network ports, and the label on the back of the fuselage indicate the product’s management address http://192.168.8.1 and the QR code for downloading the Huawei Smart Life APP.

There are two buttons on the top of the product, one is the Power switch and the other is the HiLink switch. Correspond to the router power startup and NFC connection functions respectively.

2. Product functions

According to the product introduction on Huawei's official website, this router supports four Internet access modes: 1. Mobile network to Wi-Fi; 2. Mobile network to wired; 3. Convert wired network to Wi-Fi; 4. Convert wired network to wired network. This has one more SIM card slot than ordinary routers and is used for multiple use of TD-LTE networks. Huawei has previously launched a product model with similar functions called B216-855. I used it on the Zaker platform in 2019. I also did a review in August. The difference is that this product performs a cost down operation on the 802.11 protocol, and the bandwidth is also reduced from 1176M in the 802.11ac specification to 300M in 802.11n. However, this 300M is enough for 4G to wired network. After all, the product positioning in this scenario is as an extension and expansion of TD-LTE network, and most applications can also meet the needs. Next, let’s take a look at the APP function of the product. Huawei has developed an APP called “Smart Life”. If your phone is a Huawei phone and supports the NFC function, you can directly achieve "one-touch connection" through the on-site communication function without entering a password.

On the wireless signal search page, the mobile phone will see an SSID with the Hi-Link logo. At this time, if you put the mobile phone close to the area with the Hilink logo on the front of the Huawei router, it will automatically connect, eliminating the need for Steps to enter the key.

After the router is powered on, the mobile phone with the APP installed will automatically scan for signals. After a while, the SSID signal of the router will be recognized and prompted to connect. The initial Wi-Fi password is empty. After connecting, you can enter the router's configuration page to set the Internet access method. After configuring the WAN port's Internet access mode DHCP\static IP\PPPoE dial-up, you can start using it.

There are two selling point functions on the APP worth mentioning here: 1. Channel optimization; this function is very practical. Nowadays, the signal interference of home Wifi mainly comes from nearby wireless devices. How to remove it? How to avoid interference from other signals under the same Channel? The solution provided by Huawei is channel optimization. This requires low-level support from the hardware technology of the device chip and cooperates with the APP for automatic adjustment.

Just click the [Optimize Interference] button on the WLAN Network Optimization (2.4G) page of the APP to automatically switch the Wi-Fi signal to a clean Channel, thus avoiding signal interference. interference situation.

Let’s take a look at the second selling point function: 2. Mobile game acceleration; this function is mainly a technology for the router CPU to encapsulate and optimize the passing network data packets. The router will detect the game data packets, thus Prioritizing sending serves the purpose of acceleration, which can be understood as algorithm acceleration. It is not channel acceleration based on network nodes like our NetEase UU and Raytheon NN. But the prerequisite is that it only supports Huawei EMUI9.0 or above systems.

Let’s take a look at the actual test results. Here I used the mainstream Tencent mobile online game "Peace Elite"

Test terminal: Huawei Mate20 Pro LYA-TL00 mobile customized machine

EMUI: 10.1.0

Android Version: 10

SIM card operator: China Mobile 4G TD-LTE

Test location: Wuhan, Hubei

Enable router mobile game acceleration Function: After a round of play, the game ping value is about 20ms, and the mobile phone’s acceleration record can be viewed on the mobile game acceleration page. The actual experience is not bad!

The next thing to explain is the dual-network and dual-pass function of the product. After inserting the SIM card and WAN port network cable, log in to 192.168.8.1 on the computer to see the current connection status. As shown below:

When the SIM card is inserted into the router, when dialing the mobile phone number, it will prompt that the line is busy. Here, the Huawei router provides a text message function on the web page. We can see the content of the text message received from 10086 in the toolbox-SMS-SMS session, and can edit the reply. This also has the same function in another Huawei 4G Router 2.

As the basic functions of wired routers, I also conduct functional tests, including support for DDNS dynamic domain names. The mainstream peanut shell Oray, DynDNS, and No-IP can all be logged in directly on the router.

Parental restrictions and Mac address black and white lists are also essential functions for many home routers, and Huawei mobile routers have not been neglected here. The corresponding settings page can be found in the toolbox.

Finally, I tested the product’s network signal coverage in a home environment. In a 100-square-meter 2-bedroom environment, the router is placed in the living room and can basically cover the entire room without any blind spots. Signal coverage (wifi signal strength is set to - wall penetration mode), this can be said to be quite satisfactory for home routers.
