24 Designing for Next Gen Wi-Fi Applications QPF4800 Dual-Band Wi-Fi® 6 Front End Module QPF4800EVB-01 Evaluation Board QPF7219 Evaluation Board QPF7219 Wi-Fi Integrated Front End Module • Optimized for +5.0V operation • Broad range integrated DC power detector • Package dimensions: 4.0mm x 3.0mm • Acts as a reference design for the QPF4800 • Performance-focused on optimizing the 2.4GHz and 5.0GHz PAs • Multiple ways to offer access to the 28-pin signals of the QPF4800 • Operates within 2.402GHz to 2.472GHz frequency range • Supports 802.11ax Wi-Fi 6 standards • Evaluate the performance of the QPF7219 Wi-Fi integrated Front End Module • 2402MHz to 2472MHz frequency range • POUT=25dBm FCC restricted bandedge compliance • Optimized for 5V operation LEARN MORE > LEARN MORE > LEARN MORE > LEARN MORE > Bluetooth Mesh Another new mesh system is also being used in smart home application. Bluetooth® mesh allows for many- to-many device communications over Bluetooth radio. One advantage is that a Bluetooth mesh system would consumes less energy than Wi-Fi mesh. It passes the signal along through peers that are in range, creating a high tech version of the game telephone. Qorvo is "by the way, developing Bluetooth mesh because some of our customers are asking for it." "Wi-Fi 6 and 5G will continue to be as nicely complementary" The next generation of technology standard for cellular networks. "It will really get library networking even more pervasive and comprehensive, it will improve certain features that will improve the data rate and latency somewhat," Cees says. The main advantage is that the new networks will have greater bandwidth, allowing for faster download speeds; up to 10Gbits/s. It is able to provide this wide service by operating on three different frequency bands, each requiring a different antenna. Each antenna will compare download speed vs distance and service area to connect to the highest speed within that area. With these faster speeds, it is expected that this network could be used as general ISPs where cable internet is not available. China is leading the way with implementing its 5G infrastructure. "They are really charging ahead on 5G as a sort of protection of their smartphones and I expect that the United States will start catching up very rapidly," Cees says. China sees 5G as vital next step in its wireless technology on the global stage with current testing alone representing the largest 5G network in the world. A new smart city being built south of Beijing will use 5G for smart infrastructure and connected cars. This big jump in the 5G speed complements the speed that will be provided with Wi-Fi 6 home and office networks. It could be an uninterrupted day of wireless access between Wi-Fi 6 at homes and offices and 5G outside. We would notice big discrepancy if we could not have similar speeds in and out of the home. Conclusion Even before Wi-Fi was called Wi-Fi, Cees Links was involved with its creation. As Wi-Fi and cellular network technologies continue to evolve and improve, I hope that I never take being connected for granted. The next few years will be exciting as connectivity increases in availability and speed. Our devices are becoming smarter and more efficient. Think of a fully automated house, a smart city with connected cars, an augmented reality classroom, etc. https://bit.ly/2BT63mY https://bit.ly/3k5YdI3 https://bit.ly/33og0nY https://bit.ly/3a3B8kN
