Different WiFi technology——Wi-Fi HaLow

With the booming development of Internet of Things (IoT) technology, there is an increasing demand for wireless communication technology that can support a large number of devices, transmit over long distances, and consume low power. Wi-Fi HaLow (based on the IEEE 802.11ah standard) was born to meet these needs. This article will delve into the technical details, advantages and application prospects of Wi-Fi HaLow in the IoT field.

Technical Overview of Wi-Fi HaLow

Wi-Fi HaLow is a new Wi-Fi technology launched by the Wi-Fi Alliance in 2016. It operates in the sub-1 GHz frequency band, usually around 900 MHz. This feature gives Wi-Fi HaLow significant advantages in coverage and penetration capabilities. Compared with traditional 2.4 GHz or 5 GHz Wi-Fi, HaLow's signal can cover a wider area, theoretically up to more than 1 km, and can penetrate walls and other obstacles more effectively.

Technical advantages of Wi-Fi HaLow

1. Coverage

One of Wi-Fi HaLow's biggest selling points is its range that far exceeds traditional Wi-Fi. In open areas, HaLow's signal can reach 1 km or more, making it ideal for applications such as agricultural monitoring, industrial automation and smart cities.

2.Penetration ability

Signals in lower frequency bands have better penetration capabilities, which means Wi-Fi HaLow can more easily pass through walls and other building structures. HaLow can provide a more stable connection in places where traditional Wi-Fi signals are difficult to cover, such as multi-story buildings or basements.

3. Low power consumption design

IoT devices, especially sensors and wearables, often need to run on battery power for months or even years. Wi-Fi HaLow's low-power design means it can help these devices manage power consumption more efficiently and extend battery life.

4. Capacity and compatibility

Wi-Fi HaLow is not only capable of supporting large numbers of devices connected to a single access point and is suitable for dense sensor networks, but it maintains compatibility with existing Wi-Fi technology. This makes it easier for device manufacturers to integrate HaLow into existing products without requiring users to replace existing network equipment.

5. Security

Supports the latest security standards such as WPA3 to protect data transmission security.

How Wi-Fi HaLow is different from other WiFi technologies
The main difference between Wi-Fi HaLow (802.11ah) and other Wi-Fi standards (such as 802.11a/b/g/n/ac/ax, etc.) is its design goals and technical specifications. Here are some key differences between Wi-Fi HaLow and other Wi-Fi standards:

Application prospects of Wi-Fi HaLow

The unique advantages of Wi-Fi HaLow give it broad application prospects in multiple fields:
Smart home: In the smart home field, HaLow can connect various home appliances and sensors, even in basements or areas far away from routers.
Industrial Internet of Things: In industrial environments, HaLow can help realize remote monitoring and control of equipment, improving production efficiency and safety.
lSmart agriculture: HaLow is suitable for agricultural monitoring systems, which can cover vast farmland and monitor key indicators such as soil moisture and temperature.
Urban infrastructure: In smart city projects, HaLow can be used for street lighting, traffic management and public safety monitoring.

Telemedicine: HaLow can connect medical equipment to achieve remote monitoring and data collection of patients.

Wi-Fi HaLow expands the boundaries of Wi-Fi technology and provides new possibilities for wireless connections in the Internet of Things era. Its long-distance coverage, low power consumption and high-capacity connection characteristics make it an important technology in the IoT field. As IoT devices continue to grow, we can foresee that Wi-Fi HaLow will play an increasingly important role in the future wireless communications market.
