As cities around the world evolve into smart cities, the focus is on optimizing urban functions and improving the quality of life for residents. The integration of Artificial Intelligence of Things (AIoT) is transforming urban landscapes, making them more automated, efficient, and transparent. In this context, Wi-Fi becomes essential, serving as the backbone of a smart wireless network that connects various smart devices across the city. QLink Super Wi-Fi provides an industrial-grade solution tailored for urban environments, offering high-speed, secure connectivity that enhances smart city applications while reducing the number of access points needed, all without sacrificing reliability.
Urban cities are characterized as a forest of concrete, creating a non-line-of-sight environment for Wi-Fi deployment. Buildings can greatly obstruct wireless signals, limiting the effective coverage. The Wi-Fi networks must be strategically designed and planned to optimize the coverage.
Wi-Fi networks must cater to both human users and an extensive array of smart devices. The access points (APs) and backend infrastructure are required to accommodate this high volume of connections.
Given the multitude of devices connected to the network, safeguarding data from malicious users is important. Wi-Fi transmissions must be encrypted in compliance with the latest industry standards to ensure user privacy and prevent data leakage.'
Interference from other Wi-Fi access points or non-Wi-Fi radio systems operating on overlapping frequency bands can adversely affect access point performance. Therefore, it is essential to conduct a thorough site survey and implement careful channel planning across the sites.
To effectively manage a network comprising a large number of APs deployed across the city, a centralized WLAN controller is necessary. This will facilitate streamlined administration, monitoring, and maintenance of the network.
Thanks to QLink’s patented antenna design and advanced signal processing algorithms, the QLink solution effectively addresses significant Wi-Fi bottlenecks and enhances uplink performance in non-line-of-sight (NLOS) environments. This optimization reduces the number of access points required
The QLink Super Wi-Fi solution enables access points (APs) to connect over distances of hundreds or even thousands of meters. This stable and robust wireless link supports high traffic volumes while minimizing the number of AP nodes, resulting in decreased capital and operational costs.
QLink’s solution ensures security for both wireless and wired links. Wi-Fi traffic data is secured using WPA2/WPA3 encryption. These data traffic is guarded by sophisticated CheckPoint Next-Generation Firewall (NGFW) embedded in a network controller.
The complex layout of urban environments, characterized by numerous streets and alleys, corridors. Such a non-line-of-sight environment poses challenges in providing comprehensive Wi-Fi coverage as radio frequency signals experience significant loss during propagation. As a result, the deployment of public Wi-Fi will primarily occur in hotspot modes in high internet traffic areas such as parks, town squares, and tourist attractions.
It is recommended to install QLink access points (APs) on high ground like building rooftops, lamp posts, with adjustable down-tilt antenna to shoot to the target coverage areas. The APs can be interconnected via wired or wireless backhauls to incorporate into a MAN for Internet access. To provide coverage within public transport, Customer Premises Equipment (CPE) can be installed as a wireless anchor with 5GHz wireless backhaul to the network infrastructure, and at the same time providing Wi-Fi connectivity onboard for passengers.
