In the complex network of fiber-optic connections, Wi-Fi Optical Network Units (ONUs), play a crucial role, facilitating both wired and wireless broadband access in various settings, from homes to businesses. As demand for reliable and fast internet grows, understanding how to choose a suitable Wi-Fi ONU becomes paramount, especially in areas with different network conditions. This article aims to provide insights into the differences between Wi-Fi 5 and Wi-Fi 6, helping users in choosing the most suitable Wi-Fi ONU for their network needs.

Understanding Wi-Fi 5 and Wi-Fi 6

Wi-Fi 5, or 802.11ac, has reigned as the dominant wireless standard for an extended period, furnishing data rates exceeding 1 gigabit and utilizes the 5GHz frequency band for data transmission.

In contrast, Wi-Fi 6, also referred to as 802.11ax, introduces several enhancements over Wi-Fi 5, boasting elevated data rates, increased capacity, improved performance in congested environments, and enhanced power efficiency.

Below, we dissect the key differentiators:




IEEE Standard




Max 3.5 Gbps

Max 9.6 Gbps

Frequency Bands

Uses 5GHz

Uses 2.4GHz and 5GHz

Max Range

20-25 meters

45 meters







Network Security




256 QAM

1024 QAM




  • Speed and Throughput: Wi-Fi 6 outpaces its predecessor with accelerated data rates and superior throughput, thanks to advanced technologies like OFDMA and MU-MIMO, especially in scenarios with multiple connected devices.

  • Capacity and Efficiency: Wi-Fi 6 addresses the issue of network congestion more effectively than Wi-Fi 5, supporting a higher number of simultaneous connections while optimizing performance and latency.

  • Latency: Lower latency is crucial for applications such as online gaming, video streaming, and real-time communication. Wi-Fi 6 introduces features like TxBF and 1024-QAM modulation, which help minimize latency compared to Wi-Fi 5, providing a smoother user experience for latency-sensitive applications.

  • Security: Wi-Fi 6 offer significant advancements in network security compared to Wi-Fi 5, including native support for WPA3 and advanced encryption standards, fortifying networks against emerging cyber threats.

Applications of Wi-Fi5 AC1200 vs. Wi-Fi6 AX1500 vs. Wi-Fi6 AX3000 ONU

As commonly recognized, the primary distinctions within Wi-Fi generations lie in their speed and performance capabilities, such as Wi-Fi5 AC1200, Wi-Fi6 AX1500, and Wi-Fi6 AX3000. These variations contribute to the suitability of each for different applications.


Wi-Fi 5 AC1200 ONUs:

Up to 1200Mbps, these ONUs are ideal for households or small businesses with moderate internet usage.

  • Home Use: Internet browsing, online gaming, and HD video streaming on smartphones, tablets, and laptops.

  • Small Office/Home Office: Email correspondence, web research, and video conferencing with limited simultaneous device connections

  • Small Café or Restaurant: Offering Wi-Fi access for patrons to browse the web, work on tasks, use social media, and more.


Wi-Fi 6 AX1500 ONUs:

Delivering enhanced throughput and capacity, AX1500 ONUs makes them suitable for households or businesses with high internet usage and a growing number of connected devices.

  • Smart Home: Perfect for various IoT devices such as smart thermostats, security cameras, and voice-controlled assistants, as well as 4K video streaming and less-latency online gaming .

  • Medium-Sized Office: Supports simultaneous internet usage for online collaboration, video conferencing, and cloud-based applications, with multiple employees.

  • Local Retail Store: Provide reliable connectivity for point-of-sale systems, inventory management, and customer engagement through smart screens.


Wi-Fi 6 AX3000 ONUs:

AX3000 elevates this further to ultra-fast speeds of up to 3000Mbps, catering to large-scale deployments and bandwidth-intensive applications.

  • High-Density Residential Complex: 4K/8K video streaming, intelligent home automation, smart community, and more.

  • Educational Institution: Providing campus-wide Wi-Fi coverage for online learning and projects across classrooms, libraries, and common areas, accommodating thousands of students, faculty, and staff members.

  • Hotel/Resort/Enterprise-level networks: Offering high-speed Wi-Fi access throughout the premises for diverse usage patterns from leisure to business activities.
