- londons_explore 6y agoMy 'home' network (with 10 people, 70 unique devices last month), there are currently only about 15 broadcast packets per minute, and they're all things that could be filtered/handled in wifi firmware (DHCP requests, multicast management traffic, STP stuff, ARP discovers, etc.). If other networks are like mine, then it would be reasonable for firmware to wake up for any unhandled thing, since the application processor might need to handle that unknown message, and to not wake up would leave the application developer sad...
