Discussion of key features of the field tests Conservative features • Measurements were performed in the rooms subjected to highest interference o Interference was generated from a high density of APs which is not observed in residential scenarios today, and is also considered unlikely in the future
Slide 18: Key learnings (1/2)
Key learnings (1/2) • The L6 GHz band (5945-6425 MHz) provides an important contribution to the performance delivered by Wi-Fi under scenarios of extreme network traffic and interference. • Indoor radio propagation for the 5 GHz and L6 GHz bands as compared with the 2.4 GHz band: o Propagation acros
