I see this design as being increasingly relevant because of the way major electronics manufacturers are building “best of class” personal-electronics devices in all of the device classes (mobile phone, personal digital assistant, personal media player, etc) that they offer such devices in. The main issue that has plagued people who use these devices is the increased likelihood of the device’s battery dying on them when they want to get the best out of the device.
I see this design as a step in the right direction regarding long battery run-time for these devices because, as the article has said, of integrating the WiFi N, Bluetooth and FM radio circuitry in to the one circuit with improved power consumption. This is certainly important if the device is to be used in a wireless network and with a Bluetooth headset for example.
It also encourages device builders to consider not just Internet-hosted services but network-based services like DLNA-based media server / control / play functionality. Now that this version of the chip integrates low-power FM transmission, this could appeal to the idea of a “music phone” or personal media player with DLNA media play functionality playing music from its own collection or a DLNA network media server through an ordinary FM radio.
At least this chipset will be a step in the right direction for “raising the bar” in personal-electronics design.
