Today, we talk about the LTE Cat 1 vs Cat 4. After the read, you will know about the difference between LTE Cat.1 and Cat.4.

To distinguish between LTE Cat.1 and Cat.4, we need to know what Cat is. Cat stands for Category, and the numbers after Cat represent the different categories, which 3GPP names in the Cat.

Cat.X is used to describe the capability level of user terminals according to the 3GPP Release definition, and Cat4 and Cat1 are both standards for user terminal categories in LTE networks for 4G communications.

Today, we talk about the 5G NR technology and the 6 Characteristics of 5G NR Technology.

What is 5G NR technology?

The 5th generation mobile networks or 5th generation wireless systems, 5th-Generation, referred to as 5G or 5G NR technology is the latest generation of cellular mobile communication technology, namely 4G (LTE-A, WiMax), 3G ( Extension after UMTS, LTE) and 2G (GSM) systems.

5G NR technology has set a new standard for wireless, opening up the spectrum above 6 GHz that has been previously unusable by cellular services.

The relationship between 5G NarrowBand IoT

What relationship exists between 5G NarrowBand IoT? Whether Narrowband IoT is 5G technology in the end? Today, we will learn about the 5G Narrowband IoT relationship.

5G NR technology brings by no means only faster network speed, but will be the intelligent interconnection of everything is possible in fact, and NB-IoT is the prelude and foundation of 5G commercialization, therefore, the evolution of NB-IoT is more important, such as support for multicast, continuous mobility, new power levels, etc. As long as the infrastructure such as NB-IoT is complete, 5G New Radio can be truly realized.

Industrial IoT is relatively a regional network, so there is a possibility of a breakthrough. NarrowBand IoT bypasses 4G, no need to wait for the arrival of the 5G era all the time, 5G narrowband IoT takes the lead to come out and lead the way.

Despite the hype of 5G NR, Wi-Fi and 5GNR together play an important role in corporate use cases such as remote patient care and smart manufacturing. How 5G Enhances WiFi in the industries?

5G new radio is a very new technology. In addition to faster speeds, when 5G is actually implemented.

The dramatic claim that New 5G will replace WiFi is unfounded to New Radio 5G? It doesn't work today.

Few industries are as affected by 5G as manufacturing. In the manufacturing industry, the advent of cellular technology could stimulate the next industrial revolution.

Most factories continue to operate on Wi-Fi networks, but the wave of smart factories based on 5G technology is beginning to emerge.

Today, we talk about the wired and wireless IoT Communication Technologies, the simple 13 common communication technologies in IoT.

We have compiled and summarized the commonly used wired and wireless communication methods of IoT for future reference.

Communication frequency band: license-free frequency band. Use Industrial Scientific Medical (ISM) frequency band, 915MHz (U.S.), 868MHz (Europe), 2. 4GHz (Global)

NB-IoT is built on a cellular network and only consumes about 180KHz of bandwidth, and can be directly deployed on a GSM network, UMTS network, or LTE network.

From 12 perspectives on Narrowband IoT vs Lora technology to learn which IoT standard is more advantageous.

Rapid developments in machine learning and M2M communication standards are playing a key role.

Semtech's LoRa technology is a bit ahead of the curve in this area, but NB-IoT (narrowband IoT) is also rapidly gaining traction as a powerful LPWAN standard.

Lora and LoRaWAN are often used as synonyms, but they do not refer to the same thing.

NB-IoT works well in urban areas but has only mediocre performance in suburban and rural areas (where 4G signal is not available).

LoRaWAN does not rely on cellular data or Wi-Fi, so it can maintain relatively stable coverage in any region.

Note: Compared to the cost of constructing base stations for 4G-LTE, which is necessary for the introduction of NB-IoT, the cost of constructing base stations for LoRa is a fraction of that for 4G-LTE, and the low investment required gives LoRa a significant advantage.

Today, we talk about something about NB-IoT which you may not know.

NB-IoT refers to Narrow Band - Internet of Things (IoT) technology, which focuses on the Low Power Wide Area (LPWA) Internet of Things (IoT) market and is an emerging technology that can be widely used around the world.

Huawei, as the domestic leader in developing NB-IoT technology, has also attracted considerable attention from the technology community.

Q: How are the frequency bands for NB-IoT divided by domestic and international operators?

A: Most operators worldwide use the 900MHz band to deploy NB-IoT, and some operators deploy in the 800MHz band.

China Unicom's NB-IoT is deployed in the 900MHz and 1800MHz bands, and currently, only 900MHz is available for trials.

The cellular IoT is a method of connecting physical devices (sensors, etc.) to the Internet, and transmits physical devices (sensors, etc.) on the same mobile network as smartphones.

The cellular network connects IoT devices will exceed 20 billion in 2023. Specifically, the number of IoT devices connected via LTE and 5G exceeds 3.5 billion, mainly in China and Northeast Asia.

Two major forms of cellular Internet of Things: LTE-M and NB-IoT

In fact, all current cellular IoT applications use either LTE-M or NB-IoT or GSM cellular infrastructure.

While only the United States, the Netherlands, Ireland, and Australia cover national LTE, GSM has become the norm in many non-Western regions such as Eastern Europe and Africa.
