What are the key differences between WiFi 7 and previous generations?
6 GHz
Unlike previous generations, WiFi 7 utilises the 6 GHz frequency band, providing access to uncongested spectrum and wider channels. This not only improves overall capacity but also reduces interference in densely populated areas with numerous wireless devices.
Automated Frequency Coordination (AFC)
WiFi 7 enhances range and coverage with Automated Frequency Coordination (AFC). By cross-referencing local links to identify available channels, it minimises interference with existing systems. This is ideal for large offices, warehouses, and outdoor areas where reliable connectivity is essential.
Preamble puncturing
Preamble puncturing is now mandatory for WiFi 7. Also called “punctured transmission,” it allows access points and clients to avoid interference by segmenting parts of the channel while using the rest. This helps maintain WiFi 7’s high throughput and low latency despite interference.
Energy efficiency
WiFi 7 excels in energy efficiency with advanced power management and data transmission techniques. This allows devices to run longer on battery power, making WiFi 7 ideal for IoT applications and mobile devices.
Multi-user
WiFi 7 boosts multi-user capabilities, letting more devices communicate simultaneously without performance loss. Advanced scheduling algorithms and spatial reuse techniques enable more efficient bandwidth use and reduce device contention.
Technical dive into WiFi 7
Exclusive to 6 GHz, this channel allows for more simultaneous data transmission.
Offers 20% higher transmission rates than WiFi 6’s 1024 QAM, enhancing efficiency.
Doubles the 256 units in WiFi 6, consolidating more data into a single frame and reducing transmission overhead.
Twice as many as WiFi 6, enabling more efficient data transmission and increased capacity.
Provides more efficient load balancing across links for greater throughput and reliability.
Enhances spectral efficiency by dividing channel widths into smaller, more efficient subchannels with multiuser capability.
Key WiFi 7 use cases
High-density public venues
Boasting unmatched speeds and enhanced performance, WiFi 7 is capable of supporting high-density public venues like stadiums, airports, and convention centres. It allows thousands of devices to connect simultaneously without lag or congestion.
IoT
WiFi 7’s increased bandwidth and reduced latency make it an ideal solution for seamlessly connecting and managing large-scale Internet of Things (IoT) deployments. Businesses can utilise WiFi 7 to efficiently monitor and control extensive networks of IoT devices, enabling real-time data collection, analysis, and automation.
Extended Reality (XR)
These immersive technologies demand high-speed, low-latency wireless connectivity to provide the best user experience. WiFi 7’s capabilities allow businesses to develop highly engaging AR/VR applications for training, product visualisation, and remote collaboration, thereby enhancing productivity and efficiency without connectivity challenges.
Cloud Computing
With its ability to transfer large amounts of data at lightning-fast speeds, WiFi 7 can facilitate seamless cloud integration, allowing businesses to more effectively leverage cloud-based services, storage, and computing resources. This can streamline operations, reduce infrastructure costs, and enhance scalability.
