Wi-Fi Networks and Security Protocols in 2025

Introduction to Wi-Fi Networks

At VPTS, WiFi networks play a crucial role in connecting and supporting company operations. With growing connectivity needs, VPTS continuously updates and deploys the most advanced WiFi technologies to ensure maximum performance and security. WiFi is a popular wireless networking technology that allows devices to connect to the Internet without cables. WiFi networks use IEEE 802.11 standards to transmit data via radio waves. With technological advancements, WiFi continues to improve in speed, stability, and security.

WiFi has now become an indispensable component in organizations, enterprises, and households. Connection speeds are increasingly faster, the number of connected devices is rising sharply, and security requirements are growing stricter. Consequently, WiFi standards and security protocols are continuously evolving to meet these demands.

Current WiFi Standards

IEEE 802.11ax (WiFi 6)

IEEE 802.11ax, also known as WiFi 6, is the latest generation of WiFi, improving performance and stability compared to older standards such as 802.11ac (WiFi 5). Key features of WiFi 6 include:

• OFDMA (Orthogonal Frequency Division Multiple Access): Improves performance when multiple devices are connected.

• MU-MIMO (Multi-User, Multiple Input, Multiple Output): Allows multiple devices to transmit and receive data simultaneously.

• TWT (Target Wake Time): Reduces energy consumption for IoT devices.

• Higher speed: Wider bandwidth, supporting speeds up to 9.6 Gbps.

• Performs well in high-density environments: Reduces latency and optimizes connectivity with many concurrent users.

IEEE 802.11ac (WiFi 5)

The WiFi 5 standard focuses on high speeds and operates primarily on the 5GHz band. Although still widespread, WiFi 6 has gradually superseded WiFi 5 thanks to performance and security enhancements.

WiFi 6E – Extension of WiFi 6

WiFi 6E is an extension of WiFi 6 that allows the use of the 6GHz frequency band, significantly reducing interference and boosting performance.

WiFi 7 (IEEE 802.11be)

WiFi 7, expected to launch in the future, promises improved speeds and bandwidth, supporting more devices.

WiFi Security Protocols

WPA3 (Wi-Fi Protected Access 3)

WPA3 is the newest WiFi security protocol, replacing WPA2 to provide higher levels of protection. Key characteristics of WPA3 include:

• Stronger encryption: Uses 192-bit AES-GCMP encryption for enterprises and 128-bit AES-GCMP for individuals.

• Protection against password brute-force attacks: Limits incorrect password attempts, helping prevent dictionary attacks

• Perfect Forward Secrecy (PFS): Ensures transmitted data cannot be decrypted even if passwords are compromised.

• Easy Connect: Supports secure connection for IoT devices via QR code or NFC.

WPA2

WPA2 is still widely used but has security vulnerabilities, such as the KRACK (Key Reinstallation Attack) that allows hackers to intercept data over WiFi networks.

WEP (Wired Equivalent Privacy) – No Longer Secure

WEP is the oldest security protocol and is no longer recommended for use due to its vulnerability to easy attacks.

Applications of WPA3 and 802.11ax at VPTS

VPTS Company is implementing the latest Wi-Fi security standards to ensure maximum safety and performance for network systems:

• Deploy WPA3 on the internal WiFi network to enhance data security.

• Use WiFi 6 (802.11ax) to improve connection speed, supporting more users in the workspace.

• Protect systems from common WiFi attacks by using firewalls and continuous network monitoring.

• Integrate advanced security solutions like VPN and IDS/IPS to safeguard critical data.

• Supports IoT networks: Connects smart devices with higher security thanks to WPA3 and WiFi 6.

• Improve work efficiency: Ensures a stable connection, supporting bandwidth-intensive applications like video conferencing and video streaming.

CONCLUSION

WiFi 6 (802.11ax) and WPA3 are major breakthroughs in wireless networking technology, boosting performance and security for the WiFi system of VPTS. Applying new security standards helps the company protect data and provide the best connectivity experience for employees and customers. VPTS is committed to continuing to update the latest technologies to ensure a secure, robust, and reliable network infrastructure.
