Embedded 3G/4G Routers

Embedded 4G and 3G routers solve two problems that often plague traditional routers: cost and size, using boards that are tighter in footprint, yet massive in their capabilities.   Robustel’s R1511P embedded router is smaller than a traditional router and easily used for space-constrained applications and devices. This router provides high-speed wireless network bandwidth for devices through a wireless connection, ensuring a stable connection to the network. 

What is a Cellular Embedded 4G router?

A cellular embedded router uses cellular connection instead of traditional wired connection. This bypasses wired cabling, using a 4G LTE cellular connection to provide connectivity for your network. These routers look similar to a standard one, but don't need to stay in one physical place—allowing more freedom for router placement and network setup.  

Applications of Robustel’s 3G 4G Routers 

An embedded 3G 4G router takes up less room than a traditional router, making them ideal for applications that require a solution that doesn’t take up much space. Robustel’s routers can also be easily integrated into custom products and projects - suiting a range of industries, from smart cities to medical and retail applications. Equipped with two Ethernet ports, these routers communicate with measuring systems and support Modbus communication protocols.  Robustel’s R1511P LTE embedded router is designed for various space-constrained IoT applications such as:
  • EV charging
  • Traffic signs
  • Vending machines
  • Medical Instruments
  • Industrial instruments
  • Smart farming machinery
  • Energy and utility systems.

Benefits of an embedded 4G router 

Embedded 4G routers offer a range of benefits over their traditional counterparts that make them a highly desirable solution across a range of industries. These benefits include: 
  • Cost-efficient embedded routing. The R1511P offers a small footprint 4G/LTE Router board at a competitive price. 
  • Designed to Fit. The R1511P has a small yet simple design making it ideal for installation into space-constrained and custom housing. 
  • Pre-Certification. The R1511P can be pre-certified in some markets to reduce the overheads of certifying a device from the raw module level upwards.
  • RobustOS Inside. Offers a highly configurable operating system, without the need to develop an environment for the device to interact with. 
  • Increased flexibility. Integrate your embedded router with a wide range of equipment and systems.
