LTE / 4G standard / Narrowband IoT

The fourth generation of mobile phone standards LTE (Long Term Evolution) offers an up to seven times faster upload speed with upload speeds of up to 50mbps. Retrofitting the infrastructure of UMTS (3G) to LTE-Advanced (4G) will not be a hurdle, as the basic scheme of UMTS persists. In addition to the higher capacity, the benefits of 4G LTE are the significantly lower latency times. These play a key role in the smooth retrieval of IoT applications that rely on real-time information, such as data from production systems or traffic information.

Another advantage of LTE: Narrow Band IoT (NB-IoT). This is a new mobile network, which is based on the LTE standard and is used exclusively for IoT applications. Compared to mobile networks (2G, 3G and 4G), NB-IoT offers energy-saving capabilities that increase the battery life of simple IoT applications up to 10 years.

This technology is used for communicating with "things", which transfer only small amounts of data over long periods of time and are located in hard-to-reach places.
The LTE Narrowband technologies Cat-M1 and Cat-NB1 already provide alternatives to the 2G standard, which has already been shut down in some countries.

What Is Narrowband IoT – And What Are Its Implications For The Internet Of Things?


If you’re interested in the Internet of Things (IoT) and associated technologies, you may have heard about “NB IoT” “Narrowband IoT” “Narrowband LTE 4G” or other related buzzwords. If you’re not sure what, exactly, all of this means, you’re not alone. That’s why the team at Round Solutions is here to discuss the basics behind 4G LTE and Narrowband IoT.


Narrowband IoT – Low Bandwidth, Low Power Consumption Networks For IoT Devices

Without getting too technical, narrowband IoT is just an extension of existing 4G LTE technologies. However, it’s designed especially for IoT devices that do not require a lot of bandwidth or computing power. Traditional LTE signals are designed to be used in computers, smartphones, tablets, and other devices that use a lot of computing power, and require a lot of bandwidth. For that reason, they require quite a bit of power to use – and the chips used for 4G LTE technology are quite expensive. This makes traditional 4G LTE signals a bad fit for IoT devices, such as temperature sensors or other data monitoring sensors, which only need to transmit small amounts of data infrequently. For example, it would not make sense to use 4G LTE for an atmospheric pressure sensor that sends data to a computer once a week. It’s just not necessary. This is why Narrowband LTE has been developed. NB-IoT technology has been designed to offer connectivity to these low-power, low-bandwidth pieces of equipment – allowing them to stay connected to the network without requiring excessive power consumption.
While there are other IoT-focused LTE bands, such as LTE-M, NB-IoT is designed to be even more effective for use with mobile IoT devices.

The Benefits Of NB IoT Technology


Low Power Consumption

► Battery powered units may experience lifetimes of 10 - 15+ years, without requiring recharging or an external power source.

More Reliable Connections

► NB IoT technology will ensure better connectivity and deeper signal penetration, especially inside buildings.



Cost Savings

► NB-IoT will be inexpensive to use, and chipsets supporting the technology will be cheap enough to allow mass deployment of IoT devices that utilize this new technology.

Narrowband LTE – A Critical Element Of Our Connected World

As time goes on, our reliance on internet-connected devices is likely to increase. Experts have predicted that there will be more than 26 billion connected IoT devices by 2020 – and low power consumption, low-bandwidth signals such as NB-IoT LTE signals are going to be critical as this technology continues to develop. Currently, work is still ongoing in the U.S. to develop an ongoing Narrowband LTE infrastructure. Telecom giant Verizon has begun the process of establishing NB-IoT networks – and telecommunications companies all over the world are following suit.

Narrowband LTE – The Future Of Internet Connectivity

Narrowband LTE is not designed to replace standard 4G LTE coverage and other mobile networks. Rather, it is built to work alongside them – providing reliable, inexpensive performance for low-powered IoT devices. The potential of Narrowband LTE is massive. Using NB-IoT technology, it will be easier than ever for consumers, commercial companies, and industrial firms to use the power of IoT connectivity to their advantage – and change our world for the better.
