The device must only perform passive scanning to find a "master device" (e.g. So, a client device can avoid implementing radar detection as long as the manufacturer certifies that it will not operate in ad-hoc or peer-to-peer mode.
#FCC ID LOOKUP BY VIN UPDATE#
If Apple does drop a software update at a later date for the iPad 3, we could see Wi-Fi specs bumped to: Broadcom also lists concurrent dual-band capability for Wi-Fi client access on one band while simultaneously using Wi-Fi Direct or Wireless Display on the other band using what they call "advanced switching techniques." This would be an intriguing choice since that chip offers single-stream 802.11n, dual-band operation, and 40MHz wide channels. Broadcom product literature even includes very "Apple-esque" verbiage around highly mobile devices and push-email. If Apple is using another Broadcom combo chip, which is highly likely, it could be the BCM4334 which is designed for smartphones and tablets. We know for sure from the FCC test reports that it support Bluetooth 4.0, which should be a major improvement over 2.1 + EDR found in the iPad 2. My guess is that there are significant hardware improvements under the hood, which Apple may not be leveraging at time of initial release but may drop an update later on down the road. However, once iPad 3 devices start shipping on 16-Mar there should be an iFixit teardown to give us insight.

We won't know for sure what chipset is being used because the FCC internal photos are currently marked "Confidential" until 0. The combo Wi-Fi and Bluetooth chipset used by the iPad 3 is definitely NOT the same Broadcom chip used in the iPad 2 and iPhone 4 (which used the Broadcom BCM43291HKUBC).
