difference between WiFi7 and WiFi6

Since 2019, WiFi 6 networks have gradually become more prevalent, offering a significant speed boost compared to WiFi 5. During this period, router manufacturers and smartphone companies began heavily promoting WiFi 6 capabilities in their products, including vehicle gateways. Now, several years later, WiFi 7 is on the horizon, ready to be introduced and widely adopted.Let’s explore the differences between WiFi 7 and WiFi 6, particularly in the context of vehicle gateway

technology:

1. Speed WiFi 6 offers a maximum transmission rate of 9.6 Gbps, while WiFi 7 can achieve speeds up to 46 Gbps. This significant increase in speed will greatly enhance the performance of vehicle gateways, allowing for faster data transmission and improved connectivity in mobile environments.
2. Frequency Bands WiFi 6 primarily operates on 2.4 GHz, 5 GHz, and 6 GHz bands (the latter being part of the WiFi 6E upgrade). WiFi 7 expands this range, covering frequencies from 1 GHz to 7.25 GHz, including all the main bands used by WiFi 6. This broader spectrum will provide vehicle gateways with more flexibility in choosing the optimal frequency for different scenarios.
3. Channel Bandwidth WiFi 6 supports channel bandwidths of 20, 40, 80, 80+80, and 160 MHz. WiFi 7 increases the maximum channel bandwidth to 320 MHz. This wider bandwidth will allow vehicle gateways to handle more data simultaneously, improving overall network capacity.
4. Modulation Technique WiFi 6 uses 1024 QAM with OFDMA, while WiFi 7 employs 4096 QAM with OFDMA. This advancement in modulation techniques will enable vehicle gateways to transmit more data in each signal, further enhancing efficiency and speed.
5. MIMO (Multiple Input Multiple Output) WiFi 6 supports MU-MIMO and can handle 8 simultaneous data streams. WiFi 7 introduces CMU-MIMO and can manage up to 16 simultaneous data streams. This improvement will allow vehicle gateways to communicate with more devices concurrently, enhancing the overall network performance in complex mobile environments.
6. Standard WiFi 6 is based on the IEEE 802.11ax standard, while WiFi 7 follows the IEEE 802.11be standard. These standards define the technical specifications and capabilities of each WiFi generation, including those relevant to vehicle gateway applications.

In summary, WiFi 7 represents a significant upgrade over WiFi 6 across various parameters. For vehicle gateways, this translates to faster speeds and lower latency, which are crucial for mobile connectivity and IoT applications in the automotive sector.Many router manufacturers have already begun launching WiFi 7 routers, and some smartphone companies have also introduced devices supporting WiFi 7. This progression in wireless technology will lead to an enhanced browsing experience and improved performance for vehicle gateways.As WiFi 7 becomes more widespread, we can expect to see its implementation in various vehicle gateway solutions, enabling faster and more reliable mobile connectivity for automotive applications, fleet management systems, and other IoT devices in the transportation sector.
