AUGUST 2024TELECOM BUSINESS REVIEW 195G and Wi-Fi 6/6E will Coexist and are ComplementaryIt is important to realize that 5G and Wi-Fi 6/6E are not competing technologies but complementary ones. In fact, they are designed to work in harmony and make our connected experience a seamless one. The "hand-off" of mobile data from 5G networks to Wi-Fi is key to this seamless connectivity. In a typical day our mobile phone may switch many times from 5G cellular networks when we are outdoors or in the car, to Wi-Fi networks when we are at home, in the office or in public spaces such as malls, airports and sports stadiums.The sheer volume of all this mobile data that needs to be handed off to Wi-Fi networks is quite staggering ­ more than 100 exabytes per month are projected to be offloaded from cellular networks in 2022 alone.The combination of 5G and Wi-Fi 6/6E will be a game-changer for seamless, wireless connectivity. However, although it may sound simple conceptually, ensuring these two technologies can coexist in the same or adjacent frequency bands will make the parallel configuration of these networks extremely challenging. Specifically, the technical demands on the filters that allow signals in the band to be separated are becoming increasingly challenging. Developers are now incorporating films that have higher scandium doping levels (typically >20 percent) in aluminum nitride as it delivers improved device performance. This is an area in which Lam Research is working closely with our customers to collaboratively develop and deliver solutions that meet these challenges. As with 5G, the fact that Wi-Fi 6 and 6E can run at higher frequencies with wide bandwidth significantly differentiates them from prior generations of Wi-FiDavid Haynes
