These functions enable the Cellular Router to provide a secure and stable network environment for the devices connected to it.
Cellular Modem: Its routing management and security functions are relatively weak. Since it mainly focuses on data transmission, it usually only provides basic network connection parameter settings, such as APN (Access Point Name) settings. In terms of security, it mainly relies on the security mechanisms of the device itself and the security guarantees of the cellular network, lacking the rich security configuration options of a Cellular Router.
Cellular Router: It generally has a relatively rich set of interfaces and expansion functions. In addition to Ethernet ports and Wi-Fi functionality, some Cellular Routers are also equipped with USB interfaces, serial ports, etc., allowing the connection of external storage devices, printers, sensors, and other devices for further functional expansion. For example, by connecting a USB storage device, the router can be turned into a simple network storage server, facilitating file sharing among users.
Cellular Modem: It has a high degree of device integration and usually only provides the necessary data interfaces for connecting target devices. Its extensibility is relatively limited and is mainly optimized around data transmission functions. However, some high-end Cellular Modems also support software upgrades to add new functions and features to adapt to changing application requirements.
In home and small office environments, multiple devices usually need to access the Internet simultaneously, such as computers, mobile phones, tablets, and smart TVs. In this case, a Cellular Router is a more suitable choice. It can provide a unified network access point for these devices, facilitating network management and configuration for users. For example, users can set different wireless network names and passwords through the Cellular Router to isolate the home network from the office network, improving network security. Additionally, the Wi-Fi coverage function of the Cellular Router can meet the wireless connection needs of devices within the home and small office areas, eliminating the need for additional network cable layout and saving on wiring costs and space.
In the field of industrial automation, a large number of industrial equipment and sensors need to transmit data to a monitoring center in real-time to enable remote monitoring and control of the production process. Cellular Modems have obvious advantages in such scenarios. Due to their compact size and easy installation, they can be directly integrated into industrial equipment without the need for additional network device support. For example, in the petrochemical industry, temperature sensors and pressure sensors distributed in various production links can transmit data to the monitoring center in real-time through Cellular Modems, allowing staff to monitor the operating status of production equipment at any time and promptly identify and address potential problems. Moreover, the low power consumption characteristics of Cellular Modems make them suitable for use in industrial scenarios with high energy consumption requirements.
For users who often need to work outdoors or in mobile environments, such as business people, journalists, and surveyors, a device that can provide network connections anytime and anywhere is required. Cellular Routers can meet this demand. Some portable Cellular Routers are small and lightweight, making them easy to carry. They also support multiple power input methods, such as battery power and vehicle charging, making them suitable for outdoor use. Users can connect the Cellular Router to laptops, tablets, and other devices and share the network via Wi-Fi, enabling multiple devices to access the Internet simultaneously. Additionally, the security functions of Cellular Routers can also ensure the data security of users when using the network outdoors.
In the fields of intelligent transportation and the Internet of Vehicles, vehicles need to communicate real-time data with transportation infrastructure, other vehicles, and cloud platforms. Both Cellular Modems and Cellular Routers have certain application spaces. For simple vehicle monitoring devices, such as on-board GPS locators, Cellular Modems are usually used to transmit vehicle location information, driving speed, and other data to the monitoring center. For more complex intelligent connected vehicles, Cellular Routers may be required to achieve network connections for multiple devices inside the vehicle (such as on-board entertainment systems and intelligent driving assistance systems) and enable data interaction with the outside world through the cellular network.
Generally speaking, the equipment procurement cost of Cellular Modems is relatively low. Due to their relatively simple functions and structures, their prices are usually lower than those of Cellular Routers. Cellular Routers, on the other hand, require higher hardware configurations and software support because of their more functions and interfaces, resulting in relatively higher prices. However, specific prices are also affected by factors such as brand, model, and performance. For example, USR's Cellular Modems and Cellular Routers have different price ranges in the market, and users can choose according to their budgets.
