The advantages of multiple network cards

Network optimization

Built in multiple carrier networks, automatically selecting the optimal network for the current device location,Complete automatic switching in 20 seconds,Improving device connectivity is more effective for government departments to regulate and prevent data interruption or loss.

Convenient and easy-to-use

It comes in various forms, including SIM card size, 5 * 6DFN packaging patch size, and can also be customized specifically. IoT users can directly insert or solder it to IoT and other terminal devices that need to be connected to the Internet, with low installation threshold and simple and easy to use.

Reduce costs

No need to conduct on-site surveys of network signals in advance to determine which operator's cards to purchase, no need to modify hardware design, and adapt to all solutions; One package, connecting multiple carrier networks at no additional cost.

Network Disaster Recovery

Currently, in the event of a network failure, switching to a backup network is supported to increase device online time.

Network fluctuations, automatic switching, no need for interference, truly achieving 24/7 connectivity online.

Application scenarios

Robot

Provide networking services for service robots, humanoid robots, delivery robots, cleaning robots, drones, and more.

Share economy

Shared vending machines, shared bicycles, shared cars, shared massage chairs, shared power banks, etc.

Smart city

Smart parking, smart agriculture, smart meter reading (for water, electricity, and coal), smart streetlights, smart greenhouses, data collection, etc.

Terminal equipment

Portable WiFi, CPE, smart blood pressure monitor, POS machine, translator, smartwatch, etc.

Security field

Intelligent security solutions such as access control monitoring, highway monitoring systems, and scenic area cameras.

Internet of Vehicles

Car WiFi, car locator< span style="color:#666666;font-size:12px;text-wrap-mode:wrap;background-color:#FFFFFF;"> Driving recorder, rearview mirror equipment, onboard diagnostic system, etc.

Comparison of IoT Network Card Types

Comparison of Differences between Multi Network Card and Single Network Card Products

Comparing dimensions	Multi network card	Single network card
Real time networking rate of IoT devices	High (you can choose the network with the best network signal for networking)	Low (IoT devices have different network signals from different operators during their movement, which affects the Real time networking rate of devices
Network Disaster Recovery	Yes (once the current network fails, it can automatically switch to another network, Equipped with network backup to ensure real-time online connectivity of IoT devices	None (Once a network failure occurs, it will cause significant losses)
The cost of equipment maintenance	Low (no need to survey network signals in advance, automatically select the optimal network connection)	High maintenance costs (when installing IoT devices, it is necessary to survey network signals in advance, which requires high labor costs)
User Experience	good	general
