Industry 4.0 involves interconnected cyber-physical systems where a network of intelligent devices, including handheld terminals, automated guided vehicles (AGVs), robots, cameras, and multimedia equipment, exchange data to improve operations. Reliable communication technology is essential, especially in the automating manufacturing sector, where operational efficiency and real-time data access are critical for staying competitive. QLink Super Wi-Fi™ provides robust connectivity that supports automation and IoT devices, facilitating effective device communication and real-time monitoring systems. This enhances productivity, reduces downtime and costs, and ultimately improves operational outcomes.
Wi-Fi facilitates wireless communication between handheld devices (tablets, laptops, PDA) and Manufacturing Execution System ( MES ), enhancing operational efficiency in:
Wi-Fi connects Vehicles to the CMS for:
Wi-Fi supports multimedia equipment, allowing data transmission over wireless. This capability enables:
Wi-Fi supports diverse IoT devices and sensors, allowing for seamless connectivity and data transmission to central system. This capability enables:
Manufacturing factories are typically large sheds clad in metal and filled with metal structures and/or heavy machinery. Examples would include racking and shelving systems and safety cages around moving equipment. These elements can create physical and/or electromagnetic barriers that obstruct Wi-Fi signals
WiFi signals can be disrupted by interference from electronic devices such as machinery or equipment that emits electromagnetic radiation. This interference can degrade the Wi-Fi signal quality, resulting in slower speeds and unreliable connections.
Many wireless devices, such as sensors, RFID tags, and handheld terminals, operate simultaneously in a manufacturing environment. This high density of devices can congest wireless networks, leading to delays and reduced throughput.
Limited by the roaming capability, some legacy WiFi client devices stick to the weak signal to cause low transmission data throughput and a lot of delay. Packet loss is not allowed for mission-critical applications during roaming.
Manufacturing environments require robust security measures to protect sensitive data and prevent unauthorized access. Without proper security, wireless networks can be vulnerable to interception or hacking, posing a risk to operational integrity.
QLink patented smart antenna technology increases Wi-Fi coverage while minimizing the number of access points needed, resulting in reduced capital and operational expenditures.

The smart antenna technologies enable more robust performance in highly interfered areas. In case of interference in one sector, the other sectors of the multiple antenna’s system can still work properly.
By utilizing the built-in automatic channel selection feature, the system will automatically select the channel with the least interference. This automatic channel selection can be scheduled at a predefined time, ensuring that the system is consistently refreshed to the best available channel.

OFDMA and MU MIMO for enhanced multi user efficiency and speed. Other features such as 1024 QAM of modulation, BSS coloring and Target Wake Time also help optimize QLink WiFi6 AP model’ s performance.
QLink AirFi TM enhances AP’s capacity by optimizing the client s throughput based on their speed and data volume.
Band Steering: AP steers dual-band clients to the radio of lower channel utilization. This helps optimize and balance the channel airtime utilization between 2.4G and 5G radios and therefore enhance wireless performance and experience.
Multiple AP Steering: Help client to select the best possible Wi-Fi link from different APs based on the AP radio utilization and Link quality between AP and client.

Fast Handover – Enhanced active background scanning and roaming threshold enable QLink CPE to have a handover time of 80~100 ms
Smart Roaming – QLink AP proactively monitors client connection status and uses standard (802.11k/v/r) or non-standard mechanisms (client RSSI/PER) for facilitating client roaming to mitigate the effects of poor handover decisions made by clients alone
Zero Packet Loss – The QLink APs involved in roaming communicates with each other to enable intelligent packet buffering and forwarding, reducing packet loss to zero

To accommodate the needs of delay-sensitive and mission-critical applications, QLink offers AlwaysConnected solutions. It is a setup consisting of multiple wireless links, one in active and the rest in standby, to provide robust and loop-free connectivity. Since the links are already in place, the system can simply do the link switching in no time when the active links becomes poor.
With QLink proprietary protocol used in AlwaysConnected solutions, the link switching time can be achieved down to 10 ms.

Various of User Access Security modes are supported by QLink Solution for different security requirement: WPA2 and WPA3, 802.1X/EAP, MAC ACL, VLAN Assignment, Layer 2 Isolation
QLink AP provides wireless intrusion prevention system (WIPS) to monitor a wireless network’s airspace to detect unexpected, unauthorized or rogue activities and frequencies. If any malicious or misconfigured device is operating or trying to operate on the network, the WIPS can detect it and automatically shut it down. In doing so, the WIPS can prevent the device from executing malicious attacks against the network and its users.
