The emergence of Wi-Fi HaLow promotes IoT applications and innovation

Few emerging technologies have the transformative potential of the Internet of Things (IoT). Beyond the increased convenience offered by the billions of smart, connected devices already in homes and businesses, much of the excitement surrounding the IoT is due to its potential promise to reshape the way we connect, communicate, share information, and interact with the world.

Despite all the hype over the Internet of Things over the past decade, the reality is that most supporting wireless technologies are still in their relative infancy, hampered by connectivity challenges such as the limited range and overall functionality of the current Wi-Fi protocol. In short, the Wi-Fi standards currently in use are unable to establish a truly connected ecosystem of smart devices, where hardware can seamlessly communicate with each other over greater distances, regardless of location.

Recognizing that new capabilities are needed to accelerate IoT adoption and innovation, we are working with the Wi-Fi Alliance to develop the Wi-Fi CERTIFIED HaLow program to promote the next generation of Wi-Fi protocols designed to overcome the range limitations of existing wireless standards. Based on the IEEE 802.11ah standard and available through the certification program launching in November 2021, Wi-Fi HaLow extends the range of access points to create more reliable networks throughout a building, campus or property, simplifying the delivery and management of intelligent connectivity solutions for users and service providers.

Features of Wi-Fi HaLow

While Wi-Fi HaLow’s extended range is one of its core strengths (indeed, it’s critical to the maturation of IoT technology), the new protocol also has equally noteworthy features that service providers and consumers should keep an eye on:

• Robust connectivity. In addition to being able to communicate over long distances, IoT devices must also be optimized to penetrate obstacles without the high cost and maintenance of multiple routers and access points. Wi-Fi HaLow is designed to operate using sub-GHz frequency signals, enabling IoT devices operating in this band to transmit data over longer distances and more easily penetrate structural obstacles.

• Energy efficiency. The battery-powered designs of many IoT devices require considerable power reduction techniques. By using duty cycling and other automatic power saving techniques, coupled with lower overall transmit power, Wi-Fi HaLow enables connected devices to remain functional for extended periods in low-power modes, minimizing the need to recharge or replace batteries.

• Enhanced security features. Security concerns abound when it comes to protecting smart, connected devices from increasingly prevalent and sophisticated cyberattacks. In fact, cybersecurity experts warn that the rapid growth in IoT adoption over the past year could lead to an increase in hacker attacks on connected devices. This is a legitimate concern, especially as it relates to the integration of IoT technology in smart homes as well as business access systems, vehicles, and medical devices.

Wi-Fi HaLow is designed with enhanced security features from the Wi-Fi Alliance, using the latest authentication and encryption standards to contain and prevent signal interception from outside factors.

Due to these features, Wi-Fi HaLow offers the following advantages:

• Reliability. Wi-Fi HaLow’s low power consumption and extended range enhance the reliability of home security systems, making it easier for homeowners and businesses to manage security settings and remotely monitor homes and facilities without having to worry about devices losing power or signals not being able to penetrate obstructions or communicate seamlessly with other devices over long-range networks.

• Affordability. Wi-Fi HaLow is designed as an affordable alternative to existing wireless protocols. Due to its low data rate, long-range capability, and minimal power consumption, Wi-Fi HaLow can significantly reduce infrastructure, data transmission and maintenance costs, as well as the total cost of ownership associated with individual IoT devices.

• License-free. Wi-Fi HaLow does not need to pay license fees by operating in unlicensed sub-GHz bands. This reduces the need for service providers and means that anyone can operate an AP. As a result, IoT solutions are not only more accessible to ordinary consumers, but also more cost-effective to deploy in large factory or warehouse environments, while contributing to the development of smart homes and urban infrastructure.

Meeting the transformation challenge

• Compatibility with existing devices. One of the main challenges is ensuring compatibility with existing IoT devices. Retrofitting or upgrading devices to support new protocols can be expensive and time-consuming. To address this, conduct a comprehensive assessment of the existing IoT infrastructure to determine device compatibility with Wi-Fi HaLow. Develop a phased implementation plan to gradually replace or upgrade devices, prioritizing mission-critical systems.

• Staff training and knowledge. Implementing Wi-Fi HaLow requires a deep understanding of the technology and its benefits. IT staff may face challenges managing and maintaining the new protocol. This makes it important to invest in a training program for IT staff. Engage with industry experts or Wi-Fi Alliance resources to ensure staff are aware of the latest developments.

• Cybersecurity and privacy issues. Transitioning to Wi-Fi HaLow involves adopting new security protocols, which can be complex and require attention from IT security teams. That’s why it’s important to work with security experts to review and implement Wi-Fi HaLow’s enhanced security features. Develop comprehensive security policies and guidelines to maintain the integrity of your IoT network.

The next step towards a seamlessly connected future

Wi-Fi HaLow is becoming increasingly popular in the IoT ecosystem, from smart homes to smart factories and cities. There is every reason to believe that Wi-Fi HaLow is the missing link to accelerate IoT adoption and innovation. Its ultimate impact on the way we communicate and interact, both individually and collectively, will be revolutionary.
