What Is Wi-Fi 7? Of course! Wi-Fi 7 technology is the new generation of wireless communication technologies (Wi-Fi), officially known as IEEE 802.11be. It is a significant improvement compared to previous Wi-Fi technologies such as Wi-Fi 6 and Wi-Fi 5 (802.11ac).
Wi-Fi 7 improves connection speeds, reduce latency, and increases the efficiency of wireless networks, especially in crowded environments.
The most prominent features of Wi-Fi 7 technology
Theoretical Wi-Fi 7 speeds reach 30-40 gigabits per second (Gbps), compared to 9.6 gigabits per second for Wi-Fi 6.
1. Super speeds:
- These high speeds are ideal for applications that require large data transfer, such as virtual reality (VR), cloud gaming, and high resolution (8K) gaming.
2. Reduce data congestion:
- Wi-Fi 7 fully supports the 6 GHz bandwidth, besides the traditional 2.4 GHz and 5 GHz bands.
- 6 GHz band provides wider channels (up to 320 MHz), allowing faster and more efficient data transfer.
3. Multi-Link Operation (MLO) technology:
This technology allows devices to connect to several channels at the same time through different frequencies (2.4 GHz, 5 GHz, and 6 GHz).
This increases reliability and reduces latency, which makes them ideal for delay-sensitive applications, such as games and video calls.
4. Improved performance in crowded places:
- wi fi 7 supports advanced technologies such as MU-MIMO (Multi-User Multiple Input Multiple Output) and OFDMA (Orthogonal Frequency-Division Multiple Access) better.
- These technologies allow multiple devices to connect to the network at the same time without performance degradation.
5. Reducing latency:
- wi fi 7 reduces access time to at least 1 millisecond sometimes.
- This is important for applications that require immediate response, such as online games, virtual reality, and controlling smart devices.
6. Optimization of energy consumption:
- Despite the increased speeds, Wi-Fi 7 is more energy efficient, which extends the battery life of mobile devices.
Benefits of Wi-Fi 7 for smart homes
- Support for a greater number of devices: With the increase in the number of smart devices in homes (such as cameras, smart refrigerators, lighting systems, and audio aids), Wi-Fi 7 provides a more stable connection.
- Improved user experience: high speeds and low access times make playing HD video and cloud games smoother.
- Integration with future technology: Wi-Fi 7 supports future applications such as augmented reality (AR) and artificial intelligence (AI).

Discover mesh wifi how does it work 2025
Mesh wifi networks are a fundamental part of smart home infrastructure. Here comes the question: Is it time to upgrade to a mesh wi fi system for your home? The answer here depends on several factors. Is our Home large and has many Dead Zones or not? If the answer is yes, then you need to establish a mesh network system. Also, the type of devices we want to use, if we want to use devices that support the Zigbee or Z-Wave protocol, then we need to create a mesh wi fi system, because the devices don't work. And we all know that devices that support the Zigbee or Z-Wave protocol are energy-saving devices, meaning that you can change the battery every 6 months or a year for some devices, besides using a small Internet network, which saves Internet data. If […]
Zigbee: the Best Choice for Your Home Eco system 2025
what's zigbee protocol zigbee protocol is the most reliable and energy-efficient wireless communication method for the Internet, making it the most suitable for smart home devices, especially those that need to operate on batteries, such as sensors and smart door locks. Zigbee relies primarily on the 2.4 GHz frequency, which is a globally accepted frequency that ensures a balance between wide range and data transfer speed, as well as compatibility with various smart devices. The 2.4 GHz band is famous for its reliance on Wi-Fi and Bluetooth, which makes it compatible with many smart devices. zigbee gateway is also by synchronization with many devices up to 65,000 devices, which makes it capable of dealing with the most complex smart home systems. Using other devices inside the home rarely crowds the 2.4 GHz frequency, but ZigBee addresses this with simple algorithms, […]
