Frequently asked questions about Cellular Gateways
What is an industrial cellular gateway?
What is the difference between modems and gateways?
A modem is a combined device for modulation and demodulation of the digital data of a computer and the analogue signal of a phone line. Gateways are more complex, combining the functions of modems and routers.
What are the differences between Industrial Cellular and Industrial Wireless (Industrial WiFi) in industrial-grade mobile wireless communication networks?
Industrial-grade mobile wireless networks primarily utilize mobile communication networks, such as 4G or 5G, relying on mobile base stations for data transmission. These networks have broad coverage and are applied in various challenging environments, such as green energy, intelligent transportation, electric vehicle charging, public utilities, renewable energy, and safety and disaster prevention.
Industrial-grade WiFi adopts a point-to-point mesh network structure, known as Mesh, enabling each wireless access point (AP) to connect with others. Through network management software, the setup process for multiple Mesh APs is significantly simplified. This type of network is suitable for large area coverage and can improve signal distribution in corners. It is designed to withstand harsh industrial environments, capable of stable operation in temperatures ranging from -40°C to 70°C.
The main difference between Industrial Cellular and Industrial Wireless lies in the transmission distance. Additionally, Cellular transmissions rely on telecommunication carriers' base stations, while Wireless does not require this dependency.
What is NB-IoT?
NB-IoT (Narrowband Internet of Things) is a data transmission mode that offers a significant advantage over other Internet of Things (IoT) connectivity methods such as WiFi and LoRa. Its main advantage lies in not requiring WiFi setup. NB-IoT utilizes existing GSM frequencies and LTE technology to enable low-bandwidth signal transmission through telecommunication base stations, allowing devices to communicate instantly.
Unlike WiFi-dependent connections, where WiFi failures in the area or human actions like moving or renaming may cause devices to lose connection, other transmission modes might result in connectivity issues. However, NB-IoT continues to function asl long as the device is powered on, reducing connection issues.
What are the disadvantages of using WiFi wireless networks?
Wireless networks transmit signals through radio waves, allowing people with corresponding receiving devices to connect to the network as long as they are within the transmission range. However, because wireless network communication content is transmitted through open wireless channels, anyone with wireless devices can access the information, increasing the risk of eavesdropping. Additionally, if other people in the same building use wireless technologies or other sources of electromagnetic interference, it may lead to poor communication or signal interference. In comparison, wireless transmission speeds may be slower than wired networks.
Large-scale wireless networks typically use wired or fiber-optic connections as their backbone. Therefore, when designing wireless networks, it is essential to consider these potential issues and make appropriate plans to ensure the stability and performance of the wireless network.
