There are multiple choices for LPWAN, each with their own specialties that help them differentiate themselves from the others. Verizon, the U. They simply need to upload new software as long as the devices operate within its LTE network. The existing customer bases of these two companies will most likely hear that Cat-M is by far the superior option. Perhaps one of the most innovative things for Cat-M1 is that it's the first LTE based hardware architecture designed specifically for low-power and low-cost IoT applications.
In the past, the hardware was always evolving with faster data rates to support broadband phone, tablet, etc applications. To prolong the battery life, it introduces special power mode for UE Rel.
UE decides how often and for how long it needs to be active in order to transmit and receive data. Maximum PSM timer is PSM mode is similar to power-off, but the UE remains registered with the network.
This means that when the UE becomes active again there is no need to re-attach or re-establish PDN connections. This eliminates page monitoring between the data transmissions UL. It reduces power consumption by extending the sleeping cycle in idle mode up to 40 min. It allows the device to turn part of its circuitry off during the extended DRX period to save power.

Carriers have begun to deploy these two standards. Read on, and we will explain the basics of the three standards, examine their benefits and limitations and then detail the reasons why you should consider Cat It is a low-power, wide area network LPWAN technology that operates on the licensed spectrum and is designed for IoT devices with low-bandwidth needs.
It is low cost, provides improved in-building coverage, consumes less power, and thus, has a longer battery life when compared to other existing cellular standards.
NB-IoT features uplink speeds of 66kbps and download speeds of 26kbps in half-duplex mode, meaning data goes in one direction at a time.
Know the difference between NB-IoT vs. Cat-M1 for your massive IoT deployment
It also has a latency of 1. NB-IoT operates in a very narrow bandwidth — kHz — and can be deployed in the guard band portion of an LTE network, which is in-between channels in an unused portion of the spectrum. That includes HVAC control, industrial monitors and agricultural sensors that monitor irrigation systems and detect leaks. Cat-M1 offers fast enough bandwidth to serve as a replacement for many current 2G and 3G IoT applications. It is different than NB-IoT in several other ways: Cat-M1 supports cellular tower handoffs, so it works with mobile applications, such as asset tracking and fleet management.
LTE-M vs. NB-IoT: Make the Best Choice for Your Needs
It also supports voice features in IoT applications, such as medical alert devices and home alarm systems where the ability for people to talk is important.
The standard, which uses 1. Furthermore, Cat-M1 supports full and half-duplexing, meaning companies can lower power consumption and increase their battery life by choosing half duplex. Good use cases for Cat-M1 include wearables, such as fitness bands and smartwatches and automated teller machines ATMs in addition to asset tracking, health monitors and alarms. It also has some crossover with NB-IoT and can work with smart meters and industrial monitors.
Cat-1 is designed for IoT devices with low and medium bandwidth needs. Cat-1 — which has widespread adoption among carriers worldwide — offers bandwidth speeds of 5Mbps for uploads and 10Mbps for downloads with a latency of 50 to milliseconds.
It uses up to 20 MHz of bandwidth in full duplex mode and supports tower handoff. The upshot: Cat-1 can manage the low-power applications that NB-IoT and Cat-M1 support, but it can also support higher bandwidth needs because it offers better performance and much lower latency than its two counterparts. Cat-1, which also supports voice and mobile IoT applications, also offers a good migration path for 2G and 3G applications, such as asset tracking, smart meters, and other remote sensors.
Other good use cases include wearables, point-of-sale terminals, ATMs, retail kiosks, video surveillance, connected healthcare, consumer electronic devices, and some vehicle telematics data.
It also supports shared mobility uses, such as bike and scooter rentals, and sophisticated IoT devices, such as digital signage and autonomous drones for deliveries. For higher bandwidth needs, the Cat-4 LTE standard reaches 50Mbps upload and Mbps download speeds and can better handle video surveillance and other real-time video applications as well as in-car hotspots and in-car infotainment. The future 5G cellular networks provide the high-speed, low-latency communications necessary to support autonomous vehicles, remote surgery in healthcare, and other high-bandwidth applications in the future.
Researchers expect steady adoption of IoT devices running on NB-IoT and Cat-M1 networks as more carriers implement the two technologies in the coming years. But while NB-IoT and Cat-M1 offer many benefits, the two technologies currently have some limitations, namely, they are still emerging technologies, and coverage is still limited globally. Global reach and roaming capabilities. Carriers throughout North America, Europe, and Asia have begun adopting one or the other, but because NB-IoT and Cat-M1 are complementary technologies, some carriers are choosing to support both.
In fact, out of service providers that have deployed either NB-IoT or Cat-M1, nearly 25 percent have implemented both as of Novemberaccording to the Ericsson Mobility Report. However, while carriers are making progress with the adoption of NB-IoT and Cat-M1, they are not widely deployed globally yet.
That, in turn, limits roaming capabilities. If your company has a specific IoT use case that requires roaming between carriers on Cat-M1 networks today, it may not be possible because of the still limited adoption rates. Is it really low-power? The new standards also include some additional power-saving features that can further reduce power consumption and extend the battery life of IoT devices.
However, these highly touted features may not live up to their promises because carriers might not fully support them.IoT technology is unlocking game-changing results in business, industry, and almost every type of enterprise.

Understanding the differences in available offerings is important when it comes to selecting the option that best suits the requirements of the deployment. As the name suggest, Massive IoT is the deployment of an immense amount of low-complexity devices that do not need to communicate with great frequency. Performance does not need to be high, and low transmission latency is not a requirement. Typical use cases include low-cost sensors, meters, wearables and trackers.
Many of these can be deployed in challenging radio environments, such as a basement of a building or on a moving piece of machinery, and will be relied upon to send occasional signals for up to 10 years, without a change of battery. This makes power consumption and conservation critical aspects. While very complementary to each other, they are addressing different types of use cases based on the strength of the capabilities of the two technologies.
NB-IoT supports ultra-low complexity devices with very narrow bandwidth, kHz. Due to its narrow bandwidth, the data rate peaks at around kbs per second. On the other hand, Cat-M1 operates at 1. The wider bandwidth allows Cat-M1 to achieve greater data rates up to 1 Mbpslower latency and more accurate device positioning capabilities. Cat-M1 supports voice calls and connected mode mobility. Furthermore, both technologies support enhanced signal coverage per base station. With extreme coverage capability, NB-IoT is ideal for supporting very low data rate applications in extremely challenging radio conditions.
Most common use cases of NB-IoT include utility meters and sensors. Typical uses cases for Cat-M1 include connected vehicles, wearable devices, trackers and alarm panels. For example, if you have an oil tank in a basement of a building that needs a sensor to check its level from time to time, NB-IoT will be your choice the elevator servicing that basement, however, will use Cat-M1.
From an operator perspective, NB-IoT also creates more deployment flexibility due to guard-band deployment. Each standard has specific use cases, so understanding those differences will be key to forming a Massive IoT strategy.
