What is 4G module
4G module said TD-LTE and FDD-LTE and other LTE network standards are collectively referred to. It has the characteristics of fast communication speed, wide network spectrum and flexible communication. 4G module refers to a product whose hardware is loaded to the specified frequency band, software supports the standard LTE protocol, and software and hardware are highly integrated and modular. The hardware integrates radio frequency and baseband on a small PCB board to complete wireless receiving, transmitting and baseband signal processing functions. The software supports voice dialing, SMS sending and receiving, dial-up networking and other functions.
Second, how to use 4G module
The 4G module is usually inserted into the circuit board or the patch module is welded to the circuit board, and the corresponding SIM card is inserted, and the network is connected through the 4G cellular network. In the common transparent transmission mode, data can be directly sent to the target server through the 4G module, and the 4G module can receive data from the server at the same time, and send the data to the serial port, which is received by the serial port device connected to the 4G module. Users do not need to pay special attention to the data conversion process between serial port data and network data packets, only need to insert the module to the target position, simple connection and parameter setting, you can achieve transparent transmission between the serial port and the network end.
What is the 4G module How does the 4G module work
4G module, also known as 4G transmission module, 4G communication module, 4G LTE module. It is a kind of hardware loaded to the specified frequency band, the software supports the standard LTE protocol, and the software and hardware are highly integrated modular products, with good compatibility, fast communication speed, large amount of communication data, wide network spectrum, communication flexibility and other characteristics, widely used in electric power, environmental protection, finance, industrial automation and other fields.
The working principle of 4G module
It has the characteristics of fast communication speed, wide network spectrum and flexible communication. The hardware integrates radio frequency and baseband on a small PCB board to complete wireless receiving, transmitting and baseband signal processing functions. The software supports voice dialing, SMS sending and receiving, dial-up networking and other functions.
Through high-speed networking, the 4G module transmits all terminal business data and equipment operating status to the business center in real time. Through the management monitoring platform, the terminal equipment operating status can be monitored in real time and equipment faults can be timely checked. The efficiency has been greatly improved in many aspects such as operating cost, operation scale and service timeliness. Suitable for shared massage chair, public charging pile, vending machine, vehicle system, environmental monitoring, power remote monitoring and other industries.

Good compatibility
4G module supports FDD LTE/TD-LTE two LTE standards, can also be backward compatible with 2G/3G, support LTE-FDD, LET-TDD, WCDMA, TD-SCDMA, CDMA, GSM and other bands.
Large amount of communication data
4G module downstream rate can reach up to 150Mbps, uplink rate can reach up to 50Mbps, to provide customers with high-speed Internet access and wireless data connection and other functions, suitable for large data transmission applications, such as: remote video surveillance.
High communication speed
The 4G module has a lower ping value than the 2G/3G module, and it takes less time for the module to send data packets to receive the response from the server, which is suitable for applications requiring high response speed, such as remote alarm.
BenQ has once again made a significant move in the home theater market by launching the W1700, the Light 4K Star Series projector, on December 11th. This model follows the successful release of the W11000 and X12000 4K DLP projectors last year. The W1700 is a breakthrough product that uses a 0.47-inch DMD chip and DLP technology to deliver 8.3 million pixels of true 4K Ultra HD resolution. Despite its compact size—only a quarter of the size of commercial 4K projectors—it brings high-end performance to a more affordable price point, making it accessible to a broader audience. By combining cutting-edge technology with a sleek, stylish design, BenQ aims to bring 4K home theater experiences into everyday living rooms.
The W1700 is not just about size and price; it’s about delivering an immersive and cinematic experience. With a lightweight build (only 4.2kg), it's easy to install and place anywhere in your home. Despite its small form factor, it can project images over 100 inches, ensuring every detail is visible with stunning clarity. Whether you're watching a movie or playing a game, the W1700 delivers sharp, vivid visuals that bring content to life.
In terms of image quality, the W1700 leverages HDR10 technology to enhance contrast and color depth, providing a more dynamic and lifelike viewing experience. It also features an advanced RGBRGB color wheel that ensures accurate color reproduction, covering over 96% of the Rec.709 color gamut. Combined with CinematicColor and CinemaMaster Video+ technologies, the W1700 meets industry standards for color accuracy, making it ideal for film enthusiasts who demand the best.
The optical lens system is another standout feature. Comprised of four groups of seven high-quality glass lenses—including two aspherical and five ultra-low dispersion lenses—the W1700 ensures sharp, clear images with minimal distortion. These lenses are designed to maintain image quality over time, unlike plastic alternatives that may degrade with use.
Audio is just as important as video when it comes to creating a true home theater atmosphere. The W1700 includes CinemaMaster Audio+ 2, which enhances sound quality through professional tuning and digital filtering. The built-in 5W stereo speakers offer rich, detailed audio, while five preset sound modes (cinema, games, music, sports, and custom) allow users to tailor the listening experience to their preferences.
Energy efficiency is also a key consideration. The SmartEco technology adjusts brightness based on the content being displayed, improving contrast and dark areas while extending the lamp life up to 15,000 hours. This not only saves energy but also reduces long-term maintenance costs, making the W1700 a smart investment for any home theater enthusiast.
Additional features like a 1.2X zoom lens and automatic keystone correction make setup quick and hassle-free. The projector’s compact size and lightweight design also make it highly portable, allowing users to move it between rooms or even take it on the go. Its dual infrared receivers ensure reliable remote control performance from multiple angles.
Overall, the BenQ W1700 is a game-changer in the 4K home theater market. It successfully combines advanced technology, portability, and affordability to bring premium 4K experiences to a wider audience. As consumer demand for high-quality entertainment continues to grow, the W1700 proves that 4K doesn't have to be reserved for professionals—it's now within reach for everyone.
