ZTE U10S Pro 4G portable wifi body is small, flat and easy to carry, the front of the fuselage has a concave and convex texture design, the right side is printed with the ZTE brand, and the left side is equipped with a round smart display.
The display has multiple functional interfaces, such as interface 1, which can display information such as date, battery level, signal, service area status, etc.
On page 2, you can display information about the used traffic.
Interface 3 can display the upload and ** network speed in real time.
The ZTE brand is printed in the center of the other side of the fuselage.
One side of the fuselage is equipped with an on/off button and a function key for switching interfaces.
On the other side, it is equipped with the mainstream USB-C charging interface, which has a wide range of adaptability and can reduce the number of external cables for users.
There is an inner groove at one end for the user to open and replace the battery.
The size of the product in the hand is intuitively felt.
In addition, the net weight was measured to be about 119g.
To charge the ZTE U10S Pro 4G portable WiFi simply, the input power measured with the ChargerLab Power-Z KM003C is about 661w。
After reading the unboxing and display of ZTE's portable wifi, let's disassemble it and take a look at the internal scheme and design.
First, remove the back cover that is secured by the snap.
Information labels are pasted inside the fuselage, and wireless antennas are provided on both sides.
The antenna on the side of the fuselage is labeled A1.
The antenna on the other side is labeled A2.

Unscrew the set screws and remove the back cover.
There are antenna contact points on both sides of the back cover.
The shell is made of PC+ABS material.
There is a PCBA module inside the housing.
Take out the PCBA module, and inside the housing is the LCD screen.
The metal casing of the screen is pasted with metal foam on the back.
A glance at the back of the PCBA module, equipped with a battery connector, SIM card slot, two SMD buttons in the upper left corner, a reset button in the lower left corner, a USB-C female socket at the bottom, and a large-area shielding cover on the right side.
There is a shielding cover on the right side of the front of the PCBA module, and a large area of copper and gold is exposed in the PCB to strengthen heat dissipation.
Disassemble and remove the shield on the back of the motherboard.
A glance at the internal circuitry of the shield, soldering baseband processor and memory, RF transceiver chip, wifi chip.
The baseband processor is from ZXIC ZTE Microelectronics, model ZX297520V3, which is a baseband processor that supports five network modes such as TD-LTE and FDD-LTE, using 28nm process, suitable for mobile terminals and other devices, with the advantages of low power consumption, high cost performance and high integration.
The memory comes from Longsys, model F35UQA001G, which is SLC NAND, with a capacity of 128MB and an SPI interface.
The RF transceiver chip also comes from ZXIC ZTE Microelectronics, model ZX234230A.
The WiFi chip is from AGCO, model AIC8800DW, which supports WiFi6 wireless network.
