How Does Narrowband IoT Enable Energy-Efficient IoT Applications?
Narrowband IoT allows IoT applications to use less power, which is one of the many advantages of this technology. The efficient use of network assets makes this a reality.
Because of its low power consumption, narrowband IoT is ideal for IoT devices that function on batteries. If you choose a frequency of 200 kHz, you can convey a few bytes of data over incredibly long distances. Hence, a Narrowband IoT device’s battery may last very long on a single charge.
Narrowband IoT is more efficient in utilizing network capacity while reducing energy consumption than standard mobile networks. This is achieved by discontinuous reception, which involves temporarily disabling data collection while no data is being collected.
These measures will extend the battery’s life and reduce energy needs.
Do Different Narrowband IoT Variants Exist?
Yes, Narrowband IoT (Narrowband IoT) comes in different versions that are made to meet different needs and use cases. Three types of Narrowband IoT you will see most often are-
The In-Band uses the LTE spectrum and infrastructure already in place, which cuts down on deployment time and costs. It is also more reliable and has better coverage than other versions. But it has a drawback: it shares resources with LTE traffic, which can cause problems like interference or traffic jams.
This variation eliminates interference by exploiting unused airwaves between LTE carriers. It is also more reliable and has better coverage than the standalone version. To enable Narrowband IoT, however, needs extra hardware or software updates for current LTE base stations.
This variation benefits from employing a dedicated Narrowband IoT spectrum, ensuring maximum performance and scalability. It also works with older GSM networks better than other versions.
But, it has the drawback of necessitating the allocation of additional spectrum and the implementation of new infrastructure, which raises costs and complexity.
Narrowband IoT also comes in different versions for different regions that work on different frequency bands. For example, in Europe, Narrowband IoT uses the 900 MHz bands, whereas in the United States, it uses the 700 MHz and 1900 MHz bands.

Because to its low data rates, long battery life, and wide coverage, Narrowband IoT is ideal for IoT applications such as smart cities, home automation, and industrial IoT.
What’s the Difference Between Narrowband IoT and LoRa?
When it comes to constructing low-power, wide-area IoT networks, narrowband IoT and Long Range (LoRa) Radio are two of the most popular technologies. The two technologies use distinct approaches to achieving their shared goal of low-power, long-range communication.
The technology at their core is where Narrowband IoT and LoRa diverge. Narrowband IoT is based on cellular technology, whereas LoRa relies on public standards for its chirp spread spectrum transmission.
The locations they cover are also very diverse from one. Due to LoRa’s inability to reach outside of private networks, Narrowband IoT can reach far larger areas than cellular networks alone.
Narrowband IoT is ideal for battery-operated IoT devices because of its low power consumption. While LoRa can function on a very small amount of power, the amount of power it really needs depends greatly on the application.
Unlike LoRa, NB IoT’s data rate capacity makes it a viable option for applications requiring near-instantaneous data transmission and reception. On the other hand, LoRa is ideal for use cases where only very little data amounts need to be sent over very long distances.
What’s the Difference Between Narrowband IoT and LTE-M?
Narrowband IoT and LTE-M are the two most commonly used low-power, large network solutions for the IoT. Although both solutions aim to make it possible for IoT devices to communicate over cellular networks, they operate in quite different ways.
The bandwidth available to devices is a key differentiator between Narrowband IoT and LTE-M. Whereas LTE-M may use a frequency of as much as 1.4 MHz, Narrowband IoT is limited to operating at roughly 200 kHz.
This implies that LTE-M is superior to Narrowband IoT when it comes to transmitting big volumes of data at fast speeds.
The quantity of energy they devour daily also differs significantly. If you need a long-lasting IoT device that runs on batteries, look no further than Narrowband IoT because of its low power requirements.
LTE-M, on the other hand, is ideal for uses that call for greater data speeds and longer battery life since it uses more energy than Narrowband IoT but less than standard cellular networks.
Although both Narrowband IoToT and LTE-M can provide extensive coverage, the former is more suited to indoor use, while the latter excels in outdoor settings.
