Ever wondered what the difference is between “LTE” and “4G”? These terms are often used interchangeably—but they’re not exactly the same. In this post, we’ll explain what each one really means, how they evolved, and why LTE still plays a vital role in modern connectivity—especially in the world of IoT.
The original 4G standard was defined by the ITU (International Telecommunication Union) in 2008. The bar was set high: 100 Mbps for mobile users and 1 Gbps for stationary users. This was meant to usher in a new era of mobile speed, reliability, and efficiency.
Long-Term Evolution (LTE) is the technology path developed by the 3GPP to reach 4G performance, and it was a major leap beyond 3G. However, early LTE didn’t quite hit ITU’s 4G benchmarks. It came close—so close, in fact, that many engineers called it “3.95G.” Still, in 2010, the ITU allowed LTE to be branded as “4G LTE” due to its significant performance gains over 3G.
So “4G LTE” is mostly a marketing term: operators used it to highlight LTE’s big improvement over 3G.
As LTE matured, it evolved into LTE-Advanced (LTE-A), also sold as 4G+, LTE+ or 4.5G, which does meet and exceed the original 4G benchmarks. It introduced features like:
With these upgrades, LTE-A can achieve real-world speeds comparable to the original 4G promise.
| Feature | Early LTE | LTE-A (“4G+”) |
|---|---|---|
| Peak download speed | ~100 Mbps | Up to 1 Gbps |
| Latency | ~15–50 ms | <10 ms |
| Core architecture | EPC (legacy) | All-IP flat core |
In everyday use:
That’s more than enough for HD/4K streaming, large downloads, and video calls. For industrial and IoT applications, LTE means reliable, wide-area connectivity with low power consumption.
LTE is far from obsolete:
This makes LTE essential for smart cities, asset tracking, agriculture, and more.
Industrial-grade LTE hardware is crucial for many mission-critical use cases:
Round Solutions provides industrial-grade LTE/4G modules, including LTE-A and LTE-M/NB-IoT modules from Telit Cinterion, high-performance Sunnyway-IoT antennas, and intelligent edge gateways like the IO-GATE—perfect for demanding industrial, logistics, and infrastructure environments.
The IO-GATE also supports local edge processing, ideal for real-time systems with reduced cloud dependence.
While LTE and 4G started as distinct, LTE-Advanced has bridged that gap. For most users and IoT applications, LTE (especially LTE-A) is 4G. Choosing the right technology depends on your goals—and with Round Solutions, you get expert guidance, robust Telit Cinterion modules, and field-proven antennas built to last.
Founded 1999 in Germany, we are a leading developer of IoT gateways & ODM services and Telit Cinterion's oldest, most trusted and licensed distributor. Round Solutions is proud to announce its partnership with Sunnyway‑IoT, the leading manufacturer of high‑performance IoT antennas in China. This collaboration allows us to offer an expanded range of reliable and innovative antenna solutions tailored to meet the demands of European industries, including automotive, industrial IoT, and smart city applications.
