It's no secret that the proliferation of the Internet of Things (IoT) has meant increasing pressure on wireless networks. Smart buildings are becoming the norm, where a host of devices and applications fight for a connection. But getting down to the why and how of the connectivity issues faced by smart buildings can help uncover solutions and tangible ways forward—since the trend isn't going anywhere anytime soon.
This article covers:
Wireless technologies have adapted to the increase in IoT traffic and the demand for stronger, more consistent connections. Smart devices found in intelligent buildings are equipped with technologies like Bluetooth and Light Fidelity (LiFi), in addition to Wi-Fi.
LiFi uses light to send and receive data via Light Emitting Diodes (LEDs). It's an example of a fast-emerging technology that aims to improve broadband access efficiency while providing the added benefit of more cost-efficient lighting.
Another wireless personal area network (PAN) technology is Bluetooth Low Energy (BLE). BLE's purpose is to provide coverage in smaller areas for benefits like better remote management, and it requires lower power to keep devices connected. BLE uses the underlying Bluetooth technology to better support IoT applications and devices, which typically transmit smaller amounts of data.
While technologies such as these help networks support the onslaught of new IoT devices that make smart buildings smart, it's still crucial that wireless networks are designed to adapt to the emerging equipment and applications to come.
The first place to start when structuring a solid wireless infrastructure in a smart building is the AP design. There are a few best practices and considerations for your APs:
To prepare the right design, it takes a mix of proper AP placement and cable positioning. A few tips for cables include:
AP placement also has huge impacts on wireless network efficiency in a smart building. A successful deployment may require assistance from building designers and owners, in addition to network engineers, as certain architectural features will impact the Wi-Fi, and AP appearance considerations will arise in certain spaces.
Critical considerations for AP placement include:
It's also important to stay adaptable to trends and upgrades in APs caused by increases in IoT congestion. For example, APs now have more channels to receive and transmit information to keep up with the latest Wi-Fi standards, including 802.11ax (or Wi-Fi 6), and these devices are larger.
Another solution for maintaining an IoT-focused wireless network is to deploy sensors that can keep track of usage patterns throughout the smart building. This visibility gives designers the ability to optimize the infrastructure based on density and performance quality, including better AP placement.
Network engineers know just how quickly standards and best practices can change with the introduction of new wireless technologies and IoT equipment. When designing or managing a smart building, part of the job is ensuring that applications and devices are continuously updated, and the infrastructure is redesigned to meet new demands.
Wireless network monitoring (WNM) helps ensure that smart building Wi-Fi continues to perform well through any obstacles. 7SIGNAL's platform gives staff continuous visibility into performance, granting the ability to respond to an issue before a user notices a drop or slowdown. WNM is a smart strategy for addressing new IoT challenges and the requirement for continuous data transmission among numerous connected devices.
