Measurement Software is Critical in Wi-Fi 7 Testing
Can the world go a day without using wireless connectivity? Most cannot because much of our daily activities depends on wireless solutions. The world depends on wireless connectivity, from jobs, school, or daily communications. Advancements in wireless connectivity have helped advance other technologies, research, and innovative ideas. Wireless devices push technology forward in an evolving world.
T
oday there is high-performance wireless solutions such as 5G and Wi-Fi 5, and some industries are using 802.11ax, also known as Wi-Fi 6. Advancements in wireless solutions such as 6G, IEEE 802.11be, and Wi-Fi 7 are continuous and rapid. Although, with previous generations of wireless standards, one would think that since performance is improving, so would the ease of feasibility in meeting regulatory standards. This has been proven to not be the case.

improving, but meeting regulatory standards is becoming a challenge if not prepared correctly. To perform at a high capacity, users need to ensure they are testing with high-performance products that can meet new standards and regulations. For Wi-Fi 7, this is no different; first let us understand what is new to the standard, the wireless signal challenges these new rules impose, and what type of test software would assist in resolving those challenges.
History of 802.11
Wireless local-area network (WLAN) products and systems began with 802.11b, 802.11g, and 802.11a standards, providing throughput enhancements over the original 802.11 standard introduced in 1997. Wireless technology continues to evolve by integrating the latest technologies to meet the requirements of new applications and the need for higher data rates. The goal is to improve spectrum utilisation, throughput, and user experience.
