However, for users with 2.4 GHz networks, gain on that band is important. In addition, multimedia streaming seems to be the ideal use case for 5 GHz WLAN thanks to both the ability to run 40 MHz channels and deal with less congestion. If you're living in the Apple ecosystem with an Airport Extreme or have a 5 GHz AP, this previously is something you could've not noticed entirely. One of the main complaints that I read online of the Apple TV 2 was its performance on 2.4 GHz. The maximum PHY rate and presence of 2.4 and 5 GHz band support is unchanged from Apple TV 2. Seeing two RF chains, you might be led to think that the Apple TV 3 has 2x2:2, however this is not the case as the device still will only connect at 65 Mbps - single spatial stream, 20 MHz wide channels with the long guard interval. In addition, the Apple TV 3 also moves from Broadcom's BCM4329 802.11a/b/g/n and BT 2.0+EDR combo chip to BCM4330 802.11a/b/g/n and BT 4.0 combo chip which we've seen in the iPad 3, iPhone 4S, and countless other mobile devices. The second is adjacent and shares the same ground plane / metal layer.Īntenna 1 (Encircled in blue), Antenna 2 (Encircled in red) The first appears to be of similar design to the Apple TV 2, and it's obvious from visual inspection that this is the case.

I touched on the fact that the Apple TV 3 now has two WiFi antennas printed on its PCB.
