Managing and Overcoming the Challenges Presented by Global 4G/LTE IoT Deployments

This white-paper from Robustel introduces the challenges of and Robustel’s solutions to LTE Frequency fragmentation & expensive mandatory and operator certification requirements.

This Whitepaper consists of 5 sections:

  • Introduction
  • Problem One: LTE Fragmentation
  • Problem Two: Certifications – Mandatory & Operator
  • Robustel’s Solution to Global Deployment Challenges
  • Conclusion

“LTE Fragmentation” is a complex way of saying that there are lots of different frequencies used around the world for 4G and many of them are incompatible with each other. In fact, if we look at how difficult global deployments have become it makes for quite surprising reading:


The number of 2G bands required to achieve Global coverage


The number of 3G bands required to achieve Global coverage


The number of 4G bands required to achieve Global coverage

Key Challenges

4G Frequencies

4G LTE is delivered on a wide range of bands – a problem that has traditionally been expensive or difficult to solve.

Costly Certification

Robustel’s investment in costly certification for cost-effective 4G routers means OEMs can disown this challenge without an onerous cost penalty.

Risk Reduction

Robustel committed to sending one of its GLOBAL routers with a well-known brand of roaming SIM around the world and achieved 100% success rate.

Remote Access

Getting an inbound connection in the way required by an OEM’s electronic equipment is often an afterthought, and can be a significant stumbling block.
