Preface
Using your phone to turn on your personal hotspot and share the network for your iPad, tablet or laptop is a common use case in your daily life. However, using a mobile phone to turn on a hotspot will increase the power consumption of the mobile phone, increase the heat generation and reduce the battery life, which will affect the use of the mobile phone. In response to this pain point, many manufacturers have launched mobile portable routers.
Inside, the mobile portable router features a simplified chip design that removes the massive application processor and retains the baseband and wireless connectivity for network connectivity and sharing. The following charging head network will bring a summary of the five mobile portable routers that have been disassembled, and see how the internal design is different.
HUAWEI
Huawei WiFi 3
Huawei's 4G WiFi 3 mobile router for mobile Internet. This product is flat and round, about the size of a bank card, and is very easy to carry. Support mobile/telecom/China Unicom 4G network card use, with such a device, you can play with your friends anytime and anywhere.
Huawei's on-the-go WiFi3 is small and has rounded corners, making it very portable and easy to use. Through the dismantling of the charging head network, it is learned that the product adopts a replaceable battery design, and the problem of battery aging after long-term use can be easily solved by the user himself. Further dismantling found that a thin-film antenna was used inside to save the volume of the product. In addition, HiSilicon baseband and PMIC are used to cooperate with TI battery management. There is a shield on the motherboard to ensure that the signals do not interfere with each other. Built-in SLC memory, long service life, stable and reliable.

Huawei 5G On-the-Go WiFi Pro
Huawei's 5G on-the-go WIFI Pro is equipped with an 8000mAh large-capacity battery, which can last up to 10 hours under high load conditions, supports 22.5W reverse wired charging and 15W reverse wireless charging, and comes with a Huawei 40W super fast charging charger. The product can convert 5G signals to high-speed WiFi through the Barong 5000 chip, realizing 5G dual-mode full Netcom, and non-5G mobile phones, tablets, laptops and other devices can also enjoy 10 times faster network speed than 4G. Without having to change your phone, this portable mobile router can take you to enjoy the 5G era, and can also be connected as a router to transfer large files with zero data.
Through the dismantling of the charging head network, it was learned that the machine is equipped with Huawei's HiSilicon Hi9500 Barong 5000 5G SOC core chip, and uses Hi6421/Hi6422/Hi6526 PMIC, Hi1151 wireless control chip, and Hi6365 RF transceiver. In addition, Hynix and Macronix memory chips, as well as Richtek's wireless charging solutions, are also used.
The chips on the sub-circuit board are all covered with metal shielding covers to avoid interference, and the main heating chips are also pasted with thermal pads to help conduct heat; the battery cells are placed in the grooves, and the groove area is made of aluminum alloy to help the cells dissipate heat; the wireless charging coil is tightly wound and the wire cores are soldered firmly. The overall workmanship of this product is excellent.

Wireless Cat Spirit
Wireless Cat Soul Portable WiFi
As a networking device between the wired network and the mobile phone network, portable WiFi solves the problem of using a mobile phone when going out, and the mobile phone uses 4G or 5G network to consume power quickly and heat up, becoming an important supplement to the wired network.
Through dismantling, the charging head network learned that this portable WiFi has a built-in Zhirong SW6106 mobile power SOC chip, which charges and discharges the built-in battery, and integrates switches and controllers inside the chip, with a high degree of integration and simplified peripheral circuits. The wireless module adopts ZTE's micro solution, and the overall solution has the advantages of low power consumption, high cost performance and high integration. The modular approach greatly simplifies product development and accelerates time to market.

Xinxun 4G wireless data terminal
Xinxun's 4G wireless data terminal has a built-in 8000mAh capacity battery, which ensures a good battery life without affecting its overall portability. In addition, it is equipped with a 1A1C interface, compatible with all mainstream 3 fast charging protocols on the market, supports 18W fast charging, and is convenient for rapid power storage and take-out use.
Through the dismantling of the charging head network, it is understood that the MIFI host has a built-in Zhirong SW6206 chip to achieve the basic charging and discharging functions, and the ultra-high integration is conducive to simplifying the circuit and reducing the size of the PCB board, and then compressing the size of the MIFI host, which is very important for such products that pay attention to portable take-out. In addition, Zhirong SW6206 can also provide rich interface configurations and fast charging protocols to enrich the functions of MIFI hosts. The MIFI module adopts a high-pass scheme and has stable communication.

ZTE
中兴5G随身WiFi6 Pro Max
The ZTE 5G portable WiFi6 Pro Max adopts a phone-like design, and the shell is coated with metallic paint, which has a delicate texture. There is a 2.4-inch touch screen on the front of the fuselage, with a resolution of 320*240, which is used for traffic display, signal strength, power display and other functions. This portable WiFi has a large built-in 10,000mAh battery that lasts up to 16 hours. It supports 27W fast charging and can be fully charged in 150 minutes. 18W reverse charging to meet the emergency charging of mobile phones.
Through the dismantling of the charging head network, it was learned that the internal design of ZTE's 5G portable WiFi is similar to that of a traditional mobile phone, with a battery inside the back cover and a wireless antenna on the edge of the battery. The internal Qualcomm X62 5G mobile platform chip, with two SDR735 RF transceivers and Qualcomm, QORVO and RADROCK power amplifier chips to achieve 5G network connection.
And use Qualcomm WCN6856 WiFi/BT chip for WiFi connection, the chip supports WiFi 6 standard, the maximum transmission rate reaches 3600Mbps, and supports 64 user connections. Use PM7250B with SMB1394 charging chip for PD fast charging and charge pump fast charging. According to different functions, the shielding cover is set up in the interior of the portable WiFi to ensure stable signal transmission without interference.

Summary of the charging head network
A mobile portable router is essentially a simplified version of a mobile phone, which uses indicators to display the status or use the screen to display simple information for users to understand the operating status and traffic usage information. By using a mobile portable router, you can free up your phone without affecting your phone's battery life, and it will not automatically turn off the hotspot, providing a stable and reliable network connection.
The mobile portable router launched in recent years not only provides network connection, but also has the function of fast charging mobile power supply. It has a built-in large-capacity battery, which not only provides long-lasting network sharing, but also has a fast charging output, which can quickly charge the mobile phone and add product use.
