After the read, you will learn the characteristics of the 6 wireless protocols IEEE protocols: LoRa, NB-IoT, ZigBee, Wi-Fi, BLE, WiMax.

The other category of LPWAN wireless protocols is 2G/3G/4G cellular communication technologies that work in licensed spectrum and is supported by 3GPP, such as EC-GSM, LTE Cat-m, NB-IoT, etc.

The Narrow Band Internet of Things (NB-IoT) is an important branch of the Internet of Everything.

Built on cellular networks, NB-IoT consumes only about 180 kHz of bandwidth and can be deployed directly on GSM, UMTS, or LTE networks to reduce deployment costs and enable smooth upgrades.

LoRa vs NB-IoT, What is the difference between the two LPWAN technologies?

NB-IoT is established based on cellular technology, and its service quality is relatively high and recognized by many operators.

Due to the designation of international standards, in addition to the implementation of regulatory policies, operators have vigorously promoted Narrowband-IoT technology, which has been widely used in network deployment and has obvious advantages in public networks as well as carrier-grade phase networks.

What are the differences and relationships between LTE-M and NB-IoT?

LTE-M, or LTE-Machine-to-Machine, is an LTE evolution-based IoT technology, called Low-Cost MTC in R12 and LTE enhanced MTC (eMTC) in R13, designed to meet the needs of IoT devices based on existing LTE carriers.

Built on cellular networks, NB-IoT consumes only about 180 kHz of bandwidth and can be deployed directly on GSM, UMTS, or LTE networks to reduce deployment costs and enable smooth upgrades.

In general terms, IoT technologies are divided into two broad categories: WLAN IoT (short-range) and cellular IoT (long-range).

WLAN IoT: represented by Wi-Fi, Bluetooth, Zigbee, Z-wave.

Cellular IoT: represented by NB-IoT, eMTC, LoRa, Sigfox.

UWB technology is the best and most advanced positioning technology available today, and why?

This chapter explores the inner workings of UWB technology and provides an overview of the differences between UWB technology and narrowband positioning methods. In addition, the chapter explains how to select the best system architecture for different applications or use case scenarios.

Another system consideration is the UWB antenna. Different applications will require different antennas. For example, tags typically use small omnidirectional antennas. Anchor points, on the other hand, may want to use directional antennas, depending on the topology.

After the analysis of LoRa vs ZigBee technologies, you will learn about what is the difference between LoRa and ZigBee technology.

There are various wireless technologies in IoT applications, which can form LAN or WAN. The wireless technologies for LAN mainly include Wi-Fi at 2.4 GHz, Bluetooth, Zigbee, etc. The wireless technologies for WAN mainly include 2G/3G/4G, etc.

This solution changes the previous trade-off between transmission distance and power consumption and provides users with a simple system that enables long-distance, long battery life, and high capacity, thus extending the sensing network. Currently, LoRa operates mainly in global free bands, including 169 MHz, 315 MHz, 433 MHz, 868 MHz, 915 MHz, etc.

This article briefly discusses the update from WiFi 6 to 5G technology under the weight of a massive number of connected devices.

The next few years will see major changes in all the wireless technologies around people: WiFi 6, the next generation of WiFi technology, Bluetooth 5, the more powerful Bluetooth standard, and of course 5G, the next generation of cellular networks, all of which will play an important role in the upcoming hyper They will all play an important role in the coming era of connectivity, making it easier to connect people and things.

You'll hear a lot of talk about the new 5G as every carrier, chipmaker, and device maker manages to gain 5G dominance. But the answer to what 5G really means is not unique.

For starters, in some cases, 5G doesn't make any sense. U.S. carrier AT&T decided to replace the LTE signal indicators on some phones with "5G E". Although users are connected to a faster LTE network, it's still a 4G network.

Before we talk about what is new 5G technology, let's start with a basic electromagnetic wave principle, which is: speed of light = wavelength X frequency.

The so-called 5G communication refers to the 5th Generation Mobile Networks, which is a generic term for the next generation of communication networks after the maturity of 4G communication technology, which is nothing more than the pursuit of faster speed and lower latency.

Although the international standard for 5G has not yet been fully determined, it can roughly cover two mainstream frequency bands, one is sub 6GHz (that is, below 6GHz), which is not much different from the 4G LTE band we currently use; the other is above 24GHz, which is the millimeter-wave band that we have heard a lot recently.
