NB-IoT: Narrowband IoT Technology for Connected Devices
What is NB-IoT?
NB-IoT (Narrowband Internet of Things) is a Low Power Wide Area Network (LPWAN) technology designed specifically for IoT applications. Standardized by 3GPP, NB-IoT operates within licensed spectrum bands, providing reliable, secure connectivity for devices that need to transmit small amounts of data over long distances while consuming minimal power.
As pioneers in NB-IoT device development, Accent Systems has been at the forefront of this technology since its early adoption, delivering certified NB-IoT solutions to customers worldwide.
Key Benefits of NB-IoT Technology
🔋 Ultra-Low Power Consumption
NB-IoT devices can operate for 10+ years on a single battery, thanks to Power Saving Mode (PSM) and extended Discontinuous Reception (eDRX). Ideal for deploy-and-forget applications.
📡 Extended Coverage
With 20dB improvement over LTE, NB-IoT signals penetrate deep indoor locations, underground facilities, and rural areas where traditional cellular fails.
🔒 Carrier-Grade Security
Operating on licensed spectrum with LTE-level encryption, NB-IoT provides enterprise-grade security without the interference issues of unlicensed bands.
💰 Cost-Effective Deployment
Leverage existing cellular infrastructure with no need to deploy private gateways. Low module costs and affordable data plans make large-scale deployments viable.

Our recommendation: Choose NB-IoT for stationary applications requiring maximum battery life and deep coverage. Choose LTE-M when mobility, lower latency, or higher throughput is needed. Many of our devices support both technologies for maximum flexibility.
NB-IoT Applications
🚚 Asset Tracking & Logistics
Track containers, pallets, and high-value assets across global supply chains. NB-IoT’s coverage ensures connectivity even in remote locations and inside metal containers. Our NB-IoT trackers provide accurate location data with years of battery life.
🏭 Industrial IoT & Smart Manufacturing
Monitor equipment conditions, environmental parameters, and production metrics in factories. NB-IoT’s deep indoor penetration makes it ideal for industrial environments with challenging RF conditions.
🌆 Smart Cities
From smart parking sensors to environmental monitoring stations, NB-IoT enables massive IoT deployments across urban infrastructure. Support for millions of devices per cell makes city-wide rollouts practical.
⚡ Smart Metering & Utilities
Gas, water, and electricity meters benefit from NB-IoT’s ability to reach basement installations and underground infrastructure. Extended battery life means meters can operate maintenance-free for their entire service life.
🌾 Agriculture & Environmental Monitoring
Monitor soil conditions, water levels, and weather data across large agricultural areas. NB-IoT’s rural coverage and low power consumption make it perfect for remote monitoring applications.

NB-IoT stands for Narrowband Internet of Things. It’s a low-power wide-area network (LPWAN) technology standardized by 3GPP in Release 13 (2016).
What frequency does NB-IoT use?
NB-IoT operates in licensed LTE frequency bands, typically in the 700-900 MHz range for optimal coverage. It uses only 180 kHz of bandwidth, allowing deployment in guard bands, standalone spectrum, or within LTE carriers.
How long does an NB-IoT battery last?
Depending on the application and transmission frequency, NB-IoT devices can achieve 10+ years of battery life using Power Saving Mode (PSM) and a standard AA or lithium battery.
Is NB-IoT the same as 5G?
No, but NB-IoT is part of the 5G ecosystem. 3GPP has confirmed that NB-IoT will continue to be supported in 5G networks as “5G NB-IoT” for massive IoT applications.
What is the range of NB-IoT?
NB-IoT leverages existing cellular infrastructure, so coverage depends on the carrier network. The technology provides approximately 10km+ range in rural areas and excellent deep indoor penetration in urban environments.
