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.

There are various wireless technologies applied in industrial personnel location systems, which can form local area networks or wide area networks. Today we will mainly discuss the Lora vs Wifi positioning technology difference.

Before discussing the Lora vs WiFi positioning technology, we need to understand the positioning principle.

LoRa antennas are used in remote meter reading, security systems, access control systems, real-time positioning, and other fields.

Antennas are a key part of the RF chip and are particularly important when choosing the best antenna for LoRa devices (such as LoRa nodes and LoRaWAN gateways) that transmit and receive data in the RF band.

It can be understood that there are different antenna types on the market, such as Lora spring antenna, Lora fiberglass antenna, Lora magnetic antenna, Lora rubber duck antenna, flexible PCB/PCB Lora antenna, etc. When choosing an antenna, it is not the form itself that is important, but the parameters of the antenna and the site environment.

IoT geolocation is one of the most powerful and fast-growing IoT applications, and Market Insight Reports that the market for the "Internet of Things with geolocation" is expected to grow from $40 billion today to $74 billion by 2025.

This is because traditional GPS technology, which has enabled geolocation in the past, is costly, faces technical challenges to its successful deployment, and requires high power consumption to operate.
