LTE-M OR NBIOT: WHICH IS BETTER
WHAT IS A LOW-POWER WIDE AREA NETWORK (LPWAN)?
LPWAN (Low-power Wide Area Network) is a wireless network technology that links low-bandwidth, low-power consumption devices across long distances with low bit rates, enabling additional M2M and IoT applications that were previously cost prohibitive.
LPWAN refers to a collection of low-power, wide-area network technologies. It can employ licensed or unlicensed frequencies, as well as proprietary or open standard alternatives.
LTE-M AND NARROWBAND-IOT (NB-IOT)
Narrowband Internet of Things (NB-IoT) and LTE-M are both 3GPP protocols that run on licensed spectrum. While they perform similarly to other standards, they use existing cellular infrastructure, allowing service providers to swiftly add cellular IoT connections to their service portfolios.
LTE-M and NB-IoT low-power wide-area networks are built and optimised for IoT connection and M2M communication.
NB-IoT, also known as CAT-NB1, runs on current LTE and GSM infrastructure. NB-IoT is being developed to provide for effective connectivity and long battery life in widely deployed devices.
This standard was developed in collaboration with 3GPP because to its benefits such as power efficiency, cost savings, reliability, wider deployment, deep penetration, and global reach.
NBIoT is designed to provide efficient communication and extended battery life for widely spread devices, and it connects devices using pre-existing mobile networks.
NBIOT ACTIVATES IN ONE OF THREE WAYS:
Independently
In previously underused 200-kHz bands originally used for GSM (Global System for Mobile Communications)
On LTE base stations, a resource block is assigned to NB-IoT activities or in their guard bands.
Despite having lower bitrates, it is ideal for applications where data is acquired by sensors and delivered for processing.
Low cost: NB-IOT modules are less expensive than modules and subscription fees for other communication technologies on the market, such as 3G, 4G, and LTE-M.
More cellular towers per cell tower: Because NB-IOT devices consume 180 kHz bandwidth, the network is expected to accommodate more than 50000 connections per cell tower.
Uplinking and Downlinking Speed: up to 62.5kbps
Excellent indoor and subterranean penetration.
Home/building automation, Smart metering, smart cities, and smart grid applications are all possible.
LTE-M (also known as CAT-M1 or LTE-MTC) has a faster data rate, mobility, and voice over the network than NB-IoT, as well as the highest bandwidth of any LPWAN technology.
It has a bandwidth of 1.4MHz.
Uplink and downlink speeds: up to 1 Mbps, which is significantly faster than NB-IoT.
VoLTE: Voice mobility is supported: For gadgets in motion
Fleet management, tracking, retail & POS, wearable gadgets, and asset monitoring applications are all possible.
The primary distinctions between NBIoT and LTE-M are cost, latency, and speed.
For IoT applications, the revolution has already begun in the shape of LTE-M and NB-IoT; it is future-proof and will be supported for many years to come with 5G, and it is therefore firmly on the route to 5G.
PsiBorg Technologies a Full stack IoT Development has developed IoT solutions using both NBIoT and LTE-M, and we have extensive experience in the industry.
