Narrow band Internet of Things (NB-IoT), is a Low Power Wide Area Network (LPWAN) radio technology standard.
NB-IoT enables wider wireless communication and applies to all walks of life outdoor.
NB-IoT focuses on the low-power wide-area (LPWA) IoT market, which is an emerging technology and widely applicable around the world. Adopting licensed band, NB-IoT can coexist with the existing network in three deployment modes, including in-band, protection band or independent carrier wave.
Long-Term Evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals. The goal of LTE is to increase the capacity and speed of wireless data networks using new digital signal processing (DSP) techniques and modulations that were developed around the turn of the millennium. A further goal is the redesign and simplification of the network architecture to an IP-based system with significantly reduced transfer latency compared with the 3G architecture.
LTE Cat. M
LTE Machine-to-Machine (LTE-M) is a cellular technology developed from LTE, which is introduced as low-cost LTE (LC-LTE) in 3GPP Release 12 specifications and LTE enhanced MTC (eMTC) in Release 13. LTE-M is specifically designed for the needs of IoT applications through an existing carrier wave. eMTC provides the broadest range of IoT capabilities, delivering up to 1 Mbit/s of throughput while utilizing just 1.4 MHz of bandwidth. It is designed to fully coexist with the existing LTE infrastructure. In the continuous evolution of LTE, the latest eMTC and NB-IoT further optimize the system cost, enhance endurance, and expand coverage. The key capability of eMTC is to support mobility and can be located at a cost of only 25% of the Cat1 chip, which is four times higher than the GPRS rate.
LTE User Equipment (UE) Category
LTE UE category is the set of information (parameters) that defines the maximum throughput for the user equipment. Different categories offer different properties for the 4G LTE delivered. LTE Cat. 4 and Cat. 6 indicate LTE network access capabilities of user equipment are 4 and 6 respectively. The higher the category is, the faster the transmission speed gets, while the response cost increases accordingly.
4G LTE features high-speed communication. LTE Cat. 1 provides a maximum of 10 Mbit/s downlink speed and 5 Mbit/s uplink. LTE Cat. 4 reaches up to 150 Mbit/s downlink speed and 50 Mbit/s uplink.
Low rate, low power consumption, and narrow band also keep NB-IoT chip and module cost-effective, the cost of which is almost equivalent to 2G module.
Powerful Connection Capacity
With the same base station, NB-IoT can provide 50-100 times the number of connected devices that existing wireless technologies do. One sector can support 100,000 connections.
With a strong indoor coverage capacity, NB-IoT provides an increment of 20 dB gain higher than that of LTE, which is equivalent to a 100-fold increase in coverage capacity.
Smart 4G LTE technology can more accurately respond to different commands. The searched data will be transmitted to the user's mobile phone after analyzing, processing, and organizing.
